"This is my time," she said, and Destiny saw the shadow that spread onto his page raise its arms, as if embracing the gloaming sky.

The fluorescence intensity grew and emission wavelength gradually increased between 331nm and 350nm under the condition of strong acid(pH=3.5), strong alkaline(pH=12.1)and high temperature(80 °C), showing that the conformation of lipase protein changed from globularity to unfolding state.

发现游离酶蛋白质在高温(80℃)，强酸(pH=3.5)、强碱(pH=12.1)，变性剂的作用下基本表现为荧光强度增大，最大发射波长在331～350nm之内逐渐增大，说明蛋白质整体构象从球状到了伸展状态。

Himalaya, which formed on the basement of the Pan-African orogenic event at about 550 Ma BP and experienced Ordovician to Devonian platform sedimentation, was transformed into to a back-arc extensional-rifted zone at the end of the Carboniferous. The Yarlung Zangbo ophiolitic mélange zone is a Mesozoic back-arc spreading basin corresponding to the Gangdise paleo-island arc zone on the south side of the Tethyan Ocean. The Gangdise zone experienced island-arc orogeny in the Late Paleozoic. The very significant differences in geology on both sides of the Bangong Co-Nujiang suture zone suggest that the suture zone is not only the northern boundary of Gondwanaland and the boundary between the Indian (Yunnan-Tibet) stratigraphic realm and the South China (Qiangtang-Sanjiang) stratigraphic realm, but also the relics of subductional collision and final extinction of the Phanerozoic Tethyan Ocean after the breakup of the Neoproterozoic supercontinent Rodinia. The basic point of study of the collisional orogenic processes of the plateau is the structure and composition of the archipelagic arc-basin tectonic realm of three different stages bounded by three rigid paleocontinental blocks (Gondwanaland, Laurasia and Pan-Cathaysian) and the mutual constraining, transformation and coupling of various material movement forms.

喜马拉雅奠基于5.5亿年左右的泛非造山事件基底上，历经奥陶纪至泥盆纪台地沉积，并于石炭纪末转化为印度板块北缘的弧后伸展裂陷带；雅鲁藏布江蛇绿混杂岩带曾是特提斯大洋南侧与冈底斯古岛弧带相对应的中生代弧后扩张盆地；冈底斯带曾经历了晚古生代岛弧造山作用；班公湖-怒江带两侧大量地质特征重大差异表明，班公湖-怒江带是冈瓦纳大陆北界，是印度地层区和华南地层区的分界，是新元古代Rodinia超大陆解体后显生宙特提斯大洋俯冲，消减，碰撞，最后消亡的遗迹。

Richard Gowan, of New York University, notes that sub-Saharan countries have many wars but hardly any helicopters; traditional UN troop contributors, such as India, are close to the limit of what they can supply; some Western countries such as America and Britain are overstretched in Iraq and Afghanistan; while others are reluctant to become involved in fighting, be it counter-insurgency or tough peacekeeping.

纽约大学的理查德·高万指出，撒哈拉以南地区发生了许多战争，但几乎没有直升机；联合国维和部队的传统派出国，如印度，已接近其所能供应的极限；而美英等一些西方国家则在伊拉克和阿富汗过度伸展；其它国家则不愿卷入战斗，无论是反叛乱还是困难重重的维和行动。

Yitong graben is a strike-slip and extensional basin in Meso-Cenozoic, the eastern China.

Based on the characteristics of the basins, there are three types of basins in the area: graben, listric faults and transform-extension.

根据区内盆地特征，可划分为地堑型盆地、铲状断层型盆地和变换－伸展型盆地3类。

The vein type mineralization of the Maanqiao was formed from the mixture of magmatic gases with basin oil hot brine and the boiling of ore-forming fluids, the mixture of aside magmatic gas with basin oil hot brine brought on the reformed vein type ores of the Huoshibulake during the irruption of granite porphyry veins.

改造成矿作用主要发生在造山作用后伸展期的岩浆活动阶段，岩浆气液和盆地油田热卤水的混合形成改造热液，形成了马鞍桥和霍什布拉克矿床的脉状矿化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
