According to Markovian theory and Langevin equation with random ambulate in concern simulated the excursion and diffusion of oil.

采用马尔科夫随机理论建立分析污染物粒子的运动过程，即通过Langevin方程追踪质点求得油膜的漂移扩散过程中考虑了油膜扩散随机数的影响。

First came their Oscar-nominated 2000 breakthrough,"Amores Perros"(roughly translated,"Love's a Bitch"), which traces the intertwined consequences of a Mexico City traffic accident.

他们首次突破性电影是在2000年被奥斯卡金像奖的＂Amores Perros＂（粗略翻译为：Love's a Bitch），该电影追踪了一次发生在墨西哥城的交通时候后产生交织的后果。

In theory, firstly, the numerical simulation methods, such as the boundary element method, the finite difference method and the finite element method, were utilized to calculate the distribution of electric field intensity and potential of the electron-gun system, the focusing system and the whole equipment, respectively. Then, the trajectories of the electron-beam were traced by using of the Runge-Kutta method and the Monte-Carlo method associatively. The point spread function was also calculated.

在理论分析中，先后采用边界元方法、差分方法、有限元方法等科学数值计算方法，编制程序，对X射线源的电子枪发射系统、聚焦系统以及发射系统与聚焦系统的组合系统等的电场分布进行了严格的计算，在准确求得各系统电场内各个剖分点的电场场强、偏导数等参量的基础上，采用蒙特-卡罗模拟方法和不等距龙格-库塔方法相结合，追踪由LaB_6单晶阴极表面发射出的大量电子束在电场内的运动轨迹，求出点扩展函数，并根据点扩展函数的优劣，反复调节、大量计算对比，挑选出X射线源最佳的电极结构及其组合。

The response patterns were analyzed and categorized. The prolonged asystole was searched. Follow up was made at the outpatient clinic or by phone during October 2004. Two hundred forty-two patients (40.1%) had positive response. 172 patients (71.1%) with the mixed type, 60 patients (24.8%) with the vasodepressive type and only 10 patients (4.1%) with the cardioinhibitory type.

反应的型态皆加以分析及归类并寻找有长的心跳停止者而於2004年十月於门诊或电话做追踪。242位病人(40.1%)为阳性反应，其中172位(71.1%)为混合型，60位(24.8%)为血压下降型，而仅有10位(4.1%)为心跳抑制型。
