Abstract : the main characters and seed set of bc1 ， bc2 ， bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields

是指保育生態系和自然生境以及維持和恢復物種在其自然環境中有生存力的族群；對于馴化和栽培物種而言，是指它們在其中發展出其明顯特性的環境之保育。Took sha - zhuyu and east shore of qing - hai lake as the examples and based on the mass of field survey and soil analyse, took comparative method, we carried through the researches on the causes of the desertification, the origin of sandy desertificational land substance, the development diversification and difference of soil characteristic in process of manual and spontaneous vegetation recovery in high frigid regions and make out the taxonomy of desertificational land in high frigid region of china. the result obtained are summarized as follows : 1. the development of the desertificational land in high frigid regions is caused by the manual and spontaneous factors
論文首次對高寒地區的砂質荒漠化土壤進行系統研究，以沙珠玉和青海湖東岸為例，通過野外考察和土壤樣品室內化驗，採用對比分析的研究方法，對中國高寒地區荒漠化的成因和研究區砂質荒漠化土地的形成演變，土壤發生特性、人工植被恢復和自然植被恢復過程中土壤的發育差異和性質變化進行系統研究，並用系統分類體系對研究區土壤進行類型劃分，得到主要結論如下： 1 、高寒地區荒漠化的發生發展是在自然因素和人為因素共同作用下進行的，沙珠玉地區風沙土是就地產生的，青海湖東岸地區風沙土主要是由風從湖的西岸搬運而來的，兩地區砂質荒漠化發展仍然十分嚴重。These restorer lines showed both stable and uniform agronomical characters and a good restoring ability, and their testcrossing f1 hybrids had a strong heterosis in grain yield, which indicates that the recurrent selection provides an effective way in breeding of three - line japonica restorer lines and makes it possible the commercial production of three - line japonica hybrid rice in north cold rice growing area in china

高粱雄性不育系與恢復系在育種和生產中的應用By comparing the numerical results of water infiltration with air and without air, it is shown that the method in this paper is more effective for solving problems of water infiltration in unsaturated soil. in this paper the forming process of oil - bearing basin is the main research object and the mathematic model of geology is built, in order to simulate the dynamic forming process of stratums especially oil - bearing stratum in geology history in the time and space concept, further to investigate the history of petroleum forming, transmitting, accumulating and predict the distributing rule and scope of petroleum, and offer an rapid, quantitative, exact, general choice for the researcher of petroleum geology. with denudation, poor - compactness and sedimentation hiatus, the stratum relations of sedimentation section is judged, and the ancient thickness and pressure of stratum layer are recovered by the inversion method of back stripping. the numerical simulation algorithm of recovery of geological history is also given
為了利用現代化的計算技術再現含油氣盆地的地史演化發育過程，以便進一步定量化研究油氣的生成、運移和聚集的歷史以及預測油氣分佈規律、分佈范圍，為石油地質學家提供一個快速、準確、定量、綜合的研究手段，本文就含油氣盆地的地史演化發育過程為主要研究對象，建立了數學地質模型，運用優化理論與演算法，在考慮了剝蝕、欠壓實、沉積間斷等地質現象的情況下，採用回剝反演法，應用鉆井、測井、地震等方法獲得的地層物性資料，判別沉積剖面中地層的接觸關系，恢復地層的古厚度、古壓力，構造了地史恢復的數值模擬方法。Based on the study of the test pressure data, the acoustic time and the reconstrction of paleoformation pressure, through the study of abnormal pressure in the middle and western sichuan basin, it ' s shown that the distribution of stratum pressure differs greatly in different zones ; the evolution history of paleo - formation pressure has been restored according to the models of the evolution history of pressure, and it shows that there were two high pressure arouse, the first arouse in later jurassic and the second in erlier triassic, analyzing the relations between the excessive pressure distribution and the petroleum migration
