It Discusses the relationship using steam or electricity for power after the coal boiler being put into operation, and provides some idea for choosing drivemode during production.

Here the author analyses the design theory that adopts a way of steam dirict heating and damping,anduses the theory to design high temperature and high humidity in budding room .

In order to meet the demand of the energy conservation and the balance of steam system,a scheme of steam ejector system is presented.

Although the technique of chemical vapor generation has been developed forover l00 years, it sill plays an important role in modern analytical atomicspectrometry until today The technique has become popular fOr thedetermination of trace elements in the complex matrices and new aPproachescontinuously comes forth to improve the sensitivity and expand the scope ofaPplications.
