Grey water systems

In this paper, a new predicting model of single eutrophic index of water quality is developed by grey systems GM (1, 2) modelling.

本文应用灰色GM(1,2)建模方法，提出了水质富营养化单项指标的一种新的预测模型。

In addition to reducing electricity consumption for air conditioning, the project utilizes rain collection systems, grey-water capture and low-flow fixtures decrease municipal water usage.

除了减少空调用电，该项目还通过利用雨水收集系统，中水捕捉和低流量装置减少市政用水。

To emphasize expatiating on how the method of grey systems analysis works in the estimation of water-gushing amount of the tunnel, then compare the result with two common methods.

论述了隧道涌水预测的基本原理与方法，并重点结合岩溶地区特殊的地质条件对有关方法进行了阐述。
