Based on the item of national high technology development project, the thesis studies the reasonable construction pattern of the tunnel portal, incidence of the micro-pressure wave and the the effect of bell-mouthed hood, lacunaris hood and expansile hood on alleviating the micro-pressure wave in the situations of single line and double line, obtains the relationship between the max micro-pressure wave and the velocity of the train as well as the relationship between the max micro-pressure wave and distance of measuring point at the velocity of 100km/h-550km/h, compares the different alleviative effect of the three different hood to max micro-pressure wave and finally proposes the reasonable construction pattern of the tunnel portal.

本文针对国家高技术研究发展计划(863计划)课题"磁浮交通沪杭线越黄浦江隧道的工程技术问题研究"，在单洞单线和单洞双线两种工况下，对隧道洞口的合理结构形式和影响范围，以及洞口喇叭形入口缓冲段、多孔壁入口缓冲段以及隧道出口膨胀室对减缓微压波的作用进行了研究，得到了磁浮列车速度在100km/h～550km/h时隧道出口微压波最大值与速度的关系以及微压波最大值与测点距离的关系，比较了三种不同形式缓冲结构对微压波最大值的减缓效果，提出了隧道洞口的合理结构形式。

The following data were compared respectively between two groups ,such as operation time, exploratory rate of other diseases in peritoneum,time of post-operative anal exsufflation and ambulation,operation expense,the amount of analgesics patients need after operation,the incidence of incision infection,adhesive intestinal obstruction and residual infection in abdominal cavity.

The following data were compared respectively between two groups,such as operation time,exploratory rate of other diseases in peritoneum,time of postoperative anal exsufflation and ambulation,hospitalization expense,the amount of analgesics patients need after operation,the incidence of incision infection,adhesive intestinal obstruction and residual infection in abdominal cavity.

回顾分析60例腹腔镜阑尾切除术（laparoscopic appendectomy，LA）和同期OA组60例的手术资料，比较两组手术时间、腹腔内其他病变探查率、术后肛门排气时间、术后下床时间、住院费用、术后止痛剂使用、切口感染、粘连性肠梗阻、腹腔残余感染发生率等指标。

It is interesting to speculate on whether hip extensor/flexor imbalance might also be associated with the relatively high incidence of groin injuries.

这是个有趣的猜测是否髋关节伸/屈不平衡，也可能与较高的发病率腹股沟受伤。

The patients expressing ER have a better prognosis than ER negative patients,because of lower incidence of microsatillites,and extracapsular invasion,lowerPCNA LI and early stage.

3，由于ER阳性的肝癌多有完整的包膜、较低的子结节或卫星灶伴发率以及较低的PCNA标记指数，提示其预后要好于ER阴性的肝癌。

In the 2×2 electro-optic switch with oblique incidence, the angular separation Δ〓 between the ordinary ray and extraordinary ray can be much greater if the output end interface are properly designed.

在斜入射2×2电光开关中改变出射面的光轴方向，可以使o光和e光的分离角Δ〓更大。

Furthermore, for angles of incidence other than 0o, Snell's law (that is, sin I /sin γ=constant) holds for the ordinary but not for the extraordinary ray, since the velocity of the latter is different in different directions.

此外，入射角如果大于零度，根据折射定律(sin I /sin γ=常量)适合于寻常光，但不适于非常光线，因而在不同的方向有不同的速度。

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

将实验动物随机分为生理盐水组，阳性药物对照组，藏红花酸高、中、低剂量组，SD大鼠采用1.2 g/kg乌拉坦麻醉后，从尾静脉匀速(0.1 ml/min)灌注10μg/ml乌头碱溶液，豚鼠麻醉后从颈静脉匀速(0.1 ml/min)灌注9μg/ml哇巴因溶液，观察出现室性期前收缩、室性心动过速、室颤和心脏停搏的时间，然后换算成乌头碱和哇巴因的累积量；快速推注4%氯化钙(140 mg/kg)诱导大鼠心律失常，观察给药后心律失常出现时间、持续时间、心律失常发生数及死亡数。

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。
