激光粒度儀中全量程和分檔量程的區別
Laser particle size instrument the difference between the full range and step in
激光粒度儀的量程是指系統所能達到的最大上限和最小下限，分全程量程和分檔量程兩種形式。
Laser particle size instrument range of www.cnfyny.cn is refers to the system can achieve the maximum and minimum of lower limit, is divided into whole range and step.
全程量程是從上限到下限一次測量，這種設置的優點是操作簡便，重復性好，沒有歧義，是目前大多數國內外激光粒度儀制造商普遍采用的方式；分檔量程是在全量程中又分成若干段。
Full range from ceiling to floor measurement at a time, the advantage of this setup is simple operation, good repeatability, no ambiguity, is currently the most domestic and foreign manufacturers widely used laser granulometer way; Step range is in the full range and is divided into several sections.
它的優點是在探測器數量有限的情況下提高分辨率，缺點是容易產生歧義（同一個樣品在不同檔的測試結果不一致），調整過程容易產生誤差，是早期激光粒度儀采用的技術。
It is the advantage of a limited number of cases in the detector to improve resolution, defect is easy to produce ambiguity (the same samples do not match the test results in different files), the adjustment process prone to error, is an early technology laser granulometer.
