稀疏

Certain changes in the gene may result in "male pattern baldness", marked by receding hairlines and thinning of hair at the back of the head.

Test analysis of sparse fall of water pressure In order to examine the water power relation situations of two levels, this ore carried on a experiment of closing the valve in -400m, after turned off the valve one day, the water level rose from -400m to -70m, accumulated water volume 240m3, also two hydraulic pressure rose, it explained that the two water entries had certain water power relation, it also accumulated that the hydrospace are not big.

测试分析稀疏秋天的水压力为了探讨水权关系的情况下两个层次，这个矿进行了一项实验，关闭阀门，在400米后，关掉阀门一天，水位上升至- 400米至70米，累积水量240立方米，还有两个水压上升，它解释说，这两个水作品，也有一定的水权关系，而且还积累了hydrospace并不大。

The spectrum analysis shows that ① Infrasonic waves produced by meteor are mostly very short, lasting one to five minutes;②Periods of the infrasonic waves range mostly from 40 to 408 seconds, and a few waves range from 40 to 480 seconds;③ During 7:21 p.m. to 8:41 p.m. on Nov. 17, the infrasonic waves were much denser. After 8:41 p.m., the waves become more and more sparse, all waves conform to those observed with naked eyes;④ Amplitudes of infrasonic waves from meteor differ significantly from each other (weaker ones below 5 to 10 Pa, medium ones from 10 to 20 Pa, and stronger ones from 20 to 40 Pa). Two of the strongest ones reach 75 Pa and 50 Pa respectively around 7:28 p.m. and 8:07 p.m. on Nov. 17. An explanation of above results is given.

频谱分析结果表明：①各流星产生的次声波大都很短暂，持续时间为1~5min；②流星次声波的周期大都在40~408s；③在1998年11月17日19：21-20：41期间流星次声波仍很密集，20：41后才变得越来越稀疏，恰与肉眼观测结果相符；④流星次声波的振幅彼此相差很大，较弱的在5~10Pa，中等的在10~20Pa，较强的在20~40Pa，最强的两个波在11月17日19：28和20：07前后分别达到75Pa和50Pa。

In this paper, the sparse approximation inverses and eigenvalue translation based preconditioners for Krylov subspace methods are thoroughly researched by situation of research at home and abroad, their internal mechanism are studied also.

本文在国内外关于Krylov子空间方法的稀疏近似逆和基于特征值转换的预处理方法研究状况的基础上，对它们进行了进一步研究，探讨了它们的内部机理。

In the sagittal plane of the model, contour density of the temperature distribution was more intensive near to the heater, while was more sparse far from the heater. Isograms were also irregular oval.

在模型矢状面上，距离热源越近，温度分布等值线越密集，越远越稀疏，亦呈不规则椭圆形分布。

Of course it is. What else could ..." This behind their hands; rustling of craned silk and satin behind jalousies closed upon the sun of Sunday afternoon as the thin, swift clop-clop-clop of the matched team passed:"Poor Emily.

当然，还有什么能……&这样的闲谈总在劳作之余，星期天的下午都被这种冠冕堂皇后面的嫉妒包围着，&可怜的Emily，&伴随着稀疏而短促的&clop-clop-clop的机器声传来传去。

The shockwave of the meteorite strike on the terrane of the surface passes the dynamic energy to the surface and forms the target terrane shatter cone; due to the fact that the terrane of stricken surface can not maintain the state of stress, a cluster of rarefaction wave was formed behind the shockwave to decompress terrane substances from high pressure state, this cluster of rarefaction wave ejects with high speed from the interface between the substances such as meteorite, surface terrane and lava, the shockwave compresses the target terrane substances, generating super-high temperature and forming a jet current of rock mass, rock powder, lava or rock fog with high pressure and temperature, the jet current lasted until the shockwave rebounded from the backside of rock, and the target of meteorite-stricken surface is formed on surface.

陨石撞击地面岩层时的冲击波把动能传给地表产生靶岩震裂锥，由于被撞击地表岩层不能维持应力状态，冲击波后面就发展一簇稀疏波使岩层物质从高压状态下减压，在陨石、地表岩层、熔岩等物质交界处高速喷出，冲击波压缩靶点岩层物质产生超高温，成为压力大温度高的岩块、岩粉、熔岩或岩雾喷射流，直到冲击波从岩石背侧反射、地面上形成陨击靶点。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
