How did the information transmitted by secret radio stations work during the civil war in China? Thank you for your title. It's just ordinary radio transmission. It's just that the encryption method and frequency are discussed in advance.

What is love really like? Thank you. Love is painful. Why do you say it hurts? . . Because if you have it, everyone wants it. . You begin to taste the taste of love. I can't tell you the ups and downs. . You will be happier than when you are alone. . Will be more sad than a person. Just because you have the other half you care about. He or she smiled. Worried. Bitter. Are deeply imprinted in your mind, and you will care more about his (her) feelings than him (her). Just like you did in the TV series. . . The ups and downs of the plot. Let you intersect. I worried you. . Let you move. . . Everything you have never felt is just love. That's why I said his egg hurts. . . Rough waves can stir our calm hearts. It also makes us feel that we are the happiest people in the world.

What is the desert like? For example, thank you 1, Taklimakan desert, which means "a place where you can't get in and out" in Uighur. People usually call it "the sea of death". It is located in the center of Tarim Basin in southern Xinjiang, covering an area of 324,000 kilometers. It is the largest desert in China, second only to the Sahara desert in Africa, and the second largest mobile desert in the world. Among the major deserts in the world, the Taklimakan Desert is the most mysterious and fascinating one. The desert center is a typical continental climate, with heavy wind and sand, great temperature change and little precipitation throughout the year. There are frequent sandstorms here, and the sand dunes have strange shapes, up to 250 meters. The most wonderful thing is two red and white sand dunes, the famous Holy Tomb Mountain. The top of the mountain was eroded by the wind to form a "big mushroom". Due to the ups and downs of the earth's crust, sedimentary rocks composed of red sandstone and white gypsum are exposed to the ground, forming a bright red and white landscape. Around the desert, along the banks of the Yarkant River, Tarim River, Hotan River and Qierqin River, dense Populus euphratica forests and willow shrubs grow and develop, forming a green island in the sand sea. "Especially on the banks of the Hetian River that runs through the desert, there are many kinds of sandy weeds, such as longevity reeds and Populus euphratica, which form a' green corridor' in the desert. The promenade is full of flowing water and connected with oases. Animals such as rabbits and birds live in forest belts, which also adds a little vitality to the "sea of death". The investigation also found that the desert is rich in groundwater reserves, which is conducive to development. Where there is water, there is life. Scientific investigation overthrew the "life forbidden zone theory". In the vast desert, countless ancient city sites have been discovered so far, and the printed cotton cloth and embroidery of the Eastern Han Dynasty have been unearthed at the Niya site. 2. Gurbantunggut Desert The second largest desert in China. It is located between 4415 ′ ~ 46 50 ′ north latitude and 84 50 ′ ~ 9120 ′ east longitude. Located in the middle of Junggar basin, with an area of 48,800 square kilometers. It consists of four deserts, namely, the Bugle Desert in Bougourd in the west, the Huojingneixin Desert in the east, the Dezosoten Ellison Desert in the middle and the Kubbe-Akkum Desert in the north. Junggar basin belongs to temperate arid desert. The annual precipitation is 70 ~ 150 mm, and there is snow in winter. There is a little more precipitation in spring and early summer, and it is evenly distributed in the middle of the year. Most of the desert is fixed and semi-fixed sand dunes, accounting for 97% of the whole desert area, forming the largest fixed and semi-fixed desert in China. The vegetation coverage on the fixed dune is 40 ~ 50%, and the semi-fixed dune is 15 ~ 25%, which is an excellent winter grassland. There are 100 kinds of plants in the desert. The floristic elements are in the transitional stage from Central Asia to Central Asia desert. In the west and middle of the desert, the species of desert vegetation flora in Central Asia are dominant, such as Haloxylon ammodendron, wormwood, Artemisia ordosica, Carex and many short-lived plants. On the eastern and southern edges of the desert, there are many species of plants in Central Asia, such as Haloxylon ammodendron, ephedra, flower sticks and so on. Haloxylon ammodendron in Gurbantunggut Desert covers an area of 6.5438+0 million hectares, forming a "desert jungle" in the ancient lake plain and the lower reaches of the river delta. The sand in the desert mainly comes from the alluvial sand layer of the river at the northern foot of Tianshan Mountain. The most representative sand dune type in the desert is sand ridge, which accounts for more than 50% of the desert area. The planar shape of the sand ridge is dendritic. Its length ranges from several hundred meters to more than ten kilometers, its height ranges from 10 ~ 50 meters, and it is high in the south and low in the north. In the north-central desert, the arrangement of sand ridges is generally north-south, and