In the batch incubation with addition of Asadsorbing ferrihydrite, the presence of arsenicresistant denitrificator caused an increase in concentrations of Fe and Mn, a decrease in concentrations of NO-3 and As, and a high ratio of As to the total As.

在吸附有砷的水铁矿体系中，反硝化菌所产生的反硝化作用可导致溶液中NO-3含量的降低、Fe含量的升高、As含量降低，且As所占比例增加。

Anaerobic activated sludge was used to cultivate arsenicresistant denitrificator in laboratory.

The most common materials are amorphous silicon (a-Si, still silicon, but in a different form), or the polycrystalline materials : cadmium telluride and copper indium diselenide.

最常用的材料是非晶硅(a-si，依然是硅，但是不同的形式)或者是多晶硅，镝化镉，铜铟砷CIS，CIGS

As two important metals in the catalogue of endocrine disruptor chemicals, the pollution of mercuric and arsenic compounds in aquatic samples are of great concerned.

作为环境内分泌干扰物&黑名单&中的两种重要的金属物质，汞、砷在环境水体中的污染一直是人们关注的热点。

Dissimilatory arsenate-respiring prokaryotes can reduce As to As,chemoautotrophic arsenite oxidizers and heterotrophic arsenite oxidizers can oxidize As to As.

砷是一种有毒元素，其毒性早在2000多年前就被人们所认识和利用。

On the silicon substrate an epitomical layer is made,where IC components are formed subsequently.In an CVDprocess,the silicon substrates places in a vacuum crystal tube are first heated to 1,600°C by high-frequency radio power and then H⒉Cl⒉Si and certain gaseous compounds of As or P is injected into the tube to make a deposit of several um on their surface.Ions of As or P are impurity deliberately added to the singl-crystalline silicon structure to supply electrons that transmit "negative"current in the silicon crystals,which is called n-type silicon.Bcan be added as impurity to produce p-type silicon that supplies holes for transmitting "positive"current.Whether a p--type of an n-type silicon substrate is needed depends on what type of transistors is expected to be manufactured on it:n-p-n type of p-n-p type
