This Al -free 980nm pump laser have many merits, such as improved catastrophic optical damage level; no degradation due to oxidation of aluminium during fabrication process and laser operation, which is desirable characteristic for multi-step growth; lower electrical and thermal resistance with GalnP cladding; better carrier confinement with GalnAsP confinement layers; Selective chemical etching between GaAs and GalnP maks precisely control for fabrication of stripe geometry lasers.· Calculated the physical parameters of ternary and quaternary III - V compoundsby interpolation formulas based on curve fits or on a linear regression, such aslattice parameter, band gap, and refractive index.· Using luttinger-kohn Hamiltonian-based propagation-matrix method presentedby S.L.

这种无Al980nm半导体激光器可以提高激光器出现腔面损伤所需的能量,消除在生长过程和应用过程中由于Al的氧化而使激光器的使用寿命缩短的问题,便于激光器的多次生长;以GaInP为盖层可以降低电阻和热阻;可以精确的控制GaAs和GaInP之间的化学刻蚀,便于激光器几何形状的控制。

In certain range,the bioenrichment of the mealworm larvae to Zinc in reference to the dosage added in the fodder is accorded with cubic curve relation:Y=181.2517+20.9314X-0.4099X2+ 0.0025X3. And the enrichment ability of T. molitor larvae in reference to the weight is also accorded with the cubic model:Y=35.8325+61.4155X-10.2980X2+0.4434X3. The enrichment of the larvae to Zinc can get to a high level in 2 to 3 days. This is anadvantage to numerous rearing of the mealworm. But we do not find a good rearing way to enhance the rate of bioenrichment to Zinc. And the further research about this is anticipated.

第二部分:采用锌作为添加元素,考查黄粉虫对微量元素的富集规律,结果表明:(1)黄粉虫虫体锌含量在一定范围内随锌添加量增加而呈三次曲线关系,符合三次曲线方程:Y=181.2517+20.9314X-0.4099X~2+0.0025X~3;(2)黄粉虫幼虫对锌富集能力随虫体大小变化而变化,与虫大小亦呈三次曲线关系;Y=35.8325+61.4155X-10.2980X~2+0.4434X~3;(3)黄粉虫虫体锌含量随着锌饲料添加而迅速上升,可在短期2~3天内达到较高水平,对于以黄粉虫为材料进行富锌保健食品生产有很大优越性;(4)本试验并未找到一种较好的锌添加方法来提高锌富集量,这方面的研究有待继续。
