查询词典 RH

Steelmaking Plant can be reduced to 20ppm by increasing argon flow of RH degasser and controlling vacuity According to the above results, the main efforts to develop IF steels have been made at No 3 Steelmaking Plant.

研究结果表明：钢水增碳主要在大包中发生，影响钢水增碳的主要因素是钢液与包壁接触面积与钢水体积之比，在高温下，耐火材料中CO的压力和钢水中Als的含量对钢水增碳也有一定的影响；钢水脱氧后将增硅，钢水的增硅量主要受大包渣的碱度、中包绝热板材料和中包保护渣碱度的影响；通过增大RH真空处理装置的氩气流量和控制真空度，能将三炼钢厂大包钢水的碳含量降到20ppm左右。

A modified homogeneous flow model was introduced to calculate the flow field in RH degasser,thus getting rid of some earlier methods that are unavailable to be generalized,such as reducing the computation region or presetting the distribution of gas volume fraction.

分别对有、无旋转磁场作用时的RH系统进行了模拟计算。模拟结果表明：流场和脱碳过程与现有文献中实验结果相符合；当旋转磁场作用后，磁感应强度为0.04 T时，初期脱碳速度比无旋流作用时增加了约15%，这是由于旋流增加了系统的搅拌能，提高了脱碳反应速率。

Moreover, taking the adsorption process from oven-dry state to the equilibrium state in 20℃,60%RH environment as an example, the dielectric relaxation based on the reorientation of adsorbed water molecules was separated out from that based on the methylol groups in the amorphous region of wood cell wall.

以绝干状态→20℃，60%RH 平衡态的吸湿过程为例，将基于吸着水分子回转取向运动的介电弛豫与基于木材无定形区中伯醇羟基回转取向运动的介电弛豫进行分离，并在 Eyring 的绝对速度反应论的基础上，求得了与吸着水分子进行回转取向运动相关连的热力学量，得到了在吸着过程中吸着水分子与木材吸着点之间的氢键结合随着水分吸着进程的变化情况。
