However , co-application of WTR and biosolids may result in P deficiency in soil and plant AI toxicity with increasing WTR rate .

但随着水处理残渣施用量增大，又有可能导致土壤P不足或对植物的铝毒作用。

The present situation of the construction cost management and calculation model of projects in China and the pricing method of statement form to adapt to the situation after China entering WTR are discussed .

主要对我国目前工程造价管理与计价模式的现状和如何推行工程量清单式计价方法以适应入世后的要求进行了论述和探讨。

The effects of anode hydrogen flow rates , environmental temperature and relative humidity on the performance of the self-humidifying MEA were investigated . Then , the area of WTR was optimized .

研究了阳极氢气流速、环境温度和环境相对湿度对自增湿膜电极性能的影响，并对水扩散区面积进行了优化。

Co-application of water treatment residuals ( WTR ) with biosolids can reduce the buildup of P in soil as well as the risk of P losses to surface and ground water .

虽然水处理残渣与有机污泥混施可以减少土壤P过量积累以及P对地表和地下水的污染。

Powders and composites PP / SBS , WTR / SBS , WTR / PP / SBS were prepared and effect of pan-milling on WTR / PP / SBS composite was especially studied .
