两对称

We also find that the coseismic displacement amplitudes are asymmetric across the seismic fault, with the displacements south of the fault about 10%～20% larger in amplitude than that north of the fault.

我们还发现形变沿断层两盘并不对称，断层南盘的位移比北盘大10%~20%。

We succeeded in synthesizing two different segments: C〓-C〓 and C〓-C〓, employing Sharpless dihydroxylation reaction, Julia coupling and samarium diiodide mediated reaction as the key steps.

我们从单保护的1，3-丙二醇出发，以Sharpless不对称双羟化反应，Julia偶联反应以及SmI〓参与的反应为关键步骤，经过艰苦的多条合成路线的尝试与探索，成功的得到了Phorboxazole A B的两个不同的边链部分C〓-C〓和C〓-C〓。

The simulation results show that the die swell rate of height direction is greater than that of width direction. Due to the difference of material characteristic of the two polymers, the end section shape of coextrusion is dissymmetric drum. The coextrusion interface would be change during the extrusion swell process.

有限元模拟结果显示：聚合物在离开方形口模后，熔体高度方向的挤出胀大率明显大于宽度方向的胀大率，且两种熔体的挤出胀大率不同，熔体术端截面形状为不对称的鼓形；在挤出胀大段，共挤出界面的形状和位置会发生变化。

Firstly, it introduced the import principium resolving thread and steps of analytic hierarchy process. Secondly, it erected model of population modernization, which based on the steps of analytic hierarchy process. Lastly, it got the maximal eigenvalue of dissymmetric matrix and corresponding eigenvector with SAS, and normalized the eigenvector to get weight value.

本章分为两部分，第一部介绍分析法的提出、原理以及解决问题的思路和步骤；第二部建立模型确定权重，根据层次分析法的原理和步骤，建立人口现代化指标体系的模型，运用SAS求解所构造的非对称判断矩阵的最大特征值，从而得出所对应的特征向量，变形后得到权重。

The control of system can be converted to the motion planning problem for a driftless system.

首先导出由两个对称刚体组成的力学模型的非完整姿态运动方程。

It consists of symmetric spherical roller,two pcs of prssed steel cages,flangeless inner ring and guide ring centred on the cage.In general,this kind of bearing has more roller quantities and higher dynamic load rating.

国际最新设计，对称滚子和两片钢冲压保持架组成内圈无挡边，没有中挡圈，调心滚子一般会增加2到4个，提高轴承的径向额定动载荷。

The addition reactions with phosphine anion andthe CsF promoted Strecker reactions were chose to evaluate the relationship of thesetwo chiral groups in the diastereoselective additions of the imino group.

通过亚磷酸负离子的加成反应和CsF促进下的Strecker反应研究了这两个手性基团的不对称诱导的匹配情况。

These two calibration methods were compared with numeric experiments. Results indicate that comparing with MSDM, BDM is not only available for the force calibration of non-spherical or anisotropic cells, but also for irregular cells in optical trap potential with inharmonic and asymmetric profiles. The results agree with the experiments reported.

用数字实验对这两种标定方法进行了比较，结果表明：与均方位移法相比，玻尔兹曼统计法不仅适用于各向异性非球性细胞，也适用于非简谐、非对称光势阱中任意形状的生物细胞光阱力的标定，结论与已有直接实验相符。

The clamp device comprises the grip part connected with the clamp part through the linking part, with the clamp part composed of concave part and the first and second arms extended to both sides, the first concave slot horizontally going through the first arm, the second concave slot horizontally through the second arm, a U shape tunnel parallel with the horizontal surface formed by two arms and with the concave part, cylinder hole set inside the top and down side all symmetrical inside the second deep slot, rotary shaft with both ends insertable to the cylinder hole, linking pole component fixed on the rotary shaft, limit component set on the first arm locking the linking pole.

本发明提供一种夹取装置，该装置包括：握持部，夹取部通过连接部与握持部连接；夹取部包括：凹形部，及由其两侧延伸的第一臂和第二臂，构成容置空间；第一凹槽，水平穿设于所述的第一臂，第二凹槽水平穿设于所述的第二臂，分别平行于凹形部及所述两个臂构成的平面，形成U形通道；圆柱形孔，对称设置于第二深槽的上下侧壁内；转动轴，两端可插入所述圆柱形孔中转动；连杆组件，固定于转动轴上；限位件，设置在第一臂上，用于锁定连杆。

The ocular accommodation has a great influence on refractive components. It is not only the process by which the refractive power of the lens is increased. But the lens itself moved forward relatively. The accumulation effects of accommodation induced by near-work is the main cause of myopia developed in children. The asymmetry of corneal surface was not only related to keratometer K1 and K2 , even the curvature within the same horizontal or vertical meridian was asymmetry.

调节本身不仅是传统意义上的睫状肌收缩和晶状体变凸，同时还伴有晶状体的相对前移；调节对眼的几乎所有屈光构成因素有着显著的影响，视近活动的累积效应是儿童近视眼发生的主要原因；角膜的非球面性不但表现为两个相互垂直子午线的曲率不等，即便是在同一垂直或水平径线上的屈光分布也是非对称的。

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％。
