The result shows that : the sand - dust storm occured in favorable climate background that is drought and rainless, the tilted trough and mongolia cyclone are the important weather systems that caused the severe sand - dust storm, tilted trough and strong frontal zone caused the mongolia cyclone developed and the clod front strengthened at surface, high jet and ferrel circulation are the main reason that momentum spreaded downward from higher level and frontal zone strengthened on lower level
結果表明：沙塵暴是在乾旱少雨的有利的氣候背景下產生的。斜壓槽和蒙古氣旋是觸發這次強沙塵暴天氣過程的重要的天氣系統，高空斜壓槽和強鋒區促使了地面蒙古氣旋的發展和冷鋒的加強，誘發沙塵暴天氣。高空急流及其下方的ferrel環流起到了高層動量下傳和加強低層鋒區的重要作用。 -
The expressions of displacement fields of dorsal and frontal surface for two piles, row piles and group piles are derived. the solution taking into consideration the effect of construction sequence of jacked pile accords with the actual engineering
該式考慮到了沉樁施工順序的影響，較各樁的簡單疊加更符合工程實際情況，而且能夠簡化為不考慮施工順序的靜壓群樁擠土位移場的解答。 -
2. on the basis of analyzing experimental data for slope land of loess plateau in different slope gradient and rain intensity and soil and water conservation tillage measures, using curve - fitting techniques, a soil infiltration rates model was woke out, the accuracy of the model is tested by a series of experiment data, the result of these indicate that the soil infiltration rates model is accurate and has good stability for slope land of loess plateau. 3. using soil infiltration rates and runoff time and wetting frontal surface depth of soil infiltration reflect effect of factor affecting soil infiltration rates
（ 3 ）採用土壤穩定入滲速率、坡面開始產流時間、土壤濕潤鋒面下滲深度三個指標來反映坡耕地土壤入滲影響（土壤性質、土壤初始含水率、地面坡度、降雨強度、積水深度、水土保持耕作措施等）因素效用大小，建立了各因素與三個指標的關系模型，詳細分析了不同水土保持耕作措施強化土壤入滲的影響，其中等高耕作作用最為顯著，其次是人工掏挖和人工鋤耕。 -
