不能解决问题的

In fact most Apriori which has gained association Rules suppose whither time or place is effective for ever, but this can"t solve some impersonal problem in morden life, iradionary association Rules in a general way can answer some question for example, there are 90 percent people buy sugar of who buy creamery ,but they can"t answer such question for example the people who buy creamery, but they cant answer such question for example the people who buy creamery of counter one today but there are 90 percent will buy sugar of counter two, moreover, such problem sometimes is the person of decision-making concerned thing because many things have relation with the factor of time and space, so it need consider the factor of time and space in date.

大多数算法得到的关联规则事实上都假定无论是时间还是地点都是永远有效的，但这并不能彻底解决现实生活中的许多客观问题。传统的关联规则一般可以回答诸如"购买了牛奶的人有90％购买了糖"之类的问题，但是不能回答"今天购买了柜台1中牛奶的人明天有90％购买了柜台2中的糖"之类的问题，而这类问题也往往是决策者在实际中所关心的。

The air vessel works through twice air releases, solving the problem of inconstant air supply in process of cotton opening and blending. Test and application proves that the multifunctional air vessel can solve the problem of block up caused by the uniaxial cotton opener, keeping smooth operation of the production including effective dust removal, clog and iron seperation, avoiding the disadvantage of the former units including the sporadic cutover, simplifying the blow card flow, thus reinforce quality of the card sliver and the resultant yarn.

If it is so easy to economise on spectrum, Mr Mittal says, then perhaps the government's own phone companies, BSNL and MTNL, would like to surrender some of their spare capacity and show the rest of the industry how to make do with so little.

Mittal先生表示，如果政府觉得解决频段问题很简单的话，政府可以让政府自己的电信公司BSNL和MTNL试一试，他们可以交出多余的频段，然后让大家看看能不能用很少的频段解决问题。

In general, the design work with traditional measures is done by hand, which cannot meet the needs of the technology and manufacture. So the author has developed a CAD hydraulic design software fit for lower specific speed axial flow runner, which is easily operated by users.The main research work of this paper is as follows:1 Analyzing the main reason of axial flow power station cannot work well under littler volume of flow in some season and putting forward an improving scheme, pointing out the characters of design under abnormal factors.2 Combined with the development of the industry in our country, the abnormal hydraulic design method of propeller turbine is discussed based on present literature, data and experiment results.3 Guided by the design method of software engineering, a suit of hydraulic design software of Lower Specific Speed Axial Flow Runner is programmed by the object-oriented programming language Visual Basic and a straightforward, concise and standard Windows human-computer dialogue interface is designed for the system, which makes the operation of the system very convenient.4 ActiveX Automation technology is adopted as the interface with AutoCAD and the hydraulic drawings are edited, modified by AutoCAD until hydraulic model drawings according with the demand of engineering practice are output.5 To resolve practice problem, the author has designed a lower specific speed axial flow runner for Duowa Power Station through an example.

The influence of some rnodified genetic algorithms on searchspeed is also examined. Some genetic operations suitable to the optimization technique areobtained, therefore, a novel way of solving a class of optimizations of functions that cannot be realized using the method of steepest descent is proposed.

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

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

在强对抗的攻击性防守下中国队不能解决好进攻的问题是世锦赛失利的最主要的原因之一；中国队的快攻次数与对手的差异具高度显着性，成功次数的差异具显着性，得分的差异具高度显着性，断球后发动快攻的差异具显着性；得分主要集中在接球得分、单打得分、和罚球得分这三个方面，得分手段单一而且集中；战术进攻与对手呈差异有高度显著性，作为主动进攻的罚球和争夺篮板球都比对手低；抢断与对手的的差异具显着性，进攻成功率与对手的有一定的差距，进攻效率的差距更大；2分球的投篮次数与对手的具有高度显著性差异，命中率比对手稍高一点，3分球投篮次数相当，命中率具有显著性差异；中国队的前场篮板球与对手相比具有显著性差异，但是二次进攻得分却比对手略高一点；中国队与对手的助攻相比有显著性差异；中国队的抢断与对手相比具有高度显著性差异；中国队的失误与对手相比具有高度显著性差异。

However, although it has the reliability which like on states high, antijamming ability stronger, but works as production environment is too bad, electromagnetic interference specially intense, or installs uses is improper, possibly creates the program error or the operation mistake, thus produces inputs by mistake and causes outputs by mistake, this will be able to create the equipment out of control and the disoperation, thus will not be able to guarantee PLC the normal operation, will have to enhance the PLC control system reliability, on the one hand will request PLC to produce the factory to enhance the equipment the antijamming ability; on the other hand, in the request design, the installment and the use maintenance cause highly takes, coordinates to be able in every way to consummate solves the problem, effectively strengthens the system the resistance to interference.

然而，尽管有如上所述的可靠性较高，抗干扰能力较强，但当生产环境过于恶劣，电磁干扰特别强烈，或安装使用不当，就可能造成程序错误或运算错误，从而产生误输入并引起误输出，这将会造成设备的失控和误动作，从而不能保证PLC的正常运行，要提高PLC控制系统可靠性，一方面要求PLC生产厂家提高设备的抗干扰能力；另一方面，要求设计、安装和使用维护中引起高度重视，多方配合才能完善解决问题，有效地增强系统的抗干扰性能。
