Effectiveness scarce, demand assignability is a value of the four basic elements, demand for real estate and commodities need to have the capacity to pay, we will not, the effectiveness of commercial housing is scarce in nature and that consumers do not have sufficient purchasing power, the market value can not be achieved, the current real estate market demand can be broadly divided, using the minimum requirements, the public demand for improved housing, urbanization process needs field and offshore demand, the demand for investment or speculative demand and the housing problem is livelihood security, the need to increase public finance, but this is the need, not demand.

效用稀缺，需求可转让性，是价值构成的四个基本要素，需求是对房地产商品有需要而且具有支付能力，两者缺一不可，商品房具有效用和稀缺性，消费者没有足够的购买力，市场价值就不能实现，当前房地产市场的需求大致可分为，动拆迁的需求，市民住房改善的需求，城市化过程中的需求，外地和境外的需求，投资需求或者是投机需求，住房保障问题是民生问题，需要公共财政加大力度，但这是需要，不是需求。

These issues include: the main axis may cause a similar problem with the main axis of the fault has affected the accuracy of bending; workpiece clamping possible problem is that the workpiece center and the main discrepancies, which could lead to instability in rotating workpiece; servo motor failure: the feed system Ball Screw bending and oil do not lead to rust long run can also be caused by poor, such as the same issues.

这些问题包括：主轴主要可能引起类似问题的故障有主轴弯曲影响精度；工件装夹方面可能的问题是工件中心和主轴不一致，由此可能导致工件转动不稳；伺服电机出现故障：进给系统中滚珠丝杠的弯曲和长时间不上油导致生锈运行不畅等也可能引起相同的问题等。

Will suit the Internet bar to sprinkle the shop game hall factory to use in the movement cost your customer compared to us to calculate that this digital one month-long electrical bill over ten thousand Yuan will be a cinch the question which now this question is you most has a headache, but this plant production's environmental protection air conditioning can give you to solve this problem.above lifts the example only for everybody to refer greatly, concrete take receives the arrival of shipment material object as the standard.

客户从这几基本的公式可以算出你们现在的使用空调是多少P的一小时又是多少度电一天要开多少小时这个数字留个你们自己算吧你们一年节约下来的钱可以多少台环保空调，本工厂620－4型环保空调最好使用面积70平方一台。适合网吧洒店游戏厅工厂使用在运行的成本中你们客户比我们更会算这个数字一个月的电费上万元不在话下现在这个问题是你们最头疼的问题，但本工厂生产的环保空调能给你们解决这问题。以上举的例子只供大家大该参考一下，具体以收到货实物为准。

The stickiest issue is building a directory of digital certificates.this directory holds the certificates needed to encrypt messages to a recipient.internally,building the directory may not be a big deal because all certificates for a company can be published in a central lightweight directory access protocol server,but externally this causes many problems.you will need to establish an agreement with a recipient's organization to ensure access to the right digital certificates.this process, however, creates more user training issues and adds complexity to e-mail communications.

最困难的问题是建立数字证书目录。此目录保存着向一名接收人发的信息进行加密所需的证书。从内部讲，建目录可能不是件大事，因为一家公司的所有证书可以由中央简化目录访问协议服务器颁发，但从外部讲，这会引起很多问题。你需要与收件人所在组织达成协议，以确保访问正确的数字证书。然而，这个过程会造成更多的用户培训问题以及增加电子邮件通信的复杂性。

Jewish Immigrant Problem was the result of the political,economic and historical development in the USSR; Soviet government's restrictive policies to Jewish immigration led to the emergence of a new,special political gr oup-the Refuseniks, which set the aim of their activities at emigrating abroad ; the emigrating will and the activities of the Refuseniks attracted the attention of the West,especially Americans,and became an important factor influencing the economic and trade relations between the USA ...

苏联犹太移民问题是苏联历史和政治、经济发展的产物。由于受多种因素的影响，苏联对犹太移民的意愿采取限制性的政策，由此产生了苏联政治生活中移民申请被拒绝者这一特殊的政治群体，他们以移居苏联国外为其主要的政治目标。苏联犹太人的移民意愿及移民申请被拒绝者的活动引起西方社会尤其是美国的关注，并在一段时期内成为影响美苏经济贸易关系的一项重要因素。戈尔巴乔夫实行的改革开放政策在一定程度上缓解了这一问题，此后苏联的解体使这一问题的性质和重要性均有所转变。

A large number of algorithms have been proposed in the literature, which differ from each other based on the type of institution involved and the type of constraints. This paper first surveys the origin and the techniques, then presents the AI Planning-based algorithm to solve TTP. We implement the algorithm by SQL language, which is Timetabling Problem, and show that it is of great value by using the simulated data on it. At the end of this paper we describe other applied domains and its prospect.

时间表问题是一类应用非常广泛的研究课题，目前业出现了各种各样的解决时间表问题的方法，本文简要分析了近几十年时间表问题研究的历史和技术现状，提出了基于智能规划方法的时间表问题解决方案Plan TTP，并且我们用SQL语言实现了这一解决方案Plan TTP，通过对学校课程表的模拟实验证明该方法具有较大的使用价值，最后指出Plan TTPS的一些其他应用领域和发展前景等。
