The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。

The electric price of infrared ray equipments is high, making the high cost for the products and low efficiency of drying; The price of boiler and its auxiliaries for the radiating fin drying is high, its repairing fee is large and utilization ratio of fuel is low; Although the drying efficiency of hot wind boiler is high, it has large volume of the equipments and high price and is not suitable for the most enterprises.

采用红外线干燥装置由于电价高，企业生产成本较高，干燥效率低；散热片干燥方式采用的锅炉及其配套设备价格高，维修费用大，燃料利用率低；热风炉虽然干燥效率高，但设备体积大，价格昂贵，大多中小企业不愿使用。

In nano/micro fluidic systems, the surface to volume ratio becomes too large to neglect the electrokinetics on the surface.

在奈米/微米流体系统中，表面对体积比远较一般系统大，因此必须考虑表面的电学效应。

The basic methods are volume displacement , addition of kinetic energy, and use of electromagnetic force.

根据它们给流体传输能量的方式来将它们分类，基本的方式是体积位移、增加动能和使用电磁力。
