Triggering off the free oscillation of the reinforced bar by amplifying the triggering signal of the piezoelectric ceramic sensor by the emitter coupled oscillation circuit , we have measured the oscillation frequency of various reinforced bars, and then we can calculate the magnitude of the corresponding pre stressing force accor.

论述了振动法测量钢筋的预应力的新方法，振动触及压电陶瓷传感器产生的电信号，通过双稳态触发振荡电路，经放大后启动钢筋自由振动。根据弦线振动频率和所受张力之间的关系，测量出不同型号不同长度的各类钢筋的频率，从而得出对应钢筋的预应

人们在法庭作证都是要手按《圣经》发誓的，中国古代诉讼前也有"盟诅"一说。

The persent study investigated how subjects of three different ages use covariation information and pre-existing belifs in causal reasoning.

本研究考察了小学、初中、高中三个年龄组的被试在使用经验信息和共变信息进行因果判断时所具有的不同特点。

The results were as follows:(1) The effect of covariation information is much bigger when subjects have no pre-existing beliefs about the problem.(2) Older subjects emhpasis covariation information more than younger subjects in their causal reasoning.(3) The effect of ΔP is not linear. Subjects change their judgements when it increases uo to some thresholds.

研究结果表明：(1)当经验信息无法证明待判断原因是否可信时，共变信息的作用要大一些；(2)随著被试年龄的增长，他们越来越多地采用共变信息进行判断；(3)ΔP值的作用并不是直线性的，只有当它增大到一定程度时，被试才会改变自己的判断。
