两个一组

After one month the effect and result s of two groups are compared.

两组一 个月后测量疗效和结果比较。

Stability of implants was measured by rfa regularly.results there was no significant difference between both groups about stability at all periods and histomorphometry, but isq, bic and ba of experimental group were higher than control group, and isq recovered more quickly in experimental group after loaded.conclusion dual threads design contributes to assure the initial and secondary stability of implants, which is particularly important in poor density bone.

结果 两组种植体在各时期的稳定度差异均无显著性，但在每一时期实验组种植体的稳定度均较对照组高，实验组种植体在负重后稳定度恢复较快，负重3个月后实验组的骨-种植体接触率和种植体周围骨面积均较对照组稍高，但两者差异无显著性。结论双梯形螺纹种植体有利于保证种植体的初期和后期稳定性，应用于低密度骨质优越性会更加明显。

Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.

充分利用了射影几何中交比和调和共轭的知识以及正方形模板对角线相互垂直的性质，根据一幅模板图像可以得到两组相互正交的消失点连线，在至少三个不同方向拍摄的图像上线性求解出摄像机的所有内部参数。

Methods We randomly assigned young boys with severe hemophilia A to regular infusions of recombinant factor VIII or to an enhanced episodic infusion schedule of at least three doses totaling a minimum of 80 IU of factor VIII per kilogram of body weight at the time of a joint hemorrhage.

研究人员将65名30个月龄以上的重度A型血友病男孩随机分为两组，32名患儿规律注射重组VIII因子25IU/Kg，隔日一次，另外33名则在关节出血时注射重组VIII因子至少3个剂量，总量最少要达到80IU/Kg。

At a mean follow-up of 15 months (range, 10-19 months), 19 (65.51%) of 29 patients had excellent results, and nine patients (31.03%) had acceptable results. HolCTU failed to maintain good flow in the latter group, necessitating internal urethrotomy/endoscopic dilation once or twice for stabilization (maximal flow rate 15 mL/s or greater). One patient (3.44%) had recurrent obstruction despite repeated internal urethrotomy, which finally required formal transpubic urethroplasty. All of the patients were continent, with no change in potency status.

经过15个月的后续追踪(范围在1 0-19个月)，29位患者中有19 位(65.51%)患者有极佳的效果，另有9位(31.03%)患者有可以接受的效果；不过，后面几组无法以尿道造口术维持好的流动，为了稳定流速，需要一至两次内部的尿道造口术/内视镜扩张术(最大流速为5 mL/s 或更大)；有1位(3.44%)患者虽然重复接受内部尿道造口术，但是一再发生阻塞，患者最后需要经正规的耻骨尿道成形术，全部患者可在不影响性功能的情况下控制排尿。

The experimental group for the dimethyl biguanide plus fuzhenghuatanhuoxue prescription, and the control group for dimethyl biguanide only.

两组患者均给予糖尿病教育，饮食控制，适量运动，根据血糖情况调整二甲双胍的剂量，2个月为一疗程。

After treating for 3 menstrual cycles, assayed clinical symptom , dysmenorrheal score , clinical traditional Chinese medicine symptom score and serum levels of hemorrheology to contrast clinical therapeutic effect of the two groups.

以3个月经周期为一疗程，通过比较两组病人治疗前后病情疗效、中医证候疗效、痛经症状积分及血液流变学情况的变化结果，对两种方法的临床疗效进行评价。

All of the two groups were treated by chemotherapy with a regimen of 2HRZE/10HRE and Intrapleural injection of urokinase by aspirating pleural effusion or pleural drainage. The observation group were treated with plasmin intravenous infusion for 3 courses (Seven days per course and then five days interval).

两组均采用抗结核化疗方案2HRZE/10HRE及胸穿抽液或胸腔内置管引流，并胸腔内注入尿激酶；观察组静滴纤溶酶7d一疗程，每疗程间隔5d，共3个疗程。

METHODS:Treatment records of 1100 teeth with acute or chronic pulpitis or chronic apical periodontitis were compared.

选择患急、慢性牙髓炎和慢性根尖周炎 80 0例 110 0个患牙，随机分为两组，对照组 5 14牙采用常规根管治疗术即两次法，实验组 5 86牙采用一次法进行根管充填，观察各组术后近期临床反应。

The following contents are involved: First, in order to understand the load-bearing capacity of new type of light gauge steel system studs, 5 full-size static tests were carried out, and researches were done on it.

主要包括以下几个方面的内容：一、为了了解轻钢龙骨体系柱的承载能力，做了两组共五个足尺试件的静力测试，对其承载能力进行了试验研究。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
