粘粒載體 的英文怎麼說
中文拼音 [niánlìzǎitǐ]
粘粒載體
英文
cosmid vector-
A gene library of psedomonas fluorescens g2 was constructed in the cosmid vector pla2917 using e. coli jm109 as the host strain. two recombinants, pgr3 and pgr7, which can confer glyphosate resistance ofe. coli jm109 were identified from the selective medium containing 10mm glyphosate
以粘粒pla2917為載體、大腸桿菌jm109為受體菌構建熒光假單胞菌g2的基因組文庫，在含有10mm草甘膦的固體選擇培養基上篩選出兩個耐受克隆pgr3和pgr7 ，插入片段分別為7kb和11kb 。In the dry sliding experiments of composites, friction coefficients decrease with the loads. plastic deformation happens in the worn surface where the element of fe is found, so pam microfibrils support part of the load and prevent the further deformation
低速低載時，試樣磨損表面出現塑性變形，在復合材料的磨損表面還發現fe元素的存在，表明pam微纖承受了部分載荷，阻止了基體的粘著轉移，此時磨損機理為磨粒磨損和粘著磨損。In this paper, with complete calculation micro - mechanics method, mass concrete was taken as three - phase composites, which consists of mortar matrix, aggregate and bond between matrix and aggregate. with nonlinear finite element method, the simulation of static and dynamic mechanics performance of the uniaxial compress concrete specimen of dongjiang arch dam and simple supported beam specimen of xiao wan arch dam was studied by means of the software of msc. marc. the number of all kinds of mortar matrix was calculated according to grading of aggregate of three graded concrete and walraven function
本文採用完全細觀計算力學方法，將大體積混凝土在細觀層次上看成是由粗骨料顆粒、硬化水泥砂漿及其二者之間的粘結界面組成的非均質復合材料，採用非線性有限元方法，在對大型商業有限元軟體? msc . marc二次開發的基礎上，對東江拱壩的三級配混凝土軸壓試件、建設中的小灣拱壩三級配混凝土梁試件在靜、動荷載下的力學性能和破壞過程進行了數值模擬。
