Others have no emotions, but I have negative emotions.
Or analyze it in context.
Question 2: What does it mean to give a negative attitude? We live in this world and can't just ask others for it.
You have to pay for others, too You've done something for others,
Others will pay for you, just like giving up and giving up, that's what it means.
Negative means the opposite.
Question 3: What are the negative bias characteristics? Draw a risk profit and loss chart.
A bullish bull has unlimited profits when the underlying asset price rises, and only margin when it falls.
B bearish bulls, the rising risk of the underlying asset price is only margin, and it is profitable when it falls.
C is bear market option arbitrage, with limited risks and benefits.
D bearish bears, when the underlying asset price rises, the profit is only a margin, limited, and when the price falls, the risk of loss is infinite.
So choose d, negative bias, profit and loss bias.
Question 4: What do negative ions mean? Negative ion air is made up of countless molecules. Due to the influence of cosmic rays, ultraviolet rays, soil and air radiation in nature, some air molecules will release electrons. Under normal atmospheric pressure, the released electrons quickly combine with neutral molecules in the air to become negative ions, or anions. Negative ions are negatively charged gas ions in the air. Some people call it air vitamin, and think that it, like food vitamin, has a very important influence on the life activities of human body and other creatures. Some people even think that negative air ions are related to longevity, and call them longevity elements. What effect does negative ion have on human body? The main effects are as follows: 1, which can strengthen the function of cerebral cortex and brain activity, boost the spirit, improve work efficiency and improve sleep quality. Negative ions can also strengthen the oxidation process of brain tissue, so that brain tissue can get more oxygen. 2. This is the influence on the cardiovascular system. According to scholars' observation, negative ions can obviously dilate blood vessels, relieve arterial vasospasm and achieve the purpose of lowering blood pressure. Negative ions are also beneficial to improve cardiac function and myocardial nutrition, and are beneficial to the rehabilitation of patients with hypertension and cardiovascular and cerebrovascular diseases. 3. It is the influence on the blood system. Studies have confirmed that negative ions can slow down blood bank, prolong coagulation time and increase oxygen content in blood, which is beneficial to the transportation, absorption and utilization of blood oxygen. 4. Negative ions have the most obvious effect on respiratory system. This is because negative ions enter the human body through the respiratory tract and can improve people's vital capacity. After testing, inhaling negative air ions in the glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 2%, while the amount of carbon dioxide discharged can increase by 14.5%, so negative air ions can improve and increase lung function.
Question 5: What does the load status mean? This is beyond my ability.
Question 6: What does the negative ion of hair dryer mean? Negative ion blower is mainly equipped with negative ion generator and semiconductor refrigeration device. In this way, when the hair dryer works, it can generate negatively charged ion particles (generated by the negative ion generator) and water vapor particles (generated by the semiconductor refrigeration device) to neutralize the common positive charges in the hair, so as to straighten out the messy hair, make it fit smoothly and eliminate static electricity. Make hair smoother and easier to comb, and the styling effect is more ideal. [ 1]
When the hair dryer works, it will generate heat, and the blowing wind will dry the hair. It is inevitable to use a comb in use, so that the hair is prone to generate static electricity, which makes the hair deformed, bent or tilted. The net wire is specially designed in the negative ion fan, and the wind blown by the negative ion generator will carry negative ions, so it will not generate static electricity, thus not hurting the hair.
Working principle editing
The negative ion generator is a device that generates negative ions in the air. After the input DC or AC is processed by EMI processing circuit and lightning protection circuit, the pulse circuit will overvoltage and limit the current. The high and low voltage isolation wires are upgraded to AC high voltage, and then the pure DC negative voltage is obtained after rectification and filtering by special electronic materials. A negative DC voltage is connected to a release tip made of metal or carbon, and a large number of electrons (e-) are released at a high speed by using a high DC voltage at the tip. However, electrons can't exist in the air for a long time (the existing electron lifetime is only ns), and they will be immediately captured by oxygen molecules (O2) in the air, thus generating air negative ions. It is reported that there is a more advanced negative ion release tip: nano fullerene negative ion release tip, which can produce pure negative ions.
Air negative ions can be divided into light, medium and heavy ions by volume. Light ions have a diameter of about 0.00000 1cm, and move faster in the electric field, ranging from1~ 2cm2/v.s. In the natural or ordinary environment, light ions are small particle negative ions, while heavy negative ions have a diameter of about 0.000 1cm, and move slower in the electric field. In nature or ordinary environment, the size and activity of negative ions with large particle size less than 0.04cm2/(v.s) are between those of light and heavy ions. Among them, negative ions with smaller particle size have good biological activity and easily enter the human body through the blood-brain barrier to exert their biological effects. Traditional negative ion generation technology can't generate negative ions with small particle size, and only negative ion converter technology and nano-fullerene negative ion releaser technology can generate negative ions with small particle size.

2 health role editor
Negative ions have health care function. In different areas, the number of negative ions in the air is quite large, which has been measured. According to the number of negative ions contained in air per cubic centimeter, there are about 1000 in rural areas, 4,000 in coastal areas and more than 5,000 near fountains and waterfalls. Because of the high content of negative ions in the air in these places, people feel energetic. However, in some densely populated cities, the concentration of negative ions is relatively low due to serious air pollution.
Some environmental protection departments have also carried out tests. In cities, there are hundreds of negative ions per cubic centimeter outdoors, even less indoors, not exceeding 1000! Especially there are few negative ions beside TV sets and computers. Studying and working in this environment for a long time is often very tired and unhealthy.
Why do negative ions have health care functions? Medical experts believe that there are three reasons through research.
First of all, in the living body, each cell is like a miniature battery, and there is a potential difference of 50~90 millivolts inside and outside its membrane. It is precisely because of the constant charging and discharging of these "batteries". The nervous system of the body can transmit visual and auditory signals to the brain or transmit instructions from the brain to various organs of the body. The electrical activity of body tissues needs to be maintained by continuously supplementing negative ions. Once the body is not supplemented by negative ions, it will affect normal physiological activities, leading to chest tightness, dizziness and even illness.
Secondly, because viruses that attack human cells are usually negatively charged, if human cells are also negatively charged, they will be rejected by the same sex. Let the virus lose its ability to attack living cells.
Finally, negative ions can also enter the lungs through breathing, and have a neutral physiological health care effect on the human body through the direct interaction between human tissues and the interaction between nerve reflex and body fluids. ...& gt& gt
Question 7: What are the formulas for calculating the peak value and skewness? Zhaosf588 Hello! I hope my information can help you!
Skewness and kurtosis are statistics used to describe the distribution characteristics of data.
Skewness -SK is used to study the positive/negative skewness of waveform. It can be calculated by arithmetic mean, mode or median, and can also be calculated by dynamic difference.
Peak state quantity -Ku is used to study the positive/negative peak state of waveform. It can be calculated by two percentiles or by dynamic difference.
Question 8: What do negative oxygen ions mean? Most of the free electrons produced by the ionization of molecules in the air under the action of high pressure or strong rays are obtained from oxygen. A negatively charged oxygen ion [1] thus gains some electrons and is called "negative oxygen ion". (The other is the health killer superoxide radical) Negative oxygen ions are called "air vitamins", which can affect people's physiological activities through their nervous system and blood circulation.
However, negative ions with smaller particle size have good biological activity and easily enter the human body through the blood-brain barrier to exert their biological effects.
According to Xinhua News Agency and Guangming Daily, the patented technology of small particle size negative ions was successfully developed in 2009, and the national patent was obtained on 20 10, namely the patented technology of negative ion converter and nano-fullerene negative ion releaser.
