,if it has a positive orbifold line bundle,then there exists a positive integer N,such that M can be embedded into CPN topologily.

证明了orbifold嵌入定理在高维的orbifold上成立,即对于一紧致复orbifoldM,若其上有一个正定的线丛,则存在正整数N使得M可以拓扑嵌入到CPN。

Based on the research fruit of "Auxiliary Angle Method", this paper puts forwards the theoretical plot for setting up a set of performance and design diagram atlas of offset type and type planar crank and slider mechanisms ; and develops a software PCASMDC capable of automatically producing the diagram atlas; based on above mentioned diagram atlas, this paper draws a lot of conclusions.

Let M be a normal variety of dimension n with terminal singularities,L an ample line bundle on M,the effective value of(M,L) beτ = uv(u,v are coprime integers),��:M→X be the nef-value morphism of(M,L),and let F be a general fiber of��.

设M是有末端奇点的n维正规代数簇,L是M上的丰富线丛,(M,L)的数字有效值为τ=uv(u、v是互素的正整数),��:M→X是由(M,L)决定的nef-值态射,F是�澋囊话阆宋�。

Let L be an ample line bundle on M.

设M是有末端奇点的n维代数簇，L是M上的丰富线丛，φ：M→X是由(M，L)决定的nef-值态射，正有理数τ=u/v是(M，L)的nef-值，这里u和v互素。
