1、天銳升降貨梯http://www.jxpj.com.cn/等精度測量，即在測量過程中，決定測量精度的全部因素或條件不變。例如，由同一個人，用同一臺儀器，在同樣條件下，以同樣方法，同樣仔細地測量同一個量，求M量結果平均值時所依據的測量次數也相同，因而可以認為每一測量結果的可靠性和精確程度都是相同的。在一般情況下，為了簡化測量結果的處理，大都采用等精度測量。實際上，絕對的等精度測量是做不到的。
Tianrui cargo lifter such as precision measurement, namely in the measurement process, determine all factors or conditions constant measurement accuracy. E.g., by the same person, with the same instrument under the same conditions and with the same method, the same with a carefully measured quantity, the amount of M seeking results are based on average number of measurements are the same, it is possible that the results of each measurement the reliability and accuracy of the same. In general, in order to simplify the processing of measurement results, mostly using Precision Measurement. In fact, the absolute accuracy of measurement is impossible and so on.
2、天銳升降貨梯http://www.jxpj.com.cn/不等精度測量，即在測量過程中，決定測量精度的全部因素或條件可能完全改變或部分改變。例如，用不同的測童方法，不同的計量器具，在不同的條件下，由不同的人員對同一被測量進行不同次數的測量。顯然，其測量結果的可靠性與精確程度各不相同。由于不等精度測量的數據處理比較麻煩，因此一般用于重要的科研實驗中的高精度測量。另外當測量的過程和時間很長，測蚤條件變化較大時，也應按不等精度測量對待。
Tianrui cargo lifter range precision measurement, namely in the measurement process, determine all factors or conditions may completely change the measurement accuracy or partially changed. For example, children with different measurement methods, different measuring instruments under different conditions, by different individuals of the same is measured differently number of measurements. Obviously, the measurement reliability and accuracy of the results vary. Since the accuracy of the measurement data processing ranging from too much trouble, it is generally used for important scientific experiments in high-precision measurements. In addition, when the measurement process and time is very long, measuring flea condition change is large, ranging from precision measurements should also be treated.
