The formation of billet steel rocker was calculated theoretically and analyzed using the differential method of rolling pressure along width in rolling deformation zone according to the position of the billet steel skid mark,the asymmetrical distribution of the mark degree and the departure of rolled piece centerline from the centerline of rolling.

在轧制变形区应用轧制压力宽向微分法，从钢坯滑道黑印位置和黑印程度的非对称分布、轧件中心线偏离轧制中心线两方面对钢板镰刀弯的形成进行了理论计算和分析，提出了改进操作规程、提高推床适应能力、改进加热炉滑道、加强加热工艺技术管理以及实施热送热装提高热坯的供应能力等多项措施，以适应多倍尺轧制工艺的要求。

As a natural result, the mass matrix is a positive definite consistent and time-independent one, and the two time-dependent and nonsymmetric matrice, that is, the "gyroscopic damping" and "centrifugal stiffness" ones, don't exist in the equation.

在不附加任何&运动学&假设的情况下，作为自然的结果，方程的质量阵是正定、协调的常数阵；方程中不存在两类时变的非对称系数项，即所谓的&陀螺阻尼&项和&离心动刚度&项。

All metaphases showed three distinct green signals, which have the same size and intensity, corresponding to a normal chromosome 8 and two isochromosomes 8q, and five red signals, of which one was located on a normal chromosome 8 and the another two quite symmetrically on the both arms of each isochromosome 8q, respectively.

结果发现：所有中期分裂相均显示3个绿色荧光杂交信号和5个红色荧光杂交信号；2个绿色荧光杂交信号分别位于2条等臂8q染色体着丝粒处，信号大小和强度均与位于正常8号染色体着丝粒处的1个绿色荧光杂交信号相当；1个红色荧光杂交信号位于正常8号染色体长臂上，另外2个红色荧光杂交信号非常对称地位于每一条等臂8q染色体的两条长臂上。

Badged Chana, this pair are quite striking to look at -- the sedan has a hint of Volkswagen CC in the bodyside, while I like the SUV's cool asymmetric rear end -- but are little more than vaporware from a company that for now rebadges other manufacturers' cars.

车查，这两人是相当惊人的审视-轿车已暗示大众消委会在bodyside ，而我喜欢越野车的阴凉不对称尾部-但略多于vaporware一家公司，目前rebadges其他制造商的汽车。

There are four C-phycocyanin trimers in the asymmetric unit, which associate face-by-face to form two hexamers.

晶体不对称单位中共有四个C-藻蓝蛋白三聚体，它们面对面地紧密聚合成两个六聚体。

Neumann freely here waste of space, design of two symmetrical staircases each room, but only one completed.

诺伊曼在这里大手大脚地浪费空间，设计了两个互相对称的楼梯厅，但只有其中一个建成。

If we regard the calm, one-colored strokes which join the background within the eye shapes as a visual absence, then we could very easily respond with the same shapes.

此类作品组织的单独对称，看与被看两个方面都能够吸收视线，致使观看变成无视。

Investigated are the optimum design parameters of two sets of identical multiple tuned mass dampers for one-story asymmetric structures.

研究了用两组相同的MTMD控制单层非对称结构扭转振动的最优设计参数。

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％。
