1. 1928 Provisional Rules for Inspection of Export Commodities ***8, which stipulates: In order to protect the domestic and foreign industrial and commercial interests, improve the international trade credit and increase the value of commodities, the Commodity Import and Export Inspection Bureau was established to conduct inspection during the import and export of commodities.
3. 1992 10 The State Commodity Inspection Bureau further issued the Regulations for the Implementation of the Import and Export Commodity Inspection Law of People's Republic of China (PRC). On April 28th, 2002, the 27th meeting of the 9th the National People's Congress Standing Committee (NPCSC) took the economic reform as the breakthrough point and deliberated and adopted the revised new commodity inspection law.
The promulgation and implementation of the new commodity inspection law is an important symbol of the legal construction of quality supervision, inspection and quarantine in China.
6. The commonly used inspection methods of import and export commodities can be divided into sensory inspection method, sampling inspection method, chemical inspection method, biological inspection method and instrumental analysis method, and instrumental analysis method is the principle of the above inspection methods. ?
7. Sensory inspection is a method to inspect and identify the present situation or some characteristics of commodities by using the functions of sensory organs (eyes, ears, nose, tongue and hands) such as vision, hearing, smell, taste and touch of inspectors. ?
8. Technical sensory inspection only depends on the sensitivity of various senses of inspectors and years of accumulated experience.
9. 1664 The British government initiated the national inspection and management system for export commodities.
10.20th century, commodity inspection authorities were generally established in relatively developed western countries. ?
From 1 1. 1405 to 1433, Zheng He made seven voyages to the Western Ocean. At that time, the international trade was to look at the goods on the spot, and the quality and price of the goods were decided by the buyers and sellers on the spot. ?
On 12. 190 1, representatives of foreign factories in Shanghai cooperated with cotton exporters to negotiate with the Qing government to set up a water vapor inspection office on the grounds of solving the problem of cotton adulteration.
13. Englishman Luo set up a special water vapor inspection office in Hangzhou. Because the institute was too picky, it was destroyed by our cotton farmers at the beginning of 1902.
14. 1902, Cheng Ding, the chairman of Shanghai cotton industry, applied to Shanghai Road to set up a cotton inspection bureau, and formally established the Shanghai Cotton and Flower Inspection Bureau in the Shanghai Flower Industry Office, which is the first inspection institution in China to inspect and ban cotton doping.
15.19321214 At that time, the national government promulgated the Commodity Inspection Law, which was the first law on the inspection of import and export commodities in China. This is the first time that China has carried out statutory inspection on import and export commodities. ?
On 16. 1980, the Commodity Inspection Bureau of the Ministry of Foreign Trade was changed to the General Administration of Import and Export Commodity Inspection of People's Republic of China (PRC) (deputy minister level), and the establishment of commodity inspection bureaus in various places was placed under the central government, and a vertical leadership system with dual leadership of the central and local governments and central leadership as the mainstay was implemented. ?
17. Accurate and consistent values refer to the same values measured by different measuring instruments, if the measurement results are unified within the required accurate range.
18. Is the national measurement standard stipulated as the basis for unifying national values?
19. Before evaluating the measurement characteristics, the inspectors must first inspect the non-measurement characteristics such as the structure and working state of the measuring instruments, and then calibrate them after passing the inspection. ?
20. Calibration is a set of operations to determine the relationship between the indicated value of measuring instrument or measuring device or the value represented by physical quantity and the corresponding measured known value under specified conditions. ?
2 1. Statistical regularity refers to some regularity of random events when a small number of repeated experiments are carried out.
22. A sample is a collection of individuals selected from a population.
23. The sample size is the number of individuals included in the population. Often represented by n?
24. A basic feature of quantity is that its size varies with the selected unit of measurement.
25. Metrology is a series of operations aimed at determining quality. ?
26. Static quantity can be considered to be invariant with time when measured, and its measurement result can be expressed by a value of a computing instrument. ?
27. The unit of measurement is the specific quantity agreed upon, and the quantity with the same dimension is expressed by quantity. ?
28. The practical significance of dimension is to quantitatively determine the relationship between quantities, especially the relationship between the basic quantity and the derived quantity, and the numerical value is not important.
29. In the quantitative system, it is basically agreed that they are independent of each other, but the corresponding basic units are not all independent of each other.
30. The dimension is the product of the power of the basic quantity in the quantity system to express the expression of a quantity in the quantity system.
3 1.SI derived units are units derived from Si baSIc units and multiple units according to the definition equation.
32. Is the inspection of import and export commodities a necessary means to control the quantity of imported commodities and safeguard the fundamental interests of the country?
33. Inspection of import and export commodities is the need to provide intermediary proof for international trade and promote the smooth progress of international trade?
34. Import and export commodity inspection is divided into administrative entrusted inspection and civil entrusted inspection according to different nature. 35. All experimental results have errors, which exist in all scientific experiments from beginning to end. ?
36. The true values of various physical quantities measured in the inspection of import and export commodities can be directly measured.
37. Absolute error is the difference between the detected value and the relatively true value.
38. Relative deviation and relative error are the same and cannot be measured.
39. Systematic errors appear in repetitive and fixed forms. Increasing the times of parallel determination and adopting the method of mathematical statistics can eliminate the system error to some extent. ?
40. The magnitude and positive and negative values of accidental errors are not fixed, but follow Poisson distribution, which is symmetrical, bounded, compensatory and unimodal.
The range of 4 1. is the difference between the maximum value in the measured value and the true value. The advantage of using it to express the accuracy of measured data is that the calculation is simple.
42. Truth value refers to the objective value or actual value of equivalent effect at a certain moment, a certain position and a certain situation, which is measurable.
43. If the first digit is greater than or equal to 8, one more digit can be recorded. ?
44. When using extended uncertainty, the expression should indicate the confidence probability and give the degree of freedom, so that the uncertainty can be extended to the next level.
45. The average value of more than four measured values can be increased by one bit than the significant figure of a single measured value in some cases. 46. Mixed operation of significant digits In order to prevent the rapid accumulation of errors, one significant digit can be reserved for the data involved in the operation and the intermediate operation result, and then the calculated result can be corrected to the number equivalent to the maximum error data. ?
47. The first digit of the logarithm in the significant number is the significant number, and the mantissa digits of the logarithm should be equal to the significant digits of each value. ?
48. When multiplying and dividing significant digits, the data with the smallest relative error among the data involved in the operation should be corrected before the operation. The significant number retained in each number should be the least significant number. ?
49. According to the distribution characteristics of system errors, it is inevitable that the measured values are discrete, and it is normal to have individual extreme values. 50. In Grabs t >, if t >; T critical value, otherwise discard the suspicious value, otherwise keep it.
5 1. When the error range is 2S, when the determination times are less than 6 times, suspicious values cannot be put forward.
52. Control charts can accumulate a large amount of data, thus obtaining more reliable internal boundaries.
