If only on the K line combinations to judge the short-term direction of the operation, will inevitably face more uncertainty risks, but also tried to Rs easily formed the habit of a strong rise in the often away prematurely in the hands of profit-chips, in the mining market rebound due to the strong efforts to weak difficult to grasp , it is easy bearing.

In the presently mobile position technology, GPS's position method is one of the best. This method owns high accuracy less than 15 meters, and can be used with GPS chip in the mobile station. But GPS chip with the high price makes this technology difficult to popular. Therefore, the position technology of GSM communication network is attention to the people gradually. TOA or AOA is more often used among position technology, these methods need only the help of the position measuring instrument to attain time and angle for position calculation. They have good position accuracy, but they are also too expensive to popular. Every positioning technology has its bottleneck such as external environment influence, cost and positing efficiency. Therefore, the purpose of this research lies in finding out the mobile station location and does not emphasize the raise of the accuracy and it only uses existing information to finish position action.

在目前的行动定位技术中，以GPS定位技术为最佳，不仅拥有少於15公尺的高定位精确度，更只需在行动端加装GPS晶片即可使用，可惜高价格的GPS晶片使得此技术难以普及化，因此，以GSM通讯网路为主的定位技术逐渐受人们所重视，其中，又以TOA或AOA等定位技术较常被使用，仅透过位置测量仪器的帮助，便可取得定位所需的时间和角度，并且拥有不错的定位精确度，可惜也受到高价格因素的关系难以普及化，而每种定位技术都有其瓶颈存在，不论是外在环境的影响、成本和定位效能上；所以，本研究的目的在於找出行动端位置，即利用现有的资讯（细胞识别码、讯号强度等）来完成定位动作，而非强调其定位精确度的提高。

In fulfilling the provisions in the Charter, youth groups have found it most difficult to help young people form a proper sense of social values, to prepare them for future changes in society, to help develop their talents, to encourage participation in social development, to protect them from undesirable influence and to assist families in taking up the role of a care-giver.

Structured system employs a scalable scheme to guarantee search success, but it needs to maintain strictly controlled overly network, it is difficult to adapt to highly dynamic network environment of P2P. In addition, the use of DHTs leads to the fact that only keyword exact-match is available.

结构化系统使用可扩展的方法能保证查找的成功，但由于要维持严格控制的叠加拓扑，因此对P2P网络中大量节点的动态变化适应性较差，且由于分布式哈希表的使用使其只支持精确查找。

At present, land prices of gold accounted for 20%~ 30%, this part of the decline in the amount of housing prices, will impact the market to bid up housing prices fall, real estate prices are adjusted according to demand, the final price or return to the original location, The owners bought the house in future would also like to pay property tax each year, resulting in dark or drop out, so he personally thought that this method more difficult to implement, the only advantage of government departments have a long-term stability of the land transfer income, the current land fewer and fewer resources, long-term gains must be better than a one-time income, and land-use period are generally more than 50 years, so turnover is very long, long-term cycle of charges on the comparative advantage of government departments.

目前，土地价格的黄金占20 ％ 30 ％，这部分减少的数额，即住房价格，将影响市场抬高房价下跌，房地产价格是按照需求，最终价格还是回到原来的位置，业主买的房子今后还要财产税，每年造成黑暗或辍学，所以他个人认为，这种方法更加难以实施，只有利用政府部门一个长期稳定的土地转让收入，目前土地资源越来越少，长期收益，必须优于一次性收入，土地使用期限一般都超过50年，因此，营业额是很长的长期周期费用的比较优势的政府部门。

With the financial supervision departments to strengthen supervision of commercial banks and commercial banks to the deepening of its reform, China's commercial banks to gradually improve the internal control, or commercial banks, however some problems, such as the internal control system it is difficult to adapt to business development; Weak internal audit; Perfect risk control system; Loans "Richard III" in the implementation of the system to be further strengthened and so on.

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.

如果一个数据库一致的合理观念要得到支持（即数据库系统要自动实行这个观念）、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待，就必须提供某种协商解决矛盾的方法，从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当，在这个环境中，要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的，同时用户们又紧密地合作在一起。

Therefore, despite early November 1941, the Kremlin has been in sight in the distance, the Soviet government and foreign embassies have been moved to Moscow 800 km east of the kuibyshev, but on November 7 As in previous years, Stalin still in Red Square October Revolution Day military parade conducted by the troops available (including from the Far East and Siberian Military District to transfer the force) has just been reviewed to receive input on the battlefield, to December 5, 1941 the Germans were to stop the offensive, they have the logistical supply line To the limit, along with fronts in the rear of the guerrillas continue to undermine the Soviet Union, has been difficult to attack the front-line troops, following the Victoria - the German "invincible" crush on this myth.
