While that system was first described in a paper by Diffie and me, it is a public key distribution system, a concept developed by Merkle, and hence should be called 'Diffie–Hellman–Merkle key exchange' if names are to be associated with it.

虽然这个系统首先是在我和Diffie的一篇论文中描述的，但是这却是一个公钥交换系统，是Merkle提出的概念，因此如果加上他的名字，这个系统实际上应该称为'Diffie–Hellman–Merkle密钥交换'。

Secondly, its deep research and design is finished about some key technologies of the software for the system. These include the high capability of multi-layer database system, the software of intellectualized electrical simulation drawing, the interlinkage and the real time data exchange of the heterology system, the data exchange with external and the share platform base on web pattern, and the software of system supervising. The software platform is made to fell in with system demand on the basis of current developmental tendency of technique.

域，体：进行加法和乘法两种运算的一组数，满足如下条件，即乘法分配律同样适用于加法分配律，各数在做加法和乘法两种运算中可相互结合并交换，但在乘法中不可交换的加性恒等幺元除外

Make promotion more, can exchange a link more, increase external link, it is to mix others exchange link, 2 it is to go of Baidu stick, know and other places just sends a card, 3 it is stationmaster of much associate with, can take a few your websites sometimes, 4 it is to arrive above A5 hair post, there is link above idiograph (the card that here does not encourage everybody to send a few rubbish in A5, can help others) as far as possible.

多做推广，可以多交换链接，增加外部的链接，一是和别人交换链接、二是去百度的贴吧、知道等地方发帖子，三是多结交站长，有时可以带一些你的网站，四是到A5上面发帖，个人签名上面有连接(这里不鼓励大家在A5发一些垃圾的帖子，尽量能够帮到别人)。

It is a natural generalization of the notion of implicative ideals in BCK algebras.

证明了BCI代数的一个非空子集是BCI关联理想当且仅当它既是BCI交换理想又是BCI正定关联理想，从而揭示了这三类理想之间的内在联系，并将BCK代数中知名论断：BCK代数的一个非空子集是关联理想当且仅当它既是交换理想又是正定关联理想，推广到BCI代数上去。

With the investigate of the strict restrict of the personal foreign trade, strict system of toll-gate,high impost and the recordation of come-and-go peoples from the multi-strip which excavated in XuanQuan,DunHuang,we think that the viewpoint of Mr YuYingshi and Mr Michael Loewe were need to deliberate.

这样一种交换，汉朝非但不能从经济上获得利益，反而要背上沉重的负担，从纯经济的角度而言是不划算的，并不是一种纯商业意义上的交换，就此而言，在汉朝的对外交往中，纯粹的商业贸易不能说没有，至少相对于朝贡往来而言是比较少见的。
