The key components in laser gyro is He-Ne ring laser, and the reciprocal action theory between light and medium is the base in studying the ring laser, use the Lamb half classical theory, and on the base of density matrix theory, the optical Brounch equation was established, which described the movement of amplifying medium atom in the ring syntonic cavity, and according to the medium polarize theory the self consistent equations was deduced, which describe the light intensity and phasic of the counter-propagating wave. On the basis of this equations, adopted the simulation software MATLAB and virtual instrument programming language LabWindows/CVI, we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium, mode pushing effection, burned hole effection and pattern competition, lock-in of frequency and the characteristic of light intensity and phasic of the counter-propagating wave in laser gyro.

METHODS From October 2004 to January 2008, 24 patients with complex congenital heart disease underwent RHB. The dignoses of patients included tricuspid atresia, single ventricle, and so on. Among them, 8 cases were found ectopia cordis. Opreation precedure included bidrectional Glenn shunt (19 cases) and total caval pulmonary connection (TCPC,5 cases). In the 24 cases, 16 patient underwent off-pump operation. RESULTS Total hospital mottality was 4.2%.
