In this paper, we have investigated and discuss the appropriate conditions under which the developing reaction to responds to Phospho Vando Molybdic acid and basic dye malachite green in aqueous solution by conducting experiments, through which the best quantity about addition of reagents can be fixed.

研究了磷钒钼酸与碱性染料孔雀绿在水溶液中的显色反应，确定了最佳反应条件，并将这种方法应用于复混肥中磷含量的测定，试验结果表明，此方法的灵敏度高、重现性好、准确度高。

The effects and performances of dephosphorization of the common coagulant and the flocculants: the calcium salt, the molysite and the aluminum salt and polyacrylic amide were studied on the post-positioned precipitation of municipal sewage which was processed through biological treatment.

本实验以常用混凝剂及絮凝剂：钙盐、铁盐和铝盐及聚丙烯酰胺为研究对象，研究它们对经生物处理后的城市生活污水出水，进行后置沉淀除磷的性能及除磷效果。

The results showed that CRMP had higher phosphorus availability in soil and the changes ofavailable P concentration in both root zone and non-root zone soil were more reasonable during the sorghum growing season as compared to common monoammonium phosphate.

与普通磷酸一铵相比，控释磷酸一铵施入土壤后磷的有效性较高，无论是近根区还是非根区土壤有效磷随时间的变化分配更趋于合理。

A P enrichment treatment was carried out in the greenhouse simultaneously. 300ppm P as monocalcium phosphate were applied in each of these eight soils and kept in field capacity for 5 months.

採取本省中、南部代表性石灰质土壤八种，分别加入0、20及300ppm p后，置於塑胶罐中，保持田间容水量状態，以30℃定温孵育，定期取出测定其有效磷及无机磷型態。

Methyl-5-ethyl-2-thiouracil,m.p.211°,was prepared according to the direc- tions of Johnson and Baily.4-Methyl-5-ethyl-uracil,m.p.236°,was formed in a 81% yield from 4-methyl-5-ethyl-2-thiouracil by boiling the latter with an aqueous solution of monochloroacetic acid.4-Methyl-5-ethyl-uracil reacted with phosphorous oxychloride and phosphorous pentachloride,giving 4-methyl-5-ethyl-2,6-dichloropy- rimidine in a 79% yield.

14-甲基5-乙基-2，6-二氯代嘧啶曾用磷醯氯和五氯化磷与其相应的2，6-二羟基嘧啶作用制取。(2)4-甲基-5-乙基-2，6-二氯代嘧啶与醇钠作用，极易转变成4-甲基-5-乙基-2，6-二烷氧基嘧啶。(3)4-甲基-5-乙基-2，6-二甲氧基嘧啶和2-氧代-3，4-二甲基-5-乙基-6-甲氧基嘧啶在高温时重排成其稳定构型的的异构体：1，3，4-三甲基-5-乙基-2，6-二氧代嘧啶。

Phytase can add to the feed of monogastric animals and hunan food. The addition of phytase to feed and food can resolve the antinutrition of phytic acid, increase the bioavailablity of protein and minerals, decrease animals' fecal phosphorus excretion and reduce environment pollution.

植酸酶可添加于食品与饲料中，能消除因不能降解的植酸所引起的抗营养作用，提高机体对蛋白质及多种微量元素的利用率，降低粪便中磷的含量，从而减少环境中磷的积累污染，有利于保护生态环境。

The results show that the bittervine can absorb and metabolize a large quantity of glyphosate. If the glyphosate metabolite AMPA in the plant is used as an index, then the moraceae has the best metabolic effectiveness. The next effective is the bidens pliosa; the worst, the bittervine.

由研究成果显示优势植物小花漫泽能吸收及代谢大的嘉磷，但如果以植物体内嘉磷代谢物AMPA为指标观察，则发现葎草有较好的代谢成效，其次为咸丰草，最差的是小花漫泽。

The coefficients of the function were determined by multivariant stepwise linear regression. Effect of alloying elements was quantitatively demonstrated.

磷、铜提高钢的耐大气腐蚀性能；硫急剧降低钢的耐大气腐蚀性；硫、磷含量在很小范围内即有明显作用。

Compared with non-mycorrhizal seedlings, the ratio of nitrogen and phosphorus in mycorrhizal roots increased, but reduced in stem and leaves.

与无菌根幼苗比，所有菌根幼苗根的氮、磷分配比例增加，而茎和叶片的氮、磷分配比例减少。

But for Myriophyllum spicatum, the optimal concentration of phosphorus was 0.4 mg·L-1. At 0.2 mg·L-1phosphorus, the height and root-length of Hydrilla Verticillata was greater than that of Myriophyllum spicatum, while at 0.4 mg·L-1 phosphorus the reverse was true.

两种沉水植物株高和根长增加量在磷质量浓度小于0.2 mg·L-1时，表现为轮叶黑藻大于穗花狐尾藻；当磷质量浓度大于0.4 mg·L-1时，表现为穗花狐尾藻大于轮叶黑藻。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
