稀疏

The pressure attenuation of stress wave and the effect of blasting load on ground concrete structure in soil and rock blasting were investigated using LS_DYNA procedure in the aspect of mechanical properties of soil and rock, location of the goal and the explosives, as well as the rarefaction waves of air etc.

利用LS_DYNA程序，从岩土本身的力学性能、目标与炸药的位置、空气稀疏波的影响等多个角度出发，研究了岩土爆破中应力波的压力衰减以及爆破对地表混凝土结构物的影响，得到了其中的规律，为建筑结构的防护提供了一些思路与依据。

Leblanc. Now, in order to form an idea of the scene which is to follow, let the reader picture to himself in his own mind, a cold night,the solitudes of the Salpetriere covered with snow and white as winding-sheets in the moonlight, the taper-like lights of the street lanterns which shone redly here and there along those tragic boulevards,and the long rows of black elms, not a passer-by for perhaps a quarter of a league around, the Gorbeau hovel, at its highest pitch of silence, of horror, and of darkness; in that building,in the midst of those solitudes, in the midst of that darkness,the vast Jondrette garret lighted by a single candle, and in that den two men seated at a table, M.

现在，为了对以后的情节能有一个概念，希望读者能从自己心中想象出一个严寒的夜晚，妇女救济院那一带荒凉地段全盖满了雪，在月光中，白得象一幅漫无边际的殓尸巾，稀疏的路灯把那些阴惨惨的大路和长列的黑榆树映成了红色，在周围四分之一法里以内，也许一个行人也没有，戈尔博老屋寂静、黑暗，可怕到了极点，在这老屋里，在这凄凉昏黑的环境中，唯有容德雷特的那间空阔屋子里点着一支蜡烛，两个男人在这穷窟里坐在一张桌子的两旁，白先生神色安详，容德雷特笑容可掬而险恶骇人，他的女人，那头母狼，待在一个屋角里。

If you have lost all of your hair due to chemotherapy or another illness, you no doubt want to regrow hair quickly.

首先你会发现一旦你的头发开始重新生长出来的，是它可以在稀疏的地方，它可能在纹理改变。

The FFT of Helmholtz equation on the regular domain is studied. And the multifrontal algorithm is used to solve the matrix equations in computational electromagnetics.Finally, the finite-difference approximate forms of Maxwell equations and the Despres transmission condition are discussed.

为了充分提高算法的计算效率，研究了规则区域上Helmholtz方程的FFT快速算法，以及有效地将多波前算法引入计算电磁学领域用于求解差分稀疏矩阵方程。

If the step of the linear system question is not very high, direct solving method is better; if coefficient matrix of the linear system question is not regular and large-sparse matrix , direct solving method does not settle the storage question.

而在求解线性方程组的许多实际问题中，尤其在偏微分方程的差分方法与有限元方法求解问题之中，方程具有重要的特征，一是多为大型稀疏矩阵；二是满足一些条件如对称正定、对角占优等，这使迭代法得到广泛的应用。
