It was constructed by drilling and blasting method using the parallel heading at No.

In this article,some im- portant items about optimizing design topics,raising teachers guidance level,training students independent a- bility,making management systems sound are discussed,which aim to enhance quality of graduation design.

Laser beam addition of planar waveguides with fractional self-imaging

In order to improve the detection sensitivity and increase the response speed of the biosensor,based on the theory of planar waveguide,the zone energies of the evanescent fields in the single mode and multimode of the planar optical waveguide were compared under the same condition by using the principle of the evanescent field applied to the biosensing field.

GeO2-SiO2 planar waveguide technology is reviewd in this paper in terms of its history andprospects and application in integration optics.

Myoelectricity study on wearing flat bite plate under different raised distances in deep overbite therapy

Objective To study the root resorption caused by edgewise appliance combined with flat bite plate treatment.

The effect of treating deepbite corrected by rackety chair archwire only or together with flat bite plate and the result was compared.
