Introduction Furfural is a kind of important organic chemical raw materials and chemical solvents, widely used in petroleum refining , petrochemical , pharmaceutical and synthetic rubber industries[1], moreover, So far only by plant fiber source and exhaustion of fossil energy, the demand of furfural will steadily grow[2].
At present, with corncob as raw material for producing furfural has been more mature.
Experimental Material.
Meanwhile, since the ionization rate of hydrogen ion of acetic acid is lower and the system is in the weak equilibrium condition, it will reduce the raw materials carbonization phenomenon and improve furfural yield.

Introduction The microwave resonator is also named microwave drying apparatus, and it is an interaction effect space of microwave electromagnetic field and materials, and it is also a working area where materials absorb microwave energy for the moisture instrument [1].
These types of resonators have different characteristics and working areas, when chosen different types of the resonators, the heated materials and working conditions should be considered.
When the microwave resonator is designed, the sizes of heated materials must be firstly considered, and then it is considered how to make the electric field distribute symmetrically in the resonator and how to improve the heating efficiency.
Usually, the heating efficiency decides the maximum size of the box, and the minimum size is decided by the volume of heated materials and distribution characteristic of electric field.
With more modes in the cavity, the distributions of the electromagnetic field are more symmetrical, so the energies from the materials heated by the microwave are also more symmetrical.

Testing Materials and Method 2.1 Testing System A set of power monitoring system of ultrasonic surface rolling was established in this paper to obtain the information such as the actual bearing impact of material surface during processing.
When the vibration of processing tip acts on the material surface, the material perceives the impact and passes to the piezoelectric sensor.
