有所发现

At the location of the south polar vortex for the normal year, the mixing ratios of O3 and CH4 increased, HCl and NO decreased, but NO2 and H2O did not accord with a given rule at all altitudes over Antarctica in 2002, which was related to the change of the vortex and the dynamical transportation after the SSW, and affected by the reduced polar stratospheric clouds and weakened processes of heterogeneous chemistry.

通过比较还发现，在通常年份极涡所处的位置上，2002年O3和CH4的混合比有所增加，HCl和NO的混合比有所减少，而NO2和H2O在不同高度上的变化特点不同。这与爆发性增温之后极涡和动力输送的变化有关，同时由于增温导致极地平流层云中相关冰相反应的减弱也是一个重要的原因。

Conversely, if our conclu-sion unearths new information from the gene-ral market, we may have discovered something interesting here.

相反的，如果我们的结论是超出一般观点，那我们可能有所发现。

Subject this after studying and finding by diatom land reform, needle of pitch enter degree reduce, fall as low as most getting 70 (0.01cm), is it rise a bit to soften, height 50.06 ℃most, asphalt residue stability degree of mixture move steady degree improve to some extent, stating the high-temperature stability on the pitch road surface, water and stability, resist the serviceability , such as aging ability ,etc.

本课题经过研究发现经硅藻土改性后，沥青的针入度降低，最低达到70（0.01cm），软化点升高，最高为50.06℃，沥青混合料的残留稳定度及动稳定度有所提高，说明沥青路面的高温稳定性，水稳定性，抗老化能力等使用性能都得到改善；用水煮法对沥青混合料进行了粘附性进行测试表明，粘附性从3或4提高到4或5；硅改沥青的当量软化点，针入度指数等高温性能的研究发现，硅改沥青的高温性能有所改善；对粘弹指标的研究表明改性沥青的流动性变小；对抗水损害能力的研究表明，抗水损害能力有所提高。

Nonetheless, there is always hope — as summiteers could discover if they consider their surroundings.

然而，希望总是存在的——如果与会者仔细考虑周遭事物的话，他们会有所发现的。

Nearly twice as many firms noted a rise in the number of "sickies" taken by staff in recent years than those that had seen an improvement.

这里的improvement指的是请病假这种状况改善的公司，就是&发现病假数有所增长的公司是那些发现这种状况有所改善公司的几乎两倍多&

In a survey of companies in Europe and America by Mercer, a consultancy, nearly twice as many firms noted a rise in the number of "sickies" taken by staff in recent years than those that had seen an improvement.

美世咨询公司对欧洲和美国的公司做了一项调查，发现近些年来，病假数有所增长的公司是那些发现这种状况有所改善公司的将近两倍。

In view of these facts, We tried to find something in the L-form induction, plasmid extraction and their function, and the cloning and expression of promotors from BCG in Bacillus subtilis. Our aim is to provide a basis for the expression of HBsAg gene in BCG and to add something to the molecuiar biology of mycobacteria.

正是有鉴于此，我们试图在分枝杆菌在液体培养基中的L型实验诱导、质粒的提取及其功能分析、卡介苗启动子在枯草杆菌的克隆和表达等方面有所发现，为利用卡介苗表达乙型肝炎表面抗原基因提供基础，也为我国分枝杆菌的分子生物学研究增加内容。

Records of this type of wheel have been found among Egyptian relics dating back to 2000 B .

轮子的记载已在古埃及遗迹中有所发现，可以追溯到公元前2000年；在早期的中国文明中也曾独立发明过类似的机械装置。

In the long history of man's inventiveness, discoverers seem to fall into two classes, The first is the ingenious person who sets out to find the solution to a problem.

在人类发明创造的漫长历史上，有所发现的人看来可分成两类，第一种是有心去寻求问题答案的人。

Holocene"periglacial phenomena"were found at many places continuously. However, by comprehensive study, this thesis believes that these"periglacial phenomena"are almost the results of seasonal freeze-and-thaw action, not the strict periglacial phenomena. Only in some high mountain areas and northeastern zigzag zone of farming and animal husbandry, there were periglacial phenomena developing conditions in the cold stage of the Holocene.

我国北方农牧交错带全新世的&冰缘现象&不断有所发现，但本文经过综合研究后认为，这些&冰缘现象&绝大部分都是季节性寒冻作用的产物，而非严格意义上的冰缘现象，只有局部中高山地区和北方农牧交错带东北部现代气温在0℃以下的地区，全新世低温期才具备发育冰缘现象的条件。
