Methods Perfusion weighted imaging was performed in 45 cases of cerebral infarction. The sidetoside ratios of regional cerebral blood flow,regional cerebral blood volume and mean transit time were measured at duty lesion of ischemia. The hypoperfused cerebral areas and the stages of ischemia were defined as follows:compensation stage: rCBF was normal, rCBVwas increased, MTT was prolonged;decompensation stage: rCBF was slightly decreased, rCBV was normal or decreased, MTT was prolonged;preinfarction stage: rCBF and rCBV were decreased,MTT was prolonged.

利用磁共振灌注成像技术（perfusion weighted imaging，PWI）对45例缺血性脑血管病患者的责任病灶进行局部脑血流量，局部脑血容量，平均通过时间比值测定，确定低灌注脑区的影像学特点和缺血分期：代偿期（rCBF保持正常，rCBV升高，MTT延长）；失代偿期（rCBF轻度下降，rCBV正常或下降，MTT延长）；梗死前期：（rCBF下降，rCBV下降，MTT延长）。

Because the error of normal vector will affect Delaunay triangular technique and the form of global triangular meshes directly, it is a key step to ensure normal vector .

由于法矢的错误将直接影响Delaunay三角剖分的结果进而影响整体三角网格的形成，所以法矢的确定是生成局部逼近平面的关键步骤。

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.

另外，提出了轨廓分区法全面计算轮轨接触状态法，在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下，可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量，以此来判断轮轨的真实接触状态：正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮，并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力，从而使仿真结果更接近于车辆在实际线路上的运行状态。
