The original alkalic series of basalic magma evolutes into trachybasalt through crystallization differentiation of olivine and pyroxene, and the trachybasalt is transformed into alkalic rhyolite with remarkable Eu, Sr, Ba, Ti, P nagetive abnormalities through strong crystallization differentiation of plagioclase and also pyroxene Ti Fe oxides and apatite, all together leading to the loss of neutral (SiO 2=57%～63%) andesite and trachyandesite in the volcanic rocks in this area and appearance of bimodal volcanic rock combination feature.

原始碱性系列玄武质岩浆经橄榄石、辉石的结晶分异，向粗面玄武岩演化；粗面玄武岩经斜长石强烈的结晶分离作用，还有辉石、钛铁氧化物和磷灰石的分离结晶作用形成具显著Eu、Sr、Ba、Ti、P负异常的碱性流纹岩，导致本区火山岩缺失中性(SiO2=57%～63%)的安山岩和粗安岩，呈现双峰式火山岩组合的特点。

As compared with undrawn PET film, the hot drawn PET film showed shorter crystallization induction period, faster development of long period, anisotropic in SAXS and WAXD patterns, with considerable thermal contraction along the direction of drawing and small lengthening in the direction of drawing during crystallization.

研究结果表明：热拉PET膜的结晶诱导期较短，长周期发展得较快，结晶后小角X-线散射表现出明显的各向异性，在热处理过程中先出现显著的热收缩，随后又表现出结晶伸长现象，这些都和未拉试样有明显的差别。

DSC results show that crystallinity of the geogrids ribs is different owing to various stretching technical factors, and that the crystallinity of the stretched sample is larger than the unstretched one. The crystallinities of the sample are similar at lower draw temperature and higher draw speed, which show that there is correlation among the stretching factors.

通过对试样肋条部位结构的DSC分析，发现拉伸工艺参数不同，肋条部位的结晶度不同，且拉伸后试样的结晶度均比未拉伸时有所提高；较低拉伸温度下与较高拉伸速率下试样的结晶度相近，表明各拉伸参数之间具有一定的关联性。
