Adopting the model of uniform load and triangular load separately,MRFs of different story numbers and bay numbers are analyzed by static Pushover analytical method,and the global capacity envelopes are obtained.Then,through a method for establishing the inelastic demand spectrum of design intensity and rare intensity based on elastic spectrum of seismic design code for buildings,the structural target displacement of design intensity and rare intensity are estimated by improved capacity spectrum method.The corresponding structural ductility reduction factor,the overstrength factor,the structural influencing coefficient and displacement amplification factor are determined.

分别采用水平均匀分布力和倒三角分布力加载模式对不同层数和跨数的钢框架结构进行了静力推覆分析，并得到了结构的能力曲线，在此基础上，应用改进的能力谱法，以规范反应谱为基础建立设防烈度和罕遇烈度下的弹塑性需求谱，确定出结构在设防烈度和罕遇烈度下的目标位移，进而求解出结构的延性折减系数、超强系数、结构影响系数和位移放大系数等参数；同时，分析了不同加载模式、层数和跨数等对各系数的影响。

Although the frequency of removal of eye has significantly decreased over time in our country, the indications for the same suggest that there is a need of further improvement of eye care services in Malaysia.

全眼球炎和眼内肿瘤是眼球摘除术的主要手术适应证，尽管现在在我国需要行眼球摘除术的病例数量较以前有显著降低，但手术适应证比例的变化提示我们，在马来群岛眼部的护理仍需要很大的改进。

Even the age of 110 years, at which Joseph died, appears to have been regarded in Egypt - as is shown by several papyri - as the most perfect age to be desired.

即使年龄的110年，在约瑟夫死亡，似乎已经被视为在埃及-这是表现出了纸莎草纸-最完美的年龄有待改进之处。

In this thesis, FDTD method and the far field integration method are introduced and used in study of radiation characteristics of the dielectric parallelly loaded dipole antenna for pulse radiation.

本文用FDTD方法研究了脉冲天线在并联加载介质块后的辐射特性，并在共形网格算法的改进上做了一些探索。

For example, it is a pathogenic bacterium and has endotoxins; it secretes protein into the periplasm and often into inclusion bodies. Bacillus subtilis is an attractive host for the production of heterologous secretory proteins. Many genes has succeed expressed in Bacillus subtilis, and the plasmid vectors for Bacillus subtilis are now taken from other genus bacterium, such as Staphylococcus aureus or lactococcus lactis and so on. As it is clear to known that these plasmids are far from optimal for Bacillus subtilis, because of low efficiencies of cloning and high levels of replicating instability.

枯草芽胞杆菌是目前原核表达系统中分泌表达外源蛋白较理想的宿主，近几年已在枯草芽胞杆菌中成功表达了多种基因，但大多都应用来源于金黄色葡萄球菌、乳酸杆菌等的载体来表达外源基因，由于其在枯草芽胞杆菌中存在分离复制的不稳定及外源基因的克隆表达效率低的现象，故都不是枯草芽胞杆菌的最佳选择，还有待改进。

We conclude that local perivascular delivery of genetically modified aFGF results in significant improvement in myocardial flow and regional and global left ventricular function.

在重要的改进在心肌的流动和地区性和全球的左方的心室的函数我们结束遗传上地被更改了的aFGF结果的那次本地的血管周的交货。
