The following statements are proved:. A is equivalent to a diagonal matrix if and only if A is similar to a diagonal matrix.. If R is an APT ring, then A can be uniquely diagonalized as diag{e1,..., en} and ei divides ei+1.. R is an APT ring if and only if R/I is an APT ring, where I is a nilpotent ideal of R.

本文证明了以下结果：A相抵于一对角阵当且仅当A相似于一对角阵；若R是一APT环，则A在相似变换之下可唯一地化为对角形diag{e1，…，en｝，这里ei整除ei+1；R是APT环当且仅当R/I是APT环，这里I是环R的一幂零理想。

Luhrmann's soft-filtering lens — a man being trampled to death by rampaging cattle or a city being annihilated by bombing Japanese warplanes — the calamities of history are merely colorful grist for his main interest, the romance between a wilted English rose, Lady Sarah Ashley, and an itinerant Australian cattleman, the Drover. The lady and the tramp meet soon after she lands in Australia to track down her cattleman husband, whose early murder sets all the narrative pieces in place. Initially intent on selling her property, including 1,500 head of cattle, Sarah soon transforms into a frontierswoman, seduced by Nullah's smile and the majestic valleys and peaks of both the land and of the Drover's musculature.

If two parties want to sign a contract C over a communication network, they must "simultaneously" exchange their commitments to C Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate simultaneity by exchange partial commitments in a piece by piece manner The party of secondly sending commitments may have a slight advantage; a "fair" protocol must keep this advantage within acceptable limits The protocol for signing a contract is improved based on the research result of secure multiparty computation In this protocol, the parties obliviously transfer the signed bit and the committed bit; the other parties can prove the validity of this bit based on the confirming sub protocol, but he cant gain more information about the whole signature by accumulating the signed bit or the committed bit After the parties exchange the whole signed information, they declare the commitment about the signature respectively, and gain the whole signature of the other party At this moment, the party doesnt care about the advance quit of the other party, because he has gained the whole signed information Finally, it is proved that this protocol is quit fairness

在网络环境中解决合同签订问题需要保证信息交换的同时性，以前提出的协议都会给第 2个发送者部分计算特权，利用不经意传输协议则可以解决这个问题在协议执行过程中，参与者将合同的签名位以及他对签名位的承诺不经意传输给对方，对方可以利用验证子协议证明该位的有效性，但是他却不能通过位交换次数的增加获取更多的完整签名的信息；在完成签名位的交换之后，参与者分别宣布承诺，并得到对方对合同的完整签名；在宣布承诺时，协议参与者已经获得全部的签名内容，要么是签名位，要么是对方对该位的承诺，因此参与者并不需要担心对方提前终止协议在文章的最后利用多方安全计算的结论证明了该协议满足终止公平性1 引言两个参与者A和B想要通过网络协商签订合同C 为了保证公平性，参与者必须同时交换自己对合同的签名，然而在实际的网络环境中，想要完全同时地交换对合同的签名是不可能的，他们必须将签名分成若干块依次地执行，以保证大致的同时性但是这种方法依然存在着问题

What bothered Torre most was Rodriguez's seeming obliviousness to how badly he was playing. In June, for instance, hitting coach Don Mattingly ordered Rodriguez into the cage and sternly lectured him on the flaws in his swing, which Mattingly thought A-Rod had been unwilling to address."An intervention," Mattingly called it."He got to a pretty good point with , but it lasted only a few days and he went right back to where he was."

最为困扰著Torre的是， A-Rod似乎没有意识到自己的表现有多麼糟糕，举例来说，今年六月的某一天，打击教练Don Mattingly要求A-Rod进入打击练习区，然后严厉地指出A-Rod挥棒动作中的瑕疵，当时他认为A-Rod本人并没意识到这些问题，而自己有义务帮他做些调整，"当时他的挥棒动作的确有所改善，不过这样的认知和调整只持续了几天，他又回到了老样子"

Interestingly, corporate managers have no trouble understanding that point when they are focusing on a business they operate: A parent company that owns a subsidiary with superb long-term economics is not likely to sell that entity regardless of price."Why," the CEO would ask,"should I part with my crown jewel?" Yet that same CEO, when it comes to running his personal investment portfolio, will offhandedly - and even impetuously - move from business to business when presented with no more than superficial arguments by his broker for doing so. The worst of these is perhaps,"You can't go broke taking a profit." Can you imagine a CEO using this line to urge his board to sell a star subsidiary?

Nor was the party over in 1938 for an investor： Though the $40 invested in 1919 in one share had turned into $3，277 by the end of 1938， a fresh $40 then invested in Coca-Cola 16 有趣的是企业经理人在认定何者才是自己本业时，从来就不会搞不清楚情况，母公司是不会单纯因为价格因素就将自己旗下最优秀的子公司给卖掉，公司总裁一定会问，为什么要把我皇冠上的珠宝给变卖掉，不过当场景转换到其个人的投资组合时，他却又会毫不犹豫地，甚至是情急地从这家公司换到另一家公司，靠的不过是股票经纪人肤浅的几句话语，其中最烂的一句当属，你不会因为获利而破产，你能想象要是一家公司的总裁用类似的方式建议董事会将最有潜力的子公司给卖掉时，就我个人的观点，适用于企业经营的原则也同样适用于股票投资，投资人在持有一家公司的股票所展现的韧性应当与一家公司的老板持有公司全部的股权一样。

According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall. The other is Z or ring shaped a-c 90°domain boundary along {010} direction, and the displacement vector 〓 runs along 〓 direction.

根据界面相对于样品中(100)观测面取向的不同，90°畴可分为两类：一类为薄透镜片状或环状的a-a90°畴，其界面平行于{110}，多数不带电，由消光规律可确定其位移矢量平行于畴界面与自发极化所在平面的交迹，即，〓方向，而从包含畴界的选区电子衍射图可知，这种不带电的90°畴界两侧存在微小的取向差，其界面两侧的结晶学关系为以界面法线为二次轴的旋转关系；另一类为Z状或环状的a-c90°畴，其界面平行于[010]或[001]，相应的位移矢量为〓方向。

D modal tuning: D-A-d-g-a-d' and D-A-d-a-d'-d' Popularised by Davey Graham, who had been inspired by Arabic oud tuning while living in Morocco. D modal tuning D-A-d-g-a-d' is now encountered in Celtic music and contemporary music.

形式调弦D D-A-d-g-a-d' and D-A-d-a-d'-d'由Davey Graham推广起来的调弦，这个调弦是他在摩洛哥时从阿拉伯音乐调弦中得到的灵感，形式和弦D D-A-d-g-a-d'与赛而特音乐及现代音乐中常常可以遇到。
