Then we studied the double phase transition behavior of three-layer nanostructures with double thermoresponsive shells. Successive RAFT polymerization of NIPAM and 2-ethyl methacrylate or DMA and NIPAM were conducted using PS macroRAFT agent. The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas.

另外我们还合成了含有PS、PNIPAM、PDMA三嵌段聚合物，也利用芘标记的方法可以得出：对于PS-b-PNIPAM-(来源：A29BC论文网www.abclunwen.com)b-PDMA胶束存在两个明显的相转变过程，第一个是内层的PNIPAM这一个很宽的温度(20-32℃)的塌缩过程，接着是32-50℃下的PNIPAM和PDMA的混合塌缩或聚集过程。

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.

盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

The experiment studies revealed Atom Force Microscope observed vital human erythrocytes that incubated at different temperatures in plasma physiological environment, that surface microstructure of the cell membranes were shapely sensitive to the altered temperature increasingly, and that liquid crystalline state bio-membrane were slightly perturbed and happened phase transition. In the optical tweezers experiment, the captive erythrocytes were encaged in the three-dimensional laser optical potential well, and able to well maintain physiology characteristic property and intact shapes.

实验研究显示，在血浆生理环境中不同温度孵育的红细胞经原子力显微镜观测，其膜表面微观结构对温度变化比较灵敏，液晶态生物膜被扰动而发生轻微相变；在光镊捕获实验中，三维激光势阱囚禁的红细胞却仍能够维持良好生理特性和完好形态，并且细胞膜表面存在相互作用力。

近年来，人们在研究过渡金属气相反应中发现基态反应物和基态产物有着不同的自旋态，即不遵守&自旋守恒定律&。

He's also recommended that in December we begin a transition to the next phase of our strategy in Iraq, in which our troops will shift over time from leading operations to partnering with Iraqi forces, and eventually to overwatching those forces.

他也建议，在12月，我们开始转入到我们在伊拉克的下一步战略阶段，就是我们的军队将逐渐从领导行动的角色转换为辅助伊拉克军队行动的角色，从而最终达到掩护他们的军队。

He's also recommended that in December we begin a transition to the next phase of our strategy in Iraq, in which our troops will shift over time from leading operations to partnering with Iraqi forces, and eventually to overwatching those forces.

他同时建议我们从12月开始转入到我们对伊战略的第二部，我们的部队将从直接主导作战转换到协同伊军，进而最终变成掩护伊军的角色。

A process for continuously preparing nm carbon tubes on fluidized bed include such steps as carrying the transition metal oxide catalyst on carrier, putting it in catalyst-activating reactor, reduction reaction by introducing the gas mixture of nitrogen gas and hydrogen or CO gas to the reactor, loading the catalyst into fluidized bed, and introducing mixed reaction gas to its to grow said nm carbon tubes on the catalyst by chemical gas-phase deposition.

本发明涉及一种流化床连续化制备碳纳米管的方法，首先将过渡金属的氧化物催化剂载于担体上，然后将其放在催化剂活化反应器内，通入流动的氢气或一氧化碳与氮气的混合气体进行还原反应，最后将催化剂送至流化床中，通入反应混合气体，流化床的下部则得到碳纳米管。本发明的方法和装置，在流化床中经过化学气相沉积，在催化剂载体上生长出碳纳米管。
