The paper takes Breakingfruit Chinkapin fibre and other wood fiber compound manufacturing MDF's Processing-parameter for research object. Use the diagonal intersection trial law designing the trial scheme. The focal point is studied the major Processing-parameter of Breakingfruit Chinkapin with other woods to manufacture MDF. And internal bond strength, modulus of rupture, modulus of elasticity, formaldehyde emission content, thickness expansion rate of water absorbing and density of MDF are analysed. From Variance, Range and other methods seek the better Processing-parameter.

本文以黎蒴栲材热磨纤维与其他树种热磨纤维复合制造MDF工艺为研究对象，采用正交试验法设计试验方案，并根据国家标准规定的测试方法对压制成的MDF的内结合强度、静曲强度、静曲弹性模量、甲醛释放量、吸水厚度膨胀率等多项性能进行分析，利用方差、极差等分析手段寻找合理的制造工艺参数。

And we say because of the meta-analysis showing that β blocker in general and Atenolol in particular may not be as effective as other anti-hypertensive drugs, because of the LIVE trial, because of the ASCOT trial, which shows that the atenolol and thiazide are less effective than the amlodipine and thiazide arm.

之所以这么说是因为，有荟萃分析显示，β受体阻滞剂，具体说来就是阿替洛尔的疗效不如其他降压药物，LIFE试验、ASCOT试验的结果都支持这一点，这些试验的结果显示，阿替洛尔和噻嗪类利尿剂联合治疗的疗效比不上氨氯地平和噻嗪类利尿剂联合治疗。

本研究通过饲养试验和微生物试验比较了甘露寡糖、糖萜素和金霉素对肉仔鸡生产性能及肠道菌群的影响，以期探讨甘露寡糖和糖萜素在肉仔鸡饲粮中替代金霉素的效果。

This method includes the method of profile data modeling in theory, bound searching method of expansion polar angle corresponding theoretical points and evaluation method of least-deviation profile error.

包括实现轮廓度测量的理论轮廓数据建模方法、对应理论点的扩展极角定界搜索方法以及满足最小条件的最小极偏差轮廓度误差评定方法。

The findings indicated that the results of the nonparametric method and the parametric method were quite close to that of the original sample. However, the standard errors of the parametric method were slightly higher than that of the nonparametric method; especially the standard error of the level-1 residual varianceσ?

研究结果表明，非参数法和参数法的拟合结果多数与原始样本比较接近，只是参数法的标准误相对较非参数法稍大，尤其是水平1残差方差σ？

The impact of precommercial thinning on tree growth and stem quality in jack pine was examined.The study was based on a PCT trial established in 1966 in New Brunswick,Canada.Three thinning intensities,1.22m×1.22m,1.52m×(1.52m),2.13m×2.13m,and a control stand were studied and a total of 154 sample trees were collected from the trial.

以加拿大新布郎斯威克省自然资源与能源部1966年建立的天然林抚育间伐实验基地为研究对象，从3种疏伐强度(1.22 m×1.22 m，1.52 m×1.52 m，2.13 m×2.13 m)的样地和一块控制地中共采伐了154株树，胸径范围10~24 cm，研究抚育间伐对北美短叶松的生长及材质的影响。

Meanwhile, the choice has been made by comparing two kinds of jury systems, and then, the author put forth a kind of way to rebuild our trial system, that is, to establish a diversified trial system, which includes trials by juryman, trials by the jury and trials by the judge, and the possibility of this kind of system has been proved.

一方面，一再完善参审形式的改革好像没有改变人民陪审制缺乏实效的状况，另一方面，引进陪审团审判我国的国情民意是否接受需要尚需艰难论证，其巨大成本也使多数人望而生畏。

Methods 256 patients with bacterial vaginosis were randomly divided into control group (n=126) and trial group (n=130).Control group were given metronidazole tablets and trial group were given secnidazole tablets.The clinical efficacy was compared between two groups 3~7 days after the end of treatment and 3~7 days after menorrhea,respectively.The relapse rate during 3 months after the end of treatment between two groups was compared.

256例细菌性阴道病患者随机分成对照组126例和试验组130例，分别给予甲硝唑片和塞克硝唑片口服；停药后3~5 d及停药后下次月经来潮干净后3~7 d比较两组的临床疗效，比较两组3个月内的复发率；并观察两组的不良反应的发生情况。

1.Preliminary studys on the carotid artery parameters Detected by Intracavitary Convex Array ProbePurpose and SignificanceFinal results of The North American Symptomatic Carotid Endarterectomy Trial and the MRC European Carotid Surgery Trial displayed that carotid artery must be observed intimately when stegnosis degree is higher than 50%and it must have an operation or interventional therapy in time when stegnosis degree is higher than 70%.
