模拟计算结果与实验结果非常吻合，该机理可以正确描述不同的气体组成和反应温度下，H_2选择性还原NO 的反应进程和还原产物分布。

P species, main as Ca-P and organic P forms, showing rego〓 pollution and karst area of lake watershed, inorganic P〓 related to Ca〓, Al〓, Fe〓 content in the overlying water, sediments is not a simple reservoir of dissolved phosphate and particle phosphate, near the interface, near 98% of total P existed as active forms, they may release to overlying water through reduction dissolution, deadsorption in the period of early diagenesis, only 2% of P as fixed forms, which mainly remained in the sediments, sediment was an important resource of nutrients of ovrelying water.

高原湖泊沉积物中的磷以有机磷和Ca-P形式存在为主，反映了高原湖泊流域污染和碳酸盐地区的整体背景，无机磷形式与水体吸附体Ca〓，Al〓和Fe〓的含量有关。底部沉积物不是溶解性磷酸盐和颗粒磷酸盐的长期储存场所，几乎有98%的磷是活性的形态存在，它们通过早期成岩作用在还原条件下还原，溶解和释放又重新回到上覆水体，只有2%的磷以固〓态的形式稳定保存于沉积物中，因此，沉积物为水体营养程度的重要来源。

Androgen ablation therapy with leuprorelin acetate caused a decrease in the expression of both 5α-reductases. Our data indicate that different type of 5α-reductase is involved in the pathogenesis of BPH and PCA.

根据我们的结果可以认为在良性前列腺增生中以Ⅱ型还原酶的作用为主而Ⅰ型还原酶则可能在前列腺癌的发生中起主要作用。

NiRs are divided into two different types based on their prosthetic groups, namely heme-containing nitrite reductases (cd1-NiRs) and Copper-containing nitrite reductases.

根据辅基的不同， NiRs分为血红素cd1型亚硝酸还原酶(cd1-NiRs)和铜型亚硝酸还原酶两种。

The results showed that the activities of urease, nitrate reductase, nitrite reductases and the yield of above ground plants were the highest with the fertilization pattern of taking 50 percent nitrogen from organic fertilizer and the other 50 percent nitrogen from urea.

结果表明：采用50%的N由有机肥提供，50%的N由尿素提供的施肥模式时，黑麦草根际土壤脲酶、硝酸还原酶、亚硝酸还原酶活性最强，黑麦草地上部产量最高。

BST16 was also proved to encode gene of PSII lOkD protein by protein prosite and conserve domain analysis. The protein encoded by BST16 contained a conserve domain PsbR of PSII lOkD protein from 48 to 140 and its carboxy terminal had an ADH_SHORT prosite of Short-chain dehydrogenases/reductases family signature from 94 to 122, which showed the protein encoded by BST16 would be a reductases.

对该基因可读框架编码的蛋白进行功能位点和结构功能域的分析，同样证明了该基因为PSⅡ 10kD蛋白编码基因，其氨基酸摘要序列 48刁位含有一个保守的光合系统＊ 10kD蛋白结构域 PSbR，在蛋白的猿基端有一个保守的短链脱氢酶／还原酶家族特征序列ADHSHORT（Short－chain dehydrogenases／reductases family signature），位于94－122位，说明了该蛋白可能具有还原酶活性。

The inhibition of acidity to the Pu reduction is less in comparison with other studied organic reductants, hence it can be expected that HU has great advantage for the application in a relatively higher acidity process.

由于HU还原Pu的速度非常快，所以，溶剂萃取法求得的动力学方程可能较为准确，而且与一NHOH取代化合物还原Pu的一般机理相符。

The fluorescent response of BQC is insensitive to various biological thiol reductants.

对生理环境中所存在的各种不同硫化物做还原的测试，隐藏型萤光探针不会发生氧化还原反应，依然保持专一的性质。

Amongst all the pos-combustion techniques, SCR method is one of the common practices. Yet, during the process of most SCR method, the corrosive reductants can lead to further pollution. As a result, developing alternative control technology is of the highest priority to effectively reduce NOx emission for the industry.

其中又以选择性触媒还原法较为普遍，但是其在还原过程中还原剂的溢散、腐蚀等问题还有待解决，所以再找寻更合适的技术是刻不容缓的事，因此如何有效降低氮氧化物之排放，对产业界乃是一项挑战。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
