Finally, the four-unit cylindrically conformal microstrip antenna array is processed and tested. Testing results indicate that, the input VSWR of the antenna array in the vicinity of 1.575GHz is less than 2, the omni-directional performance good, 3dB bandwidth is about 90 degree on axial plane, right-hand circularly polarization good. Overall performance of the antenna array satisfies the design requirements.

The angular extent in a specified plane which contains all the radius vectors of the polar curve of luminous intensity having lengths greater than a specified fraction of the maximum.

在某一平面上，一定角宽范围内所包含的光强极轴曲线上的矢径长度均大于其最大值的某一特定比例，这种情况定义为光束的发散。

The measurement beam travel through the half circular polariscope and rotating analyzer to generate a measurement signal. As these two signals are guided into the lock-in amplifier, the phase retardation of the waveplate can be obtained.

由於锁相放大器所显示的相位延迟量在-180°~180°范围内，超出此范围则会产生误判，因此加入波长位移的技术，透过波长改变前后所产生的相位延迟量变化差值，可由此差值之正负号确定波板慢轴方向。

The rotor is then heated and press fit onto a cooled precision-machined one-piece stainless steel shaft and the assembly is then machined and balanced as a unit.

转子经过加热后压入配合进经过冷精密加工的一体式不锈钢轴内，然后机械和平衡设备装配成一个整体。

Interference fit: results in an interference between the two assembled parts--the shaft is larger than the hole, requiring a force or press fit, an effect similar to welding the two parts.

过度配合：在两个装配在一起的零件之间或者存在着过盈，或者存在着间隙的配合——轴可以小于或大于孔，但仍在规定的公差内。

With the deformation increasing, failure in the hollow specimen starts from the hole wall for the minor principal stress; and the bearing capacity drops off.

利用中晶和细晶两种人理岩的不同内径孔道大理岩试样，在内孔压力为0时进行常规三轴压缩试验，分析试样内非均匀应力分布对试样承载能力和变形特性的影响。

It is found that imaging by the system is nonlinear duing to SMF,illumination system and reception system both affect the sum optical signal intensity,and optical sectioning strength of the system is depended on prober and SFM.

根据透镜成像规律和单模光纤的传输特性，获得基于单模光纤的共聚焦内窥成像系统轴向光强分布，发现系统的成像过程由于单模光纤的介入呈现非线性，照明光路系统和接收光路系统仅影响系统接收信号的总强度，系统层析能力取决于探头和单模光纤性能。

When rotational axis are unknown, the general solution of camera intrinsic parameters is obtained by the eigenvectors of 2D projective transformation.

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％。
