结果表明，未添加的样品中主要检测到的是硅氧链的变化；添加5%的样品，低温检测到有四配位的钛存在，但是高温时却未检测到六配位的钛离子的吸收峰，这可能是由于生成的含钛晶相太少，红外光谱未能敏感的检测到。

The welding nugget happened to dynamically recrystallize and the refined crystal grains were obtained and the majority of Mg_2Si particles dissoluted due to the intensive mechanical stir and higher high temperature. In the thermal-mechanical affect zone that was heated under the recrystallized temperature, the crystal grains were elongated due to the mechanical stir and Mg_2Si particles partly dissoluted and the others grew. In the heat affect heat without the mechanical stir, to some extent, both of the crystal grains and the majority of Mg_2Si particles grew.

分别采用50℃下搁置4天和常温下搁置28天两种不同方法检测了MH-Ni电池荷电保持能力，并对试验数据进行了方差分析，结果表明短期高温搁置法可以达到与常温搁置法同等的效果。

Combined crystallization kinetics analysis obtained via rheometry and morphological observation of crystals growth performed on POM, two different mechanisms of shear-enhanced crystallization for PP/ grafted MWCNTs composites were suggested:(1) at low temperature, strong heterogeneous nucleation plays a dominant role on the. crystallization behavior, which would be saturated at a higher filler content, and the effect of shear-enhanced crystallization was weak;(2) at high temperature, the effect of heterogeneous nucleation was substantially depressed, and the crystallization of the composite was obviously accelerated by pre-shear and the thread-like crystallites were generated earlier than the spherulites.

结合流变测试结果和热台偏光显微镜观察的结晶形貌发展过程，对于PP／G—MWCNTs体系得到了两个不同的剪切影响机理：(1)在低温条件下，强烈的异相成核作用对结晶行为的影响占主导优势，而剪切作用对结晶的影响十分微弱，同时，在填料含量较高是，异相成核作用具有饱和性；(2)在高温条件下，异相成核作用被抑制，复合体系的结晶主要受到预剪切作用的影响，并且纤维状晶体较球晶更易生成。
