摘　　要：设计并研制了一种小样品快速冷却实验台的自动测控系统,该系统包括弹射触发控制单元、小样品沉浸速度测量单元及小样品在冷却过程中的温度测量单元,各测量单元在计算机的控制调度下同步进行.将该系统应用于生物小样品在过冷液氮快速冷却的试验研究,结果表明,测控系统测量误差小,控制精度和可靠性高,测量结果符合理论与试验要求.The development of an automatic testing and controlling experimental system for rapid quenching of a small sample is reported. The system contains the controlling unit of ejecting trigger, the speed measured unit and temperature measured unit of the small sample. These units go on at the same time under the computer controlling. As the equipment is used to study the ultra -rapid cooling of a small sample in sub -liquid nitrogen, it shows that the measurement error of the system controlling is small and the controlling is very reliable, and the test result agrees with the theory and the requirement of the experiment.
