电离室

A gas-filled ionization chamber uses this principle.

充气电离室就是利用这一原理。

The telescope consists of ionization chamber and Si surface barrier detector.

该望远镜由气体电离室和Si面垒型探测器构成。

12 Nm was researched using double plate ionization chamber as absorption cell.

利用双收集板电离室作为吸收池研究了Ar在4。

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.

烟雾检测电路C的烟雾比较器比较电离室电压从整个VDD的电阻分压器产生一个电压。

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。

The system is composed of main body of the chamber, gas-filled and electronics system.

该谱仪系统由三部分组成，电离室主体、充气系统及电子学系统。

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。

Methods The calibrated LiF grain was enclosed with PVC tube and put into the esophagus near to targeted center, CT simulation and 3D-TPS design carried out and three-field radiation ,one anteriorly and two posteriorly, by 6-MV-X-ray of linear accelerator was done after confirmation by EPID.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
