查询词典 pitch ratio

Fine Pitch: Fine pitch is more commonly referred to surface-mount components with a lead pitch of 25 mils or less.

细间距：通常指引脚间距小于25密尔或以下的表面封装元件。

The microprocessor controlled pitch regulation ensures continuous and optimal adjustment of the angles of the blades in relation to the prevailing wind.The pitch mechanism is fitted in the blade hub and contains a separate hydraulic pitch cylinder for each blade. These separate cylinders also ensure triple braking safety, because one feathered blade is sufficient to stop the turbine.The adjustment procedure takes place every second.

基音修正是在HPEM的基础上进一步提高基音估计的精确度，其目的是提高高频谱的拟合程度。

The following three disadvantages of power spectrum reprocessing method for pitch detection are found: half pitch error and double pitch error with transition sound; easy distortion in noise speech; the complex method of judging voiceless and voiced speech.

本文分析了功率谱二次处理基音检测方法的不足：对于过渡语音，易产生半频或倍频误判；噪声干扰下，检测结果易失真；清、浊音的判断方法复杂。

And is improved; Water cooking method go on adherence test indicate to asphalt mixture, the viscosity rises to 4 or 5 from 3 or 4; The equivalent of changing the pitch of modified asphalt some, the needle enters one degree of findings in high- temperature performance , such as index ,etc., the high-temperature performance of changing the pitch of silicon is improved to some extent; Indicate that the mobility of the modified pitch is diminished in glueing the research of playing the index ; Oppose water damage research of ability indicate , resist water damage ability raise to some extent.

按标准对沥青混合料进行配级后，用马歇尔实验确定了12%由擦洗法提纯的露水河硅藻土改性沥青混合料的最佳沥青用量为4.5%，用硅藻土改性沥青改性效果较好，可用做公路沥青路面的改性材料。硅藻土改性剂与沥青在强制搅拌过程中，没有发生明显的化学变化，主要是物相之间的分散、均混、吸附和交联，所以主要是物理意义上的共容，因此是否共容，混匀至关重要，只有改性剂微粒能均匀稳定的分散在沥青中不发生分层、凝聚和离析，才能达到理想的改性效果。

With this method the pitch parameters can be determined easily and unfailingly by taking the pitch angle and pitch radius of the wheel and the spiral angl...

最后，给出了一个计算实例说明这种方法。

De la Mancha has released unstable , a VST effect plug-in for Windows that likes to mess around with your audio pitch, with 3 subtle pitch modulation modes to simulate the unpredictable but lovable pitch instability of an old tape machine or analogue equipment.

德-拉曼恰发布了不稳定的，一个的V ST效果插件在为窗口，喜欢乱七八糟靠近你的音频足球场， 3个微妙的沥青调制模式模拟难以预测，但可爱的间距不稳定的一个老磁带机或模拟设备。

The article analyzed the Franz Schubert's Piano Sonata, Op.120 all-around with the elements of multidimensional structures, such as the pitch, rhythm, and textures. It discussed the effect of change and ratio to the drive and structure of the music through the three aspects of combination: the synchronous change and symmetry ratio of the element rhythm, the asynchronies change and the asymmetry ratio of the element rhythm, and the synchronous with asynchronies changes, and compared them with the Heinrich Schenker system.

内容提要：本文以舒伯特《钢琴奏鸣曲OP.120》为例，对该部作品的音高、节奏、织体等多维音乐要素进行了综合分析，从要素节律的"同步变化"和要素节律间的"匀称比率"、要素节律的"异步变化"和要素节律间的"非匀称比率"以及要素节律的"同步变化"、"异步变化"的结合三方面，来探讨了这些"变化"、"比率"对音乐的动力、结构力的作用，并与申克的还原体系分析方法进行了比较。

D. When the ratio of louver pitch to fin pitch is LP/FP=1.25, the integral performance of the louvered fin radiator is favourable.

分析百叶窗间距和翅片间距的比值对气侧传热和流动性能的影响，当百叶窗角度为27°，LP/FP=1.25 时，具有较好的综合性能； e。

A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.

基于船舶操纵性分离建模理论，采用荷兰船模试验水池B系列螺旋桨的敞水试验结果，利用Akima插值获得了不同类型的调距桨在不同螺距比下的四象限推力系数和扭矩系数，求得调距桨的推力和扭矩，建立了调距桨船舶的平面运动数学模型。
