1、天銳升降貨梯http://m.jxpj.com.cn/等精度測(cè)量，即在測(cè)量過(guò)程中，決定測(cè)量精度的全部因素或條件不變。例如，由同一個(gè)人，用同一臺(tái)儀器，在同樣條件下，以同樣方法，同樣仔細(xì)地測(cè)量同一個(gè)量，求M量結(jié)果平均值時(shí)所依據(jù)的測(cè)量次數(shù)也相同，因而可以認(rèn)為每一測(cè)量結(jié)果的可靠性和精確程度都是相同的。在一般情況下，為了簡(jiǎn)化測(cè)量結(jié)果的處理，大都采用等精度測(cè)量。實(shí)際上，絕對(duì)的等精度測(cè)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://m.jxpj.com.cn/不等精度測(cè)量，即在測(cè)量過(guò)程中，決定測(cè)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(cè)童方法，不同的計(jì)量器具，在不同的條件下，由不同的人員對(duì)同一被測(cè)量進(jìn)行不同次數(shù)的測(cè)量。顯然，其測(cè)量結(jié)果的可靠性與精確程度各不相同。由于不等精度測(cè)量的數(shù)據(jù)處理比較麻煩，因此一般用于重要的科研實(shí)驗(yàn)中的高精度測(cè)量。另外當(dāng)測(cè)量的過(guò)程和時(shí)間很長(zhǎng)，測(cè)蚤條件變化較大時(shí)，也應(yīng)按不等精度測(cè)量對(duì)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.
