中国杂交水稻技术的发展经历了三个主要的阶段:自1950年代,以袁隆平为代表的杂交水稻研究者探索出水稻杂种优势利用可行性路径,发明了籼型三系杂交水稻.在政府主导下,杂交水稻技术研发团队形成了“大协作”的科研模式,实现了三系配套关、良种选育关和制种关的技术创新.随后十年,袁隆平等发现水稻温光敏雄性不育现象并育成温光敏不育系,两系法育种从科学设想成为现实,具有明显的优越性.此后的25年,中国超级稻育种计划将常规选育、三系、两系选育方法和分子生物技术方法等现代技术统一起来.近半个世纪以来,中国的优良品种取得了突出成就,获得了巨大的经济效益和社会效益.在此过程中,社会对粮食增产的迫切需求、科研协作等因素起到了重要的推动作用.“,”Hybrid rice technology in China was developed in three stages.From the 1950s onwards,hybrid rice researchers,as typified by Yuan Longping,sought out a feasible approach to utilizing rice heterosis,and developed the three-line indica hybrid rice.Led by the government,the hybrid rice technology R&D teams adopted the research mode of“large-scale cooperation”(大协作),and accomplished technical innovations in the three-line system,selective breeding,and production of hybrid seeds.In the ensuing decade,Yuan Longping and others discovered the photo-thermo sensitive genic male sterility(PTGMS)of rice and developed PTGMS lines,turning highly advantageous two-line rice breeding from scientific vision into reality.Over the next twenty-five years,China\'s super-rice breeding program integrated the conventional,three-line,and two-line breeding methods with modern molecular biotechnology methods.For nearly half a century,China made outstanding attainments in acquiring quality strains that yielded enormous economic and social benefits.Throughout this process,factors such as urgent social demand for increased grain production and scientific research cooperation provided significant impetus.

For every simple graph G,a class of multiple clique cluster-whiskered graphs Geπm is introduced,and it is shown that all such graphs are vertex decomposable;thus,the independence simplicial complex IndGeπm is sequentially Cohen-Macaulay.The properties of
A finite group is said to be weakly separable if every algebraic isomorphism between two S-rings over this group is induced by a combinatorial isomorphism.We prove that every abelian weakly separable group only belongs to one of several explicitly given f
杨辉是中国13世纪数学著作的重要作者之一,《详解九章算法》(1261 CE)是现存杨辉最早的一部著作.13~15世纪,杨辉的这部著作在《九章算术》的流传与流行中起到了关键的作用.然而,现存的《详解》刻本残缺不全,并且包含大量舛误,这些阻碍了当代研究者对这部著作的理解.《九章算术》的方程章处理有关我们现在所视作线性方程组的问题,然而阐释《详解》中该章的文本并且恢复与方程有关的数学操作却有困难.通过细致的文本和算法分析,本文作者解释了杨辉对于“方程法”和“正负法”的理解和操作.《详解》中与“正负法”相关的一些
The concept of an HX-group is an upgrade of the concept of a group,in which a new operation is defined on the family of non-empty subsets of a group.If this new support set together with the new operation is a group,then we call it an HX-group.On the othe
For a partition λ and a prime p,we prove a necessary and sufficient condition for there to exist a composition δ such that δ can be obtained from λ after rearrangement and no partial sums of δ are divisible by p.To demonstrate why we are interested in the

Let △(φ,ψ) =(A BMA ANBB) be a Morita ring which is an Artin algebra.In this paper we investigate the relations between the Gorenstein-projective modules over a Morita ring △(φ,ψ) and the algebras A and B.We prove that if △(φ,ψ) is a Gorenstein algebra and
