查询词典 spherical angle

In imaging electron optics, for a concentric spherical system composed of two spherical electrodes with electrostatic focusing, the electrostatic potential distribution and the spatial-temporal trajectory of electron motion can be expressed by analytical forms. It is naturally to take such system as an ideal model to investigate the imaging properties, as well as the spatial-temporal aberrations, to analyze its particularity and to find the clue of universalities and regularities.

在成像电子光学中，由两个球面电极组成的静电聚焦同心球系统，由于其静电电位分布和电子运动的空间和时间轨迹能以解析形式表示，很自然被采用作为理想模型，研究其成像特性和空间―时间像差，分析系统的特殊性，从而寻找具有普遍意义和规律性的线索。

The impoved design of the D35 trailor-form is rational, since the wagon ear is connected with the heavy load by hingel joint instead of spherical articulate, and the lateral relative displacement of safety pins is very small due to the rolling stiffness of schnabel grider, so that the friction stability of spherical-surface sockets of press-down cylinders is guaranteed.

新型D35联挂改进设计是合理的，因为车耳球铰改为车耳铰销联结后，利用钳夹梁的侧扭刚度来减小安全销相对横向位移，进而保障压柱油缸球面座的摩擦稳定性。

The digital simulation of thedynamic processes under step load input and supply oil pressure fluctuation were carried on by MATLAB. Analysis of the dynamic characteristics was done with the changes of the supply pressure, load, structural parameters of spherical hydrostatic bearing and the effective bulk modulus of oil. The conclusions show that structural parameters of the spherical bearing and the effect bulk modulus of oil have significant influence to dynamic characteristics, but the elasticity deformation of interior supporting collet has very small influences on the output response characteristics of the suspension system. The collets deformation can be neglected on the project.

在此基础上，建立了考虑内支撑筒的弹性变形与否时悬浮系统的数学模型，同时，建立了线性化的仿真模型，利用MATLAB对阶跃负载输入和油源压力脉动输入下的系统进行动态过程的数值仿真，结果表明球面副的结构参数，油液的有效体积弹性模数对系统的响应特性有明显的影响，而内支撑筒的弹性变形对悬浮系统的响应特性的影响很小，在工程上可以忽略其弹性变形。

Then, we employed the spherical-harmonic method to turn the classical transport equation for gluons into an infinite set of spherical-harmonic equations.

通过比较胶子和夸克的经典输运方程以及比较胶子的量子和经典输运方程，我们检验了新建立的胶子经典输运方程，证明它的确反映了胶子输运的主要性质。

Most respondents believe that spherical shade, column or cone lamp stand and elliptical lamp socket are better pattern elements matching the encouragement image. The highest mean of the matched pattern combination is "spherical x column x elliptical shape".

多数受测者认为具「鼓舞」造形意象的形态元素组合为，灯罩为圆球、灯柱为长柱状或是椎柱状、灯座为扁圆状较佳，其符合形态组合平均数最高为〝球状x长柱状x扁原状〞。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