the southeast desert is northwest-southeast. There are sand ridges in the southwest of the desert-honeycomb sand dunes and honeycomb sand dunes, and several tall composite sand ridges appear in the south. Mobile dunes are concentrated in the eastern part of the desert, mostly belonging to crescent dunes and dune chains. Wind erosion landforms are abnormally developed near several tuyeres in the western desert, among which the "Wind City" in Wuerhe is the most famous. Aeolian sand is widely distributed in the desert. Gray-brown desert soil developed in the southern edge plain of the desert, and was reclaimed in a large area after 1949. Human activities have destroyed natural vegetation, leading to the resurgence of quicksand and sandstorm on the edge of desert. There is Haloxylon ammodendron nature reserve in Ganjiahu Lake on the western edge of the desert, which is the only nature reserve established to protect desert vegetation in China. 3. Tengger Desert is located in the southwest of Alashan Zuo Qi in Alashan League, in the middle of Gansu, east to Helan Mountain, south to the Great Wall and west to Laishan Mountain in Ya Bu. Tengger is Mongolian, which means boundless as the sky. Tengger Desert is more than1.200m above sea level, with a total area of 36,700 square kilometers. In the desert, sand dunes, lake basins, mountains, residual hills and flat land are intertwined, of which sand dunes account for more than 70%, mostly crescent-shaped sand dune chains, with a height of 10-30 meters, and often move to the southeast. There are more than 400 large and small lake basins in Tengger Desert, most of which are freshwater lakes, which can be drunk by people and animals. Surrounded by lush plants, it is the main pasture, suitable for desert exploration, sightseeing and other tourism activities. 4. Wulanbuhe Desert is located in the Wulanbuhe Desert in the west of Inner Mongolia, the east of Ningxia and the west bank of the Yellow River, spanning Alashan League and Bayannaoer League, with an area of10.4 million square kilometers. Historically, it used to be a rich grassland in Ran Ran, with the shade of "prosperous population, loose horses and cattle" and "general marching beyond the Great Wall, full of apricot flowers". At present, the land types are composed of sand dunes, sandy wasteland, cultivated land and small grasslands. The sand dunes here are colorful: the accumulated sand dunes are distributed in Aobaotu, Aobaoluge and Jilantai areas; Baiyun Aobao distributes ridge dunes; Lattice crescent dunes are distributed in Rigai, Aolun brug and Aobaotu. Crescent dunes are distributed in Hatengtao Sea. The desert in Wulanbu and Wuhai area of Inner Mongolia is connected with the desert water of the Yellow River. Whenever the sun sets, the forest is sparkling, and the "long river sunset" and "lonely smoke in the desert" constitute a magnificent landscape painting. 5. Kubuqi means "bowstring" in Mongolian. It is 400 kilometers long, 50 kilometers wide, and the sand dunes are 10-60 meters high, like a yellow dragon lying in the northern part of Ordos Plateau, across the three banners in Inner Mongolia. We paid our respects to Kubuqi in Hangjinqi section. Kubuqi Desert is the sixth largest desert in China and the closest desert to Beijing. One of the sources of sandstorms that Beijing people talk about this spring is the Kubuqi Desert. 6. Hunshandake is Mongolian, meaning "solitary colt". According to legend, Genghis Khan rode his favorite "one-legged horse" when he went west. It is named after this sandy land. Hunshandake Sandy Land is located in the south-central part of Xilin Gol Grassland, with an east-west trend, stretching for more than 300 kilometers, with a total area of 21.4000 square kilometers. Sand dunes undulate on the sand, with lowlands and beaches between them. This sandy land is a famous water desert in China. There are many small lakes, blisters and sand springs in the sand, and the springs emerge from the sand and converge into rivers. Most of these rivers flow into Gogestai River, some only flow into bubbles, and some only flow into seasonal rivers. Hunshandake sandy land is rich in aquatic plants, with peculiar landscape and beautiful scenery. Some people call it "Jiangnan beyond the Great Wall", while others call it "Garden Desert". There are many wild animal resources, which are spawning and breeding grounds for migratory birds, and there are many rare plants and medicinal materials. 7. Badain Jaran Desert is located in the north of Alxa Right Banner, Inner Mongolia Autonomous Region. It is about 270 kilometers long from east to west and 220 kilometers wide from north to south, covering an area of 47,000 square kilometers. It is the third largest desert in China, with more than 65438+100000 square kilometers in the northwest. So far, there are no human footprints. It is the only desert with dense distribution of tall sand mountains in the world, with an altitude of 1, 200 ~ 1, 700 meters. The relative height of sand dunes can reach more than 500 meters, which is the highest in desert in the world and is called "Desert Everest". 8. Horqin Sandy Land is the largest of the four sandy lands in China, with a total area of 42,300 square kilometers. It is located at the junction of northeast China and north China.

