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。

这一相变发生在电子半填满的区域，是一个一级相变。

The results of simulations performed at nearly zero temperature demonstrate that stress-induced phase transitions from body-centered cubic to face-centered cubic and hexagonal close-packed structures take place during the deformation process of both Fe and Ta, and the maximum fraction of FCC atoms varies linearly with the tensile strength, from which we can conclude that a critical stress exists for the phase transition to take place.

低温模拟结果表明，纳米晶铁和钽在变形过程中都出现了应力诱导的相变，其中FCC结构含量的最大值和抗拉强度成线性关系，并由此可以推出相变发生的临界应力值。

本文还讨论了相变中的熵和比热对温度的依赖关系，发现熵在相变过程中是随温度连续变化的，而比热则是不连续的。

It was found that the baryon asymmetry might be produced in the electroweak transition process at hot dilut conditions, but not at cold dense conditions.

我们发现：重子数不守恒可能产生于高温低密下的弱电相变过程，但不能产生于低温高密环境下的弱电相变过程。

The study and comprehensive analysis of static high-pressure quenching experiments and laboratory dynamic high-pressure experiments on chondrites,as well as the study of shock-induced phase transition of minerals in the Suizhou meteorite revealed that the P-T conditions for phase transition of minerals during natural impact events,such as collision of cosmic bodies or impact of meteorites on the Earth′s surface,are not consistent with those obtained by shock experiments on chondrites or rocks in laboratory,...

通过对球粒陨石的静态高压淬火实验和人工动态高压实验的研究和综合分析，以及对在太空中经受过撞击的随州陨石中矿物发生高压相变的研究，查明了自然界的冲击事件，如星体的相互碰撞和陨石对地球表面的撞击中，矿物发生相变的P-T条件与人工冲击波实验的结果并不一致，而与静态高压淬火实验的结果相似，即前者类似静态高压淬火实验，保压时间较长，能产生高压矿物，后者保压时间极短，无高压矿物形成。

The fermion environment is considered from zero temperature to the critical temperature. It is show that the decoherence of the two-level system may also act as the witness of the environments phase transitions, which is similar to the relation between quantum phase transitions and decoherence in the former study.

对于一维XY自旋链系统，二粒子系统的纠缠度会在自旋链的量子相变临界点附近发生剧烈的变化，这种剧烈的变化正是量子相变的一种外在体现。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
