When we try to determine our own relationship with the dhamma, eventually we find ourselves challenged to make sense out of its two seemingly irreconcilable faces : the empiricist face turned to the world, telling us to investigate and verify things for ourselves, and the religious face turned to the beyond, advising us to dispel our doubts and place trust in the teacher and his teaching
我們在嘗試決定自身與佛法的關系時，最終都會發現受到挑戰，需要對這兩副看上去不可調和的面貌作出合理的解釋:經驗主義的那一面朝向世界，告誡我們對萬事親自作調查與驗證，宗教性的那一面朝向超世，告誡我們遣除疑念，信賴尊師佛陀與他的教導。Twenty f1 combinations crossed among 5 varieties and strains different in fiber properties according to complete diallel crossing design were used to evaluate the heterosis and gene action of boll weight and lint percentage in high quality fiber property varieties in upland cotton in 1998 1999 for two year successively at nanjing. it was indicated that there existed small interactions with the environmental factors without maternal effects and the additive gene effect was in chief, attaining to 51. 2 % and 65. 4 % respectively for boll weight and lint percentage. the dominant effect was also in higher rate, 32. 6 % and 16. 8 % respectively. the population mean heterosis of boll weight and lint percentage over the mid - parental mean were relatively prominent 13. 3 % and 3. 5 % respectively in extreme significance. however, boll weight showed no significantly surpassing parental f1 heterosis over the better parent based on population mean ( 2. 0 % ) ; while the lint percentage expressed significant negative heterosis value ( - 2. 1 % ). the gene actions were in conformity with the heterosis expression. it was shown clearly that the f1 combinations crossed between parents with similar performances had relatively high dominant effects and significant positive f1 surpassing parental heterosis ( f1 heterosis over the better parent ) ; while no f1 combination crossed between the parents with prominent mutual difference surpassed the higher parent in yield components, which indicated that among those parents with less difference and close relationships, there still existed sufficient genetic variation or certain mechanism for creating variation and achieving greater advances in breeding. correlation analyses also indicated that there still existed severely undesirable negative correlation between yield and fiber properties as well as the difficulties for their simultaneous improvements
利用5個具有不同纖維品質性狀的品種（系）配製完全雙列雜交組合20個，通過親本和f1的2年隨機區組試驗發現產量性狀的鈴重和衣分與環境的互作效應小，不存在母體效應，並以加性遺傳效應為主，分別占表型方差的51 . 2 %和65 . 4 % ;顯性遺傳效應所佔的比率也較高，分別為32 . 6 %和16 . 8 % .鈴重和衣分的群體平均優勢較大，分別為13 . 3 %和3 . 5 % ，達到了極顯著;鈴重的超親優勢為2 . 0 % ，不顯著;衣分為顯著的負值（ - 2 . 1 % ） .遺傳分析與雜種優勢結果一致.具體表現在產量性狀上，親本相當配製的組合雜合顯性較高，其超親優勢正向顯著，而極值親本（差異較大）所配組合沒有超過高親的.這表明親本差異小、親源關系較近的親本中仍然存在足夠的遺傳變異或某種機制以創造變異使育種取得更大的進展.相關分析表明了仍然存在嚴重的品質與產量的負相關，遺傳改良的難度較大Clustering analysis showed that plants in the genus of p. salicina could be distinguished from those in the genus of p. ameniaca ; there was some genetic relationship among p. mume, p. salicina and p. ameniaca, of which p. ameniaca was closer to p. mume in genetic relationship ; and the distance between varieties of each genus was different, with the smallest being 0. 1138 and largest being 0. 7633. the genetic distance reflects genetic relationship between tested materials. the result that varieties of each genus were close to each other in genetic relationship testified the traditional morphology - based taxonomy from the genomic dna
不同引物擴增出的帶型完全不同，聚類分析結果表明，李屬植物和杏屬植物能完全被區分開，李、杏和梅之間表現出一定的親緣關系，其中杏，梅之間的親緣關系較近，各屬品種之間都有不同的遺傳距離，最小距離為0 . 1138 ，最大距離為0 . 7633 ，遺傳距離的大小反映了材料間親緣關系的遠近，各屬內品種的親緣關系比較近，這一聚類結果從供試材料基因組dna分子水平驗證了傳統的形態學分類觀點。Its basis idea and method are that you should think the maths not a preexistance logic system, but think it is a experiment science. the student should begin with problem, use the computer. he should set up a solution project and do it himself to explore the law of maths. that is, the students must learn in experiment, learn with problem to explore and find the law of maths. there, we put the emperiment as a part of the whole advanced mathematics. during the experiment, we acquired that the student must use one maths software at least. we introduced the maple sofeware
它的基本思想和方法是不把數學看作成先驗的邏輯體系，而把它看作「實驗科學」 ，從問題出發，藉助計算機，通過學生親自設計和動手，體驗解決問題的過程，從實驗中去學習，探索和發現數學規律。我們在高等數學教學過程中進行數學試驗，把它作為了高等數學的一部分。在實驗過程中，我們要求學生至少掌握一種數學應用軟體。Based on the morphological and phytochemical investigations, comparative studies on the antidepressant action of the ethanol extracts of hypericum perforatum linn > h. faberi r. keller and h. sampsonii hance ( sect. hypericum ) were conducted. the forced swimming and mouse - tail suspension tests in mice show that the extracts from these 3 species have antidepressant actions
在形態學研究和化學研究基礎上，對貫葉連翹及與之親緣關系相近的貫葉連翹組揚子小連翹、元寶草醇提物的抗抑鬱作用進行比較研究，採用小鼠尾懸掛試驗、強迫游泳試驗，結果表明三者均可對抗小鼠的失望行為，具有抗抑鬱作用。分享友人
