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.

Electron micrograph showed us that hepatocytes were damaged seriously along with the prolonged NHBD time in A group. At the NHBD 120 and 150min in A group, hepatocytes showed numerous cytoplasmic vacuoles and lysosomes, round swollen mitochondria with clear matrix and rough endoplasmic reticula which was not in a stacked arrangement.

电镜发现，A组随着心跳停搏时间的延长，肝细胞的损伤逐渐加重，至120和150min时，肝细胞内可出现大量空泡和溶酶体，线粒体和粗面内质网结构也遭到破坏，但未出现明显的坏死和凋亡改变。

It is determined as a result of heating facilities, regular and high-temperature heating. It operated hot water pipes so that in the 15 ℃---- 90 ℃ from time to time between the operation, resulting in accelerated aging boiler and pipe rust and scale in the United States on heating and heating from time to time out after a period of time. The purpose is to accelerate the pipeline of the scale and rust solid precipitation knot a few years later so easy to plug.
