前者的

The experiments of bioprocess intensification principle, SCP principle, lay in two levels, multi bioreactions and single bioreaction.

以SCP理论体系看纤维素制酒精的SCP系统，则后者是前者在多个反应层次（含生物反应与生化反应等）上，进行工程实践的实施例，是以工艺开发为主的实践。

These two kinds of consenescence have the distinction of in principle, former it is normal, in everybody the metropolis on the body happens, and latter is unusual.

这两种衰老有原则上的区别，前者是正常的，在每个人身上都会发生，而后者是异常的。

The former stimulates the cells and transfer the signals into the cells through the ligation with receptors on the cell membrane. The latter, a derivative of nucleotide, causes a cytotoxic effect to suppress thymidylate synthetase activity, and, therefore, to damnify RNA and DNA synthesis.

前者通过与细胞表面的受体结合，把胞外刺激传递到胞内，诱导免疫受体介导的信号级联放大作用，引起一系列免疫效应；后者是是小分子的核苷酸衍生物，可直接进入细胞内，通过抑制胸苷酸合成酶及损伤RNA、DNA等对基因转录和核苷酸代谢产生影响，最后产生细胞毒效应。

By the partial purification of Arthrobacter nicotinovorus D-97 endocellular enzymes and the results of enzymatic reaction of enzymes of partition collection, it was found that enzymes related to trehalose synthesis were consisted of Trehalose-forming Enzyme and Trehalose-releasing Enzyme . Trehalose-forming Enzyme could convert maltooligosaccharides into non-reducing maltooligosyl trehalose by intramolecular transglycosylation, and Trehalose-releasing Enzyme could hydrolyze α-1, 4 linkage between the trehalose residue and the maltooligosaccharide residue to release trehalose and maltooligosaccharides with two glucose monomer lesser.

将食尼古丁节杆菌D-97胞内酶部分纯化并对各收集组分进行酶反应，发现其海藻糖合成酶系由海藻糖生成酶(Trehalose-forming Enzyme，TFE)和海藻糖释放酶(Trehalose-releasingEnzyme，TRE)组成，前者分子内转糖基将直链麦芽寡糖转化为没有还原性的麦芽寡糖基海藻糖，后者专一切割麦芽寡糖基海藻糖分子上麦芽寡糖基与海藻糖连接的α-1，4糖苷键，从而释放出海藻糖和减少了两个葡萄糖单体的麦芽寡糖。

Phorias are sometimes called latent strabismus , yet there is a fundamental difference between eyes which drift when fusion is artificially eliminated , and eyes which remain crossed because fusional reflexes never developed.

6隐斜视被称为潜在的显斜视，两者本质上的不同，在于前者由于人为消除融像时发生眼位偏斜，而后者停留在惯常的偏斜眼位上，因为融像反射永久失去。

He also wrote a string of worthier books on places—country houses,Inigo Jones, the Tudor renaissance, Venice, Rome and StPeter's—and on an eclectic range of British personalities.

其实他写得更好的是一系列建筑史传和形形色色的英国名人传。前者包括乡村宅邸， Inigo Jones 建筑，都铎建筑，维也纳、罗马建筑，和一部罗马圣彼得大教堂的专著。

To achive the same expanded area of skin compared with several smaller expanders, a larger tissue expander costs less time, appears a lower intracapsular pressure, needs less volume of water filling, reduces the number of injection pots and has a mild trauma and a lower risk of infection.

使用较大容积的扩张器与使用多个小扩张器，达到同样的扩张面积，前者所需时间短、囊内压低、注水量少，并能减轻创伤、减少感染和注射壶的数量。

The photodisruption of tissues produced by the Q-switched Nd: YAG laser produces a quicker more efficient iridotomy than the thermal effect of the argon laser with more tendency to iris hemorrhage.

一、我们所用的Q开关Nd：YAG激光器与氩激光器的治疗作用机理不同，前者是利用其强大的电磁辐射产生光裂效应，对组织造成机械性损伤，而后者则是利用其组织热凝固效应进行治疗。

In the rabbits, every Nd: YAG laser iridotomy smaller than 200μm and argon laser iridotomy, Nd: YAG laser combined with argon laser iridoto- my smaller than 450μm closed by the first postoperative week. The mecha- nism for iridotomy closure was assumed to be iris pigment epithelial prolifera- tion, migration and the reformation of stromal connective tissue once the pos- terior pigmented cells have initially bridged the iridotomy.

四、兔眼虹膜激光损伤后的修复能力较强，小于200μm的Nd：YAG激光孔及小于450μm的氩激光、Nd：YAG激光联合氩激光孔均在术后1周内关闭，前者以基质胶原结缔组织再生较明显，而后者以色素上皮增殖、迁移为著。

The formation of a lithological reservoir is the result of mutual action of reservoir forming power and reservoir forming resistance.

岩性油气藏的形成是成藏动力与成藏阻力共同作用的结果，只有在前者大于后者的条件被满足时才可能成藏。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
