The effect of the number of jets and the pitch angle of jet on recovery coefficient of diffuser were analyzed, it is shown that the appropriate choice of parameters such as the number of jets and the pitch angle of jet can effectively control the flow separation in the diffuser.

文中还分析了不同射流孔数和射流倾斜角对于压力恢复系数的影响，发现选择合适的涡旋射流孔数及其射流倾斜角等参数，可以更有效的控制扩压器内流动分离。

In order to reduce the influence of scroll and pitch movements on the image quality of a TDICCD space camera,the requirements for the scopes of scroll angle and pitch angle and their control errors are put forward to obtain an image with high signal noise ratios and high resolution.

为了降低飞行器侧摆及前后摆对TDICCD空间相机成像质量的影响，提出了对飞行器侧摆角和前后摆角范围及控制误差的要求，以获取高信噪比和高分辨力图像。

According to the functional requirements of adaptive front-lighting system, the relationships between the yaw angle and pitch angle of light axis in AFS and vehicle parameters, including speed, steering wheel angle and pitch angle of vehicle body are derived, thus a kinematics model for AFS is set up.

根据自适应前照灯系统的功能要求，推导了车辆参数（车速、转向盘转角和车身仰俯角）与车灯光轴沿水平和垂直两个方向的偏转角度之间的关系，建立了自适应前照灯系统的运动学模型。

The analytical expresses of scattering field are obtained based on the boundary condition of a sheath helix model. The effects of the pitch angle and the electrical size of the helix on the resonant behavior are also investigated. It is shown that the resonant behavior of the forward/back scattering far field only depends on the pitch electrical size and the radial electrical size, and that the turn of the helix has no effect on the resonant behavior.

根据sheath螺线管模型的边界条件获得了散射场的解析表达，同时研究了螺线管在共振状态下电角度及螺间距的影响，表明远场的前后向散射的共振状态只依赖于间隙的电场大小及径向的电场大小，而螺线管的倒转不影响谐振状态。

Have absolute/perfect pitch,ie the ability to recognize or reproduce the pitch of a note

有绝对音高感(对一乐音音高的识别力或演唱、演奏的能力)。

In today's digital world, at least half of youngsters, who listen to music frequently, have absolute pitch because digital recordings are generally on pitch.

在这样一个数字化的世界中，至少一半的年轻人经常听音乐，由于数字录音中的音高一般是准确的，因而他们会具有绝对音感（尽管多数人不知道这一点）。

He said:" There has been a recent study on perfect pitch, the ability to know the absolute pitch of a musical note, that strongly suggests that is acquired through the inheritance of a single gene."

他认为：&近期进行了一项针对完美音高——指人能准确感觉每个音符的能力——的研究，它清楚地表明这一能力是由单个基因遗传下来的。&

" There has been a recent study on perfect pitch , the ability to know the absolute pitch of a musical note, that strongly suggests that is acquired through the inheritance of a single gene."

近期进行了一项针对完美音高——指人能准确感觉每个音符的能力——的研究，它清楚地表明这一能力是由单个基因遗传下来的。

There is some evidence that babies have the ability for absolute pitch, so researchers for this study theorize that maybe most lose this ability with age, but that what a so-called pitch gene does is extend this talent through a crucial period in childhood.

有证据显示，婴儿具有绝对音高，因此，研究者得出这样的理论——这种能力随着年龄的增长而消失，所谓的&音高基因&的作用就是使这种才能在经历童年的关键时期之后仍能幸存下来。

Anyone with absolute, or perfect, pitch are able to identify by ear any note at some standard pitch or to sing a specified note at will.

参考译文：任何一个有全阶音律的人都能够通过耳朵分别标准音高或者任意唱出特定音符。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
