Currently in a surface warship of the our country everyplace all provided with the sail coal gas body to report to the police the instrument on the boat, gas density that sensor adopt to convey gas density value traditional 4-20mA mode of analog signal, have to each measure passway allocate one is it is it report to the police to measure to have and density value show measuring board of function, as the density of gas measures the passway board of the different quantities of different outfit of the figure of the passway, but there is many figure of the large-scale naval vessel passway, so the volume of warning system will become very huge , unfavorable to attenbants to use, and traditional 4-20mA electric current ring transmits the signal, unfavorable to transmitting at a long distance, easy to bring and interfere.

核心提示：摘要目前在我国各地型水面舰船上都配备了航煤气体报警仪，气体浓度传感器采用的是传统的4-20mA模拟信号的模式传送气体浓度值，只好每个检测通道配备一块具有检测报警及浓度值显示功能的检测板，随着气体浓度检测通道数目的不同配备不同数量的通道板，但大型舰船通道的数目比较多，因此报警系统体积会变得十分庞大，不利于操作人员使用，而且传统的4-20mA电流环传输信号，不利于长距离传输，容易带来干扰。为了巡检的需要，需要将其改造成现场智能仪表，通过将传感器检测结果

Recently, acute poisoning frequently happens which is caused by the release of chlorine in the production process,as the dense gas,chlorine dispersion model contain continuous diffusion and instantaneous dispersion, and we can separately use dense gas flat plume model and dense gas box puff model to calculate the density of the gas.

risk analysis ； dispersion ；近来，生产过程中氯气泄漏引起的急性中毒事故频繁发生，作为重气的氯气泄漏扩散分为连续扩散和瞬间扩散二种模式，并且分别应用重气云羽平板模型和重气云团盒子模型来计算重气扩散浓度。

By collecting previous research results of water-drive gas reservoirs and analyzing their macro and micro mechanisms of water encroachment,different development measures are designed respectively for their three development periods of water-free gas recovery,gas flowing with water and water-discharge gas recovery.

摘要通过收集前人水驱气藏开发的研究成果，对水驱气藏储层宏观和微观水侵机理进行分析，总结出了无水采气、带水自喷和排水采气三个阶段水驱气藏的不同开采措施。

A year ago, wrangling over the price of gas sold by Russia to Ukraine briefly diminished the flow of gas through Ukraine to Europe. At the end of 2006, Belarusian resistance to Russia's demand that it too pay more for gas threatened to unleash another so-called "gas war".

一年前，围绕俄罗斯销往乌克兰的天然气价格之争使得途经乌克兰输送至欧洲的天然气量锐减。2006年底，俄罗斯提出要对销往白俄罗斯的天然气进行涨价，白俄罗斯人对此进行了抵制，新一轮所谓的&天然气之战&一触即发。

Russia and Ukraine have been disputing more intensify in gas prices and gas transit issues for many years. The natural gas dispute between the two countries has become regular program after the"Orange Revolution". At the beginning of this New Year, a"gas war"once again cast a shadow on relations between Russia and Ukraine. But an agreement ultimately has been reached between the two countries through many times coordination by the European Union, that means the end of the struggle.

多年来，俄罗斯和乌克兰两国在天然气价格和天然气过境问题上的争执愈演愈烈，两国之间的天然气纠纷几乎成了&橙色革命&之后的定时节目。2009年初的一场&天然气大战&再次给俄乌关系蒙上阴影，但在欧盟多次协调下两国最终以达成协议方式而结束了争斗。

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。
