四级的

If you compare the Hood and Scharnhorst, in Hearts of Iron 2 the Scharnhorst is the superior ship in all aspects, as it is a model 4 battle cruiser while the Hood is only a model 3battle cruiser. However with the Hearts of Iron 3 system we can do a very neat trick. The Hood is a large ship with 15'' guns and a lot of Anti-Aircraft batteries, however its design is pre-Jutland and thus it had a known vulnerability to plunging fire.

如果你比较一下胡德和沙恩霍斯特，在小胡子2代里头沙恩霍斯特在所有方面都更加先进，就像它是四级模型的战列巡洋舰而胡德仅仅是三级的，然而胡德是在日德兰海战之前设计的，因此它有一个公开的弱点那就是水平装甲过于薄弱。

Mechanism of the allosteric change Oxyhemoglobin ahs a different quaternary structure from deoxyhemoglobin. As O 2 binds to the Fe 2+ it distorts the heme group and moves the proximal histidine. This in turn moves helix F and alters the interactions between the four subunits.

变构转变的机制：脱氧血红蛋白与氧合血红蛋白有不同的四级结构，当 O 2 结合到 Fe2+时，使血红素基团变形并移动邻近的组氨酸，随之移动螺旋 F 和改变四个亚基间的相互作用。

Secondly, it discusses strenghten the ideological and political education of party member ranks in private enterprise a

目录中的二、三级标题和正文中的四级标题，以及正文中的加粗文字可以帮助读者了解本文的主要观点。

The whole system includes all software of 8 subsystems, not merely possess the complete supervision interface , have reached management expectancy of four grades in the province and city , subcenter , enterprise, and software development adopts much hierarchical structure, no matter all keep standard interface in order to increase new function or and department , bank of higher level ,etc.

整个系统包括8个子系统的全部软件，不仅具备完善的监管接口，达到了省、市、分中心、企业四级管理要求，而且软件开发采用多层次结构，无论为增加新的功能还是和上级部门、银行等都保留有标准接口，数据库数据字典、存储过程、前台程序用源代码都可以公开给客户，便于未来的功能扩充和共同维护。

The quaternary structures of aves, teleost and mammal Hbs were compared showing that the subunit distances and molecular volumes of aves and teleost Hbs are larger than mammal Hbs. Analysis indicates it is due to that the former two select residues with larger side chain.

通过对鸟类、硬骨鱼类和哺乳类血红蛋白的四级结构的比较，发现鸟类和硬骨鱼类血红蛋白亚基间的距离和分子体积大于哺乳类血红蛋白，分析表明这是由于前二者选择了较大侧链的残基。

Ike first slammed into the Turks and Caicos and the southernmost Bahamas islands as a Category 4 hurricane, but thousands rode out the storm in shelters and there was no immediate word of deaths on the low-lying islands.

艾克首先袭击了T和c，而且引发了巴哈马最南端的四级飓风，但上千人在避难点躲过一劫，并且没有对这个低洼岛国伤亡的即时的报道。
