Firstly, the three-dimension boundary question and its corresponding variation question concerning the point-source electrical field on a 3-D structure are presented. Secondly, the finite element method is used to solve the variational equation. The study area is divided into many tetrahedral elements. Then, we interpolate with a tri-linear function in each element. So, the variational equation is converted into a linear equation system. Finally, taking into account saving of time, we make use of symmetric successive overrelaxation preconditioned conjugate gradient algorithm to solve large linear system, and obtain the potential value of each node, resulting in the calculation of the apparent resistivity values on the ground surface.

In this study, symmetric successive overrelaxation preconditioned conjugate gradient algorithm is used to solve large linear system derived from 3-D finite-element resistivity forward modeling. Using row-indexed sparse storage mode to store coefficient matrix, the algorithm converges much quickly and requires much less storage of computer.

Result The spindles of oocytes were abnormal at 25℃ for 20 min, and disappeared at 25℃ for 30 min or at 4℃ for 10 min. 5, 10, 20 and 40 μg/ml Cytochalasin B for 2 h had no effects on the spindles of the oocytes. The spindles of oocytes were abnormal in 20 μmol/L colchicines for 1 h, and disappeared in 40 μmol/L colchicines for 1 h. The structure of spindles were perfect for 1-12 h when the oocytes were fixed in 4% paraformaldehyde.

Therefore, this approach is well suited for parallel computation on a parallel computer or system.

That exciting anger and nondescript hatred made him hammer that innocent clasp into pieces, only did such action make him feel relaxed for his intense and paranoiac mind.

内心激荡的愤怒和莫名的仇恨促使他用锤子把那只无辜的扣子砸的粉碎，唯有此才能使他那无比偏执又紧张的心松弛下来。

Tentatively at first but with greater radicalism in the 1990s, the party dismantled most of the monolithic Maoist edifice―parcelling out collective farmland, sucking in vast amounts of foreign investment and allowing private enterprise to thrive.

改革在90年代初期初次试水，共产党松弛毛泽东时代大部分的基石-开展集体承包制、大量吸收外国投资并允许私人企业蓬勃发展。
