  1. Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins

    2沉積物地球化學與化學風化進程和率化學風化指數與化學風化率屬于表徵化學風化意義不同的函數,前者為相對概念反映流域巖石在原巖基礎上己發生淋溶的深度,主要受到了氣候因子的深刻影響(中國流域沉積物化學風化指數由北到南呈有規則的遞增序列,氣候因子對風化進程的影響掩蓋了巖性的巨大差異) ,而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。
  2. Fluid machinery in these areas is damaged due to cavitation and sand abrasion, which has threaten directly the safety operation of hydraulic and hydroelectric engineering, causing huge economic losses. the research, therefore, on the combined effect of cavitation and sand abrasion is of great significance. the researchers at home and abroad have done a lot of work on this issue

    我國許多河流的含沙量較大,如著名的黃河幹流年均含沙量達37 . 9m ~ 3 / s ,黃河三門峽的年平均輸沙量達16億t ,這些地區使的泵、水輪等許多流體都在夾沙水流的下,受到了沙粒磨損與空化的聯合破壞,這種破壞直接危害了水利水電工程的安全運行,造成了巨大的經濟損失,因而對含沙水流條件下空化與泥沙磨損聯合進行研究有著很大的工程實際意義。
