On the rhombohedron face {1011}, Dauphine twinning showed different shapes of etching pits between individuals, because rhombohedron positive form {1011} and negative form {0111} appeared on both sides of twin partition line, while Brazil twinning showed symmetry plane between the irregular triangle etching pits of individuals. On the trigonal prism section 11(average20, Dauphine twinning showed different shapes of etching pits between individuals, because trigonal prism positive form {1120} and negative form {2110} appeared on both sides of twin partition line, while Brazil twinning should show symmetry plane between the ellipse or quadrilateral etching pits of individuals, which was not observed.

菱面体{1010}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是菱面体正形、菱面体负形出露处，导致蚀坑形状不同；菱面体{1011}面上存在巴西双晶处，不规则三角形蚀坑形态的方位关系为对称面关系；三方柱切面{1120}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是三方柱正形、三方柱负形出露处，导致蚀坑形状不同；三方柱切面{1120}面上存在巴西双晶处，椭圆形或四边形蚀坑方位应为对称面关系，但实验中未见到。

Syringe aspiration: At the up-left and right-down two regions, needle with 20 mL in volume used for extracting fat was used.

电动脂肪抽吸法：在左下、右上两个区域，用电动脂肪特制抽吸管置入待抽吸区域皮下脂肪组织内，调节负压为-75kPa，防止漏气以保持相对稳定的负压，往返抽动抽吸管12次，抽吸脂肪约30mL。

S:The author applies row matrix to extend concept of exclusive or from the set of nonnegative integer to the set composed of nonnegative integer array.

利用行矩阵，把异或概念从非负整数集推广到非负整数组构成的集，给出了高阶异或的概念，得到了关于高阶异或的一个性质定理，建立了谭勇先生提出的高次坑棋的数学模型。

At that night, I heard the negotiation between my father and mother when it happened in his sanctum.

那一晚，我听见父亲在书房里用电话与我的生母谈判，他说你这个做母亲的也该负负责任，儿子我养了这么久，你也是时候接手了。

Under the current schedular tax system, the income generated at different times shall not offset each other, that is to say, all income shall be taxed, and no tax is imposed if no income is generated.

由于国家目前对股票转让所得暂不征收个人所得税，国家税务总局在研究股票转让所得的申报时考虑到：个人在一个纳税年度内可能频繁发生多次股票交易，要求其逐次记载股票转让所得，无疑将增大个人自行纳税申报难度；同时考虑到在一个纳税年度内股票交易盈亏具有不确定性，所以，在明确股票转让所得申报口径时规定，一个纳税年度内股票转让所得与亏损盈亏相抵后的结果为正数的，应统计在12万元之内；考虑到一些纳税人的其他应税所得项目已经超过12万元，本身已属于高收入群体，对于一些高收入者的股票转让盈亏相抵结果为负数的，为避免炒股的"负盈余"对已超过12万元的其他各项所得的冲抵，加强税源监控，我们规定"负盈余"按"零"申报。

In chapter 4,we consider the existence of harmonic function in negative sectional curvature manifolds.we get that,if Ricci ≥-C(1 + r~2)r =ρ(O.x, then there have non-canstant bounded harmnic function in negative sectional curvature manifolds.

第四章考虑负曲率流形上调和函数，得到了在Ricci≥-C(1+r~2)其中r=ρ的负曲率流形的调和函数的存在性。

Based on the Seidel sums formulae of thin lens, four types of NIM thin lenses free from partial primary aberrations are designed with specific parameters and given redundant aberration coefficients.

通过对单块负折射率介质薄透镜的像差特性分析，我们提出了四种只有利用到负折射率介质才具备的可消除部分初级像差的单块薄透镜系统，并给出了相关的系统结构参数和冗余的初级像差表达式。

In this thesis, we introduce three indexes that are used to evaluate the main business firstly. Theyre profit of main business, cashflow of main business and integrated index of main business. Then, we construct a series of regression models of assets structure with profit of main business and cashflow of main business, which signalize the current assets and the fixed assets help them; the long-term investments hinder them; the other assets help or hinder them uncertainly, and even have nothing to do with them sometimes. Finally, we construct the regression models of assets structure with integrated index of main business, and put forward a method to optimize the assets structure.

本文首先将主营业务指标分为主营业务利润、主营业务现金流量与主营业务综合指标；然后，通过构建资产结构与主营业务利润、资产结构与主营业务现金流量回归模型，发现流动资产、固定资产对主营业务利润和主营业务现金流量为正影响，长期投资对主营业务利润和主营业务现金流量为负影响，其他资产对主营业务利润和主营业务现金流量影响时有时无，时正时负；最后，在此研究基础上，构建资产结构与主营业务综合业绩指标回归模型，并提出优化资产结构的方法。
