Yes, you have these cutesy plants, but the existence of zombies prevents it from being to sugary. Yes, it's a PopCap game with zombies, but they're goofy, cartoony zombies so it's all good.

你是有超可爱的植物，然而僵尸的存在就让游戏的"含糖量"不会太高；它也确实是有僵尸的 PopCap 游戏，然而它们是呆呆傻傻又****的僵尸，因此整体来说还不错。

For the naphthalene hydrocarbon in crude oil, strains were isolated by screening and acclimatizing at the existence of cyclohexane.

最后进行了单一菌和混合菌降解石油废水的试验研究，得到很好的效果。

In the aspects of research method, we took the method of preparing sol at first and then impregnating the wood to obtain ceramic-wood composite; this method made the wood use efficiently and increased the wood's weight gain percent. The ceramic-wood composite with performances of well decay resistance, dimensional stability, effloresce resistance and high strength was obtained by importing the cymene to the net of gel as the result of co-hydroxylation between MTES and TEOS. Making use of XPS ,we found that the apex of Si2p、O1s、C1s had evident chemical shift , which validated the existence of Si-O-C bonding.Key Words: Sol-gel, Ceramic-wood composite, Modified sol, Ecomaterials

在工艺方法上，采用先制备溶胶，然后浸注木材的工艺方法具有原料利用率高、提高增重率的优点；采用甲基三乙氧基硅烷和正硅酸乙酯共水解的方法，将甲基引入陶瓷化复合木材的凝胶内部，所制备的材料具有尺寸稳定性好、具有耐风化和耐腐朽性，强度高的特点；首次利用X射线光电子能谱，发现了Si2p、O1s和C1s谱峰发生了明显的化学位移，证实了Si－O－C键合作用的存在。

In contrast to the 2-DIGE (two-dimenaional gel electrophoresis) profile of Tsga2, existence of multiple pI variants of MSAP also displayed the difference in posttranslational regulation between the murine and cyprinid homologues.

利用MSAP的抗体侦测各种脊椎动物之可能同源蛋白证实各物种MSAP同源蛋白间的确有分子量差异的情形。

In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。

This paper stressed on the fact that electric displacement vector is a supplementary physical element,focused on a difference between D and D surface integral and on the condition of D=ε_0E_0 existence,and made a comprehensive and correct understanding for beginner.
