    論述了三峽大江截流及二期圍堰實施過程中的施工進度計劃、料場規劃與土石方平衡、截流方式與圍堰斷面形式、截流進占程序和時段、防滲形式、防滲墻施工等主要技術問題的優化完善過程
  2. With the increase of substrate salinity, the accumulated sodium and chloride increased. as a result, all tissues had considerablly lower osmotic potentials than that of the solution on which they were grown at 60 day after planting. changes in length, dry weight, water content, ion concentrations, osomotic potential, ion content of hypocotyls during culture indicated that viviparous hypocotyls not only afforded nutrition for seedling growth, but also reserved ions, thus charged the balance of ion concentration and osmotic potential of the seedling

    鹽脅迫下幼苗單株葉面積下降的程度大於光合速率的降低，葉面積的減小是導致減產的主要原因；木欖幼苗各組分中的離子濃度以及含量隨栽培時間而變化；栽培初期剛萌根時，幼苗原胚軸中的離子滲漏到培養液中；此後隨著根系的發育以及芽的生長，幼苗轉為從培養液中吸收離子，並以吸收na 、 cl離子為主。
