砷

While arsenic-resisted strain can be filtrated from tame soil, it can provide theoretical basis for the bioremediation technology.

同时从驯化土壤中筛选出抗砷优势菌，为微生物修复技术提供理论依据。

Multiple CSCCs carry a high risk of subsequent primary skin cancer. CSCCs arising in a scar have higher rate of recurrence or metastasis than those occurring in actinic keratoses. A patient presented with primary CSCCs on the ankle and wrist.

多处原发性皮肤癌病患比起一般皮肤癌患者，有更高的机会发生次发性皮肤癌，且源於疤痕或慢性砷中毒的扁平上皮细胞癌，其侵袭性、复发率、转移可能性，及并发其他疾病的可能性也比源於紫外线暴露者为高。

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.

土壤经自然风干，粉碎过100目筛，取适量试样于盛有0.5g艾氏试剂的瓷钳埚中，再取2g艾氏试剂覆盖试样，置高温炉中灼烧，冷却，水浸提，砷铈氧化还原分光光度法测定碘含量。

Notice: Mercury is dangerous, more poisonous than lead or arsenic!!!!

注意：水银是很危险的，更比铅或砷更毒！！

Arsenic is one of the most notorious elements on account of its human toxicity,depending on its speciarion.

近年来人们逐渐认识到砷元素在环境和生态中的效应并不取决于它的总水平，而是取决于它存在的形态。

Selenium, some arsenic, all these nasties, heavy metals, pesticides are in that lakebed.

硒，砷，所有脏东西，重金属，农药布满了整个湖床。

To prevent secondary pollution, the stability of arsenic-bearing precipitates should be further studied.

为防止处理后的含砷废渣二次污染，必须进一步研究其稳定性。

Traditional copper surface roughening treatment involve the use of arsenide-containing electrolyte which is harmful to environment.

对铜箔表面进行粗化处理，传统的粗化工艺中要使用砷化物，不仅操作不便而且危害环境。

The present invention adopts ammonium salt solution as leach, and adopts the liquid-phase oxidation activating agent formed from surfactant sodium ligno-sulfonate or sodium dodecyl sulfonate, liquir phase oxidation catalyst Cu(2+) and sulfur-extracting agent tetrachloroethylene to implement quick leaching process of sulkfide mineral in gas-liquid-solid three-phase reactor, all the sulfurs contained sulfide in mineral powder can be converted into elementary sulfur and sulfuric acid radical, the contained zinc, copper, nickel, cobalt, lead, cadmium and silver can be changed into soluble salt, and fed into leach or remained in the leaching out slag.

本发明涉及的有色金属硫化矿的铵盐液相氧化直接浸出方法，其特征在于：采用铵盐溶液作浸出剂，采用由表面活化剂木质磺酸钠或十二烷基磺酸钠，液相氧化催化剂Cu2+、萃硫剂四氯乙烯组成的液相氧化活化剂，在气液固三相反应器内，实现硫化矿的快速浸出过程，矿粉中各种硫化物所含的硫转变为单质硫和硫酸根，所含的锌、铜、镍、钴、铅、镉、银等变成可溶性盐类进入浸出液中或留在浸出渣中，消除传统流程中二氧化硫，硫化氢，氮氧化物及含砷含汞含铅等有毒烟气的排放。

So for a long period,the medical values of arsenic were covered with its toxicities and side effects.

因此，砷剂的药用价值长期以来一直被其毒副作用所掩盖。

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。
