But, such a vectorization will bring three potential problems at least:① Some implicit structural or contextual information may be corrupted;②the higher the dimension of input pattern, the more space are needed for storing weight vector;③When the dimension of pattern is very high and the sample size is small, linear classifier tends to be overstrained.

但如此至少会带来3个不足：①原有矩阵模式的空间或结构信息可能会遭到破坏；②由于权向量的维数等于输入模式的维数，当输入模式维数很大时，权值的存储空间相应地会很大；③对于大维数的模式，当样本数不多时，利用线性分类器易导致过拟合。

This oxide layer could act as a dense passivating film and prevent destroying of graphite structure.

另外，氧化时形成的氧化物层与石墨结合得比较紧，可作为致密的钝化膜，并防止石墨结构的破坏。

This process leads to quick failure of the structure of the cement pastes.

而在80℃条件下，硫铝酸盐水泥石的结构是稳定的，未出现DEF破坏。

Compared with the temperature of 15℃, the results showed that the RWC and the CAT activity decreased significantly, MDA and PRO content increased obviously under high temperatur,then cell membrane-lipid peroxided,membrane structure be destroyed,physiologic function disordered and resistance decreased,these were main reasons of tall fescue oversummering hard and get ill easily.

结果表明：在高温下，以15℃为对照， RWC含量和CAT活性明显下降， MDA和Pro含量明显增加，导致细胞膜脂过氧化，膜结构被破坏，生理功能紊乱，抗性下降，这是其越夏困难、易发病的主要原因。

Based on the knowledge and results gained from detail researches, select some a roadway as trial area to study further and validate the structural rheology and to search the sound countermeasure. The trial roadway, 50 m long, is portended that very large deformation and serious damage will happen, so its stability is very poor and its support very difficult.

基于围岩结构性流变的认识，在金川二矿区1198分段，选择了变形破坏严重、支护难度较大的巷道作为试验巷道(50m)，以进一步研究高应力区结构流变围岩及其工程对策。

Swelling rust pulverizes concrete further.

锈迹的增大会进一步破坏混凝土结构。

This method quantifies and controls damage in a direct and transparent manner much better than any of the existing methods of structural design.

这个方法较任何一个现存的结构设计方法来说可以更好的以一种直接的明确的的方式确定和控制破坏的数量。

SODs play a central role in protecting cells against the toxic effects of reactive oxygen species generated during normal cellular metabolic activity or as a result of various environmental stresses.

植物正常代谢过程和在各种环境胁迫下均能产生活性氧和自由基，活性氧和自由基的积累引起细胞结构和功能的破坏。

According to the comparison analysis for the force-displacement relationship obtained from stets of earthquake simulation tests for 3 RC single story structures and the quasi-static test for one RC single story structure (identical with the former 3 models), as well as the analyses for the natural frequency change of the 3 RC single story structures with the increase of the excitation levels, it is found that the accumulated hysteretic energy-dissipation capacity is critical for the structural safety even after serious damage.

本文首先通过对近场破坏性地震动的特性分析，给出了脉冲型地震动的量化定义，并通过研究归一化反应谱变化规律的方法，分析了两类脉冲组合即：波前脉冲组合以及波后脉冲组合对于主脉冲作用效应的影响，总结归纳出波前脉冲与波后脉冲对主脉冲作用效应的不同贡献规律，并通过单层钢结构模型的地震模拟振动台试验验证了理论分析结果，为进一步研究揭示脉冲型地震动中主脉冲的破坏能力奠定了基础。
