空气

The energy saving principle of total heat exchanger is that it use discharge air to precool or preheat fresh air which can reduce the load of fresh air and save energy.

全热交换器的节能原理在于，它可以用排出的室内空气来预处理新风，使新风的负荷降低，从而节约空气处理设备的能源消耗。

Fan air is used as cooling air for the precooler to limit the temperature of the bleed air in the pneumatic manifold.

风扇空气做为预冷器中的冷却空气用以限制增压总管中的引气温度。

In one embodiment, moist air (180) entering the system flows first through a precooler (air-to-air heat exchanger)(100) and then passes across an evaporator (110) that cools the air below the dew point and producers water.

在一个体现，潮湿空气（ 180 ）进入系统的流量首先通过precooler（ 100 ），然后通过横跨一蒸发器（ 110 ）表示，冷却空气低于露点和生产者的水。

From 2003, air auto-monitoring system s in provincially administered municipalities were inspected by Henan environmental moniroing station,and influencing factors in air auto-monitoring system operation were found in several years inspection.

为了掌握省辖市2003年以来空气自动监测系统的运行情况，根据几年的巡检，发现了一些影响空气自动监测系统运行的因素。

Focus: Application of psychrometric chart of humid air, basic processed of humid air and its application

重 点 ：湿空气焓湿图的应用，湿空气的基本过程及其应用。

Because of the complex nonlinear relationship among psychrometric properties ,using conventional approaches to measure psychrometric properties is very difficult for hardware implementation,and can not satisfy the need of air-conditioning real-time control also.

为了解决这一问题，本文根据空调设计过程的特点，利用人工神经网络方法，建立了两个湿空气状态参数的神经网络预测模型，实现了湿空气状态参数的智能化预测。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
