The present elastic-plastic model considers the summits of asperities with different radius and interaction between neighboring asperities when there is enough deformation for an asperity, so it is more practical than previous models, and is also a guide for further research of tribology models related to fractal characteristics.

建立的模型考虑各个微凸体具有不同的峰顶曲率半径，当变形足够大时考虑微凸体间的相互作用，因而较前人建立的模型更符合工程实际，同时也对与分形特征相关的摩擦学模型的进一步研究具有一定的指导作用。

Real contact between two surfaces occurs only at the asperities, which resulted in the fact that the asperities in real contact carry high load and are prone to elasto-plastic deformation.

摩擦副接触表面的接触只发生在极少数微凸体上，导致这些微凸体承受了较大的载荷，极易产生弹塑性变形。

The research results showed that there were no big difference in time of beginning fertilization between autotetraploid and diploid rice.

研究结果表明，同源四倍体水稻和二倍体水稻在发生受精作用的时间上没有存在着很大的差异。

The research results showed that there were no big difference in the time of beginning fertilization between autotetraploid and diploid rice.

研究结果表明，同源四倍体水稻和二倍体水稻在发生受精作用的时间上不存在很大的差异。

However, use bold, italic and larger font sizes within reason because otherwise you might achieve just the opposite effect.

然而，使用粗体，斜体和更大的字体大小的原因，因为否则可能会实现正好相反的效果。

The effects of the interfacial bond strength,the embedded length of fiber and the thermal expansion coefficient on the fiber pullout process were studied.The results showed that the model ...

结果表明该模型能很好的解释纤维拔出的破坏过程，纤维的最大拔出力和材料的承载能力都随面结合强度、纤维的埋入长度和基体的热膨胀系数增大而增大；纤维与基体热膨胀系数的不匹配对摩擦拔出力有直接影响。

However, we found that for loose sands, the dry bulk modulus seems to be greater than the shear modulus, especially at low pressures.

但是我们发现，尤其在低压条件下，疏松砂体中的干燥体变模量似乎比剪切模量大得更多。

Objective: To purify caffeic acid tetramer with macroporous resin on the basis of its fundamental physicochemical stability research.

中文摘要：目的：初步研究咖啡酸四聚体的理化稳定性的基础上选择合适的大孔吸附树脂，去除杂质，提高紫草水溶性部分中有效成分咖啡酸四聚体的含量。

Collared device for reducing stress shielding of calcar should be recommended for osteoporosis patients.

因此，骨质正常者应该选用非骨水泥假体，以减少大转子与股骨矩区域的应力遮挡；而骨质疏松者最好选用有肩托的假体，以减少股骨矩处的应力遮挡作用。

While a prosthesis that is too large can cause problems, lucencies around the stem of the intentionally loose prosthesis and most changes in the capitellum do not appear to cause problems, at least in the short term.

假体过大可能导致一些问题，但至少在短期内，假体周围透亮影和多数肱骨小头的变化不会导致其他问题。

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％。
