Phytochromes in rice are encoded by a gene family composed of three members, PHYA, PHYB, and PHYC. Through characterizing the phytochrome mutants and wild type （WT） in terms of photomorphogenesis, roles of individual phytochromes have been preliminarily explored in regulating rice de-etiolation, flowering time and fertility. However, little information has been reported about whether or how phytochromes affect chlorophyll biosynthesis and chloroplast development in rice. In this study, we compared the chlorophyll contents of wild type and the phyA, phyB and phyAphyB mutants grown under either white light （WL） or red light （R）. The results suggest that phyB perceives R to positively regulate chlorophyll biosynthesis, while the role of phyA can be detected only in the phyB-deficient mutant. Analyses of the expression levels of genes involved in chlorophyll biosynthesis revealed that phytochromes affected the chlorophyll biosynthesis by regulating protochlorophyll oxidoreductase A （PORA） expression. The role of phyB in chloroplast development was also analyzed, and the results suggest that phyB perceives R to regulate chloroplast development by affecting the numbers of chloroplasts and grana, as well as the chloroplast membrane system.

处于高含水开发期油藏的剩余油分布主要受流体性质和岩石孔隙结构的影响,而经典数值模拟并没有考虑微观孔喉特征的影响。为此建立了描述微观孔喉特征的地层孔隙网络模型,并对构成网络的基本连线单元进行改进,使网络模型能更细致地描述油水分布特征和水驱油微观机理。利用逾渗理论计算了基于微观渗流机理的相对渗透率曲线,并将其应用到经典数值模拟计算中,实现了微观渗流机理与宏观数值模拟计算的结合。实例分析表明,利用该数值模拟计算方法得到的基于微观特征的剩余油分布更符合地下实际流体分布,其结果可为调剖堵水、化学驱提供技术参数。

为考察预制柱-叠合梁装配整体式框架节点的抗火性能,利用ABAQUS建立节点的有限元模型,采用简化弹簧模型对套筒灌浆连接件进行了模拟,模型得到了抗火试验结果的验证。利用上述模型,分析了梁荷载比、柱荷载比、梁柱线刚度比、轴向约束刚度比的影响。研究表明:梁荷载比、柱荷载比和轴向约束刚度比对节点的抗火性能有较大影响;随着荷载比的增大,节点的耐火极限呈下降趋势;轴向约束刚度比减少了柱端位移,对节点抗火性能存在有利影响;接近耐火极限时,节点转角增长明显加快,并在较短时间内失去了承载能力,破坏具有一定的突然性。

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
