不能交换

If the operator does not grasp now market development this trend, cannot manage the modernized management to take develops diligently goal, if the operator does not grasp the market development this to be unable to cause the management detachably now, the source of wealth to be luxuriant, uses the advanced data bank administration software management, may solve puzzle enterprise information questions and so on work security, reliability, single plane/Uses under the advanced number network environment the running rate to be quicker, the performance is stapler, data exchange speed even more quickly, accurate, running rate to be possible to hold the many client side concurrent operation quickly.

在此基础上现在有很多的商品批发商还是用手工出货，进货，计算，统计，那么成本方面和效率方面一定不高，如果达到以最小的成本得到最大的利润，那么一定需要选择科学，自动的管理方式。经营者如果不掌握当今市场发展的这一走向，就不能将现代化经营方式作为努力开拓的目标，就无法科学经营管理，让自己财源茂盛。如果采用先进的数据库管理软件管理，可以解决困扰企业信息化工作高成本、低产出、安全性、可靠性等问题，计算机/网络的管理软件运行速度快，性能更稳定，数据交换速度更加快捷、准确，可容纳多个客户端同时操作。

We improve the protocol for signing contract 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 can't gain more information about the whole signature by accumulating the more 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 doesn't care about the advance quit of the other party, because he has gained the whole signed information.

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，参与者分别公开承诺，并得到对方对合同的完整签名；在公开承诺时，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，同时本文也利用多方安全计算的结论证明了该协议满足终止公平性。

The present research work focuses on two aspects. On one hand, the most successful alkaloid-derived ligands have been attached to a soluble or insoluble support covalently, but additional OsO〓 is necessary to maintain the consistent catalytic activity during the reuse of supported chiral ligand in the next AD reaction. On the other hand, immobilization of osmium tetroxide based on microencapsulation, ion-exchange techniques, and osmylation of resins has made it possible to recover and reuse of the osmium, but failed to recover the chiral ligand at the same time.

目前的研究主要集中在两个方面：一方面，将手性配体共价键合到不溶或可溶性载体上制成负载手性配体，但在重复使用负载配体时必须补充OsO〓，才能保证催化活性不降低；另一方面，将OsO〓包裹在高聚物微囊内，或运用离子交换技术或共价键合的方法将OsO〓固载在树脂、硅胶或层状双金属氢氧化物材料上，但手性配体却不能同时回收。

Eighty percent of the potassium taken up by cotton was from nonexchangeable potassium of the soil.Both the pot and the field experiment showed a same result that the content of soil nonexchangeable potassium will no longer decrease when it reached a certain level,while nonextractable potassium with 1 mol/L HNO3 will continue to decline.

棉花吸收的钾素中有80%来自于土壤非交换性钾，盆栽生物耗竭与连续种植10年棉花的田间土壤，具有相同的结果，土壤交换性钾在下降到一定程度后不再下降，而1mol/LHNO3不能提取的钾一直在下降。

Some of the neuroeconomics topics we are studying at Caltech include: Why people find it difficult to attach dollar prices to goods that are not traded (like environmental harm, health, and safety); whether having too many choices actually makes people less happy with what they own; thinking strategically about what other people will do, when you are trying to outguess them or cooperate with them; how people behave when they fear economic unknowns (like starting small business or investing in countries with unstable political systems); deception in bargaining; the neural foundations of intrinsic motivation for working hard, like intellectual curiosity; and moods and investor sentiment in stock markets.

目前我们在加州理工学院从事神经经济学研究的课题项目包括：为什麽人们认为给不能用以交换的商品(如环境损害、健康、安全)定价格是困难的；面对太多的选择是否使人们竟然对自己拥有的现状感觉不甚愉快；当你试图智算他人或与他人合作时，从策略上考虑他们将做什麽；当人们担忧经济不可预测时（如：开创小企业，或投资于政治体系不稳定的国家），他们将采取什麽样的行为；讨价还价的骗术；努力工作的内在动机的神经基础；心态和投资者对股票市场的情绪，等等。

The theory implies that the body is capable, through energy exchange, to short-circuit the system by ingesting its own secreted body fluids to stimulate the transmutational forces within and challenge the body to transform unusable substances into usable ones.

这理论意味着，身体有能力，通过能量交换，通过喝他自己分泌的体液去短路系统去刺激转变内力和激发身体去转变不能使用的物质为能用物质。

Examples include the neighborhood fish and chip shops in the UK, Australia or New Zealand; the sandwiches sold by delis in the U.S.; and the wide range of sausage-based snacks sold from stalls in German cities.

在这个家里，一切似乎都可以用金钱来交换，包括夫妻生活。空虚、孤独的Gabrielle为了寻求刺激，和家里才17岁的小园丁发生了故事。不过，有钱人似乎可以接受一切交易，能不能接受背叛就不一定了。

If we could not do so, goods and services could not be exchanged efficiently

如果我们不能这样，商品和服务就不能有效地交换。

Compared with the exchange and mutation operation in genetic algorithm ,crossover operation becomes helpless when adaptive value of most individules in demes have little difference.The algorithm falls into local solution and can't be solved by exchange. Although mutation can make it shake off local convergence and jump out of local solution, denteric mutation may destroy the produced module that is constructive to form the optimal solution.

相比遗传算法中的交换和变异操作，当种群的多数个体适应值相差不大时交叉操作就显得无能为力，算法陷入局部解而不能由交换解决，突然变异能够使之摆脱局部收敛而跃出局部解，但是后期的变异可能破坏已产生的对形成最优解有建设性作用的模块。
