将电镀废水中的六价铬还原成Cr，用化学沉淀法和絮凝法将其转化为Cr3沉淀，通过硫酸酸化，结晶为高纯硫酸铬，作为皮革工业的铬鞣剂。

The results reported before showed that phyco-bilins are intermediades in the biosyn thesis of phycobilip-roteins and the thioether formation of phy cobilins are thelast step of the chromoprotein biosynthesis.

实验证明在藻胆蛋白生物合成过程中，藻胆色素是中间体。藻胆色素的硫醚键形成是其过程的最后一步。

Under optimal conditions mixtures containing eight inorganic anions, six amino acids such as arginine, histidine, cysteine, methionine, tryptophan and proline with positive or negative charge and four basic proteins such as lysozyme, cytochrome c,α-chymotrypsinogen A and myoglobin were separated completely.

经优化，用中等浓度的中性缓冲液分别成功地分离了八种不同的阴离子Br〓、NO〓、NO〓、SCN〓、MoO〓、BrO〓、WO〓和IO〓；六种带不同电荷的氨基酸如精氨酸、组氨酸、半胱氨酸、甲硫氨酸、色氨酸和脯氨酸；四种碱性蛋白质如溶菌酶、细胞色素c、抗凝乳蛋白酶原A和肌球蛋白。

Because the dimeric form is the active form to exert its biological activities, many trials failed to express TGF β s in prokaryotic systems because of their complex folding manner and disulfide patterns. In 1991 Cerletti and coworkers from Ciba-Geigy Corporation in Switzerland successfully finished the functional expression of human TGF β 2 in bacteria, but the details are protected by the patent.

由于双体是其发挥生物活性的形式，TGF β复杂的折叠方式和二硫键配对使其早期原核基因工程研究都以失败而告终。1991年，瑞士Ciba-Geigy公司的Cerletti等成功完成了人TGFβ2基因的细菌表达，但其技术细节被专利加以保护。

Although pyrite cinder is industrial waste, its also a kind of potential resource.

硫铁矿烧渣虽为一种工业废弃物，也是一种潜在的资源。

Its one of the promising utilization methods of pyrite cinder to use its high iron content in synthesizing PFS.

利用烧渣中较高含量的铁元素进行无机高效水处理剂PFS的开发，是硫铁矿烧渣最有前途的综合利用途径之一。

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。
