And the soldiers, guardian, PK killed when stars are not杀杀of Kazakhstan, in addition to killing stars to flicker and then followed by a row of skills (this time the role of 5800's life played out on the full), followed by three kinds of this job is not simply rely on into my body, and魔道PK when you remember he is a gram Therefore, and魔道playing, you just made 42 of the cis and Dr. skills and drugs out of the ball, but you should never silly place to enlarge the station to retribution, and his other close千万千万千万body, his silence on you running quickly, and time is too silent, and on the skills to beat him shun fat, remember, and his other close千万千万千万, operation of the dual differential scattering approach also meters.

和战士，守护，杀星PK时都是随便杀杀的哈，除了杀星能闪烁然后接下来一排技能(这个时候5800的生命的作用就完全发挥出来了)，接下来这3种职业是根本靠不进我身的，和魔道PK时，记住他是克你的，所以和魔道打时，你只要用42的顺发技能和毒和招出来的小球，千万别傻乎乎的站原地放大地报应，千万千万千万别和他靠近身，他沉默你了就赶紧跑，等沉默时间过了，就顺发技能打他，记住千万千万千万别和他近身，操作差的偶也米办法撒。

The fluorescence properties of complexes of europium with β-diketone and terbium with benzoic acid and its derivatives were analyzed and the synergic effect of the second ligand was illustrated from the energy matching of the minimum triplet state of ligands and the resonance energy level of rare earth ions.

提出了掺杂离子荧光增强效应的机理。 4。首次采用ab initio CIS方法，在劈裂价层基组3—21G水平上对各配体进行了量化计算，系统分析了前线分子轨道特征和激发态的能级，从配体最低激发三重态能级与稀土离子共振能级的能级匹配，分析了铕与β-二酮的配合物的荧光性能和铽与苯甲酸系列衍生物的配合物的荧光性能，解释了第二配体的协同效应。

Results DNA analysis showed that almost all the CISs and EMICs were diploidy , while 90% of invasive carcinomas were aneuploidy.

结果 DNA倍体分析表明CIS、EMIC和浸润性癌不同，前两者几乎都是二倍体，而后者 90 %为异倍体

We have obtained 16 cDNA fragments binding to the elicitor response cis-element from rice cDNA expression library using yeast one-hybrid system.

利用酵母单杂交体系，我们从水稻的cDNA库中分离到16个阳性克隆。

Mutation of the gARID1 binding site in the cwp1 promoter resulted in a decrease of promoter activity and mRNA levels during vegetative growth and encystation, suggesting that the gARID1 binding sites are positive cis-acting elements of the cwp1 gene promoters in both trophozoites and encysting cells. Using cotransfection assay, we also found overexpession of gARID1 can increase luciferase activity and mRNA levels, while mutation of the gARID1 binding sites of the cwp1 promoter resulted loss of this transactivation.

我们也用萤光酵素基因接上cwp1基因启动子，如果将其cwp1启动子上的gARID1结合位置突变，也可以发现萤光酵素和讯息RNA的表现有明显的下；再用cotransfection assay，可发现gARID1会使萤光酵素和讯息RNA表现明显上升，然而如果将其cwp1启动子上的gARID1结合位置突变，这种转活化则消失。
