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.

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.

它的特点是：水室呈倾斜立方体形状，有利于冷却水流在管板面上均匀分布；由于采用对分制，管束相应地分为左、右对称的两组，并且管束设有八块支撑隔板，每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离，以使冷却管呈拱形状；对分制的两路冷却水以相反方向流过凝汽器，从而改善管束的热负荷分布；在凝汽器喉部布置了末级低压加热器，抽汽管道及旁路排汽接受装置等。

To the materials , there are rare dislocations in their crystal grains; to the unstrengthened samples, there are many dislocations which well-distributed in their grains; and to the strengthened samples, there are a large amount of dislocations scattered along their grain-boundaries, that is, the dislocations form a dislocation wall which is of great dislocation density.

又经透射电子显微镜对各种样品微观组织结构进行分析，发现其位错组态明显不同：①原材料样品中的晶粒内仅存在有非常稀疏的位错线；②未经过强化的样品中可观察到大量均匀分布的位错，分布密度相对较高；③在经过低载锻炼强化的样品中，可观察到大量的晶粒内在晶界附近聚集着一道密度很高的位错墙。

结果表明渗透过程直接影响树脂分布，从而影响纺织品的机械性质；足够的渗透是获得良好弹性所必要的，但是为达到树脂均匀分布而过分的渗透则是不必要的，强力损失曲线有一个最大值，这是实际生产中应设法避开的。

The Ce in graphite is slightly higher than in neighboured matrix in most cases. With the same Ce content, more is alloyed in cast iron in comparison with steel.

在假定照明光源是均匀分布的小圆形光源和狭缝为一矩形的条件下，分别利用几何光学和傅立叶光学给出不同屈光度下光强分布情况。

The signals during transformer impulse test are considered to be evolving in time, also is non-stationary signals, so we can design a software algorithm for noise reduction based on discrete Gabor transform, and the basic principle is: The Gabor coefficients of Effective signals during transformer impulse test is centralized in the time frequency range, and the peak-to-peak value is big, whereas the noise Gabor coefficient distribute in the entire time frequency range equally, the peak-to-peak value is small, we can realize the desired signal and the noise separated through frequency mask function.

考虑到冲击试验中的信号都是时变信号，也就是非平稳信号，因此设计了一种基于离散GABOR变换的软件滤波算法对冲击信号进行滤波，其滤波理论依据是：有效信号的Gabor系数在时频域分布比较集中，幅值比较大，噪声的Gabor系数均匀分布于整个时频域，幅值较小，通过构造时频掩模函数来实现有效信号与噪声的分离。
