Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents).

现在的泵系统通常是一元或多元计算机控制的计量泵组成，它们可以通过编程来改变流动相的组成，以满足梯度色谱的要求或者用来混合等度流动相（也就是流动相的组分可以有一个固定的溶剂配比）。

According to the problem of outlet leakage of propane on the propane pump mechanical seal in the olefine factory of Qilu petro-chemical company, the new-type assembling non-contacting mechanical seal for propane pump was developed firstly on the basis of the principle of non-contacting of mechanical seal .

针对齐鲁石化公司烯烃厂丙烷泵机械密封频繁出现汽喷现象、密封端面泄漏严重的问题，根据非接触式机械密封原理，研制开发出了丙烷泵用新型非接触式机械密封。

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。

We can see that the low energy states absorption of Ho〓, Er〓, Tm〓 in oxyfluoride glass-ceramics sample is strong. Strong absorption makes for high pump efficiency, and easy to sensitization. Further more, strong absorption in wide frequency range will be avail to the choice of pump sources.

研究发现Er〓、Tm〓与Ho〓离子在氟氧化物玻璃陶瓷中各低能激发能级均有较强的吸收，相应的吸收跃迁振子强度有较大值，因此可选择的泵浦波长较多，同时，强的吸收将产生高的泵浦效率，且利于敏化。
