粘性

Any of various viscous substances that are exude d by certain plants and trees and dry into water - soluble,noncrystalline,brittle solids.

树胶某些植物和树木分泌出的一种粘性物质，干燥后成为溶于水的非晶体、易碎的固体

The ratio of the magnitude of an applied shear stress to the velocity gradient that it produces; that is, a measure of a noncrystalline material's resistance to permanent deformation.

剪切应力数值与其产生应变速率的比值叫粘性，用来衡量非晶材料抵抗永久变形的能力。

Three different numerical iterative algorithms are developed and the accuracy and stabilities of them are compared. Tension and compression instabilities are studied and effects of Conservative Smoothing Approach and artificial viscosity on stabilities are discussed. Based on Taylor series expansion, Modified SPH method is proposed. The discrete forms of the function and its first derivative estimations of the kernel function are deduced in both one and two dimensional space.

Use pattern of Gao-Yong compressible onflow, 2 dimension of numeric imitate RAE2822 wing section differs in two kinds will shed what the circumstance falls to cross velocity of sound agglutinant circle sort a problem.

梗概： 应用Gao-Yong可压缩湍流模式，数值模拟RAE2822二维翼型在两种不同来流情况下的跨音速粘性绕流新问题。

In the meantime, mutual to shock wave of wing section surface and attrib border layer interference and turn turn problem undertakes analytic computation, the result makes clear, the numeric method with proper union of mode of Gao-Yong compressible onflow can succeed ground imitate wing section steps sonic and agglutinant flow.

Finally, we conclude that the value function of optimal switching control problem is a viscosity solution to this type QVI under some additional assumptions.

在这一章的最后在对值函数附加了一定的假设条件后还进一步地得到了最优切换控制问题的值函数是这类拟变分不等式粘性解的结论。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
