The determination of speed ratio gear box, it is necessary to take into account the different speed pump to meet the test requirements, but also consider the maximum torque of the engine near the work.

齿轮箱速比的确定，既要考虑满足不同转速泵的试验要求，又要考虑让发动机在最大扭矩点附近工作。

When spiral winding along geodesics finishs one winding cycle, the winding velocity ratio should be adjust to make the locator of fabric not to superpose the origination, and the amount of adjustment of winding velocity ratio should be determined by filling linetype of toroidal vessels big-radius or mid-radius or small-radius.

进行螺旋缠绕时，当完成一个缠绕循环后，为了使落纱点不致于又回到起始位置，应当对缠绕速比进行微调，微调量根据布满环形容器大径或中径或小径而确定。

During a low speed, the pitch angle is a constant, wind turbines keep on the optimum speed ratio between the pitch and wind so as to absorb the maximum energy.

该风力机在低风速时桨距角不变，保持最佳叶尖速比以获得最大风能；在高风速时储存或释放部分能量，桨距角仅完成限制最大输出功率，减少机械应力，风能储存在风力机机械惯性中，减少力矩冲击。

The experiment result show that the designed parallel algorithm has high speedup on NOW.

Experiments prove that this model can get higher linear speedup.

实验证明，这种并行模型能够得到较高的线性加速比。

Through the performance analysis and experiment, it can be easily concluded that this parallel algorithm works well and has speedup performance.

理论分析和实验表明算法是有效的，具有良好的加速比。

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。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
