By use of the double-jetapparatus controlled by a microcomputer, cubo-octahedral AgBr grain emulsions in which formate ions were doped at subsurface of AgBr microcrystals, were prepared.
使用反馈式微机控制双注乳化仪，制备了甲酸根离子掺杂于颗粒次表面的立方八面体溴化银微晶乳剂。

As one of radial horizontal drilling techniques, high pressure water jet drilling technology is capable of using mechanical or water jetapparatus to make a cavity at the selected coal seam.
Special testing apparatus was built to study the effect of arc divided flow on the jet fluctuation and the inhibiting effect of new spray gun on the jet fluctuation.
