The process and matters needing attention of aqua pura production by inverse penetration proces were introduced. 介绍了反渗透技术制取纯水的工艺及运行中的注意事项。
Operating cycle of ion exchange unit was prolonged with less discharge of sewage, due to 98% desalting rate of inverse penetration unit. 反渗透系统除盐率达98%左右,从而延长了离子交换器运行周期,减少了污水排放量。
Study on the Inverse Bremsstrahlung Absorption of the Plasma in the Keyhole in Deep Penetration Laser Welding 激光深熔焊接小孔内等离子体的反韧致辐射吸收研究
The demineralized water is prepared from the inverse penetration freshwater by using ion-exchange resin. The utilization of high purity fresh alkali instead of industrial lye can save the regeneration cost by 80%, and what is more, it greatly decreases the regeneration cycle. 以反渗透淡水为水源,采用离子交换法制备脱盐水,用高纯度片碱取代原工业液碱作再生剂,实现再生费用节约80%,再生频率也大幅下降。
On the assumption of conical keyhole and using geometrical optics theory, a detailed study of the inverse Bremsstrahlung absorption of the plasma in the keyhole in deep penetration laser welding of metals was carried out by tracing a beam ray. 在假设小孔为圆锥形的基础上,按照几何光学理论,通过跟踪光线在小孔内的多次反射轨迹,对激光深熔焊接小孔内等离子体的反韧致辐射吸收进行了详细研究。
The technology provides an alternative approach to quickly determine parameters of constitutive model under high strain rate. ( 2) An inverse technology based on the structure-selection technique is proposed to identify penetration force. 这种方法为快速获得高应变率下本构参数提供了一种解决途径。(2)构建了一种基于结构选择技术的侵彻载荷参量反求技术。
