当在—1型衍射仪上用国外标准法做定量分析时,仪器的测量误差对测量结果有极大的影响。该误差与连续记录待测样品和标准样品的衍射线强度的时间有关。为了减少仪器测量误差,需提高X光管的稳定性。这一点在技术上是困难的。为了提高相分析方法的速度,并尽量减少仪器的测量误差,制造了双管衍射仪。此仪器用闪烁计数器
When the -1 type diffractometer with quantitative analysis of foreign standards, the measurement error of the instrument has a great impact on the measurement results. This error is related to the time taken to continuously record the diffraction line intensities of the sample to be tested and the standard sample. In order to reduce the measurement error of the instrument, it is necessary to improve the stability of the X-ray tube. This is technically difficult. In order to improve the speed of the phase analysis method and to minimize the measurement error of the instrument, a dual-tube diffractometer was manufactured. This instrument uses a scintillation counter
