在利用单摆测重力加速度实验中，有复摆、空气浮力、空气阻力、摆角等多种误差因素。
In the experiment of measuring gravity acceleration with a pendulum, a few error factors are existed, such as complex pendulum, air buoyancy, air resistance and initial displacement.
另外，我们也采用马力测试机、标准扭力分析多功能测试机、震动测测试机、分贝器、红外线转速测试机、偏摆测试机等等检验设备，来为产品的质量做最严格的把关。
In addition to these tests, we also use a Run out Tester, Digital Measuring Projector, Environmental Test Chamber, Orbital Tester , Infrared Tachometer, Vibration Tester, Decibel Level Detector…etc.
研究了摆辗成形规律，采用电测法和光塑性法证实了所选用的摆辗工艺参数合理，为推广该工艺提供了技术准备。
The authors have studied many deformation regimes of rocking forming. Using resistance strain gages and photoplasticity methods, it is proved that the parameters selected for the rocking forging…
