天然的状态

Keeping an enzyme in its native form with high catalytic activity is of great significance.

保持酶的天然状态和高催化特性具有重要的意义。

From dissolved gas model, combined with measured data of reserviors, method for calculation of the beginning degasification of dissolved gas in oil is derived and typical degasification model is constructed.

认为济阳坳陷油溶解气的起始脱气深度大约在1 700～2 000 m之间，埋深小于起始脱气深度，可形成气层气、气顶气和夹层气天然气藏；埋深在起始脱气深度至3 900 m之间，气藏在油中处于欠饱和状态，以溶解气赋存形式为主；深度大于3 900 m，烃源岩才开始进入大量游离气生成阶段，可形成深层原生气藏。

The domains Ca2 and Ca3 are responsible for the dimerization of a-heay chains in immunoglobulin A molecules under natural conditions.

在天然状态下，IgA分子的Ca2和Ca3结构域负责重链的二聚体化。

The flow on natural slope land is a kind of compound flow whose velocity takes a direct ratio with water depth.

天然坡地水流是一种混合状态的水流，其流速与水深成正比。

The experimental results show that: lithium is scatteredly precipitated as natural lithium carbonate in the whole evaporation process, and the highest content of natural lithium carbonate in solid phase is 2.0%, so it is difficult to get the mixed salt with high-grade lithium carbonate; boron is precipitated as borax in the whole evaporation process, and borax is precipitated in large quantity with the highest content of 15.64% in solid phase until the brine is extremely concentrated (CWR≥97.9%) and intergrows closely with typical cold-phase natron; potassium is precipitated as sylvite and aphthitalite in the whole evaporation process with a content from 9.49% to 34.44%.

结果表明：在低温蒸发状态下，锂以天然碳酸锂形式在整个蒸发过程中分散沉淀，固相最高含量仅达2.0%，因此难以获得较高品位的富锂混盐；硼在全蒸发过程中以硼砂形式自然沉淀。当卤水高度浓缩（蒸失率达97.9%以上）时大量析出并与典型冷相矿物泡碱紧密共生，固相中硼砂含量最高可达15.64%；钾以氯化钾和钾芒硝形式沉淀，在蒸发浓缩的全过程中均有不同程度析出，固相含量在9.49%~34.44%之间波动。

Native molecular mass of Vg in the Bombyx mandarina is around 440kD through Native-PAGE of egg substracts of the two silkworms.

通过Native-PAGE分析推定了野桑蚕卵黄原蛋白在天然状态下的分子量约为440kD。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
