So before applying Mather's theorem of connecting orbits to concrete Hamiltonian system, we have to check whether the set W〓 is empty or not, and which cohomology classes are C-equivalent. In present paper, by investigating the topological structure of action minimizing sets near a co-dimensional one torus which is preserved under generic perturbations and becomes hyperbolic in nearly integrable Hamiltonian system.

与传统的Poincaré-Melnikov方法相比，我们方法明显优越之处在于，一方面我们的方法不仅可以得到双曲环面之间的异宿轨道，而且当该环面附近的其它环面破裂时，可以得到不同Mather集之间的连接轨道，另一方面，我们把异宿轨的存在性的证明转化为双曲环面极小同宿轨的某种弱孤立性的证明，所需条件比Poincaré-Melnikov方法弱得多。

Let G be a double-outer plane graph, V, E, F be the set of points, edge and face, a plane graph G is k-total colorable, if the elements of V E can be colored with K-colors, any two distinct adjacent or incident elements receive different colors.

设G是一个双外平面图，V，E，F分别为双外平面图G的点集，边集和面集。G的全色数X是使得V∪E中的任意两个相邻或相关联的元素间均染不同颜色的最少颜色数。

Results The postoperative follow-ups with 6～24 months revealed good results of the symmetrical nasal wings and nostrils and centered nasal columella.

结果：本组病例术后双侧鼻翼及双侧鼻孔均对称，鼻小柱居中，随访6～24个月，疗效均满意。

The process technique and production testing of acidity cure agaricus bisporus with commix soup of acetic acid glacial and common salt was studied.

研究采用冰乙酸和食盐的混合液作为汤汁的双孢蘑菇酸盐渍生产工艺、产品检验等，结果表明，冰乙酸浓度2%、食盐浓度8%～12%是双孢蘑菇酸盐渍的最佳生产工艺条件。

After investigating the evolving of tax systems in the world and the rising of income tax in developed countries, the author suggested the way to optimizing Chinese tax revenue structure is to set up a two-main-body tax system with turnover tax and income tax. The conceived outline is to augment the income taxation, to adjust the comparative proportion between turnover tax and income tax, and hence to change the distorted tax system and set up a two-main-body one, in which turnover tax and income tax can function congenially and complementally.

在分析成因、指出弊端和改革必要性后，本文通过对税制演变的规律总结和发达国家所得税上升为主体税种的过程考察，提出优化我国税种收入结构的方向是建立双主体税种结构，总体思路是在稳定流转税收入的情况下，增加所得税的规模及在税收收入中的比重，以动态的方式改善商品流转税和所得税的相对比例，改变我国税种收入结构失衡、税制功能扭曲的现状，构建一个流转税和所得税结构协调、功能互补的双主体税种结构。

According to the direct ratio relationship in a certain range between the color degree of the organic solvent with Pb^2＋ and dithizone in the complex compound and the amount of the lead, the amount of the lead can be rapidly determined by way of the visual colorimetry.

再加入双硫腙的三氯甲烷溶液，根据Pb^2＋离子与双硫腙生成的配合物在有机溶剂中的颜色深浅与铅含量在一定范围内成正比的关系，用目视比色法即可快速判断出样品中的铅含量。

After the sample is dissolved and the disturbance eliminated, then dithizone and chloroform solution are added in the sample. According to the direct ratio relationship in a certain range between the color degree of the organic solvent with Pb2+ and dithizone in the complex compound and the amount of the lead, the amount of the lead can be rapidly determined by way of the visual colorimetric.

样品消解并消除干扰离子后，加入双硫腙的三氯甲烷溶液，根据铅与双硫腙生成的络合物在有机溶剂中的颜色深浅与铅含量在一定范围内成正比的关系，用目视比色法即可快速判断出样品中的铅含量。
