Nitride semiconductors, such as GaN (Eg~3.4 eV), InN (Eg~0.7 eV), AlN Eg~ (6.2 eV) and their alloys [1-4], are one of the best candidates to meet these needs due to their superior materials properties.
Improvement of the these materials will make one step closer to the practical applications in solar cells covering the whole solar spectrum [5], optical fiber communication laser diodes with high wavelength stability as a function of the temperature [6], and various electronic devices with high electron mobility [7].

However, with respect to the simplified mechanical model in the engineering structure, the inner force is relatively large, then its influence on the bend should be taken into consideration.
The reasonable range of horizontal section altitude is between 20m and 30m in Weihuliang coalmine, it is safe and appropriate to select lower limit 20m in engineering practice, coincides with the calculated results of this paper.
In accordance with the structural form of geotechnical engineering structure, rock material and the existing condition of overlying strata, we apply the analytical solution into the engineering project and make the stability theory more useful in engineering respect

Laser Array and Key Principles for Smoke Imaging Test Lu Bin1a, Wang Lin1b and Tan Wei2c 1Mechanical engineering department of Navy aeronautical and astronautical university, 264001, Yantai City, China 292853th unit 125106, Xingcheng city, China e-mail: apainel@sina.com, bwanglin188@163.com e-mail: cTanwei1982@163.com Keywords: Laser Array Control, Smoke Accurately Measure, Light Beam Homogenization, Non-Uniformity Correction, Shaping Abstract: The scene of single laser beam light is too small for the smoke field testing and the synchronization problem also unavoidable when it works at scanning way.
Follow in the paper introduce the design and key principles to measure smoke area source which full of scene of CCD (10º×10º) at 20m distance in the field testing smoke by 3×3 beam homogenous enlarge shaping laser array.
So here one of the key principles of laser beam should be part single laser beam equably to lower it power.
σe Is extinction rate of smoke, it directs proportion to thickness of smoke materials.
