在此基础上，详细研究了齿轮参数、轴承参数和结构参数对二平行转子—轴承系统和DH型透平压缩机的失稳转速、临界转速和不平衡响应的影响。

The static natural frequencies and dynamic frequencies (under 3000rpm) are calculated by the finite element method and cyclic symmetry technique. The rotating vibration behaviors of the two models are compared. Different vibration characteristics between the two models are discussed. Geometry mismatch in a turbine blade root, which arose in manufacturing process or caused by wearing out during service, leads to contact conditions changed in fir-tree attachments. As a result, shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade.

在叶片—轮盘耦合系统振动研究方面，建立了带围带的叶片振动计算模型和带围带的叶片—轮盘耦合系统振动计算模型，考虑旋转离心力作用，采用波传播技术，对两种模型分别进行了整圈模态分析，得到了某汽轮机叶片模型和叶片—轮盘耦合模型在0转速和工作转速(3000rpm)下的振动模态，并对所得结果进行分析比较，讨论了整圈叶片振动模态与叶片—轮盘耦合振动模态的区别。

In this paper, a performance index, which is used to evaluate the operating uniformity of multi-cyclinder engine, is presented based on the fact that the fluctuation of gas pressure in the expansion stroke cyclinder leads to the fluctuation of instantaneous angular velocity. The value IP is propotional to the fluctuation of instantaneous angular acceleration. Fuzzy diagnostic index for misfire fault is introduced and investigated also in this paper.

根据多缸发动机曲轴瞬时转速波动不均匀性主要由缸内循环气体压力波动不均匀性引起这一基本事实，以曲轴瞬时转速的实时检测为基础，在一个工作循环内按着火顺序将作功冲程中瞬时角加速度的波动作为评定各缸工作不均匀性的指标，将所得IP模糊化用于多缸机的故障诊断也作了初步的探讨。

4 Keyboard through the control of speed, and speed of digital tube display.

通过4*4键盘控制转速，并且在数码管上显示转速。

To discuss the effect of pin carding plate on fiber length distribution in the card slivers,length tests to the card slivers under different carding plate gauge,taker-in speed and doffer speed using pin carding plate and saw-tooth carding plate under the card taker-in by USTER AFIS single fiber tester were done.

为探讨梳针分梳板对生条中纤维长度的影响，用AFIS单纤维测试仪，对在梳棉机刺辊下分别加装梳针分梳板和锯齿分梳板时在不同分梳板隔距、刺辊转速、道夫转速条件下所加工的生条进行长度检测。

A person can place a drill in the drill chuck that is secured in the spindle of the drill press. They can then select the desired speed for rotation (commonly by switching belt pulleys), and activate the spindle. Then they manually pull on the quill lever to drive the drill into the workpiece being machined.

操作者可以将钻钻头装在钻夹中，钻夹固定在台钻的轴里；接着可以选择所需的转速（通常通过切换皮带改变主轴转速），并且启动主轴旋转，然后操作钻轴手柄，将钻头钻入被加工的工件。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
