velocity n. 1.迅速;快速。 2.速度,速率。 3.周转率。 at a velocity of 100 miles per hour 用每小时一百英里的速度。 dart off with the velocity of a bird 像鸟一样迅速飞跑过去。 drag-free velocity无阻力飞速,真空飞速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (发射物的)终速。 initial [muzzle] velocity(发射物的)初速[腔口速度]。 uniform [variable] velocity匀[变]速。
The experimental results indicate that electroosmosis technology can further the filtering velocity markedly , increase the compressive strength of concrete significantly and have finer economical efficiency 结果实验表明电渗技术可以显著提高滤水混凝土的滤水速度,明显提高混凝土的强度,并有很好的经济性。
This article makes a model test research to filter function of porcelain sand filter according to the new material - porcelain sand filter - that baogang uses in the new water processing technology of sheet semifinished turbidity of the inlet water , different medicine and variation of outlet water quality in different filter velocity 本文针对包钢薄板坯连铸连轧新水处理工艺中所采用的新型滤料? ?瓷砂均质滤料的过滤特性进行了研究。在不同的进水浊度、不同的加药量、不同的滤速下出水水质的变化,对瓷砂滤料过滤性能进行了模型试验研究。
