two-phase three-wire system

Three sets of common silicon controlled single return circuit control system was replaced by an intelligent temperature control instrument which gives good solutions to temperature control hysteresis and disturbance between two sys-tems in the synthesis of O-cresol.

用一台智能控温仪代替三套常规可控硅单回路控制系统，解决了化工试验研究中大滞后系统的控温问题和系统之间的相互扰动问题。

In this system, effective temperature predicted from observation g-r color index and Ballmer ( Blamer) lines strength are introduced. Two theoretical and three empirical temperatures estimates are obtained finally. 5. Galactic Open and Globular Clusters are used for Validation of metal abundances.

在本系统中，我们还实现了通过观测的g-r色指数和通过巴尔默（Blamer）线系的强度预测得到有效温度，最终使用了两个理论的有效温度估计和三个经验有效温度估计。

It adopt numerical control system and linkage with three axes, two sides milling at same time with aplomb upright milling cutter at a batch plate tensile sample.

采用数控系统，通过三轴联动，在一个批量的板状试样上，用垂直立铣刀的方式，双面同时铣削。

An automatic system for the measurement of two-dimensional distribution of resistivity of semi-insulating gallium arsenide wafer with three electrode guard method is presented in this paper. In actual application, the fluctuation of temperature and abnormal data obtained would influence the results of the measurement seriously.

本文介绍了三电极保护法半绝缘砷化镓材料电阻率二维分布自动测量系统，在实际应用中，温度波动、异常数据对测量结果产生严重影响，为此我们提出了一些措施。
