The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。

河南省栾川县南泥湖钼矿田是我国位居世界前列的超大型钼矿田之一，通过对矿田内三个超大型矿床的矿床地质、矿体地质及成矿物质赋存状态的分析研究，揭示出钼的成矿物质来源和成矿机理，从而为进一步寻找同类型的钼矿资源提供了一系列实物资料。

Pervaporation is one of the most active areas in membrane research. It has particular advantages in separating liquid mixtures, especially removal of trace material as well as azeotropic mixture.

渗透汽化是膜科学研究中最活跃的领域之一，在分离液体混合物，尤其是痕量、微量物质的移除，近、共沸物质的分离等方面有独特优势。

Even more, since it has the active substance of natural berbal medicine, whiceh can permeate into the conified layer of skin, it can clean the detrimental substances, and kill the bacteric and virus.

它含有昆达---2号生物淬取液和名贵香料、维生素、天然保湿分子、蜂王浆等多种营养成份，使其不仅具有气味清新、泡沫丰富、润肤养颜等特点，更因其含有天然药用植物的活性物质，可深入人体皮肤角质层，清除有害物质，杀灭病菌，对由真菌引起的脚气、湿疹、体等皮肤病具有奇特的治疗效果。

Subucultures of this mould were made and experiments conducted with a view of ascertaining something of the properties of the bacteriolytic substance which had evidently been formed in the mould culture and which had diffused into the surrounding medium.

形成了这种霉菌的子培养，而且实验在这种发现溶菌性物质的观点指引下进行，那是有证据表明，这种物质是由培养的霉菌形成并释放到周围环境中。

Barish, a physicist at the California Institute of Technology, explained that dark matter is a unique kind of matter – stuff – believed to make up a significant portion of the universe.

他认为暗物质是一种很独特的物质材料，在宇宙中占很大比重。

In the process of root cutting, the root accumulated a lot of soluble sugar and soluble protein, which provided material and energy for the cell differentiation. As root differentiating, soluable protein was continuously used up. During 10 to 20 days, the content of soluble sugar and soluble protein in the basipetal top and end of rootkept comparatively stable, then declined as adventitious buds and roots growing. 40 days later, they kept invariable, because the newly formed bud can photosynthesize and the newly formed root can absorb nutrient from outside. The dynamic balances of endogenous hormone regulate adventitious buds and roots of the root. During callus growing and adventitious bud differentiating.

上部根段在细胞分化前期积累了大量的可溶性糖，为后期的分化提供能源物质，同时积累了大量的可溶性蛋白质，为愈伤组织的产生提供能源，而后随着分化，可溶性蛋白质不断被消耗。10～20d根段上部及下部的可溶性糖、可溶性蛋白质含量保持在相对稳定的水平变化不大，后期随着不定芽及不定根的生长下降较快。40d后，新形成的芽已经能够进行光合作用，新形成的根也可从外界吸收营养物质，可溶性糖、可溶性蛋白质含量基本保持不变。

The research indicate that the aquatic ecosystem of Wuhan city lakes now is: elementary production and consumption keep high amount, and accumulate in the water bodies, then the benthon ,so much as fish's community to decline seriously, cause the main nutrients cycle and energy circulation in the system is obstructed, that means the "elementary production-elementary consumption-advanced consumption" replaced by the "elementary production-elementary consumption-analyze by itself – reproduction", this circulation of the the nutrients is unfavorable to the system.

生态系统结构研究表明武汉市湖泊水生生态系统目前所处状态：初级生产和初级消费维持较高生产量和现存量，在水体中积累，而较高层次的底栖生物乃致鱼类群落严重衰退，导致系统中主要物质和能量循环：初级生产—初级消费—高级消费受阻，代之而起的是初级生产、初级消费—自行分解—再生产的循环，不利于系统中物质转移。

Four adduct compounds are found for the former, and three are found for the latter. This indicates the DNA adduct formation capabilities both of 2-chloro benzamide and the photoproduct sample. Meanwhile the result of Ames experiments of them is positive. Thus we should pay more attention to important meaning of these results since the compound, which can produce adducts with DNA, may possibly be tumorigen or even carcinogen and mutagen.

结果表明，前者与DNA反应形成四个可辨认的加合物斑点，后者与DNA反应形成三个可辨认的加合物斑点，能与DNA加合的物质为潜在的&三致&物质，同时，二者的Ames试验结果显阳性这应当引起人们对灭幼脲环境安全性的重视。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
