This theory detaches the industry into certain markets and analyzes the market structure, enterprise conduct and market performance through the actual research. By this way, the relationship between market structure, enterprise conduct and market performance can be decided and the emphasis of industry policy then came out.

该理论以实证研究为主要手段将产业分解成特定的市场，按结构、行为、绩效三个方面对产业进行分析，能够发现产业市场结构、企业市场行为和产业市场绩效的相互关系，从而确定产业政策的重心。

Specifically, the reported difficulty in dissociating the human ES/EG cell clusters into viable single cells is problematic, particularly for gene–targeting experiments.

具体来说，报告难以分离的人类胚胎干/乙二醇细胞簇成可行的单细胞是有问题的，尤其是对基因打靶试验。

At the solid-liquid reaction stage, the molten Mg promotes the reaction between Mg and residual B powders under the infilteration and enwrapping effects. Finally, the formed MgB2 grains grow up to regular hexagon morphology rapidly by Ostwald ripening mechanism.

在上述工作基础上，同样采用热分析的手段，进一步研究了原位烧结过程中纳米Al2O3粉末掺杂对多晶MgB2相形成过程的影响，并确定了该影响与超导电性之间的内在联系。

The method has such advantages as easy operation, stable process and no pollution. The product, when used for fatting leather, can improve the quality, softness and toughness of leather, and can tightly bond with leather fibers. The bonded fatting agent does not transfer in leather, and has such advantages as rapid permeation and uniform distribution, thus can make leather soft and moist.

本发明操作简便，工艺稳定，无环境污染；用本发明制备的产品对皮革进行加脂，不仅能增加成革的丰满性、柔软性、柔韧性，而且能与皮革纤维结合牢固，结合的加脂剂在皮革中不易发生迁移，还具有渗透快，分布均匀等特性，可使皮革柔软、滋润、经久而不枯板。

A DNA demethylating agent. This finding suggests that Met induce the flowering of detached cotyledon culture perhaps through acting as a methyl donor of DNA methylating not as the precursor of ethylene synthesis.

上述结果说明：10^(-5)M Met浸种3 h能显著促进子叶培养物的花芽形成，Met对离体子叶成花的诱导作用可能是作为甲基供体通过DNA甲基化途径来实现的。

Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads. At last, orientation field converges at delta point. This model can explain well why core and delta points exist in pairs in fingerprint images.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

Orientation field near baseline is parallel to baseline which is caused by baseline. Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

Its algorithm to recursively continue the source and receiver wavefields, which includes a wavenumber domain phase shift in a constant background medium followed by a phase correction in the space domain that accommodates lateral velocity variations, can tackle the effects of lateral velocity variations for imaging under complex overburdens.

其递归波场延拓算法包含波数域针对常速背景的相移处理和空间域针对横向速度扰动的相位校正，可以应对上覆地层速度横向变化对构造成像的影响。

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。
