Results:① large dose of piracetam(≧600mg/kg) significantly increased scores of praxiology(p.01)、decreased water content(p.05) and the expression of aquaporin( aqp4) in mcao.②all dose of piracetam decreased volume of ischemic (p.01) and remained relatively intact ultramicrostructure.

结果：吡拉西坦注射液剂量依赖性地降低侧大脑半球的含水量、改善其神经功能评分、下调水通道蛋白4(aop4)的表达、降低动物的脑梗死体积、改善缺血脑组织神经元细胞的超微结构。

The quadrifilar helix antenna is widely used in the space communication, as it has globe symmetry band and good circular polarization.

四臂螺旋天线由于其优良的圆对称半球波束特性，良好的广角极化特性，在空间通信中得到广泛的应用。

The calculated regurgitant flow rates by using the hemispheric flow convergence equation were compared with actual regurgitant flow rates.

用半球血流会聚公式计算血流会聚返流量，与实际返流量进行比较。

Flow convergence regurgitant volumes and fractions were calculated by using the hemispherical flow convergence equation with 81, 71, 58, 46, 37 and 29cm/sec aliasing limit velocities, and the effective regurgitant areas were calculated with 58, 46 and 37cm/sec aliasing velocities.

按半球血流会聚公式分别计算混叠极限为81、71、58、46、37和29cm/sec时返流量、返流分数(返流量/二尖瓣口流入量)及混叠极限为58、46和37cm/sec时有效返流口面积(返流量/返流速度时间积分)。

NO is involved in the regulation of DA release from striatum during cerebral ischemia.

NO参与了缺血时纹体DA释放的调节。L-NNA抑制半球缺血时DA的不正常释放可能是其保护缺血大脑的机制之一。

Methods: The CCK 8 release from striatum were determined by microdialysis and RIA methods.

用微透析和RIA法测定半球缺血时纹体CCK－8的释放。

The spacial-temporal characteristics of the climate response to volcanos connect with the latitude location, season and strongness of volcanic eruption, Series analyses also confirm the obvious correspondence between the volcanic eruption and the climate change.

时序叠加研究表明，强火山喷发可造成半球和全球年平均温度下降约0.3℃，持续时间约两年；火山活动对气候影响的时空分布特征和火山活动特征：如火山喷发强度、喷发位置和季节等等有关。

Second, the left supramarginal gyrus (BA 40) was associated with reduced neural activity for phonologically-identical pairs with regular spelling to sound correspondences, when the mapping between orthography and phonology is made easy.

第二，当英文字对包含规则字时，由於字形与字音的转换容易，在左脑半球的顶叶下区(BA 40)产生大脑神经活动减少的现象。

A craniotomy with the size of 4 cm × 5 cm was placed at the site which corresponds to the sylvian fissure, the circular sulcus was exposed allowing transcortial exposure of the entire ventricular system, thus achieving the functional hemispherectomy.

手术均采用侧裂表面4 cm × 5 cm骨窗开颅，分开侧裂后经皮质进入侧脑室，完成功能性大脑半球切除手术。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
