Contrasted with the activity of the same reaction in oil-water double phased system, the hydrolyzing behavior of Camlicla Lipolytica Lipase in reversed micellar systems is much like that in oil-water double phased system. The stability and catalyzing activity are both enhanced and give rise to "superactivity". except in reverse micelles composed of cationic surfactant.

Since the element sulfur has lower electro-negativity than oxygen and the C=S double bond is easier to be polarized than C=O double bond, thiocarbonyl compounds and carbonyl compounds have different reaction properties, and their photochemical reaction mechanisms often possess dramatic difference.

但是，由于硫元素较低的电负性和C=S双键较高的可极化性，硫代羰基化合物和羰基化合物有着本质不同的反应特性，光化学反应机理常常存在着戏剧性的差别。

Based on the analysis of bistatic SAR geometry model, bistatic SAR echoed signal is modeled in the double range variables domain in this paper, and the relationship between the double range variable domain and the single range variable domain is established. Then a range-dependent Doppler algorithm for imaging processing airborne bistatic SAR raw data of the translationally invariant configuration is derived, and the effect of error of the algorithm is analyzed by simulating.

摘要该文通过对机载双基地SAR非移变几何模型的分析，建立了双距离变量域的回波信号模型，由于回波数据是在距离和域，该文推导了距离和变量与双距离变量的转换关系，解决了该模型向距离和变量域转换的问题；提出了适用于非移变模式的变多普勒参数的双基地RD算法，并对该算法中引入变多普勒斜率所存在的误差进行了仿真分析。

Secondly,proposed an new scheme that the double population genetic algorithm used the self-adaptable crossover operator and mutation operator according to the shortage of early convergence and stagnation in the traditional double population genetic algorithm based on unconvertible rate of crossover operator and mutation operator.

摘 要：介绍了图像关联规则的相关概念，描述了传统的双种群遗传算法的执行过程；针对采用固定染色体交叉概率和染色体变异概率容易出现早熟、收敛速度较慢等问题，设计出了能自适应调整的染色体交叉算子和变异算子。

Single or double-acting,three position double-actingdouble direction location,auto resetetc,on which relief valva and pressurelimiting valves may be added,on each port to restrictpressure in the port and avoid the damage caused by higher impact pressure to the system..

该阀的每一工作阀片可分为三位单、双作用；三位双作用双向定位、自动复位等不同功能，可加装安全阀，并可在每一个工作油口加装过载阀，限制该油口压力及防止冲击压力过高对系统引起的损坏。

Tobacco mosaic virus, a member of alphavirus-like superfamily, the N-terminal truncated TMV helicase formed hexamer and exhibited double strand RNA unwinding activity. Accordingly, we also constructed the same N-terminal truncated BaMV helicase-like domain and analysis the capability to unwind double-strand RNA.

在同属於alphavirus-like superfamily的Tobacco mosaic virus之解螺旋蛋白的分析中，其N端的截断蛋白会形成六聚体，而且具有解旋活性，因此我们同样建构了许多类解螺旋酵素N端的截断蛋白，测试其蛋白质的聚集形式及解旋活性。

Q2 L5 ^' f* G Wang had been outstanding in the past couple of months. Since the start of July, he was 6-1 with a 2.76 ERA in seven starts. But Wednesday night's outing was ugly from the start, as the first four Blue Jays hitters picked up hits. Matt Stairs led off with a double to right-centerfield, Lyle Overbay singled to leftfield, Alex Rios hit a two-run double to right-centerfield and Vernon Wells hit an RBI single up the middle.

y4 F* K7 d6 '0 }：|王建民加油站王小民在过去2个月以来表现优异，由7月份开始算起，他过去的7次先发拿下6胜1负、自责分率2.76的成绩，但在星期3晚上的出赛中，他从一开始就很难堪，因为前4名蓝鸟打者都敲出安打，第1棒Matt Stairs就打出中右外野2垒安打，Lyle Overbay 打出左外野1垒安打，Alex Rios打出中右外野2分打点的2垒安打，Vernon Wells打出中外野1分打点的1垒安打。
