mechanical原来还有这个意思!? mechanical 英音:[mi'kænikəl] 美音:[mə'kænɪk!] 形容词 a. 1.机械的,用机械的[Z] They were using a mechanical shovel to clear up the streets. 他们用机械铲土机清理街道。 2.似机械的,呆板的,无表情的,无意识的 Blinking is a mechanical action of the eyelids. 眨眼是眼睑的无意识动作。 3.机械学的,力学的;物理的 4.手工操作的,技工的 5.技巧上的,细节上的 以上结果由"Dr.eye译典通字典"提供 小妹查了字典,看到第5个义项和上文的翻译比较相关。文章正如Echo前辈所说,的确与过滤有关。 In general, the pores of the medium will be larger than the particles which are to be removed, and the filter will work efficiently only after an initial deposit has been trapped in the medium. in the chemical laboratory, filtration is often carried out in a form of Buchner funnel, and the liquid is sucked through the thin layer of particles using source of vacuum. In the industrial equivalent of such an operation, difficulties are involved in the mechanical handling of much larger quantities of suspension and solids. A thicker layer of solids has to form and, in order to achieve a high rate of passage of liquid through the solid, higher pressures will be needed, and it will be necessary to provide a far greater area. 查看更多10个回答 . 3人已关注