What are friends like? Thank you. It is enough to know everything about life. It is not only the care and help of friends in life, but also the comfort and satisfaction of the soul. Patiently understand the feelings of others, be considerate of others, and don't bother if your friends have any shortcomings. No one is perfect. In addition, remember, don't do to others what you don't want others to do to you. In fact, it is very simple, understanding, trusting, communicating, sincere and caring. Be nice to others first, and then you will find true friends around you. Won't make you feel cheated. If you can't wait to tell him anything, then he is your true friend. To put it simply, the first person you think of when you are sad, the person you don't have to pretend in front of him, is a friend who shares weal and woe, shares weal and woe, and can talk to each other without reservation.

What is love like? Thank you. When you fall in love with someone, don't care about the romance of love and many ways of love. Everyone loves in different ways. Don't be insatiable. If you are insatiable, you will lose your rare true love. Some people say that love will not last long, but I think this is wrong. Love will last for a long time, because when you don't protect true love, it will lead to short-lived love, which you think will not last. Love a person to trust each other, love a person to understand each other, love a person to be tolerant, love a person to be broad-minded, love a person to respect each other's ideas and opinions, love a person to support him (her) behind his back, not to stop him (her) from loving him (her), don't complain when he (she) can't accompany you, tell him (her) with a smile. Don't let him (her) know that he (she) loves someone too much ~ ~ ~ too much. Maybe some people can't do it. What is important is that love should be selfless, clean and pure, and willing to do anything for him (her). When you are in love, make him (her) happy, as long as he (she) is happy. In fact, sometimes after separation, I will find out how much I love him. In fact, many boys don't know that girls turn around after being angry with them, but just keep sobbing. In fact, many boys don't know that girls are never really angry with them, because she really likes and cares about him. In fact, many boys don't know that girls only nag at boys they like and only play with people they like. You know, if she doesn't like you, she won't care about you at all, lest you do something wrong. You know, she doesn't like you, she won't be angry with you at all, and she won't be spoiled for you. She is a lady in front of others. You know, if she doesn't like you, you can't make her cry at all, even if she is angry, it won't last more than two days. And all this is just because she likes you, and all this is because you don't care about her enough and don't understand her enough. So, you often quarrel, you think she has a bad temper, and she thinks you are not accommodating her enough. So, you are always cold war. You think she doesn't like you, she thinks you don't care about her. Therefore, you always miss each other inexplicably. Perhaps passing by is a sad helplessness and happiness. You know, sadness is still a kind of beauty, beauty is gorgeous, and sadness and vicissitudes are even more beautiful. Because she likes you, she occasionally gets angry with you and often acts like a spoiled brat. Because she likes you, she will be angry with you; And because she likes you, she won't be angry for long. You know, every girl's heart is made of crystal, crystal clear, but it is easy to get hurt and broken. Do you know that every girl is defenseless? You broke into her heart so easily, leaving only harm when you left. She never knew that no one in the world could make her cry, because the one who really deserves her tears is reluctant to make her cry. She will be very reserved, she will be proud, she will be indifferent, she always says you go away, but her heart keeps telling you to stay. Please open your ears and your heart to listen to her inner voice, not her duplicity. She will watch you turn around, and then she will turn around with you. When you pass by sideways, you can't see her tears, and they all pour on your face. If you like her, please spend more time with her; If you like her, please spoil her more; If you like her, please let her go. If you like her, please listen to her inner voice. It's crying-please hug her. In love, we always hurt each other, as if only in this way can we prove that our love is fierce and powerful. However, love is not right or wrong; No one in love is more than me, and I am less than you. You love her, and she loves you. That's enough. Don't try to hurt each other and make them more vulnerable and sad. You love each other, what you need is warmth, happiness, sweetness and happiness, not harm. Don't declare war with silence, don't give in to the other side, and don't leave without saying anything. You know, when you left, your eyes were foggy and her eyes were full of tears. The calmer the war, the more it spreads. This is the cold war and mutual harm-no matter how they get back together, those wounds have existed and cannot be erased. Please give her a hug, and use your hug to resolve the sadness in her heart and the tears in her eyes. She likes you, she will never refuse your hug, she will only be afraid of your indifference and turn to silence. Remember, people who love each other should not declare war easily, because the damage brought by the cold war is unexpected. Please also remember that as long as you like her, there is nothing you can't accept. As long as you like her, you like everything about her. Then all her little temper, bad temper and bad habits are spoiled in your eyes. Please also remember that she likes you, what she needs is not that you really turn around, and what she said is not what she really means. She just wants you to spoil her and hug her, even if she doesn't apologize.

What is the international situation now? Thanks to the constraints of other big countries, countries such as the United States, Britain and France will only provoke small-scale wars, and it is difficult to do much. On the one hand, bin Laden's death will win people's hearts, but it will lead to greater revenge ... Gaddafi and the * * * army may become the second Al Qaeda, or they may become the second Castro. China, for example, is constantly practicing and ready to deal with the pressure from India, Myanmar, Japan and South Korea ... International comparison. Hope to adopt
