The use of gas exhaust in local mine 瓦斯抽放在地方及乡镇煤矿的应用
Cause analysis and solution of the abnormal gas exhaust from diesel engine 柴油机排气异常的故障分析及排除
Research on treating tail gases exhausted from diesel engine by pulse corona plasma 脉冲电晕放电等离子体净化柴油机尾气的应用研究
The reason of misrun and cold - lap formation in thin - walled aluminum casting is analyzed . increasing gas exhaust capacity in mould and filling velocity and controlling melt temperature are favorable methods for better effect 对薄壁铸铝件浇不足及冷隔的形成原因进行了分析,提出了增大铸型排气性、提高充型速度、控制出炉温度的解决措施,效果良好。
As the sealing technique and gas exhausting technique were carried out in the later manufacture stage , the technique result would relate to good finished ratio of fed , which is very important for the whole fed manufacture 由于封接及除气工艺在fed制造过程中属于后道工艺,它的成败直接影响到fed显示屏成品率高低,因而对整个fed显示屏的制造具有举足轻重的意义。
We can go through the engine performance test , timing character test , gas exhaust test and durability test , which can be mainly used in exhaust performance test for non - road mini - engine , catalyst performance test and durability test 可进行发动机性能试验调速特性试验尾气排放试验,强化耐久试验等,主要用于非道路小型发动机排放控制性能试验及催化剂性能及耐久试验。
It is widely acknowledged that the automobile exhaust contributed to environment pollution . experts argue that the goverment must confine the quantity of off - gas exhaust . but i doubt whether quantitiy confined alone will solve the problem 众所周知过度地砍伐森林会导致夏季洪水泛滥,专家建议中国必须推行大规模的植树造林计划,但是我对单靠植树造林就能解决问题持怀疑态度。
We can go through the engine performance test , timing character test , gas exhaust test and durability test , which can be mainly used in exhaust performance test for non - road mini - engine , catalyst performance test and durability test 可进行发动机性能试验、调速特性试验、尾气排放试验,强化耐久试验等,主要用于非道路小型发动机排放控制性能试验及催化剂性能及耐久试验。
In this paper , the structure of fed , operation principle of fed and the manufacturing process were presented at first . emphasis of this paper was put on the investigation in low melting - point glass sealing technique and gas exhausting technique 本文首先对fed平板显示器的结构、工作原理、制造工艺过程进行论述,重点论述了对fed平板显示器件的低熔点玻璃封接及除气工艺的研究。
When underground water is used , there is no need to equip boiler , so there is neither cold or hot wind nor waste gas exhausted into the air and the heat - island domino offect of being hotter in summer and colder in winter in the city will not happen 当采用地下水时,不用锅炉,没有冷热风排到空气中,不会产生废气,不会造成城市夏天更热,冬天更冷的热岛效应,如果采用新冷媒,不会对臭氧层造成破坏,保护人类生存环境。
