英汉例句

• This paper reports the effect of DCD in seedling stage to soil microorganism of bacteria, mold and actinomycetes, and the concentration changes of both ammonium nitrogen and nitrate nitrogen in soil.

  实验研究了双氰胺在玉米苗期对土壤微生物细菌、霉菌和放线菌的影响，及对土壤中铵态氮和硝态氮贮量变化的影响。

• The second is UD treatment because the DCD could delay the peak period of urease activity, reduce urease activity in the early days and it also could inhibit the amount of AOB significantly.

  其次为UD处理，配施DCD能明显推迟脲酶活性高峰出现时间并降低前期活性，同时能显着抑制氨氧化菌生长。

• 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着降低土壤较高的铵态氮含量，提高硝态氮含量。

• Nitrogen application and NDSA fertilization had slightly effect on the soluble sugar content in celery, but DCD could significantly increase it.

  施氮和ndsa施肥法对芹菜可溶性糖影响不大，但添加dcd可明显增加芹菜的可溶性糖含量。

• 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。

• In addition, the mechanism of DCD remains unclear duo to diversity in clinical manifestation, high comorbidity rate and discordance in classification of subtypes of the disease.

  而且，由于儿童发育性协调障碍临床表现的多样性，与其他疾病的高并发率以及亚型分类上的不一致导致其发病机制至今未明。

• The coated urea MEISTER combined with dicyandiamide (DCD) didn't further increase maize and rice yields. Moreover, the nitrification inhibition effect of DCD was not steadily.

  MEISTER包膜尿素配施DCD没有进一步增加玉米和水稻的产量，DCD抑制土壤硝化作用的效果不稳定。

• Dynamics of different soil nitrogen pools after application of urea with DCD or organic materials were studied by aerial incubation method.

  采用好气土壤培养试验，研究了尿素配施有机物料和DCD条件下土壤不同氮库的动态。

• 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。
