Inhomogeneities in heavily Te-doped and boat-grown GaAs crystals (n>1x10~(18) cm~(-3) have been investigated by metallurgical microscope, X-ray anomalous transmission, X-ray reflection and infrared microscope technique. Impurity precipitates and inclusion in heavily Te-doped GaAs crystal are observed. Impurity segregative striation are observed by X-ray anomalous transmission. Formation of these defectes relats to level of heavily Te-doped and pulling technique during crystal growth.

The Wang Gong Chang Gun-powder plant explosion was a strange catastrophic event in the late Ming Dynasty.In this paper, the author make full use of the results obtained from two-dimensional finite element method of seismic response analysis and supersonic seismic modelling in recent years,and put foward a proposal that the reflection of vibrating wave ray due to buried bedrock topography underloose overlying soil layers may be one of the causes of the enlarged disaster. Whether natrual earthquake or man-made explosion, both of them can make convergence of the vibrating wave ray,and strengthen the vibrating energy, making the hazard more serious, because the Wang Gong Chang Gun powder Plant was just situated above the centre of the concave bedrock surface of Beijing Depression This is a new problem in urban disaster geology. In the conclusion, some concrete suggestions were advanced in unfolding disaster geological reseach as well.

明末北京王恭厂药局爆炸是一次奇案,本文利用作者近几年所进行的二维有限元地震反应分析及超声地震模型实验所获成果提出:松散复盖层下埋藏基岩地形对振波射线的反射可能是此次灾情被扩大的原因之一,不论是天然地震或人为爆炸,由于王恭厂恰处于北京凹陷埋藏基岩凹曲面中心,振波射线的汇聚使振动能量局部集中,从而扩大和加重了灾害,这是一项城市灾害地质学的新课题。文中还提出了开展灾害地质学研究的具体倡议。

The stability of the slow mode shocks perturbed by the one-dimensional, small-amplitude Alfvèn waves has been analysed under the condition of coplane among the obliquely incident wave vector, the background magnetic field and the normal of slow mode shock. The reflection and refraction of the Alfvèn waves have been derived on the plannar slow mode shock in general and calculated numerically on the coronal slow shock. It is shown that the slow mode shocks under the condition mentioned above are stable unless...

The stability of the slow mode shocks perturbed by the one-dimensional, small-amplitude Alfvèn waves has been analysed under the condition of coplane among the obliquely incident wave vector, the background magnetic field and the normal of slow mode shock. The reflection and refraction of the Alfvèn waves have been derived on the plannar slow mode shock in general and calculated numerically on the coronal slow shock. It is shown that the slow mode shocks under the condition mentioned above are stable unless the normal flow velocity upstream approaches the normal Alfven velocity upstream, and that the energy flux density of the Alfvèn waves propagating toward the interplanetary space increases when the coronal slow shock exists.

本文分析了斜入射波矢与背景磁场和激波法线共面时,一维小幅度Alfvèn波干扰下,慢激波的稳定性问题;论证了Alfvèn波在慢激波上的射线反射和折射规律;并就日冕慢激波情形进行了具体的数值计算。结果表明,除非上游法向流速接近上游法向Alfvèn波波速,在上述斜入射的Alfvèn波干扰下,慢激波总是稳定的。日冕慢激波是这种稳定性的一个例子;日冕慢激波的存在,能使起源于日冕向行星际空间传播(不管它起源于日冕慢激波之内或外)的Alfvèn波的法向能流密度增大。
