It were found by comprehensive analysis, the precisive diagnosis rates of the markers from bronchoalveolar lavage fluid were much higher than that from blood, and the markers from alveolar macrophage were much higher than that from broncholaveolar lavage fluid. The precisive diagnosis rates of fibronectin secreted by alveolar macrophage, and fibronectin secreted by alveolar macrophage inhibited by cort and inhibitory rate were 96. 2%, 92. 3%, and 92. 3%, with the diagnosis markers of higher sensibitity and specificity.

综合分析发现，支气管肺灌洗液中指标的正确诊断率高于外周血，而肺泡巨噬细胞中诊断指标又优于支气管肺灌洗液，其中肺泡巨噬细胞产生的纤维结合蛋白、皮质激素抑制肺泡巨噬细胞产生纤维结合蛋白和纤维结合蛋白抑制率均为敏感性和特异性较高的诊断指标，其正确诊断率分别为96.2%、92.3%和92.3%。

Friction tests in moving water and field sheer tests and seepage model tests and the effects of seepage defending and rough ratio tests and the capacity of resisting from frozen bulge and ice pressure. 2. Through the series track ageing tests of geosynthetics for 14 years, if the covering is 40cm thick and the initial strength is more than 500N/5cm, the geosynthetics can be used for at least 50 years, most to be more than 100 years. Under the same conditions, the strength and elongation of geotextile are both decrease, and for geomembrance the strength increased in early days. One important ageing index for geomembrance is embrittlement.

2通过工程现场14年的取样，进行老化试验分析，结果显示，土工合成材料在40cm厚以上岩土严密保护的条件下，初始强度大于500N/5cm，使用年限至少可达50年，多数情况可超过100年；在同等条件下，土工织物老化在力学性能上的表现是强度和延伸率都呈下降趋势，而多数土工膜在初期力学性能上表现是强度增加延伸率下降，到后期强度和延伸率才都呈下降趋势，脆化是衡量土工膜老化性能的重要指标。

Results: It was necessary for puerperant to correctly make perineotomy parturition.The rational rate of perineotomy was about 37％.For the primipara,the perineotomy rate should be controlled approximately 49％.

结果：合理的会阴切开阴道助产是非常必要的，会阴切开阴道助产率在37％左右为好，初产妇应控制在49％左右较为合适，在此侧切率下新生儿窒息率为6.6％，产妇并发症、后遗症约5.58％。

The mathematical model of risk probability of the criteria of river diversion is established.

分析了影响导流标准风险的各种不确定性因素，建立了施工导流标准风险率的数学模型，并通过对风险率模型性质的研究，给出了风险率的点估计和区间估计的计算公式。

The thresholds are dynamically adjusted according to the difference between the target bit rate and actual bit rate. This method can reduce the bit rate of intra coded frames while still maintating error robustness and limiting temporal propagation of errors.

该方法根据目标比特率和实际比特率的差值，动态地调整阈值，从而有效地减少了帧内编码的比特率，保持了对差错的鲁棒性，限制了差错的时间传播。

NO_x decreasing ratio of micronized coal reburning comparing withgeneral combustion is not proportionable to NO_x reduction ratio in reduction zone,which depends on both NO_x reduction ratio and NO_x increment in burnout zone.

超细粉再燃与常规燃烧相比NO_x脱除率与再燃区NO_x还原率不成正比，它是由NO_x还原率与燃尽区NO_x新的生成综合决定的。

Results: The total effective rate in union treatment group was 92.8%, the rate of purpuric nephritis is 7.1% after 4 weeks treatment, and the Recurring rate is 10.7% after 6 months. The effective rate of normal dose gamma globulin group was 89.7%, the rate of purpura nephritis is 10.3% after 4 weeks treatment, and the Recurring rate is 13.8% after 6 months.

结果：联合治疗组有效率为92.9%，治疗后4周紫癜性肾炎发生率为7.1%，随访6个月后复发率为10.7%；丙球治疗组有效率为89.7%，治疗后4周紫癜性肾炎发生率为10.3%，随访6个月后复发率为13.8%；对照组有效率为73.3%，紫癜性肾炎发生率及复发率均为33.3%。

The results show that: the functional groups in coal are the function of coal rank , and the yields of CO 2, H 2O and CO are related to the content of carboxyl, hydroxyl and other oxygen containing groups such as ether groups in coal, and Tar and CH 4 are related to the aliphatic CH, the char yields to the aromatic CH.

借助化学分析和FTIR光谱分析对我国煤化程度不同的18 种煤中官能团的研究表明：煤中官能团含量与煤化程度有关；煤中羧基、羟基及醚键等其他含氧官能团的含量与热解生成物CO2、H2O 和CO 的产率有关，脂肪—CH 的含量与甲烷和焦油的产率相关联，芳香—CH 的含量与热解半焦产率有关。

The average occupation ratio is about 70 percents. The hotel with the highest 90 percent and the lowest 45 percent ratio account for 15.6 percent and 10.5 percent receptively.

除非典等不可抗力因素外，酒店平均客房入住率达到70%，入住率达到90%的酒店占15.6%，入住率最低为45%的酒店占10.5%。

The computation of sky radiance resulted from the earth's diffuse reflection is studied based on a hypothesis that a underlying surface is randomly rough. The paper gives an analysis of the method to calculate the reflectivity, average hemisphere reflectivity, and transmission in virtue of the reciprocity law from the earth's surface to the top of the atmosphere.

本文基于下垫面为朗伯粗糙表面的假设基础上，对下垫面对向下太阳辐射的漫反射作用引起天空亮度变化的计算方法进行了研究，分析了利用互易性原理计算大气反射率、半球平均反射率和透过率的方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
