It is an up-to-date intelligent measuring calibrator. The instrument has the preset unctions o scanning requency, mode, multipoint scanning, and power o protection. 该仪器为新一代智能化测校验设备,具有预置扫描速率、状态、多点、掉电保护等功能。
Generally, the collimation correction must be made on almost all the measured data of small-angle X-ray scatterings. This requires to first employ either theoretical calculation or experimental determination in obtaining the weighting unctions of the instrument. 通常X射线小角散射实验数据几乎都需进行准直校正,这要求事先用理论计算方法或实验测定方法得到仪器的权重函数。
This article analyses quantitatively the f unctions of the slit filter. 本文定量分析狭缝滤波器的作用。
