第二次内阁会议后，奥巴马对记者说有关专家们也不确定猪流感是否比普通的季节性流感更严重，但因为是新的病毒才要引起足够关注，人们还没有对抗的免疫力。

Multinitroazetidines have been a kind of important new high density energetic materials because of the high strain energy associated with their four-membered ring and can be used constituents of high energy explosive, propellant and gun power.

多硝基氮杂环丁烷因其紧凑张力的四元杂环结构使该类化合物具有很高的能量，从而成为一类重要的高能量密度材料，可作为高能炸药、推进剂和炮用发射药的组成成分。

In the nonlinear theory the deformation tensor can be expressed as the product of two tensors, one corresponding to a rotation and the other to strain, applied sequentially.

非线性理论中，形变张量表示为与旋转相对应的张量及与应变相对应的张量的乘积。

Our study rules out the effect of strain and composition alloying as the main factor of peak splitting. We attributed it to the existence of large amount of non-stoichiometry part in GaN/Si grown by MBE. A direct proof has been observed by HRTEM, which shows that the propagation of dislocations in the underlying layers could be blocked by using periodic AlN/GaN structure.

用三轴晶高分辨X射线衍射研究了Si(111)上生长的GaN中的应变组分问题，我们发现GaN的对称（0002）及非对称（10-12）峰在三轴晶配置下的ω-2θ扫描曲线都会发生劈裂，我们排除了应力和合金化的因素，认为在MBE方法生长的Si（111）上GaN外延层中存在一个占较大比例的稍微偏离化学配比的部分。

The crack and stress-strain of Chinese White Poplar were studied by the box counting method. The results showed that the cracks were obvious fractal and that the value of dimension D was determined to be between 1.2～1.5 by studying the crack propagation in the two dimensions. By comparing the crack propagation over a period of time, we found that the value of D increased as the crack increased.

运用数盒子法对裂纹发育带在二维平面内的分布进行了分形特征研究，发现木材裂纹具有明显的分形规律，分形维数为1.2～1.5；通过比较不同时间段的裂纹发育情况，发现裂纹的分形维数随着裂纹的扩展呈增加的趋势。

Based on the conformational analysis of diphenylacetylene, which can be viewed as the structural unit of PAMs, a new method for analyzing ring strain energy is proposed and used to analyzing the ring stain energy and the structural characteristics of the PAMs.

基于对大环分子构单元二苯乙炔分子的构象分析，提出了一种新的环张力能分析方法，并且用这种方法分析了分子环张力特性和几何结构特性。

The relationship between the breakage volumetric strain and the relative breakage can be fitted by a power function.

破碎体应变和破碎率之间存在近似的幂函数关系。

Test results have shown that larger plastic volumetric strain as well as higher growth rate of pore water pressure would be generated in multi-directional shearing than in a single-directional one. Lower resistance of sand to liquefaction was also observed under the rotation of principal stress orientation.

与单向剪切相比，多向剪切会产生额外的塑性体积应变，在不排水条件下孔隙水压力增长的速率较高，特别是在具有主应力轴连续旋转特点的加载条件下，砂土抵抗液化的能力也将更低。
