Crystallization behavior of undrawn and hot drawm PET film with random orientation in chain segments and high orientation in the global sense has been compared using SAXS and WAXD.

采用小角和广角X-散射法比较了未拉和热拉PET膜在结晶性能方面的差别，热拉试样在分子链段的小尺度范围内基本上是无规取向，而在分子链的大尺度范围内却是高度取向的。

When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。

The applicability of this constitutive model is evaluated with the simulations of material tests conducted by Sasaki et al., includes (1)Uniaxially constant strain amplitude cyclic test,(2)Fast in tension/Slow in compression constant strain amplitude cyclic test,(3)Slow-fast-slow constant strain amplitude cyclic test,(4)Cyclic strain with tensile hold time test. Simulations based on this constitutive model have a good agreement with (1),(2) and (3), proofs that it can describe the cyclic stress-strain behavior of 60Sn/40Pb solder very well.

为验证本模式之能力，本文选择Sasaki等人之实验为对象，分别对60Sn/40Pb焊锡在(1)定应变振幅之循环单轴负荷实验、(2)拉伸快/压缩慢之定应变振幅循环负荷实验、(3)慢-快-慢之定应变振幅循环负荷实验、(4)拉伸应力保持之循环应变实验下的材料行为进行模拟，由(1)、(2)及(3)之结果证明本模式对60Sn/40Pb焊锡循环应力-应变整体行为具有理想的描述能力，并对循环塑性应变范围与应力范围之值有准确的预估。

Local governments usually prefer protecting interests of influential groups in their jurisdictions but neglect voice of uninfluential groups and the damages to people out of their jurisdictions when they make and implement some policies.

当地方政府在制定与实施各项政策时，它通常会偏向于其职责范围之内的利益而忽视其职责范围之外的损害，通常会维护强势群体的利益而忽视弱势群体的呼声。

Simulative results show that the electron beam can be transported in the unmagnetized plasma-filled for two reasons. The first, the plasma neutralizes the majority of the space charge forces within the beam. The second, radial electric field generated by electron beam interaction with the plasma leads the beam to converge along axis. By PIC simulation, we find that atomic mass of the background ion effects on the Characteristics of the plasma-filled devices.

非磁化等离子体填充的RBWO-FEL的模拟表明只有在一较窄的背景等离子体密度范围内，电子注才能良好传输，产生泵波及激光功率输出，并都存在有峰值功率点，同实验观测到的结果完全吻合；该范围内，电子注的传输是由于背景离子中和了注中径向发散空间电荷力及注在等离子体中产生的径向的电场使注在轴向汇聚。
