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）。

Hence, an analysis method of long-spread nonhyperbolic normal-moveout velocity for P-wave in weak transverse media with vertical symmetry axis is illustrated. The quartic term of the Taylor series expansion for t2-x2 curve is used to determine the normal-moveout velocity.

文中阐述了横向各向同性介质中长排列的非双曲线的P波时差速度分析方法，即对P波的旅行时间进行泰勒展开，应用t2～x2的四次方展开项进行时差速度分析。

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。

People in their daily lives the use of breathing, is a kind of instinctive, normal physiological movement, playing in the trombone breath used in almost all different from the normal breathing.

人们在日常生活中运用的呼吸，是一种本能的、正常的生理运动，而在长号演奏中所用的呼吸基本都不同于平常的呼吸。

If the normal-line indicator, turn off the printer, and then open, print a test page to see whether it is normal.

如果联机指示灯正常，关掉打印机，然后再打开，看打印测试页是否正常。

Originally, on wild Betta splendens the normal iridescent color is turquoise/green. This normal iridescence is limited to ray-like projections into the fins and several iridescent dots along the body of the fish.

起初，野生斗鱼的闪光色是蓝绿/绿色，这种一般的红彩专指鱼鳍上射线状色斑及沿著鱼身上的几个闪光斑点。

These offer either (1) a dis c o u n t to the normal selling price of a product, or (2) more of the product at the normal price.

上述提供或者折扣的正常售价产品(2)或更多的产品在正常价格。

The8 transgenic mice lactated naturally .and centrifuge to discard the fatness and the acid. At last ,we got the serum of the milk of 5 transgenic mice and 2 normal mice , checked the human insulin in serum by RlA.The result of the CPM show that two transgenic mice are conspicuous excess to the other transgenic mice and normal mice .and the mount of human insulin achieve respectively to 250uIU/ml ,376 ulU/ml.

转基因小鼠自然泌乳以后，收集到5只转基因小鼠和2只阴性小鼠的乳汁，脱脂脱酸以后，在乳清中用放射免疫检测方法检测胰岛素的表达量，结果其中两只转基因小鼠的表达量明显高于其它小鼠，表达量达到250uIU／ml和376uIU／ml，进一步的蛋白质定性和活性检测正在继续进行中。

The results prove that T*1 S-closed space and T2 S-closed space are identical and that the regular S-closed space and normal S-closed space are the same. Therefore, to make T*1 space X become the complete conditions of S-closed space is the X extremely unconnected H-closed space, while S-closed space X can be measured as the complete condition X of S-closed T1 normal (A1) space.

首先讨论了S-闭空间的分离性，证明T*1型的S-闭空间与T2型S-闭空间是相同的，正则的S-闭空间与正规的S-闭空间是相同的，从而得到要使T*1型空间X成为S-闭空间的充要条件是X为极不连通的H-闭空间， S-闭空间X可度量化的充要条件是X为S-闭的T1型正则(A1)空间。
