The analyses of electronic structures shows that the catalytic reactivities for H2 adsorption of the different surfaces are dependent on the numbers of s orbital bonding electrons around Fermi level for the uppermost layer metal atoms which interact directly with H2. It is easy to form vacancy for hydrogen atoms next to iron atom, which indicates that hydrogen atom cannot be escaped, but it is difficult to from vacancy for hydrogen atoms next to magnesium atom, which indicates that hydrogen atom can be escaped. Hence it is thought that the change of dehydrogenating properties of MgH2 with or without a little iron addition attributes to the weakened bonding between magnesium and hydrogen.

分析电子结构发现：空位缺陷有助H2吸附于Mg表面，与Mg(0001)表面最上层与H2直接产生吸附作用的金属原子在费米能级附近s轨道的成键电子数密切相关；在Fe合金化MgH2体系中，与合金化元素Fe近邻的H原子形成空位的难度增加，H原子较难释放；与Mg近邻的H原子形成空位的难度减少，H原子容易释放；Fe合金化导致Mg-H之间存在较弱的成键作用，因此，MgH2体系的解氢性能得到提高。

Of all the passions, however, which are so extravagantly disproportioned to the value of their objects, love isthe only one that appears, even to the weakest minds, to have any thing in it that is either graceful or

Besides various interferences, the wave front diffusion, the ground absorption and the attenuation are all the causes of a weak seismic reflection and, plus the complicated superficial geologic setting and the reservoir bed features of low amplitude, low porosity and low permeability of the compacted thin detrital rock in HJQ, the conventional seismic amplitude fidelities do not meet the criteria of the seismic inversion.

除各种干扰外，地震波传播过程中的波前扩散、大地吸收、衰减等使地震反射能量变弱，加之杭锦旗地区复杂的表层地质条件和低幅、低孔、低渗致密性薄层碎屑岩的储层特点，使常规保幅地震资料离地震反演的要求还有差距，并且反演技术本身不具备噪音识别功能，包含噪音的反演必然会影响地质效果。

The giant haloes developed in these nuclei are due to the pair correlation and the contribution from the continuum such as 3〓 orbit.

分析表明，Ca中的巨晕现象是由于处于弱束缚轨道的中子对被散射到3〓等连续态而形成的。

We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.

本研究针对昆虫运动的特点，研究开发了测量昆虫运动，特别是自由飞行昆虫运动的光学方法，包括：风洞中扇翅力的测量，解决高灵敏度光学测量的抗干扰问题；帧头帧尾流场测量方法，解决由CCD拍摄帧频导致的测量速度低的问题；调制相关算法，解决透明翅膀上散射光较弱问题；梳状条纹投影法，解决翅膀弓形变形测量问题，不需要以往的翅膀刚性平板或刚性条杆假设；多参数的综合测量，解决各参数间的相位匹配问题。

According to the results of structure analysis by GPC,ESR and NMR spectroscopy,when the temperature is above 80℃,the AMS-GMA and AMS-AMS weak bonds are first scissored into two macroradicals.

TG、GPC、ESR和NMR等表征结果证明，当温度高于80℃时，共聚物poly中较弱的AMS-GMA和AMS-AMS键断开，从而形成两个链自由基，随之发生β-剪切和夺氢反应，最终生成AMS和GMA单体。
