Two kinds of glassfiber reinforced composites developed by ASIPP were tested at room temperature for evaluating their vacuum performance.
将EAST装置所用的绝缘子玻璃钢材料和超导磁体绝缘结构所采用的玻璃钢材料放入自行设计的真空性能评价装置的样品室,在常温下进行出气率试验。
The theoretical analysis was conducted systematically for the altitude performance of the oil pump from fluid dynamics.
从流体力学角度,对滑油泵的高空性进行了系统的理论分析:阐述了其产生原理,推导了各种影响因素之间的关系式,得出了如下结论:泵前总阻力系数、滑油密度、油泵设计流量越小,入口管径越大,越有利于保持泵的高空性;而对于转子泵,内齿轮1齿扫过的面积越小,内齿轮齿数越少,内齿轮转速越低,转子宽度越小,越有利于保持高空性;对于齿轮泵,模数和齿数越少,转速越低,转子宽度越小,越有利于保持高空性。
As construction is with the sociality & homologusy of culture, openy of organize systemic and overtimey, it is the powcrliest fact proof of expatiatal collectivity diagnosis in the are history.
建筑本身所具有的社会性与文化的同构对应性、组织系统的开放性、超时空性使它成为文化史中阐述时代总体特征的最有力的实证。
The space-time performance of this method was superior to discernibility matrix′s.
研究表明,依赖度法的时空性能比分辨矩阵法更加优越。
The paper proposes an improvement for SCC-based emptiness checking algorithms,which combines the advantages of SCC-based and nested depth first search for finding a cycle meeting all sets of acceptance conditions.
对Couvreur提出的基于强连通图的空性检测算法进行改进,使基于嵌套的深度优先搜索与基于强连通图搜索算法的优势结合起来,在对基于迁移的扩展(具有多个可接受条件)Büchi自动机进行空性检测过程中,使用一个布尔变量标识一个状态,不仅节省了内存消耗,而且一般情况下的性能明显优于已有的算法,最坏情况等同于Couvreur的算法。
