两对称

The non-continuously moving state lies on the vehicle's structural characteristic. This air-cushion vehicle has two platforms, which are connected by two hydraulic cylinders. When it moves, one platform is fixed on ground as the base platform, and takes the other one as moving platform, then the vehicle can go forward by alternate movement of these two platforms. So the push-pull air-cushion vehicle is a self-propelled vehicle.

它的非连续运动形态取决于其结构特点，该气垫车由两个对称的子平台组成，中间通过液压油缸相铰接，运动时总是固定其中一个平台作为基础平台，而将另一个平台作为运动平台，基础平台通过液压缸推出或拉进运动平台交替动作，实现运动，因此推拉式气垫车是一种自走式气垫车。

After hydrogenation of the double bond and the addition of alkyne to a carbonyl we introduced the N-hydroxy group by SN2 reaction.

不对称氢化和炔负离子对羰基的立体选择性加成构建了两个新的手性中心，之后用羟胺衍生物对羟基的SN2取代反应引入了羟胺片断。

For accelerating this problem's compute time in parallel computer, we use Saul'yev type asymmetric different scheme and classicality explicit-implicit type to get a new alternating group explicit method for solving diffusion equation.

为便于在并行计算机上计算以加快计算速度，现将第二类saul'yev非对称格式以及古典显、隐式相结合，构造了求解扩散方程的一类交替分组显格式，其基本结构为四点组，并针对内点为偶数的情况，在节点两端点处进行了处理，以提高精度。

The axial velocity and stagnation point offset of two opposed jets coming from two asymmetric nozzles oppositely located with large separation distance were studied by using hot-wire anemometry.

采用热线风速仪对大喷嘴间距下两不对称喷嘴形成的对置撞击流的轴线速度分布和驻点偏移规律进行了实验研究。

The angular velocity of the line of sight and the lead speed of the missile.

找出了引起不对称现象的两个主要原因——视线旋转角速度和导弹的前置速度。

We propose an outpatient procedure under local anesthesia for the correction of prominent ears. We fold the antihelix with an anterior scoring method via posterior approach. The cartilage is preserved to avoid a sharp antihelical fold, and the scar is concealed in the posterior auricular sulcus. All patients had satisfactory correction of the deformity and yet no significant complication.

我们经由耳朵后将对耳轮软骨前表面作一个网状的雕刻，然后将之向后翻转作为新的对耳轮，可以避免软骨切除后所产生不美观的转折，避免产生两耳不对称的情形，术后没有血肿或皮肤坏死的并发症，手术所产生的疤痕隐藏在耳朵后面，所有的病人对手术结果都很满意。

And, for those who like me have an antiquarian's interest in relating Marx's detour to

对那些和我一样，对马克思避开竞争性分析障碍有文献研究兴趣的人，我将表明在这两个二者选一的清算制度中存在一个完全可逆的对称："利润是剩余价值的源泉"和它反过来是形式上正确的；只有利润率R*为正在矩阵意义上，在a0
