The parameters optimization design model is proposed, which is based on a control model with the quasi-Euler angle, Euler angle velocity and absolute angular velocity as the feedback. The vibration-resistance parameters of the given controller are chosen as the optimization variables, and the on-off times of the engines is chosen as the optimization objective function.

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.

Suffer visit a passenger I had stayed in Beijing half an year, ever since basic and annual can go, to Beijing's public transportation impression, manage a disorder namely, be being returned basically is not ticket of unmanned carry out (likelihood and solve population of Beijing obtain employment to concern, otherwise cannot understand), the client thinks from which on the door, it which door falls is OK that which door falls, this was the bus order that have to cause completely to original person very shambolic, booking clerk is staring at every person that get off like preventing a thief, this kind of taste is extremely bad to suffer, every person that gets on a car should tear a bill, show monthly ticket of what those who caused work efficiency is low, what also created mood of booking clerk job is fretted of the objective reason that reckons this also is this second tragedy.

受访乘客我在北京呆过半年，其后基本每年都会去，对北京公交的印象，就是治理混乱，基本还不是无人售票(可能与解决北京就业人口有关，要不无法理解)，顾客想从哪个门上、哪个门下都可以，这给本来人满为患的公交车秩序造成了很大混乱，售票员像防贼一样盯着每个下车的人，这种滋味极不好受，每个上车的人要撕票、出示月票什么的造成了工作效率的低下，也造成了售票员工作情绪的焦躁(估计这也是本次悲剧的客观原因之一)。
