We make superphosphate by react rock phosphate with sulphuric acid.

我们使磷酸盐岩同硫酸发生化学反应制造过磷酸钙。

It includes the following steps: polymerizing 2, 4-dihydroxyl metaphenylene diamine hydrochloride, diamine monomer and dipic acid anhydride to gain the polyimide that contains hydroxy on the molecule chain, making the hydroxyl take esterification reacting with acyl chloride and acrylic acid to gain polyimide photosensitive material that has negative photonasty.

该聚酰亚胺光敏材料以2，4-二羟基间苯二胺盐酸盐，二胺单体和二酸酐为原料进行聚合，得到分子链上含羟基的聚酰亚胺，然后使羟基与丙烯酸及其衍生物的酰氯发生酯化反应，得到具有负性感光性能的聚酰亚胺光敏材料。

If this happens to you, you should consult your physician so that they can monitor your pregnancy.

如果发生这种情况，您应该咨询您的医生，使他们可以监控您的怀孕。

Donor bacteria, through its pilus bacteria with receptors contact, the former transmission of different length single strand of DNA to the latter, and in the latter cells for double-stranded or further nuclear chromosome in exchange, integration, so that the latter was the donor of the genetic traits phenomenon.

供体菌通过其性菌毛与受体菌相接触，前者传递不同长度的单链DNA给后者，并在后者细胞中进行双链化或进一步与核染色体发生交换、整合，从而使后者获得供体菌的遗传性状的现象。

Another internal e-mail, written a few weeks after the disaster, plaintively notes:"It's a shame what had to happen to get us to where we recommended we go several years back."

在事故发生的几周之后，另一封公司内部e-mail悲哀地提到："这使我们回到几年前我们推荐去的地方，真是个耻辱。"

Ability of a substance to rotate the plane of polarization of a beam of light passed through it, either as crystals or in solution .

物质使一束穿过它的光线的偏振平面发生旋转的能力，一如在晶体或溶液中。

An expert on Netherlands flora, De Vries showed that turgor pressure of the fluid in plant cells was partially responsible for growth and coined the term ' plasmolysis ' for the effect on cells of water loss during wilting.

作为研究荷兰植物群的一位专家。他发现植物细胞中液体的膨胀压力在细胞由于缺水而萎蔫时可以使细胞发生质壁分离。

The influences of INA on ovule ultrastructure were also researched. The plasmolysis phenomenon occurred in the nucellar cells, a great deal of bubble structures existed in the cytoplasm, the sterility of plastosome was disarranged or the structure was entirely damaged and turned transparent.

INA细菌对胚珠的超微结构的影响表现为：使珠心细胞发生质壁分离现象，细胞质中存在大量泡状结构，线粒体的嵴紊乱或结构完全被破坏，呈透明状。

A mysteriou***plosion at the mine two years ago brought simmering tensions in to the open.

二年前，这个矿发生了一次神秘的爆炸，爆炸使空中充满了不安和紧张。

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

以煤、油、气共生的辽河盆地东部凹陷和我国首次在矿井中发现、研究、开发煤层气藏的阜新盆地王营井田为例，系统地阐述了火山活动在古近系沙河街组三段对褐煤、长焰煤和气煤在平面及垂向分布的控制，进而导致各赋煤区气源条件的不同；估算了王营井田在区域深成变质过程释放甲烷气的基础上，接触变质作用所形成的附加甲烷量；指出由于岩浆侵入形成了天然焦和高变质裂隙煤，使煤层物理性质及储集能力发生了大的变化；强调了岩墙等不同产状的岩浆侵入岩体对煤层气的封闭作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
