Baishishan the top of the dolomite cap rock was formed 10 billion years ago the marine environment; crustal movement to make this piece of dolomitic marble produced more than two sets of vertical joints, in the long years of millions of years later, the weathering so that the vertical cracks expanding into a arrhizus rock column of Qifeng Li; Moreover, these columns, such as Lin Qifeng Li has just standing on a solid granite base, making them also another insurance Fenglin odd geological movement continues to be able to has been retained.

白石山上部的白云岩盖层形成于10亿年前的海洋环境；地壳运动使这块白云质大理岩产生了两组以上的垂直节理，在后来亿万年漫长的岁月里，风化作用使垂直裂隙不断扩大，岩层变成了根根柱立的奇峰；而且，这些柱立如林的奇峰又正好伫立在稳固的花岗岩基座上，使得这些又奇又险的峰林在不断的地质运动中能够被保留下来。

The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。

It is found that TiO2/pillared MMT (TiO2/MMT) composite catalyst exhibits the best degradation activity to methylene blue and methyl orange compared with other semicondutors/MMT, such as SnO2/MMT, Fe2O3/MMT and Cu2O/MMT with different energy gaps that is closely correlated with the formation of stable pillar stucture and appropriate energy gap in the TiO2/MMT.

Then they surrendered to the Ghaznavids. In the process of participating the tussles, the Seljuq people were gradually becoming stronger. Nearly one hundred years later, they developed from a barbaric uncivilized tribe who only took up a tiny area, to a great force that could sway the situation of the Central Asia. Finally, they defeated the regular army of the Ghaznavids and seized Khurasan in the north of the Amu Darya.
