We posed the concept of sufficient intersection about s(1≤s≤n) algebraic hypersurfaces in n-dimensional space and proved the dimension of polynomial space Pm(which denotes the space of all multivariate polynomials of total degree≤m) on the algebraic manifold S=s(f1,…, fs) where f1(X=0,…, f s=0denote s algebraic hypersurfaces of sufficient intersection, then gave a convenient expression for dimension calculation by using the backw ard difference operator.

Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.
世代交替又可分为两种基本类型,一为同形世代交替,即孢子体和配子体在形态大小上类似,仅在细胞学上和生理上有所不同,如石莼等;另一类型为异形世代交替,即孢子体和配子体在形态结构和大小上也有明显差异。

We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.
结果表明:花背蟾蜍蝌蚪(1)具有晶状体再生的能力,其晶状体的再生来源于虹膜背缘的上皮细胞;(2)虹膜背缘去色素是转分化的前提,主要有两种方式:一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞,巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒;另一种方式是虹膜色素上皮细胞自身释放色素颗粒;(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化,核糖体增多,粗面内质网增多,晶状体纤维分化过程中细胞核逐渐凝聚;(4)SDS-PAGE电泳发现,花背蟾蜍蝌蚪晶状体再生中相关蛋白表达顺序与有尾类蝾螈相似,蛋白表达顺序依次是β-晶状体蛋白、γ-晶状体蛋白和α-晶状体蛋白,并且后两种蛋白几乎同时表达。

Meanwhile, we highlight several research corners for future further study, the trade-offs on resource allocation within perennial plant had not been proved, the relationship of neighbor effects and reproductive allocation was still not so clear for individual plant, there was no definite conclusion on perennial plant reproductive strategy under different neighbor effects and different habitats. The relationship between reproductive allocation and sexual allocation , the cause of resource distribution in anthotaxy structure, the similarities and differences of reproductive allocation and the maintain mechanism within all kinds of reproductivest rategy need a further investigation. In addition, a molecular study is required for explaining the variation mechanism and the biological meanings on seed size research.
