A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass. The size distribution is often of critical importance to the way the material performs in use. A sie… Web扭矩适应性系数 coefficient of torque adaptibility 转速适应性系数 speed adaptive coefficient. 强化系数 coefficient of intensification. ... 滤网 sieve. 滤纸盘或膜 filter paper disc or membrane. 进气和排气系统 intake and exhaust system. 排气管 exhaust pipe.
