查询词典 occlusion

With the object correspondence, the occlusion problem can be solved easily and the 3-D probability distribution of moving objects can also be estimated more precisely. These advantages make the results of objects tracking and correspondence more robust and reliable.

有了物体的对应关系，就可以解决物体交错所造成的追踪错误，并且能够更加正确的估测三维物体的机率分布，使多物体的追踪和对应更加准确而可靠。

The second pass draws a screen space polyon covering the complete viewport and performs the ambient occlusion computation.

第二个pass 画一个覆盖整个视口的屏幕空间多边形，并且执行环境遮挡计算。

Objective To investigate the expression of COX -2 and significance in rats after cerebral artery occlusion.

目的探讨实验性大鼠大脑中动脉梗死后脑组织环氧合酶-2（COX-2）的表达及其意义。

According to Crenshaw et al.[1], wide tourniquet cuffs are more effective at lower inflation pressures than are narrow ones. Pedowitz et al.[2] demonstrated that curved tourniquets on conical extremities require significantly lower arterial occlusion pressures than straight tourniquets Fig.

根据Crenshaw[1]等人的研究，充气压力较低时宽的止血带比窄的止血带更为有效：Pedowitz[2]等人证实采用弧形止血带对圆锥形的肢体部分加压时，使动脉闭塞所需的压力比使用直止血带(长方形，straight tourniquet)显著降低(图1—1)。

Based on the four-vessel occlusion models, neuron apoptosis in CA1 region of hippocampus was detected by cresyl violet staining, the phosphorylation of JNK and Bad (ser128) were detected by immunoblot...

以大鼠四动脉结扎脑缺血模型为基础，应用焦油紫染色法检测海马CA1区神经元凋亡，采用免疫印迹检测JNK和Bad(ser128)的磷酸化。

Basing on the four-vessel occlusion models,neuron apoptosis in CA1 region of hippocampus was detected by cresyl violet staining,the phosphorylation of Akt and Bad(ser136)were detected by immunoblotting.

以大鼠四肢动脉结扎脑缺血模型为基础，应用焦油紫染色法检测海马CA1区神经元凋亡，采用免疫印迹检测Akt和Bad(ser136)的磷酸化。

Methods Transient (15min) brain ischemia was induced by the four-vessel occlusion in Sprague Dawleyrats. The antisense oligodeoxynucleotides of Src and Fyn were used to suppress the expression of Src and Fyn by intracerebroventricular infusion once per day for 3 days before ischemia. After 5 days reperfusion, rats were perfusion-fixed with paraformaldehyde and cresyl violet staining were used to examine the survival of CA1 pyramidal cells of hippocampus.

采用Pulsinelli-Brierley 4动脉阻塞(4-VO)大鼠全脑缺血模型，缺血前连续3d脑室注射Src、Fyn反义寡核苷酸(antisense oligodeoxy-nucletides， AS ODNs)抑制Src、Fyn蛋白的表达后缺血，复灌5d，石蜡切片，焦油紫染色，图像分析测定单位面积内焦油紫染色细胞面积总和，与缺血组及错义寡核苷酸组(missense oligodeoxy-nucletides， MS ODNs)比较进行形态学分析。

Objective To investigate the value of DSA、CTA in diagnosis of lower extremity arterial stenosis or occlusion.

目的 探讨DSA、CTA在下肢动脉狭窄或闭塞的影像学价值。

The surgical principles and method were discussed through one typical case report. Results Good clinical results of dentel occlusion and facial framework were gained in all surgical patients with no severe complications.

结果 LeFort Ⅰ型截骨术治疗陈旧性面中部骨折均获得良好疗效，患者口腔咬合和面型恢复满意，无严重手术并发症。
