In crystal, two APC-PY trimers associate into a hexamer by face. The assembly of two trimers within this hexamer is very similar to that of C-phycocyanin and R-phycoerythrin hexamers, but the tight level of the assembly of two trimers within this hexamer is clearly not so much as that of C-PC and R-PE hexamers.

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.
盆地构造热演化力源机制数值模拟研究表明:早、中侏罗世至晚侏罗世晚期,盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果,同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关;早白垩世早期至早白垩世中期,来自东部太平洋块体俯冲作用的减弱,而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用;进入早白垩世晚期至晚白垩世早期,由于双重俯冲带中西侧俯冲作用带基本停止活动,而本区地幔热能的快速衰减则控制盆地的构造热演化;晚白垩世晚期以后,太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

In order to explain clearly the variation status of embryo from tetrapoid Robinia pseudoacacia and fully use the variation resource initiated in the sexual reproduction of TRP in the further improvement of TRP, the classification and vitalities of seed embryos from tetraploid Robinia pseudoacacia were studied. The main results are as follow. According to the cotyledon number, color and plumpness, the seed embryos of TRP could be divided into 5 types: YVT (yellow, very replete,2 cotyledons), YMT( yellow, more replete,3 cotyledons ), YRF ( yellow, replete,4 cotyledons ), GNT ( green, no-replete, 2 cotyledons ) and WNT ( white, no-replete, 2 cotyledons ).

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8~2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8~10 grade. The yield strength is reduced by 10~20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).
