For the aim of saving energy and optimizing control of chilled systems, the performance of VWV systems and characteristics of control systems were analyzed based on the simulation. According to the characteristic of the monitored parameters and controlled variables in VWV systems, three online optimal control strategies were proposed and validated:(1) Optimal strategy for on/off control of chillers according to the ratio of secondary flow rate to primary flow rate.(2) Optimal strategy for the control of secondary pump according to value positions of auto-controlled AHU vales. And (3) Optimal strategy for supply chilled water temperature control of chillers according to valve positions of auto-controlled AHU valves and working status of secondary pump.

为达到节能和优化系统控制的目的，在楼宇空调水系统及其局部控制仿真分析的基础上，针对变流量系统监测点和可调参数较多的特点，提出并验证了3个实时优化控制方案：根据初级和二级冷谋水流量的比率，实时优化多台冷水机组的启／停控制；利用AHU自动控制水阀的阀位信息，实时优化二级水泵的控制；利用AHU自动控制水阀的阀位信息以及二级泵的工作状况，实时优化冷水机组出水温度的控制。

Caffeine - A derivative of coffee, is an efficient arouser of central nervous system capable to drive away fatigue, and improve renal circulation. Its stimulation on the cerebral cortex activates Neurotransmitter receptors in the cell membrane; the adenylyl cyclaseactivated on the other surface of the cell catalyzes Adenosine Triphosphate, forming Cyclic adenosine monophosphate, and thus set off series of bio-chemical reactions, like increase of passionate feel, prompt recovery from fatigue after working etc..

咖啡因—由于咖啡本身具有兴奋神经中枢，消除疲劳，增加肾脏血流量的作用，通过对大脑皮层的刺激，使神经递质作用于细胞膜受体，激活了膜另一侧的腺苷酸环化酶，被激活的腺苷酸环化酶催化三磷酸腺苷环化酶，被激活的腺苷酸环化酶催化三磷酸腺苷形成环磷酸腺苷，从而引起一系列生化反应，如增加愉快感和消除事后疲劳等。

在沙滩时我们都不约而同的脱下鞋子光着脚奔向海边，距离海水远的沙子踩上去又软又涩，在那儿偶尔还会被坚石和碎贝扎到脚，走过这段"深一脚浅一脚"的海滩，来到海边，离海水近的沙滩和刚才的沙滩又是有着天壤之别，由于长期受海水冲刷，所以平坦得像一张巨大的画水墨画的宣纸，看上去既想在上面踩几脚感受一下它的平滑，又怕把自己的脚印印在上面，破坏了这天造地设的"画卷"。

They divided it into cakes by methods too well known to require description, and these, being sledded to the shore, were rapidly hauled off on to an ice platform, and raised by grappling irons and block and tackle,worked by horses, on to a stack, as surely as so many barrels of flour, and there placed evenly side by side, and row upon row, as if they formed the solid base of an obelisk designed to pierce the clouds.

他们把冰切成一方块一方块，那方法是大家都知道的，无须描写的了，这些冰块放在雪车上，车到了岸边，迅疾地拖到一个冰站上，那里再用马匹拖的铁手、滑车、索具搬到一个台上，就像一桶一桶面粉一样，一块一块排列着，又一排一排地叠起来，好像他们要叠一个耸入云霄的方塔的基础一样。
