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。

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。
