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。

In our modern health-care-industrial-complex — and I'm talking about the bureaucrats who try to herd you into the cheapest cattle car available, not the nurses and doctors who are on the front lines — the emphasis is neither on health nor care, but on the bottom line.

我正与官僚们谈论，这些人一味地尝试将你推进最便宜的牲畜车上，而不是在手术前线上的医生和护士。重点不在健康和看护上，却是在最底线。

In the first successful liver transplant, the doctors had told him that he should convalesce, but he is still prepared to resume as soon as a film, in addition to performing their love, economic pressures, personal burden is also an important reason, and Fu Biao dies, The villa can be retained has become a problem.

在第一次肝移植手术成功后，医生曾嘱咐他应该静养，但是他还是准备尽快复出拍戏，除了对表演本身的热爱外，经济上的压力、人情上的负担也是一个重要原因，而傅彪去世后，这套别墅能不能保留也成了一个问题。
