查询词典 process

Third, most magnesium alcoholates are prepared by alcoholysis.The process is based on the exchange of alkoxide groups of a metal alcoholate in the presence of an alcohol other than the alcohol corresponding to the original alkoxide,i.e.on the alcoho- lysis of a metal alkoxide with a different alcohol. Primary alcoholates can be prepare- d by this process,such as magnesium di-n-propanolate,magnesium di-n-butanolate,m- agnesium di-isobutanolate.

该方法适用于较高沸点的伯醇的醇镁化合物，例如正丙醇镁、正丁醇镁、异丁醇镁等，但是用醇解法制备出的叔丁醇镁，其纯度只有80％，这是由于叔丁醇具有较大的空间位阻效应，阻碍了醇交换的进一步进行，并且叔丁醇沸点与甲醇相差不大，使得甲醇难以快速蒸出，只能得到一种混合醇盐产物。

Alcoholysis of urea is considered to be a novel and promising process in synthesis propylene carbonate, and the transesterification process to synthesize diphenyl carbonate is also payed much attention.

尿素醇解法合成碳酸丙烯酯是目前较为新颖和有前途的合成方法，而酯交换法合成碳酸二苯酯一值受到人们的关注。

This process is actually the process of algebraic extension; also it is the basic way of algebra: organizing some objects into an operation system, and then study the relationship between elements or parts of the system.

这实际上是代数扩张的做法，也是代数的本质：将一些对象组织成一个运算体系，研究这个体系中各个个体之间以及部分与全体之间的关系。

For ALIF, this ranged from 0.8 (complete, 100% fusion) to 3.3 (solid fusion of the posterior 25% disc space). For PLIF, the numbers were more aried, ranging from 0.7 (complete, 100% fusion) to 6.9 (solid fusion of posterior 25% disc space with bilateral facetectomy). For intertranserse process fusion, the least motion was with a solid bilateral fusion, with medial healing to the pars (2.0); the greatest motion was found with a solid unilateral fusion without medial healing (6.0). Interspinous process fusion allowed only 1.9 of motion.

前路椎间融合，范围是0.8度（完全、100%融合）到3.3度（后方椎间隙25%的稳定融合）；后路椎间融合范围较大，是0.7度（完全、100%融合）到6.9度（伴有双侧峡部近内侧融合的后方椎间隙25%的稳定融合）；横突间植骨融合，最小值2.0度是双侧偏内侧稳定融合，最大值6.0度是单侧且不偏向内侧融合；椎板棘突间植骨融合只出现1.9度的活动度。

Study on the Crystallization Process of Labeled GL-7-ACA Acylase CA130 Complex 7β-bromoacetyl amino cephalosporanic acid (BA-7-ACA), an analog of glutaryl-7-amino cephalosporanic acid (GL-7-ACA), can inhibit and specifically alkylate GL-7-ACA acylase (CA130) from Pseudomonas sp. 130, forming a carbon-carbon bond between BA-7-ACA and the C-2 on indole ring of Trp-β4 residue of CA130.Here we reported that BA-7-ACA labeled CA130 (BA-C130) could self-catalyze the hydrolysis of BA-7-ACA during crystallization process. The hydrolysis was confirmed to be a reaction analogous to the one of GL-7-ACA by comparative MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) spectrometry analysis.

二、GL-7-AcA酰化酶CA130标记复合物的结晶过程研究溴乙酰氨基头孢烷酸（7β-bromoacetyl amino cephalosporanic acid，BA-7-ACA）作为戊二酰-7-氨基头孢烷酸（GL-7-ACA）的类似物，不仅能够抑制GL-7-ACA酰化酶CA130的活力，而且能通过在BA-7-ACA和CA130的β亚基第四位色氨酸吲哚环二位碳原子之间形成碳-碳共价键而将CA130特异的烷基化。
