查询词典 passive

And has brilliant prospect due to its simple structure, good economy and energy saving performance.Based on the full scale passive solar experimental building in DUT, in which the researcher carried experiment as the main method and the CFD simulation as the minor method, the research focuses on passive ventilation formed by the Trombe wall. This paper analyzed the indoor thermo and humidity performance of passive solar building with Trombe wall, and the different ventilation patterns in different seasons, revealing the role of passive ventilation in improving indoor environment. Also the paper researched the characteristics of passive ventilation on air flow and heat transfer mechanicsms, and put forward the best control and adjusting method. Meanwhile the paper gained an empiric formula in use of calculating the natural convection heat transfer and found the key factor of influing the indoor environment.

本研究以被动式采暖降温技术为依托，采用实验和CFD数值模拟的研究方法，重点研究了新型被动式太阳房在不同气候条件下室内热湿环境的动态变化规律，分析不同季节下被动式太阳房内不同的被动式通风模式以及不同被动式通风模式在改进室内热湿环境方面的作用：揭示了特定被动式通风流动和换热特性、控制与预测方法；得到了计算被动式通风对流换热量的经验公式以及影响室内热湿环境的关键因素；了解了含有特朗贝墙体被动式太阳房的自身优势和仍待改进的方面；在实体大被动式太阳房实验技术方面积累了一定的经验。

R·Quirk and other experts divide passive voice into three types : true passive , quasi-passive and pseudo-passive .

一导言英语中的语态是一个语法范畴，是表示主语和动词之间关系的动词形式。

Zhang Keli and some other grammarians divide the passive voice into three kinds: true-passive, pseudo-passive and quasi-passive.

张克礼等一些语法学家认为被动语态可以分为三种：真被动，假被动和半被动。

There are two types of passive voice used in English: passive structure and quasi passive structure.

英语中的被动式有两种类型，即被动式和类被动式。

The English passive voice can be divided into the actional passive and the stative passive.

摘要英语被动语态可以分为行为被动语态和状态被动语态。

Some prepositions, not only can collocate with the actional passive, but also with the stative passive. Some prepositions can only collocate with the stative passive.

有的介词既可以与行为被动语态搭配使用，也可以与状态被动语态搭配使用；有的介词却只能与状态被动语态搭配使用。

On the other hand, from the point of view of work manner, thedetecting systems can be classified two kinds: the active and the passive systems. Althoughthe passive detecting system can\'t get so much information as the active one, it has itsspecial characteristic. For instance, the passive system is immune to the radar clutter. It issecreting and has no electromagnetic pollution due to none of radialization. The passivesystem also has excellent capability of detecting the target covered with the stealth material.

从工作方式来看，探测系统还可分为主动和被动两种方式，虽然主动工作方式可以获得关于目标的更多信息，但是被动工作方式也有其不可替代的特性，如不受闪烁效应的影响；由于本身不发射电磁波，因而没有电磁污染及工作比较隐密；对覆盖吸波材料的目标探测能力很强等。

As for the translation of passive voice in EST, the passive structure can remain unchanged. Passive sentences in English are translated into active voice in Chinese by changing original objects or subjects, adding subjects, and being converted into subjectless sentences or other structures for a good translation.

对于科技英语中被动语态的翻译，被动结构可以在汉语中保持不变，但大部分被动句的翻译是通过转换原句主语和宾语或者是增添主语，转化为汉语的主动语态，也可以是转化无主句和其它结构，从而使译文更通畅。

Aiming at the problem of indoor air temperature being too high in summer, carries out an experiment in passive solar house with an advanced Trombe wall in marine climate region. Explores the cooling effect and indoor air temperature in different passive cooling modes. Obtains the optimal operation mode and ventilation pattern for passive cooling.

针对被动式太阳房普遍存在的夏季室内过热问题，对海洋性气候条件下带有新型特隆布墙的被动式太阳房进行了实验研究，分析了不同被动降温模式的降温效果和室内空气温度分布，给出了适用于该类太阳房被动降温的最佳通风模式，认为内壁面温度是室内气温最显著的影响因素。

With low donor and acceptor density and anion adsorption on surface of passive film, effectively preventing the adsorption of Cl(superscript -) in passive film, the resistance to localize corrosion of passive film was greatly improved.

低的施主与受主浓度及钝化膜表面负电荷的增强，可有效排斥侵蚀性Cl在钝化膜表面的特性吸附，有利于提高不锈钢的耐局部腐蚀性能。
