Result On the whole, the collected sludge was a kind of organic fertilizer with high nutrient content, which contained rich organic matter (296.84g/kg on average), high nitrogen (48.33g/kg on average), medium phosphorus (18.94g/kg on average), low potassium (14.17g/kg on average). The pH value of the sludge was all in 5.95-7.73, being between subacidity and alkalescence, and application in the garden soil could not produce great influence on the acidity-alkalinity of soil.
结果]总体上所采集污泥是一种富含有机质(平均为296.84g/kg)、高氮(平均为48.33g/kg)、中磷(平均为18.94g/kg)、低钾(平均为14.17g/kg)的养分含量颇高的有机肥。pH值在5.95-7.73,处于微酸性和微碱性之间,在园林土壤中施用,不会对土壤的酸碱度造成大的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
