Anesthesis was performed by interscalene brachial plexus block.the onset and duration of analgesia,the level of block as well as adverse effects were recorded.hr and map were measured before anesthesia,5,10,30 and 60 minates after anesthesia.results:the onset time of block was significantly shorter and shivering was significantly lower in groups two and three as compared with group one.there was significant difference in the duration of anesthesia between group two and group three.

肌间沟法行臂丛神经阻滞，观察阻滞起效时间及持续时间、神经阻滞节断数、术中镇痛质量、不良反应以及注药前、注药后5、10、30、60分时心率和平均动脉压。结果：二、三组麻醉起效时间短于一组（p＜0.05）；麻醉持续时间二、三组长于一组但差异无显著性；二、三组组间比较差异有显著性；各组阻滞节断数、术中牵涉痛发生率、hr及map差异无显著性；一组寒战发生率高于二、三组（p＜0.05）。

Methods In this randomized, double-blind trial, we compared 4 years of therapy with either tiotropium or placebo in patients with COPD who were permitted to use all respiratory medications except inhaled anticholinergic drugs.

该试验为随机双盲试验，我们将COPD患者分为两组，一组为噻托溴铵组，另一组为安慰剂组，可以使用除吸入性抗胆碱能药物外的所有呼吸系统用药；然后比较这两组患者4年的疗效。

The main chemical constituents of R.crenulata included geraniol (14.78 - 55.11%), n-octanol (13.39 - 39.45%),2-methyl-3-buten-2-ol (0.82 - 24.15%), citronellol (2.18 - 8.86%),3-methyl-2-buten-1-ol (0.49 - 9.22%), mytenol (trace - 9.41%), linalool (1.41 - 4.05%) and so forth.

居群间的遗传距离 UPGMA 结果与地理分布相关性较高，9个居群聚成3组：西藏的2个居群聚成一组；云南德钦地区的2居群聚成一组；云南丽江居群与香格里拉红山铜矿居群聚成一组。

Methods divide 120 cases of closed fracture of tibia diaphysis into two groups under the same possible circumstances.each group has 60 cases. one group was treated by operating replacement, the other group was treated by closed replacement. two groups were treated by unilateral external fixation apparatus to fix after replacement.

选择120 例胫骨干闭合性骨折的患者，在条件尽可能相近的情况下分为两组，每组60 例，一组采用切开复位，另一组采用闭合复位，复位后两组均使用单边外固定架固定。

The integer 62 953（see Fig.4-1）could be seen as a collection of digits stored on the page in a left-to-right order.Each digit一6,2,9,5,and 3一could either be considered to be atomic or be viewed as collections of dots of ink（suppose we are using a dot-matrix printer）.

整数62 953（见图4-1）可以看成是一个储存在本页上，由一组按从左到右排列的数字汇集，每位数字（6、2、9、5和3）既可以看成是原子，也可以看成墨点汇集（假设我们使用点阵打印机）。

In a double-blind, placebo-controlled design we randomized 120 children, aged 1-9 yr, undergoing orthopedic or soft tissue surgery, into 3 groups to receive either acetaminophen 60 mg/kg rectally and 40 mg/kg orally, ketoprofen 2 mg/kg IV twice, or the combination of the active drugs.

在这项双盲、安慰剂对照试验中，我们随机抽取了120个一至九岁的行软组织或畸形矫正手术儿童，将他们分成三组，一组为经直肠给扑热息痛60 mg/kg 或口服给药40 mg/kg ，一组为静脉给优布芬2 mg/kg，另一组为联合给药。

Firstly, an inverse eigenvalue problem for Jacobi matrices is presented: we could construct the Jacobi matrix T if we know the spectral data: the eigenvalues of T and the eigenvalues of T_1 and of T_2, where T_1 is different to the k × k leading principal submatrix of T only at the position, while T_2 is different to the × remain submatrix only at the (1, 1) position.

首先给出的是一类Jacobi阵的逆特征值问题，即给定三组实数：一组是Jacobi阵的n个特征值，一组是只修改了最后一个对角元的它的前k阶顺序主子阵的特征值，最后一组是修改了第一个对角元的后n—k阶余子阵的特征值，用这些给定的特征值来确定相应的Jacobi矩阵。

CPAP patients were diided post hoc into those whose apnea-hypopnea index was or was not reduced below 15 at this time (CPAP-CSA suppressed, n=57, and CPAP-CSA unsuppressed, n=43, respectiely).

CPAP组患者被分成两组，在这段研究期间，一组的平均呼吸暂停-低通气指数到每小时睡眠15次事件以下，另一组则平均呼吸暂停-低通气指数到每小时睡眠15次事件以上 CPAP-CSA 治疗组，n=57例，未作CPAP-CSA 治疗组， n=43例

Scientists believe that the giant-impact theory may also solve some other outstanding puzzles of the earth'makeup-一for example,why vei of heavy metals such as gold and platinum lie shallow enough to be mined."The impact scenario explai that all in one shot."

科学家们相信大碰撞理论也许解决了另外一些关于地球起源的难题，例如，为什么像金子和铂这样的矿藏埋藏在足够浅的地表而容易被人采掘，&碰撞的演示在一组画面里就解释了这一切。&

The control group was administered western medincine only and the observed group wos administered Shenmai injection combined with western medicine .The patients in the observed groups were treated with Shenmai injection 60ml(adding Shenmai injection to 100ml if the patients had low blood pressure) for intravenous dropping,once a day and the therapeutic course was 7 days.

将1 108例病例分为两组，每组各为554例；一组予单纯西药治疗；另一组为在使用西药的基础上加用参麦注射液的治疗组，其方法为每日静脉滴注1次，剂量为60 ml，(合并低血压者，可将其剂量增加至100 ml)连续使用7 d，然后对比两组的疗效。
