disturbing force

I find this Scythe of the Celt to be quite a disturbing force.

我发现凯尔特人的这把大镰刀相当是干扰的力量。

Finally the influence of different disturbing force model is detailed.

最后计算和比较了不同的摄动力模型选择对定轨精度的影响.

Furthermore, a mathematical method calculating the aerodynamic disturbing force of transverse jet stream is presented.

给出了计算横向喷流气动干扰力的数学方法。

The angular frequency of the disturbing force called the impressed frequency.

扰动力的角频率称为外加频率.

The disturbing force in the second standard of 2 state standard systems is more rational;

2套国家标准体系中第2套标准扰力更合理；

Dynamic tests mainly test the characteristics such as natural frequency, vibration mode and damping ratio, and also test the influence to the frequency of bridge when model car on different positions and the response of vehicle-bridge coupling vibration system under positioning disturbing force.

动力测试主要测试模型桥的自振频率、振型、阻尼比等动力特性，并测试模型车静止于模型桥的不同位置对桥梁频率的影响以及定位激扰力作用下车桥耦合振动系统的响应。
