The variation of pH and conductivity of various phosphate solution with the solution temperature were obtained based on the physical chemistry theory and ionization equilibrium theory in electrolytic solutions, and be testified experimentally under radiation of ultrasonic wave. The pH was a linear function with the reciprocal of thermodynamic temperature, and the conductivity was a linear function with the temperature in phosphate solution.

三、超声波对双水相系统组成物质、两相组成及溶质分配影响的研究根据物理化学原理和电解质溶液电离平衡理论分析推导和实验验证，揭示了超声波作用下不同组成磷酸盐溶液的pH值和电导率随溶液主体温度变化的规律：磷酸盐溶液的pH值与溶液主体绝对温度的倒数成线性关系，磷酸盐溶液的电导率与溶液主体温度成线性关系。

The principle and design idea of Pt resistance digital thermometer by means of unbalanced bridge are expounded.

阐述了用非平衡电桥设计组装铂电阻数字温度计的原理、设计思想，提出了非线性项的处理方法，介绍了利用电阻箱或QJ23电桥组装数字温度计的3种方法。

When the piston in the cylinder-side movement from left to right, the left cylinder cavity as a result of increasing the volume of the left cavity space constant pressure to reduce, when the space left inside the pressure chamber below the pump pressure containers, according to the principle of balance of gas pressure and was pumping the gas container valve 5 after smoke was continuously pumped into the left cavity, at this time is in the process of breathing.

当活塞在气缸内从左端向右端运动时，由于气缸的左腔体积不断增大，左腔空间的压强不断的降低，当左腔空间内的压强低于被抽容器内的压强，根据气体压强平衡的原理，被抽容器内的气体经过吸气阀5不断地被抽进左腔，此时正处于吸气过程。

The Model FBS-3A seismometer principle of operation, s-plane pole-zero plot and frequency characteristics are presented.

分析了FBS-3A型等宽频带力平衡地震计的基本原理、零极点的分布和频率特性。

And then this paper introduces the principle and method to tune PID parameter based on Fuzzy control, which suits to control the two-wheeled self-balancing robot.

介绍了用模糊控制进行PID参数整定的原理和方法，并用该方法实现对两轮自平衡机器人系统的控制。

The self-balancing characteristic of the prime mover is introduced.

描述了原动机的自平衡特性，介绍了以直流伺服驱动器为核心的原动机模拟系统的结构及工作原理。

Sex-linkage population Used the most information principle prove the follow result: the sum of female and male information entropy less than three times of population gene information entropy, it is equal when population is reach equilibrium, and achieve the largest, from disequilibrium state to equilibrium, the entropy is swing but increase.

群体遗传变异的信息学模型研究（4）性连锁群体用最大嫡原理证明了雌性群体与雄性群体的信息嫡的和小于3倍的群体基因信息嫡，当群体平衡时相等，且达到最大。
