对X光探测器X-ray CCD165-SX在帧移模式下进行数据采集。选择合适开口高度的掩膜，使得CCD的曝光面仅是整个探测面的一小部份。利用TTL信号发生器产生的脉冲信号触发子潜像帧移，将各个不同时间内产生的子潜像储存在CCD的芯片上不同位置上，当芯片填满子潜像时，一次性读出。这种方式大大加快了实验数据的采集速度。实验中对快速升温的情况下对PE样品进行测试，成功地采集到了随时间快速变化的散射信号。

By installation of the mask with adjustable opening size and TTL generator ,X-ray Scattering data is collected by X-ray CCD 165 SX under Frameshift mode .In the process ,exposure area is onlysmall part of the detecting area of the CCD and sub -images produced at difference times are frame shifted by TTL trigger to difference parts on CCD chip subsequently .All the sub-images are read out at once until the chip reaches full-ness of sub -images.This approach greatly increases the data collection speed .Finally,we use PE as the sam-ple in fast temperature rising environment for the fast data acquisition measurement and successful ly collected the scattering data which changed with times .
