    The current stablizer, reported in this paper, is part of a φ-ray spectrometer. Principally, it can also be used in other apparatus requiring stablized current. The stablizer can supply a maximum current of 100 A with a degree of stablity of 0.02% in ten minutes.

    论文中所叙述的磁场电流稳定器是β谱仪的一部分。基本上它也能应用在其他需要稳定电流的仪器上。它能控制的电流最大可到100安。稳定的程度是在10分钟内电流的变动不超过0.02%。稳定器采用负反馈伺服控制原理。首先将通过标准电阻的直流电流的误差讯号加以放大。为了避免直流电压放大器的漂移效应,我们桥式式平衡调制器将直流讯号变成交变讯号后再用交流放大,然后用相灵敏解调器恢复直流讯号。在这一过程中需要的增益大约是2×10~4,我们要考虑到调制器输出点在没有讯号输入时零电位的保持,调制器的载波成分输出问题,和经过放大后调制输出讯号的波形畸变。我们把放大后的讯号再加以功率放大来控制直流发电机的激励磁场,这样就能达到稳定电流的目的。因为在系统中存在着电容和电感,讯号在系统中傅递时就有时间延迟,在闭环系统就会产生低频振荡的不稳定现象。所以在系统中安装抵消这种振荡的镇定网络也是一种必要的措施。论文的最后部分描述稳定器的部件,具体的安排,运转结果和性能。

    In order to improve the carrier suppression factors Psup of the microwave ferrite modulator, the condition for maximum energy translation from the carrier to the sideband has been found through a mapping process by which a message space is mapped onto a signal space. The formulas of factors causing vestige carrier are obtained by specifying the translation condition for ferrite modulator and it is found that the theoretical value of Psup is in good agreement with that obtained.The modulation loss formula is also developed which shows that, in general,the less the parameters pertinent to modulator and driver, ρ1, ρ2, δ TU/T and △+,△- the less the modulation loss LM. In the ideal modulation where δ = 0, and ρ1 =ρ2 = 0, LM = 0.96db is found which is the same as the modulation loss value for any0-π modulator.
