 在隐性高秆水稻"02428h"中发现1个矮秆迟熟突变体"02428ha"。该突变体与02428h相比,抽穗期延迟32d左右,表现很强的感光性;株高降低60 0cm左右,主要是倒1、倒2节间长度变短,分别缩短34 0cm和19 0cm;倒1和倒2节间...  在隐性高秆水稻"02428h"中发现1个矮秆迟熟突变体"02428ha"。该突变体与02428h相比,抽穗期延迟32d左右,表现很强的感光性;株高降低60 0cm左右,主要是倒1、倒2节间长度变短,分别缩短34 0cm和19 0cm;倒1和倒2节间的株高构成系数(各节间长度占株高的百分比)分别降低8 6和3 1个百分点;穗长缩短10 0cm,每穗一次枝梗数减少2 4个,每穗总粒数和每穗实粒数分别减少125 0粒和108 0粒,但结实率无明显差异。与02428h一样,02428ha也具有广亲和特性。 展开更多

In order to study the sliding characteristics when the cable is connected with the other rods in the transmission line structures,a linear sliding cable element based on updated Lagrangian formulation and a sliding catenary element considering the out-of-plane stiffness coefficient are put forward.A two-span and a three-span cable structures are taken as examples to verify the sliding cable elements.By comparing the tensions of the two proposed cable elements with the existing research results,the error is less than 1%,which proves the correctness of the proposed elements.The sliding characteristics should be considered in the practical engineering because of the significant difference between the tensions of sliding cable elements and those of cable element without considering sliding.The out-of-plane stiffness coefficient and friction characteristics do not obviously affect the cable tensions. 展开更多
