Therefore developing the analysis and research about flow field and temperature field of molten steel in the slab crystallizer is very important.

本文以国内某钢铁公司的板坯连铸机结晶器为研究对象，重点分析了拉坯速度、水口倾角和水口浸入深度对流场和温度场的影响，以及过热度对温度场的影响。

The crystallographic textures in the first group are characterized by the relatively weak {111} and {114} components;for the second group, the characteristic texture co...

结果表明，带铸材试样中存在{111}与{114}特征织构，织构强度均较弱；铸坯切片中存在{111}与{001}特征织构，并且因局部凝固冷速不同存在明显的织构强度差异。

In the simulation, the flow rule of melt metal in mold of horizontal continuous casting with electromagnetic stirring is measured using ultrasonic Doppler velometer, and the result is inter confirmed with the solidification characteristics is tics of zinc cupronickel thin slab in industrial product, some advantageous results are obtained that, when the current is 400 A the inner micro-pores disappear, when the current is 500 A the center equiaxed crystal layers occur and when the current is to 800 A the inner-segregation decreases to zero.

在模拟实验中，用超声波多普勒测速仪测量该电磁搅拌下水平连铸结晶器内金属液的流动规律，并与生产实验中锌白铜板带的凝固特征相互印证，发现搅拌电流达到400 A时，板带内部气孔消失，电流达到500 A时板带出现等轴晶带，电流达到800 A时板带坯偏析率趋于零。

The white porcelain has a beautiful clour and special shape which could be regarded as the curiosa in tea sets.

瓷器茶具常见的是白瓷盖碗，白瓷盖碗具有坯质致密，上釉、成陶火度高，无吸水性；传热、保温性能适中；加之色彩缤纷，造型各异，堪称饮茶器皿中之珍品。

The analysis show that O-forming is accomplished by bending of subdividing suspend arc,characterized by evolvement of curvature peaks form one to multiple peaks,which have nearly equal peak-to-peak distance.

UOE是以热轧厚钢板为原料，通过预弯边、U成形、O成形和对埋弧焊接管坯扩径等成形工序制造大口径直缝焊管的一种工艺。

In another room, women are dabbing designs on to biscuit-fired pieces with sponges.

在另一个房间，女工们正用海绵将图案轻轻拍到陶器素坯上。

Ain't trash; and I'm damned if I'll have any man, darky or white

他虽然穷，可并不是什么下流坯。

The condition of numerical simulation on extrusion deformation is that the extrusion ratio is 4100, preheating temperature of billet is 300450 ℃ and extrusion ram speed is 220 mm/s.

模拟采用的挤压变形条件为：挤压比4~100，锭坯预热温度300~450 ℃，挤压杆速度2~20 mm/s。

In addition, mechanisms involving densification and formation of pyrocarbon were discussed.

此外，还对坯体的致密化机理和热解炭的形成机理进行了初步的探讨。

In the culture phase, a great deal of protease, lipase,α_amylase and diastase were accumulated on the skin of beancurd. After 36 h, the thallus began to decay and the activity of all these enzymes began to decline.

培菌阶段在豆腐坯表面积累了大量的蛋白酶、脂肪酶、α_淀粉酶及糖化酶，培菌36 h后菌体开始老化，酶活有所下降。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
