查询词典 dynamical friction

Induced drag occurs when the air flow separates from the surface of a wing, while friction drag is due to the friction between the air and bird moving through the air.

诱导拖动发生时，气流分离，从表面的一翼，而摩擦拖曳是由于摩擦之间的空气和鸟移动通过空气。

The results shoW that,both Si02 and mullite can be as friction additive,the friction coefficient and wear rate of counterpart incr......

在摩擦组元含量相同的情况下，添加莫来石的摩擦材料的摩擦系数、磨损量、对偶件的磨损量均比添加SiO2者要高。

Laser-textured specimens exhibited lower and stable friction coefficient as compared with untextured specimens under dry friction. The textured surfaces also exhibited lower wear rate than that of untextured specimens. It was found that micro-dimples acted as traps for wear debris, and hence decreased abrasive wear.

在相同试验条件下与未织构面对比，织构面的摩擦系数均有不同程度减小且表现得更为稳定，并且磨损率也得到一定的降低，这是由于所制备的表面微坑起到了捕获磨屑的作用。

However, there is no any kind of so-called absolute dynamical standard existing in music performance, the strong or weak music is a dialectical relationship, and is filled with multiple significance of relative performance factors.

但是，在音乐表现中并不存在任何一种所谓绝对意义上的力度的标准，音乐中的强弱是一对充满了辩证关系，并且具有多重意义上的相对性的表现因素。

On the other hand, AG is a new kind of dynamical systems approach.

仿射梯度方法是一种新的动力系统方法。

Excessive aggradation of extracellular matrix in the liver is the pathologic characteristic of hepatic fibrosis.The development of liver fibrosis is a dynamical process which is mainly due to the activation of the hepatic stellate cells, including not only excessive synthesis of ECM, but also its deficient degradation.

肝纤维化以细胞外基质在肝脏弥漫性过度沉积为病理特征，其形成主要由于肝星状细胞活化，ECM过度生成，降解相对不足，在肝内大量沉积所致。

For macro-observer, the actual effect of the high precision dynamic 3D image maps is equal to take the plane in certain height to observe along the selected air lane; for image interpreters, the maps offer the true, objective, continuous ground-sight images that can be repeatedly used for macroscopic analysis. The method of "RS geo-interpretational 3D visualizing and dynamical analysis to image" exploits new working ideas for regional geo-survey in altiplano, and it is great significance and practical value to improve modern degree of digital regional geo-survey.
