Apparently the prosperity of Q4 also can be inspected is the Yu Hui that game of a kind of network takes bottleneck period, after all nowadays is not the times that relies on single product to make the world any more, if walk out of,allow " demon animal world " odd group, avoid single product to promote a company, single product dies an awkward condition that the company dies, it is each net swims actually the issue that the company must consider, and this one problem is generally even to swim with the net of those a gleam of in old man, diversity or the key that will become broken undeceive bureau, and if realize diversity truly, will be all game company the decisive issue that 2009 place must consider.
表面上Q4的繁荣也可以视作是一种网络游戏走入瓶颈时代的余晖,毕竟如今已经不是靠单个产品打天下的时代,如果走出准《魔兽世界》的怪圈,避免单个产品兴则公司兴,单个产品亡则公司亡的尴尬境地,其实是每一个网游公司都必须考虑的问题,而这一问题甚至普遍存在与那些一线的网游大佬之中,多元化或将成为破解迷局的关键,而如果真正实现多元化,将是所有游戏公司在2009年所必须考虑的关键性问题。

For single-attribute range queries in Armada, this thesis designs the single-attribute order-preserving naming algorithm Single_hash to assign adjoining ObjectIDs to objects with close attribute values based on the partition tree model, so that the objects can be published to the same or related peers in the P2P system. Then this thesis proposes the single-attribute range query processing algorithm PIRA, which can match the search paths of range queries to the underlying FissionE topology efficiently based on the forward routing tree to reduce the delay and message cost of range queries.
为实现Armada单属性区间搜索,本文首先提出基于分区树的单属性维序命名算法Single_hash,使得属性值接近的资源对象能够获得相近的标识,以发布到相同或相关的结点上;然后提出基于前向路由树的单属性区间搜索算法PIRA,实现了区间搜索路径与底层FissionE拓扑的高效匹配,以有效降低区间搜索延迟,减少搜索消息开销。

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.
本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究,所开展的主要工作和研究结果如下: 1、对过电压的产生机理及其影响因素进行了分析,指出单相重燃是导致开关设备损坏的主要原因,而两相重燃则是导致电容器组损坏的主要原因,因此单相重燃和两相重燃过电压是防护的重点; 2、对电容器组操作开关的特殊运行条件进行了分析,指出在这种运行条件真空开关难于实现不重燃,因此采用保护装置更具有现实意义; 3、对RC与MOA的保护效果和存在的不足进行了分析,指出这两种方法均只能有效抑制单相重燃过电压,而不能在发生两相重燃时保护电容器组; 4、重点对G-R阻尼装置的工作原理进行了分析和讨论,指出该装置接入后线路中将会出现两种频率的高频振荡,而电容器组上的过电压是由这两种振荡共同决定的; 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低,并提出了电容器组电压和最佳电阻值的近似求解方法; 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算,证实该装置确实可以有效抑制重燃时的电容器组过电压; 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法,经过修正后的过电压计算结果与仿真结果吻合较好; 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析,指出采用编织电阻和真空间隙可能是最佳选择。
