证明

Paul Kreutzer: I can not answer this question, because it belongs to an immigrant visa category, I recommend the applicant with the United States Consulate General in Guangzhou, contact the immigration office.

网友：据说申请签证，是说去商务考察，如果说旅游和探亲更容易，这是真的吗？主持人：我想不少的朋友都想得到证明，让在美国的商业伙伴给予证明，可能是出于这方面的考虑，是这样的吗？

In this paper, the Lagrange interpolation formula asked a class function expression question, the determination function to the higher mathematics in the elementary mathematics in some value scope question, the equality proof question, the multinomial factorisation question, to ask to have the Finite series to pass the formula question, the certificate any n function at will n+1 different spots function value maximum value minimal problem and so on six aspects should serve as the simple introduction, and has separately made the comparison with these six aspects elementary mathematics method, thus solved some operation problems in elementary mathematics.

摘要本文对高等数学中Lagrange插值公式在初等数学中的求一类函数表达式问题、确定函数在某点的取值范围问题、恒等式的证明问题、多项式的因式分解问题、求有穷数列的通项公式问题、证明任一n次函数的随意的n+1个两两不同点的函数值的最大值的最小值问题等六个方面的应用作了简单介绍，并与这六个方面的初等数学方法分别作了比较，从而解决一些初等数学中的运算问题。

This paper describes the content of the theorem, and theorems are given two proofs, cite the Lagrange mean value theorem in the mathematics major applications, including that inequality, identity, Limit, determine monotonicity, root The existence of such.

本文简要叙述了定理的内容，并且给出了定理的两种证明方法，例举了拉格朗日中值定理在数学中的主要应用，包括证明不等式，恒等式，求极限，判断单调性，根的存在性等。

Theorem of mean significance: The application derivative research function's nature wants directly or indirectly with the aid of Yu Zhongzhi,Specially Lagrange theorem of mean,Here is mainly from the equality proof, the inequality proof, existence asks some limits, the determination equation root and so on five aspects to carry on the discussion,so, The theorem of mean is transforms as the function in the sector research important tool, Must bring to the enough attention in the middle of ours study and the teaching.

中值定理意义：应用导数研究函数的性质都要直接或间接地借助于中值，特别是拉格朗日中值定理，这里主要是从等式的证明、不等式的证明、求一些极限、判定方程根的存在性等五个方面来进行讨论，因此，中值定理是转化为函数在区间上的研究的重要工具。在我们的学习与教学当中要引起足够的注意。

It has been proved that if example set is of lattice point distribution the example set can be memorized by a fuzzy neural network, otherwise the fuzzy neural network will lost its memory.

通过定理，证明了在这种情况下，样本组可被模糊神经网络所记忆；证明了若样本组前n-1个样本和整个样本组的模糊矩阵的秩相等，则权向量不能调整，否则会使模糊神经网络"丧失记忆"。

Article 28 If the publisher, manufacturer of the software copies can't prove that the publication or manufacturing has been legally authorized, or the releaser or leaser of software copies can't prove that the copies released or leased have legal sources, they shall bear legal responsibilities.

第二十八条软件复制品的出版者、制作者不能证明其出版、制作有合法授权的，或者软件复制品的发行者、出租者不能证明其发行、出租的复制品有合法来源的，应当承担法律责任。

And the terms at the payment(how must to pay,in wich account).About the certificate blue,we talk about the certificate at the chamber at commerce ,who confirm you are a legitim company.

和付款条件（付款方式，通过哪个账号），关于兰卡证明，我们在财务办公室讨论关于你的证明，谁能担保你的公司的合法性。。。。

And 〓 connecting lemma,whichwas proved recently,plays a key role in the proofs of many theorems.

而最近刚刚证明的〓连接引理则在许多定理的证明中起了至关重要的作用。

In transferring patented technology of an unexpired life, the licensor should provide the licensee with a manual on the patent and a duplicate or a copy of the letters patent.

第十条供方转让有效专利权技术，应向受方提供该专利的说明书和专利证书副本或复印件。有专利权转让证明的，应同时提供证明。

VI.Where the transfer of any patent or patent application right or the license of patent right is involved in the import of technology or equipments by any foreign trade business operator, the transferrer or the licenser shall be required to show the certification documents that proves the validity of the patent or the certification materials that proves the existence of the right to apply for patents.

六、对外贸易经营者引进技术设备涉及专利权转让、专利申请权转让或专利实施许可的，应当要求转让方或许可方出示该专利有效的证明文件或存在专利申请权的证明材料。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
