The model of photon-induced refractive index change based on GaAs materials is presented briefly, then the model based on GaAs/AIGaAs quantum wells materials is deeply analyzed by treating the effects of photon-excited carriers self-consistently. Furthermore, the propagation characteristics of multi-quantum well waveguide is invested, and the low-loss multi-quantum well rib waveguide deeply etched is also designed by using the spectral index method.

在简要分析了基于GaAs材料的光致折射率模型的基础上，通过自洽的方法，重点研究了基于GaAs/AlGaAs多量子阱材料的光致折射率模型；其次分析了量子阱波导传输特性，利用谱折射率法设计低损耗的深刻蚀脊形量子阱波导。

Avril, who did the indelible-mark-a-deux thing just last month with not-quite-ex-husband Deryck Whibley, had her wrist permanently etched with a lightening bolt and the No. 30; Brody followed suit by getting a matching bolt below his ear.

艾薇儿，上个月做了不可磨灭的事情（和还不算是前夫的德里克#惠布利一起），让人在她的手腕上永久地蚀刻了一道闪电；布罗迪随后得到了一道匹配的闪电，就在他耳朵下面。

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓＜1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓＜0.5Ma, T〓A＜850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.

在扬子地台&江南古陆&克拉通化时，金刚石开始生长，其生长与保存的平均温度T〓在1200℃左右；期间由于地台的活动，生长的温度压力条件发生了多次变化，使金刚石出现多次生长、停顿；夭折的母岩上侵活动使金刚石受到熔蚀作用；在金刚石形成的晚期，T〓值下降到1050℃以下，出现了另一次金刚石的生长期，在临近金刚石母岩上侵时T〓＜0.5Ma，温度进一步降到850℃以下，使Ⅰb型金刚石得以保存；在金刚石形成期间还有过碎性变形发生；金刚石形成后部分样品经过了塑性变形；金刚石在上侵过程中，遭受了强烈的熔蚀；在母岩露出地表，形成沉积砂矿时，受到了放射性物质的辐照，先形成表层的绿色斑点、壳层，后经过中低温的热变质作用，大部分绿色转化为褐色；现代河流作用对沉积砂矿进一步改造，形成现在的细谷型砂矿。

If need partial hoodwink the acid etched, it must match the silk-screen press, spread the printing ink machine and dryer and so on.

机器的大小：根据瓶型的大小和度的快慢决定。如需局部蒙砂，需配丝网印刷机、涂油墨机、烘干机等。

One of them is based on etched porous alumina and carbon-gold-carbon compound film. The alumnia film surface is composed of rows of valleys with diameter of about 300 nm, and is realized by etching porous alumina in diluted phosphorous acid.

第一种阴极采用基于多孔氧化铝和无定形碳的双层传导薄膜，其中氧化铝薄膜的表面具有横向尺寸为300 nm的特殊凹陷结构，是对常规多孔氧化铝薄膜进行腐蚀形成的。

The idea of analysing or synthesising small quantities of chemicals in a chip-sized apparatus is not new, but labs on chips have conventionally relied on systems of tiny pipes etched into them to move the chemicals around.

在芯片大小的仪器上对少量的化学物质进行分析或人工合成这一概念并不算新，但是传统的片上实验室所依赖的系统是通过细微的蚀刻通道来导引化学物质的移动的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
