查询词典 pitch-blackness

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。

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.

为了能够在较小的计算区域内不改变叶型而真实地反映出任意栅距比时的内部非定常流场，并避免近似仍采用相位后滞周期性条件，结合本文发展的网格技术，给出了一种新的实施方法，首次将动、静叶片数不等的离心式/轴流式叶轮机械转子、静子计算区域组合在一套结构化计算网格中，动/静叶排间的滑移界面完全按内场处理，避免了每一时层内，滑移界面处边界条件的迭代计算；并保证了每一时层，滑移界面处流动参数的守恒特性。

Some people have relevant pitch; perfect pitch is rare even among musicians.

有的人拥有类似的音质；完美的音质即使是音乐家也很少有的。

The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy.

探测器阵列(1)的间距小于入射强度辐射图的节距、使得后者被过抽样，由此得到高精度。

Pitch frequency by the sound level of the object decision, high frequency sound on the high, low frequency sound is low, the existing international standard pitch was in May 1939 in London by the International Standards Association of a1 = 440 Hz.

音高是由发音物体振动频率的高低决定的，频率高声音就高，频率低声音就低，现行的国际标准音高为1939年5月国际标准协会在伦敦通过的a1＝440赫兹。
