In this paper, firstly, the embeddability of near-triangular graphs on the orientable surface is studied. By using Petersen's Theorem about 1-factor, we first prove that for a near-triangulation on the orientable surface, its geometry dual graph has a 1-factor; then after a procedure of operation leaded by the 1-factor, we show that if a graph G triangulates some orientable surface S_g, then G has a near-triangular embedding in S_h for h = g,g + 1,...,β(G/2」, where β is the Betti number of G. Hence we obtain a conclusion: A near-triangulation of the orientable surface is upper-embeddable. As a generalization, a class of near-quadrangulation is studied, and similar results are obtained.
本文首先研究了近三角剖分图的可定向曲面嵌入性质,通过运用Petersen关于1-因子的定理,首先证明了对于可定向曲面上的三角剖分图,其几何对偶图具有1-因子;然后在1-因子的导向下,通过做一系列增加亏格的手术,证明了如果一个图G三角剖分可定向曲面S_g,那么G可以近三角剖分可定向曲面S_h,这里h=g,g+1,…,「β(G/2」,β是指图G的Betti数,从而得出推论:可定向曲面上的三角剖分图是上可嵌入的,作为推广,又研究了一类近四角剖分图的可定向曲面嵌入性质,并得到类似的结论。

On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

According to alternation of reorganized-KMT "s class nature what the Comintern and Sdalin defined and KMT "s authentic class nature, we"ll find the inner coincidence between the three, KMT "s class nature what the Comintern defined, Sdalin"s "Three Stages Theory" and errors of "Left deviation in the Agrarian Revolutionary War. They have the same fault: on the theory of Chinese bourgeoisie. Comintern looked on Kuomintang as an organzation of united front, which cut apart the close relationship between Kuomintang and the boureoisie, and then inevitably led to a long-standing mistaken concept, this is, confusing the large boureoisie with the national boureoisie and the petty boureoisie. Therefore, as the large boureoisie betrayed the revolution, Comintern regarded the national boureoisie and the petty boureoisie as the underminer of the organzation of the united front, and then struck a heavy blow at then.
考察梳理共产国际、斯大林对改组后国民党性质的判定及其变化和国民党的真实阶级性质可知,共产国际对国民党性质的判定、斯大林"三阶段"论和土地革命战争时期中共党内的历次"左"倾错误三者之间,前后相续,一以贯之,具有内容上的共通性和逻辑上的连续性,它们共同的要害是共产国际、斯大林有关中国资产阶级理论的错误,一是共产国际混淆在半封建半殖民地中国的带买办性的大资产阶级与民族资产阶级,二是把民族资产阶级的妥协与革命的两面性机械地认定为革命与反革命的"两段性",认为中国资产阶级必然要叛变革命。
