The evaluation methods of DCD are also described in this paper.
最后给出文本聚类结果描述的评价方法。
Caplan is not opposed to DCD, but said, "we need to have a national standard on how it is to be implemented."
盖普兰并不反对DCD计划,但他也同时指出:“我们还需要制订一个全国通行的实施细则。”
The result showed that DCD promotes the growth of the bacteria and actinomycetes, DCD restrains the growth of the mold.
结果表明:双氰胺对土壤中的细菌、放线菌生长具有促进作用,对土壤中的霉菌生长具有抑制作用。
Ammonium existed in soils for a longer time when DCD used, and the ammonium peak raised when DCD concentration increased.
双氰胺使尿素氮更长时间地以铵态氮形式存在于土壤,且浓度越大铵态氮峰值越大。
The results indicated that adding DCD significantly increased ammonium content and decreased nitrate nitrogen content at the same time.
赤红壤中添加DCD在同一培养时间均能显著降低土壤较高的铵态氮含量,提高硝态氮含量。
