分布式燃气冷热电联供系统（DES/CCHP）是一种建立在能量梯 级利用概念基础上，以天然气为一次能源，同时产生电能和可用热 （冷）能的分布式供能系统。 作为能源集成系统（Integrated Energy Systems），冷热电联供 系统按照功能可分成三个子系统：动力系统（发电）、供热系统（供 暖、热水、通风等）和制冷系统（制冷、除湿等）

6.1 The Magnitude-Phase Representation （ 幅度-相位） of the Fourier Transform

In motorships the oil, after passing through main and motion bearings and oil-cooled pistons, etc., is either retained in the bedplate or flows by gravity to a sump tank. In either case, the oil pumps, which may be self￾priming, submerged centrifugal or rotary positive displacement, draw the oil through magnetic strainers and discharge to: filters - oil coolers - engine lubricating and/or cooling manifolds

Open systems using gravity tanks, etc., are rarely met nowadays and Figure 1.8 shows a characteristic arrangement of pressure tanks, calorifiers and pumps for a large ship. The fresh water pumps are self-priming, drawing from storage tanks and discharging through filters to a rising main, branched to give a cold supply and a hot supply in closed circuit through a calorifier. A tank kept under pressure by an external supply of compressed air rests on the system and provides the head necessary

In motorships there are two main circuits, one salt , one fresh. The salt circuit is: sea inlet box (seachest) - pump(s) - f.w. coolers in series (first LT then HT) – turbo blower aftercoolers in parallel (if any) – provision condenser in parallel (if any) - overboard

5.1 Introduction In this chapter, copper is considered as a case study for the measurement of the effect of nutrient intake. The importance of the role of copper in biological systems is first explored in a brief review of selected human cuproenzymes
