For the current in the ionization chamber is not amplified, so it is hard to collect the electric signal, in this paper, a direct I/F convertor is used to convert the electric current signal into frequent signal.

由于电离室本身不对电流放大，因此信号的采集较为困难，本文另外介绍了用I/F直接变换的电路以达到信号的转换。

Smoke Detection Circuit C The smoke comparator compares the ionization chamber voltage to a voltage derived from a resistor divider across VDD.

The position of radioactive source in the chamber has no remarkable influence on the measurement.

结果表明，当电极板间距离小于两倍α粒子飞行距离时，测量结果随电极板距离的增大而微弱增大，电离室中放射源的位置对测量结果影响不显著。

In order to make the uncertainty of the dose index measurement in the head phantom reasonable for the medical diagnostic X-ray radiation sources of the computed tomography, the measurement uncertainty components were analyzed according to the mathematical model for the computed tomography dose index test method with a 100 mm ionization chamber.

摘 要：为了使医用诊断计算机断层摄影装置X射线辐射源在模体中的剂量指数测量结果的不确定度评定合理，基于用带有100 mm长杆电离室的积分剂量仪测量CT剂量指数的数学模型，对其测量不确定度来源进行分析，列出了方差、灵敏系数及标准不确定度的计算公式，从而给出了CT剂量指数测量的合成标准不确定度和扩展不确定度。
