Usually, distribution networks operate in arborescence mode, so in the simulation of fault analysis the impact of faulty switch element on system reliability is apportioned to failure consequences of adjacent sections that connect to switch, and then an equivalent analytical model considering switch fault is proposed. Thus, not having to conduct the reliability analysis of switch element singly, the impact of switch element fault on system reliability can be calculated. Applying the proposed algorithm in RBTS-BDS6 system, RBTS-BUS4 system and actual medium-voltage distribution network to conduct reliability assessment, the results show that the proposed algorithm is superior in speed and possesses efficiency and engineering practicality.

配电网常具有树状运行特点，在故障解析模拟时，将开关元件故障对系统可靠性的影响分摊到连接开关的相邻分块的故障后果中，进而提出计及开关故障的可靠性等值解析模型，不需单独进行开关元件故障的可靠性分析即可计算其对系统可靠性的影响，应用该算法对RBTS-BUS6和RBTS-BUS4系统及实际中压配电网进行了可靠性评估，结果表明该算法有较明显的速度优势，具有高效性和工程实用性。

The primary phases of Al-10% Cu, Al-20% Cu Al-40% Cu alloy are nearly equiaxed spherical or rose spherical by semi-solid processing. Compared with the coarse arborization of Al-10% Cu, Al-20% Cu Al-40% Cu alloy of conventional casting, the structure of alloy is extremely improved and the appropriate grain size for the engineering application is obtained.

结果表明：利用半固态加工，可以使Al-10%Cu、Al-20%Cu、Al-40% Cu合金的初生相呈近等轴的球状或蔷薇球状，与普通铸造Al-10% Cu、Al-20% Cu、Al-40%Cu合金较粗大的树枝状相比，合金的组织得到显著的改善，达到了工程应用晶粒大小。

So it is very important that the interaction of urban new region and public transportation. The strategies contain planning of urban new region and transportation, developing of new region and building of transportation infrastructure, and policies of land use and transportation. The key measures include collocating for land source, alloting for road right of way, traffic engineering, transportation demand management, new transit mode, planning of settlements and site, architectural design, etc.

文章指出了新区开发面临两大压力，即土地资源日益紧张甚至枯竭的压力和小汽车爆发式增长带来的道路交通拥堵的压力；提出了从新区规划、建设和政策三个层面建立新区开发与公交优先互动机制，并指出了其内涵和外延；重点从资源配置、路权区分、交通工程、需求管理、公交新模式、居住区规划、建筑设计等方面提出了新区公交优先发展若干关键举措。
