水泥孔隙比 例句

1. The black earth is a kind of alfisol, with a thick layer of humus, loose texture, high fertility, high porosity ratio, poor permeability and a high content of clay, which is suitable for cultivation
   摘要黑土是一種腐殖質層厚，質地鬆散，肥力很高， 孔 隙 比 較大而透 水 性差，粘粒含量高，適于耕作的淋溶土。
2. With the development of human society, because of the lack of sustainable utilization consciousness, and the eager for quick success and instant benefit, the black earth suffered excessive cultivation and management, causing the reduction of its recycled ability, decrease in organic content, porosity ratio, fertility dropped and the properties of water retaining and water retention, which make the black soil harden and degenerate seriously
   但是隨著人類社會的發展，在缺乏保護和可持續利用意識、急功近利思想影響下，黑土遭到過度墾殖和掠奪式經營，人類對其活動范圍遠遠超過了其再生能力，導致有機質含量減少，肥力下降， 孔 隙 比 減小，保 水 持 水 能力降低，土壤板結，黑土嚴重退化。
