This paper using the FEM software Marc, for the 50 and 60 degree V groove of flat plate butt joint simulate the one-layer and three layers welding, finish each welding and cooling it down to room-temperature then start the next welding true represent process and get the temperature field, residual deformation and welding residual stress, according to the theory analysis and empirical equation verified the temperature field and residual deformation all correct, comparison with experiment verified the welding residual stress regularity and correctly.

本文利用有限元软件Marc，对开60°和50°V型坡口的平板对接接头，动态的模拟了单层单道打底焊，焊完一道后让试件冷却到室温以及单层单道满焊，每焊完一道后让试件冷却，然后再焊下一焊道，道间温度≤200℃，在以此为初始边界条件下开始下一道的焊接，真实的再现了焊接过程，得出了温度场，残余变形和残余应力场的分布规律，根据理论分析及经验公式验证了温度场以及残余变形的正确性，角变形的大小，这些结果与数值计算相吻合。通过与实验测得的残余应力进行比较，验证了焊接残余应力的分布规律及模拟的正确性。

It is pointed out that due to the difference of the temperature expand coefficient of aluminum alloy gear case and steel bolt, when the temperature of the gear case increased,additional temperature-difference load is generated,which is the ultimate reason of the bolt failure.

指出由于铝合金齿轮箱和钢制螺栓的热膨胀系数不同，在齿轮箱温度升高后产生附加的温差载荷，此温差载荷是螺栓失效的根本原因，由此依据相关公式提出了改进措施。

According to heat load source of die cavity, temperature distribution gradient equations and heat flux equations and the peak value equations of temperature load at die cavity surface have been obtained with research of temperature distribution and transfer laws of die surface by unsteady heat transfer theory.

For example, in cases where the target temperature is 60° C., the fan revolution speed, which is shown by a two-dot chain line, does not rise immediately when the actual temperature of the cooling target fluid exceeds the target temperature of 60° C.

例如，在的情况下，目标温度为60 ° C时，风扇转速，这是表现出两个斑点链路线，并没有立即上升时，实际温度的冷却液指标超过目标温度为60 ℃之间，但后，冷却液的目标，极大地overshoots目标温度。

Measures of improving for low temperature toughness by selecting the welding materials and strictly controlling the welding process for welded joints of low temperature low-alloy steel, nickel alloy steel and chrome-nickel austenitic stainless steel for low temperature pressure vessels were summed up.

为了改善工作于低温环境的压力容器用低合金低温钢、镍合金钢和铬镍奥氏体不锈钢的焊接接头低温韧性，而采取改进焊接材料、严格控制焊接工艺的措施。

The cooling crystallization and the polymorphic transition processes of L-Serine in aqueous solution were real time monitored by PVM and FBRM. The results show that at a higher temperature, the anhydrous crystals form in club-shaped habit, while the temperature of the slurry was cooled under the polymorphic transition temperature, the club-shaped anhydrous crystals would translate to the hexagonal plate-shaped monohydrate crystals.

利用PVM和FBRM对L-丝氨酸水溶液的冷却结晶过程和晶型转变现象进行的实时监测表明，在高温区析出的是棒状无水合L-丝氨酸晶体，当冷却至晶型转变温度以下时，棒状晶体逐渐转变为六角片状的水合晶体。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.
