汽车照明防眩的新技术

文章介绍了一种新颖的汽车照明防眩技术，这是汽车前照灯的脉冲化照明所带来全新功能之一。通过利用高速频闪的脉冲氙灯，配合高速液晶电光开关制成的挡光板，让对方照明效果光透过，而挡去大部进入眼睛的外部眩光，从而达到防止眩光的目的。本文详细论述了这种新颖的防眩控制技术，并给出了在实用中多车交会时的处理方法。     

Advances in selective wet oxidation of AlGaAs alloys

We review the chemistry, microstructure, and processing of buried oxides converted from AlGaAs layers using wet oxidation. Hydrogen is shown to have a central role in the oxidation reaction as the oxidizing agent and to reduce the intermediate predict As₂O₃ to As. The stable oxide is amorphous (Al_xGa_1-x) ₂O₃ which has no defects along the oxide/semiconductor interfaces but can exhibit strain at the oxide terminus due to volume shrinkage. The influence of gas flow, gas composition, temperature, Al-content, and layer thickness on the oxidation rate are characterized to establish a reproducible process. Linear oxidation rates with Arrhenius activation energies which strongly depend upon AlAs mole fraction are found. The latter produces strong oxidation selectivity between AlGaAs layers with slightly differing Al-content. Oxidation selectivity to thickness is also shown for layer thickness <60 nm. Differences between the properties of buried oxides converted from AlGaAs and AlAs layers and the impact on selectively oxidized vertical cavity laser lifetime are reported

An improved outer pipe method for expansive pressure measurement of static cracking agentsOA

Static cracking agent(SCA) is actively investigated as an alternative to explosive blasting for rock breakage due to its immense expansion property. SCA can eliminate the negative effects of shock, noise and harmful gases encountered in explosive blasting processes. Accurate measurement and deep understanding of the expansive properties of SCAs are important in their industrial application. An improved outer pipe method(OPM), termed the upper end surface method(UESM), is proposed in this paper t...
