Whether the inner cylinder is drilled or not do not affect obviously the measurement accuracy. The accuracy of the drilled outside cylinder is higher than the undrilled ones, and the drilled holes are better to be equally distributed, further more, the number is less than 36 with the diameter of 3mm. The sealed outside cylinder can lower the measurement accuracy. The thinner material of sealed inside cylinder is and the more ventilative function is, the higher accuracy will be achieved. Moreover, when the space between inside and outside cylinder is smaller, the measurement accuracy also becomes higher.

结果表明：各处理精度均较高，最高达97.40%；内筒打孔与否对测量精度无显著影响；套筒打孔的处理比不打孔的处理精度更高，且孔洞适宜均匀分布，但数目不可过多，直径为3mm时不宜超过36个；套筒封底会降低测量精度，内筒封底材料越薄、透气性能越好精度越高；内筒与套筒的间隔较小时精度更高。

The partly significant difference-at time consuming weathering tests - could until now only be demonstrated unsatisfactorily with the traditional test methods .

在费时的风蚀试验中，人们发现了一些显著的区别，这些区别是目前传统测试方法所不能圆满表征的。

The individual-level analyses suggest that, the unstandardized and age-sex standardized disability concentration index are -0.1179 and -0.0453, respectively, which are systematically deviate from 0; and the negative concentration index indicate the existence of pro-rich income-related health inequality.

个体水平的分析结果显示，4区合计，未标化和经年龄和性别标化的伤残集中指数分别为-0.1179和-0.0453，均系统性地偏离0，而且集中指数为负，提示收入相关健康不平等的存在，并且伤残显著集中于低收入人群。

The study finds that the AOC in sand filtrated water does not change significantly at different ozone dosages. Considering disinfection and oxidation, the optimal ozone dose should be controlled at 1 to 2 mg/L.

研究发现，不同的臭氧投加量下砂滤水的 AOC 变化不显著，考虑氧化作用和消毒效果，认为最佳的臭氧剂量应控制在1-2mg/L 。

With the porous hulls of other grains, steam easily passes through , so no significant pressure is produced.

由于其它的谷物的有孔外壳，蒸汽很容易外泄，因此不能形成显著的压力。

The result showed that 83.1% of whitefly nymphs were present on top and middle leaves and there was no marked difference between middle and top leaves;significant difference was observed on the distribution of whitefly nymphs among different podding habit soybean varieties.

结果表明烟粉虱若虫在夏大豆植株上的总体分布集中在中上部，占总数的83.1%，中部与上部之间差异不显著。不同结荚习性大豆品种上烟粉虱若虫的分布存在明显差异。

Sequence analysis and homology searches of public data bases, however, revealed no published sequences significantly similar to the sequence of the fragment, precluding a predicition of the potential function of the sequence.

但DNA序列分析和数据库检索表明，该片段与迄今发表的核酸序列均不存在显著的同源性，因此尚无法预测其潜在的功能性。

Main Outcome Measures Daily counts of county-wide emergency hospital admissions for primary diagnoses of cardiovascular or respiratory disease.

PM10-2.5 或 PM2.5与因特别原因造成的心血管疾病和呼吸性疾病的后果之间不存在显著的相关性。

PM10-2.5 或 PM2.5与因特别原因造成的心血管疾病和呼吸性疾病的后果之间不存在显著的相关性。

In recent years, some non-metallic corrosion materials, such as plastic, fibreglass, glass, ceramics and not revealed sexual graphite, in the chemical production of a wide range of applications received and achieved remarkable results.

近年来，一些非金属防腐材料，如塑料，玻璃钢，玻璃，陶瓷和不透性石墨等，在化学生产中得到的广泛的应用，取得了显著的效果。

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。
