By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

Physical stability of liposomes plays the critical roles in various stages of the applications and development of liposomes. In this study, we applied low molecular weight chitosan to modify the liposomes surface, and investigated the physical stability of liposomes, Moreover, we encapsulated cantharidin to study the effects of chitosan which cause drug leakage.

微脂粒稳定性的研究在其应用发展上占有举足轻重的影响，因此本研究利用低分子量水溶性几丁聚醣来修饰微脂粒表面，观测几丁聚醣对微脂粒物理稳定性的影响，同时也一并探讨包覆抗癌药物斑蝥素，几丁聚醣对微脂粒包覆斑蝥素的渗漏情形。

Among the above symptoms and signs, some of them like cyanosis of lips, purplish tongue, varicose sublingual vein, headache, blackish eyelids, tongue with ecchymosis, blackish complexion, squamous and dry skin, pain on the paralytic limbs, dermorrhagia are the conventional ones, the others like flaccidity of lower extremities, hemianesthesia, dispiritedness, dysphasia, distension of stomach and abdomen are found by us.

当然，其中主要是一些传统的血瘀证症状、体征，如唇色紫暗、舌质紫暗、舌脉曲张、睑下青黑、舌有瘀斑、面色晦暗、肌肤甲错、瘫肢疼痛不移、肌肤青紫/有瘀斑，但也有一些症状和体征是以往并不常作为判断血瘀证的，如下肢肌力减弱、偏身麻木、精神萎靡、言謇失语、脘腹胀满，为脑梗塞血瘀证的诊断增加了新的依据。

The results showed that foraging frequency of Pluvialis dominica was lower than that of Calidris temminckii significantly.

结果表明，金斑鸻的觅食频率显著低于青脚鹬的觅食频率，金斑鸻和青脚鹬的觅食频率均随干扰程度的增加而下降。

The phylogenetic analysis of 22 ND4L sequences of Phocidae from GenBank showed that there are two clades (which belong to Northern Group and Southern Group) supported by relatively high bootstrap value and there are more closed relationship between spotted seal and harbor seal.17 haplotypes with 717bp were obtained from the mtDNA control region, adjacent proline and a portion of the threonine tRNA genes of 46 individuals.

利用从GenBank中下载的22个海豹科动物的ND4L基因序列的系统进化分析表明，海豹科动物分为南半球和北半球两大类群，斑海豹与港海豹为北半球种类，亲缘关系最近。从46个辽东湾斑海豹线粒体DNA控制区和苏氨酸及脯氨酸tRNA基因717bp片段的测序，得到17个单倍型。

Firstly, the principle and the techniques of measuring the displacement on surface using quadratic-exposure speckle charts were introduced, and the meterage of thickness and nonuniformity of transparent solid using laser speckle techniques was discussed.

首先介绍了应用二次曝光散斑图测量物体表面的面内位移的原理和方法；在此基础上论述了激光散斑技术针对透明固体的厚度及其非均匀性的测量。

Part II: The structural modification of norcantharidin and the discovery and applications of NCS-DMSO combinatorial system: A series of derivatives of 5,6-dehydronorcantharidin was transferred into their corresponding 5,6-epoxynorcantharidin derivatives with Oxone, and finally 14 new compounds have been synthesized; and we also discover the novel combinatorial system NCS-DMSO to make N-aromatic substituted norcantharidin amic acids to their corresponding imides in high yields.

利用十分廉价的Oxone为氧化剂，成功的得到了14个5，6-环氧去甲斑蝥素系列衍生物；同时我们意外地发现了NCS-DMSO组合体系可以使去氢去甲斑蝥素酰胺类化合物实现分子内脱水而生成亚胺类化合物，首次发现和运用该全新的组合体系实现了该类反应。

The measure principles and optical paths of multi-line spectrum analysis,multi-channel radiation pyrometer,and laser speckle photography were introduced.

综述了几种电弧等离子体温度场的诊断技术，阐述了光谱多线解析法、多通道辐射高温计法、散斑照相法的测量原理和光路设计，分析比较了光谱多线解析法、多通道辐射高温计法、散斑照相法等方法的优缺点。

In the subsequent experiments, when the LaBe cathode emitted continuously and the current is 40uA, the minimum diameter of electron-beam spot recorded was 22 um. While the LaB6 emitted pulse, the minimum diameter of the focus decreased and wasnt more than 15um. The reason is that the heat accumulated on the foil-film, which enlarged the focus dimension, reduced remarkably.

当阴极采取连续发射电子的工作模式(发射电流40μA)时，记录测量到的最小电子束焦斑直径不大于22μm；而在相同条件下，以脉冲方式发射电子束时，其焦斑直径不大于15μm，原因是短时间的电子轰击减小了靶面的热堆积效应等。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
