Results: Standardization regression coefficient from big to small in proper order were: oxygenation index, CT, body temperature of the admission day, BMI were the most influence on ALI; 结果:按标准化回归系数绝对值由大到小:氧合指数、CT、入院体温、体质量指数对ALI的影响最大;
The resistance to material flow is influenced by the cross-sectional shape of gravity lines and coefficient of admission of materials, so the oblique angle of line is different. 溜管的截面形状、物料的充满系数不同,物料所受的流动阻力也不同,所需要的溜管倾角也不同。
