It is very important that the heat sources property on heat lamination height to multi-polluting heat sources displacement ventilation.
本文建立了多污染热源置换通风的三维稳态、紊流数学模型,根据数值解分析三热源表面温度、热流量及位置变化对热力分层高度的影响,以提高多污染热源置换通风的效果,并进行实验验证。
Furthermoreu,sing extreme value theoryt,he extreme value distribution and pollution risk probability of the COD were presented.
研究结果表明:渤海湾COD季节之间变化不明显,5月、8月及10月的COD具有指数分布特征;COD年际间变化呈下降趋势,与同期COD排放变化趋势吻合;COD的污染风险概率符合Pareto型超阈值分布函数。
By means of applying different levels of pig manure and cattle manure to potted ryegrass,the paper studied the capacity of absorbing organic manure of ryegrass and secondary pollution risk by determining the amount of the nitrogen and phosphorus absorbed by ryegrass,and residue in soils and losses.
对盆栽黑麦草施以不同水平的猪粪和牛粪两种有机肥料,通过测定黑麦草对氮和磷的吸收量、土壤的残留量及粪肥中氮和磷的损失量,研究了黑麦草对养殖场粪肥的消纳吸收能力及可能产生的二次污染风险。
In this paper, it also indicated intensive system became the all-important resource for land pollution risk and animal manure production load to cropland.
廊坊和石家庄的规模养殖产生的粪尿比例在河北省位于前列,分别为72%和59%;河北省畜禽养殖对于农田的污染风险主要以规模养殖为主,规模养殖下农田负荷量为114。
