短时间

As the night progresses, however, non-REM stages shorten and the REM periods grow, giving us a 40-minute dreamscape just before waking.

随着夜晚逐渐过去，非快速眼动的时间在变短，而快速眼动的时间在增加，醒来前的那一次快速眼动，可能带来40分钟的梦境。

Material and Methods:From March,2008 to January,2009,250 patients(146 Males and 104 Females,ranged from 18 to 82 years old,mean age was 48 years old) enrolled in the First Affiliated Hospital of Kunming Medical College were performed dual energy scan(Group A,200 patients) and Neuro-DSA scan(Group B,50 patients) using DSCT.The patients were randomly divided into Group A and Group B.Regarding to the justification of scan protocol,100 patients in Group A were selected as sub-group to explore the scan protocol.The image quality Was analyzed both in four categories(4.0/60、4.5/60、4.0/70、4.5/70) of flow rate and total amount of contrast-enhanced material and in three categories(100—150HU、150—200HU、200-250HU) of CT value of left common carotid artery.The comparison of two scan approach was based on image quality,radiation does, postprocessing methods,time of scanning and subtraction and data storage amount.To validate the diagnostic capability of DE-CTA virtual unenhanced images,100 patients in Group A were undergoing head scan both in routine non-contrast program and DE-CTA virtual unenhanced program.Mean CT values,signal-to-noise ratio,image quality,sensitivity of lesion identification,and radiation does were applied to comparison.According to diagnostic results of dual energy of cerebral arterial angiography,62 patients out of 200 patients in Group A were confirmed with cerebral vessel lesions,the results were complied with DSA findings(the time between the two methods were within 1 week).

材料与方法收集2008年3月到2009年1月间在昆明医学院第一附属医院行DSCT CTA检查者250例(男性146例，女性104例，年龄范围18-82岁，平均48岁)，随机分为A、B两组，A组200例行双能量头颅CTA扫描；B组50例行Neuro-DSA扫描。A组前100例按对比剂不同流率和总量分为4组(4.0/60、4.5/60、4.0/70、4.5/70)对图像质量比较；按触发时左颈总动脉内平均CT位分3组(100—150HU、150—200HU、200-250HU)，比较图像质量的差异；对A、B两组血管图像质量、辐射剂量、后处理的方法、扫描和后处理时间及数据的容量进行比较分析；A组中前100例行常规与DE-CTA虚拟平扫的平均CT值、信号噪声比、图像质量、病灶显示情况、辐射剂量的比较分析；A组中行DSA检查62例(两种方法间隔时间均1周内)，比较两种检查方法诊断结果是否符合，并对其中24例动脉瘤行动脉瘤部位、数目、形态、瘤颈显示程度、瘤颈大小及瘤体长径和短径的比较研究。

Results The result showed that 0.7% and 1% sodium pentobarbital anesthesia duration was too short, 1.5% pentobarbital sodium easily made animal deaths, and 10% chloral hydrate used for anesthesia in mice was appropriate. And the glass cannula was more suitable than adhesive bandages for enswathement.

结果 0.7%和1%戊巴比妥钠麻醉持续时间过短，1.5%戊巴比妥钠和10%水合氯醛能维持足够手术操作所需的时间，但1.5%戊巴比妥钠易导致动物死亡，故采用10%水合氯醛麻醉小鼠较合适；玻璃套管法包扎的效果较创可贴法为好且更简便。

Serving to save time through an efficient method or a shorter route; expeditious.

可节省时间的可通过一个有效的方式或一个更短的路径节省时间的；迅速的

Based on such insufficient information, it is fallacious to draw any conclusion at all .

而且在题目中说到第一组使用抗生素平均比预计的标准的或普遍的恢复时间短40％，但作者并未说明这个预计的标准恢复时间是从使用何种药物，病人的病情和医疗条件下得出的，所以由此比对而得出的结论也不可靠。

The effects to which stations attract passenger flow, trip time, cost, real estate along line, URT feeder other traffic, structure and configuration of city were analyzed. Based on the minimize trip time of passenger, the model of optimal average distance between URT's stations and the model of station's coverage and the model of station's cost and benefit were proposed.

分析车站分布对吸引客流、乘客出行时间、工程造价、运营及沿线土地开发、城市轨道交通与其它交通方式的衔接、城市空间结构和城镇体系布局的影响；建立了基于乘客出行时间最短的最优平均站距模型、车站选取的覆盖量模型与费用效益模型。

The series of tempting talent soon builds to fever pitch, and as time is money, and never more so than in the publicity business it is lucky we are dealing with fast workers.

参与拍摄本系列的精英们都是经验百战的老手，时间就是金钱，这道理在演艺界更是重要，还好我们的工作人员的办事速度都非常快，才能在这麼短的时间里面给观众推出这麼棒的一部成人电影。

Once he is used to seeing the halter, get him used to wearing it unfastened for short periods of time.

一旦他习惯看到了阿尔泰，让他用来穿着它unfastened时间很短的时间。

The relation between the center of time gravity of the ultrashort pulse and the carrier phase was studied by using three kinds of pulses,named Gauss,Hyperbolic Secant and Lorentz pulses.The analytical expressions of the relation between them was deduced.

以Gauss、Hyperbolic Secant、Lorentz三种脉冲为例，利用理论推导和数值模拟的方法研究了载波相位对超短脉冲时间重心的影响，并给出了三种脉冲的时间重心与载波相位的解析表达式和数值模拟的图形。
