The current taxonomic status of the Clemmys complex of freshwater turtles places the Old World genera Mauremys and Sacalia in the Geoemydidae and the New World genus Clemmys in the Emydinae. These three genera were previously considered to be congeneric.

水龟组由旧大陆潮龟科的拟水龟属、眼斑龟属和新大陆龟科的水龟属组成，这三个属以前一直被认为是同属的，但没有得到形态学和染色体等方面的认同。

In this paper, we analyzed the larch extract tannin, aminom ethylation of larch extract tannin, quaternization of cationic larch extract tannin and amphoteric larch extract tannin (sulfonation of the larch extract tannin quaternary ammonium) by infrared spectral analysis, confirmed the quarternization and sulfonate groups, and measured its water treatment properties such as flocculation, scale inhibition, results showed that quaternization of larch extract tannin and amphoteric larch extract tannin have better water treatment ability, can realize the multifunction.

本论文采用红外光谱法对落叶松单宁、胺甲基化落叶松单宁、阳离子落叶松单宁季胺盐、两性落叶松单宁进行了化学结构分析，并对其水处理剂性能如絮凝、阻垢进行了检测。实验结果表明：落叶松单宁季胺盐和两性落叶松单宁均具有较佳的水处理能力，是性能良好的一剂多效工业水处理剂。

Theoretical analyses indicate that the reduction of internal relative humidity or so_called self_desiccation of HPC may be mainly caused by the increase in the mole concentration of soluble ions in HPC and the fractions of gel water, absorbed water and interlayer water in the total amount of evaporable water.

理论分析表明，混凝土中可溶离子浓度的增大，及凝胶孔水、吸附水、层间水在总可蒸发水量中的比例增大是导致HPC自收缩或自干燥的主要机理。

The results were as follows: 1. Response of physiology indices of Medicago falcata L. to drought stress is different. There are not obvious correlation among indices and ability to drought resistance. The indices include critical water saturation deficiency, free and bound water content, tissue water, peroxidase isozyme, free proline content, chlorophyll a, chlorophyll b, total chlorophyll and chlorophyll. These indices are not fitting for assessing ability of drought resistance of Medicago falcata L..

黄花苜蓿各生理指标对干旱胁迫的响应不同，临界饱和亏、自由水含量、束缚水含量、组织水含量、过氧化物同工酶、游离脯氨酸含量、叶绿素a、叶绿素b、叶绿素总量以及叶绿素与黄花苜蓿抗旱能力之间不存在明显的相关性，不适宜采用这些指标来评价或判别黄花苜蓿材料间抗旱能力的强弱。

In order to analyze the influence and damage of the top and bottom of rock mass in floor water-resisting layers due to water pressure in water bearing layer and mining pressure, this paper applies the methods of similar material simulation test and mechanical analysis of floor water invasion in the near of faultage to further comprehend the mechanism of floor water invasion.

为了分析底板含水层水压及采动矿压对底板隔水层岩体上部与下部的影响与破坏，应用了相似材料模拟试验以及断层附近底板突水的力学分析方法，对底板突水机理有了进一步的认识；同时，由断层附近底板突水的力学分析方法所得到的理论计算结果，也可以作为判别类似条件下遇断层时承压水体上采煤是否安全的依据。

Point out flet mechanism of aggregate and pitch from two respects of physics and chemical performance, probe into internal cause and external cause on road surface further.

主要内容包括：分析和归纳道路水损坏现象的特点和对道路产生的影响；对评价沥青混合料水稳性的各项指标及测定方法进行分析比较；从物理性能和化学性能两方面指出集料和沥青的粘结机理，进一步探讨路面产生水损坏的内因和外因。

Also, the study provides spatial and temporal information on the distribution patterns and compositional characteristics of modern and fossil benthic foraminiferal fauna, and their relation to the environmental variables.

发现冲绳海槽中南部冰期-冰消期的底层水流通状况较冰后期弱，说明冰期时西北太平洋中深层水的演化没有对该海区底层水团的性质产生影响。

In order to understand the formational mechanisms of water cushion flow fields of water cushion belt conveyor,the numerical simulations on water cushion flow fields were carried out.

为进一步了解水垫带式输送机水垫流体场的形成机理，对水垫流体场进行了数值仿真研究。

Must let Aquarius pursue on own initiative, is an exceptionally difficult matter, is unable in Aquarius the world to withstand denial, is such frail, regardless of on the surface looked like is the how strength Aquarius in front of the person a carefree heart liver appearance, had not always thought the others see own sadness, such can have not the secure feeling, Both does not need awkward vindicating then to be rejected, and cannot fall in love easily to be together difficultly frigidly to bid good-bye.

要让水瓶座主动去追逐，是件异常困难的事，在水瓶座的世界里无法承受拒绝，就是这么脆弱，无论表面上看来是多么的坚强。水瓶座在人前总是一幅无忧无虑没心没肝的样子，不想别人看见自己的悲伤，那样会有不安全的感觉，总是在无人的地方暗自落泪。算了，还是放在心里吧。既不用尴尬的表白然后遭到拒绝，又不会相爱容易相处难的惨烈分手。

The results showed that the effects of the oxidized starch and the glutin on solution time in the water were obvious, while the glycerin, sodium laureth sulfate and metacrylic acid ester had less influence.

实验结果表明：氧化淀粉和明胶用量对氧化淀粉改性PVA水溶性薄膜的水溶性影响非常显著，而甘油、十二烷基醚硫酸钠、甲基丙烯酸酯对水溶时间的影响较小。
