1 . temperature measurement surface thermocouple with protective tube directly welded on the surface of furnace pipe to avoid scouring from extremely flow velocity and damage to measuring element at high temperature , also corrosion to the thermocouple from hydrogen and sulfur 1 .一种带护套管测温表面热电偶，护套管直接焊在炉管表面，避开了高流量冲刷，高温温度对测温元件的破坏，氢硫对热电偶的腐蚀
This is portable pump with strong suction and medium head doss , equiped with extraordinary hair collector ; the body is made of themal plastic of strength ening fiberglass with good corrosive and impact resistance ; and with the advan tages of high flow , quiet 这是一款轻便、自吸式、中等扬程的水泵、配有特大的毛发收集器；泵体由玻纤增强的工程塑料注塑而成；有良好的抗冲性和耐腐蚀性；此水泵具有高流量、运行安静之优点。
Especially in high traffic web sites , it is important that clients use database connections from a pool of database connections managed by an application server for example , ibm websphere application server and that they release the database connection after their necessary transactions have occurred 尤其是在高流量的web站点中，客户机应该使用由应用程序服务器（例如， ibm websphere application server ）管理的数据库连接池中的数据库连接，并在其必要的事务发生之后释放数据库连接，这一点很重要。
Paniculate organic carbon ( poc ) content of zhujiang river is lower than that of other rivers in the world . among the three branches , the content in xijiang river is the highest , then the dongjiang river , and then the beijiang river . the runoff of zhujiang river has very great seasonal change 珠江流量存在很大的季节变化，汛期拥有超过60的年度总径流量， doc和poc在高流量时骤增， doc含量增加约20 - 90 ，而poc含量最大则可能增加6倍，与山区河流的特征相似。
