The effects of the buffer solution in treatments after dyeing and printing;

Teaching and analysis of calculating pH Value of buffer solution;

In order to theoretically elucidate the mechanism of absorption and desorption of sulfur dioxide by citrate solution and provide theoretical instruction for experiments and industrial application, the influence of initial pH, distribution coefficient, buffer index and buffer capacity on the properties of the buffer solution were studied in this work.

The paper has discussed the effect to well water quantity using flushing fluid and different kinds of well drilling,it has studied the advanced and shortcoming of chemical fluid and piston washing well.

And the calculation methods of sinking coefficient,minimum flow of flushing fluid and minimum sinking depth,which affect hole cleaning effect,are put forward to guide construction effectively.

The infection of the washing liquid used in the pump at the decompression tower bottom to the medium was introduced.

A 1-D mathematical model,including the electrical potential distribution equation,the buffer concentration equation,as well as the sample electromigration and diffusion equation,is developed through proper simplifications and assumptions to study the sample stacking process in capillary electrophoresis.

Sample stacking in capillary electrophoresis can concentrate sample species through the electrical field strength gradient caused by the inhomogeneous buffer concentration field in capillary.

A 1-D mathematical model including electrical potential distribution equation,buffer concentration equation,as well as sample electromigration and diffusion equation was developed through proper simplification and assumption to study sample stacking process in microfluidic chips.
