  1. In numerical taxonomy, phenon 1 included 9 new isolated strains and 1 representative strain ( usda761 ) of b. elkanii, the new isolated strains in this phenon probably are b. elkanii

    Elkanii的模式菌株（ usda76 ~ t ）聚在一起，群內相似性為80 ，初步判定群1供試葛藤根瘤菌為且belkanii 。
  2. Results of g + c mol % test shown that all slow - growing isolates were belong to the same species. more than 70 % dna - dna homologies were determined among 4 representative strains usda6, and usda110 ( type strains of b. japonicum ). low dna homologies were detected with usda76 ( type strain of b. elkanii )

    中l習花生根瘤菌遺傳多樣性和系統發育研究g + cmol %和dna一dna同源性分析結果表明，供試花生根瘤菌代表菌株的tm和g + cmol %均小於種內變異l隔度，表明供試花生根瘤菌均屬j二一個種。
  3. The result of rflp analysis of pcr - amplified 16s rdna revealed that the rhizobia isolated from the root nodules of pueraria spp. had diversity at the level of species. the slow - growing rhizobia were divided into 7 groups on the similarity level of 90 %. group 1 included 4 new isolated strains and 2 representative strains of b. japonicum. group 2 included 1 type strain of b. elkanii and 3 new isolated strains

    16srdnapcr rflp分析結果也表明葛藤根瘤菌具有種水平多樣性，在90的相似性水平上，聚類圖把慢生根瘤菌分成7群，群1與bjponicum的模式菌株聚在一起，群二與belhanii的模式菌株聚在一起，而其它群是獨立的系統發育分支。
  4. Since piles are set into a composite foundation under an embankment it can not be directly analyzed in the plane strain way. to compute its settlement, a representative segment method is developed and used in settlement analysis of composite foundation under embankment. compared with the traditional plane strain method that needs to unreasonably suppose piles as walls, the representative segment method is more reasonable

    根據樁側摩阻力的解析解，給出了加固區壓縮量的簡化演算法；採用典型段法對復合地基沉降影響因素進行了三維有限元分析，避免了平面應變分析方法中對復合地基中樁體的不合理換算，以使計算模型在力學概念上更合理。
  5. After the evaluation of the three parameters in the proposed creep model, which is based on the large numbers of experimental measurements of concrete creep, the influential regularities of concrete filled steel tube columns under long - term loading are investigated. by dispersing time, the method of tangent modulus is adopted to study the relation of creep strain and load time. in the end, this paper took cft specimens with representative geometry and sectional dimensions as examples and adopted the proposed method as an approach to investigate the influencing regularities of many factors, which include the ratio of long - term load to strength, the slenderness ratio, the eccentricity ratio, and the intensity grade of concrete, on cft structures

    在對鋼管混凝土構件長期荷載效應的分析中，本文基於三維粘彈性理論，採用三參數粘彈性模型，提出了核心混凝土徐變的三維有限元分析理論，在總結過去大量關于混凝土徐變試驗實測結果的基礎上擬合了模型中的三個參數，並成功將其應用於鋼管混凝土徐變的三維分析計算中，得到徐變與持荷時間的關系，以典型截面形式的圓鋼管混凝土軸壓、偏壓構件為例，對軸壓比、長細比、含鋼率、偏心率以及核心混凝土等級分別進行了大量的參數分析和實驗對比研究，結果表明二者符合較好。
  6. Although belonging to the same genotype, representative strain jz1 was closed to usda110, and ha1 was clustered into the same branch with usda110, usda122 and usda127, but wc7 and sd4 were clustered independently

    Jz1等供試菌和以usda110為代表的b . japonicum親緣關系最近，序列差異小於1 ；代表菌ha1與usda110等同處於一個分枝中。
