哑铃湾网箱养殖使底层海水中TO C、SS、有机污染物和溶解态氮磷营养盐都有不同程度的增加,春、夏、秋3季D O有不同程度的下降,SS、C O D M n、N H4+、D IN、D IP的增加相对更显著,而对pH值、盐度、水温和冬季D O的影响较小;在水质状况上,D O、B O D5受影响最大,其次是D IP;养殖期较长的网箱区底层海水在春、秋2季已达到富营养化水平。
2.
Based on field investigation in the cage culture area,Yaling Bay,from Apr 2002 to Jan 2003,the percentages of various forms of phosphorus in bottom water of cage culture area in total phosphorus(TP) and total dissolved phosphorus(DTP) were calculated.

3) aquifer floor
含水层底
4) bottom aquifer
底水层
6) bottom aquifer
底部含水层
1.
Through the analysis of engineering geology and hydrological geology in Yanzhou minei,t is found that the main reason for shaft damage is the compression of bottom aquifer and there is a law between head loss of bottom aquifer and shaft lining damage.
通过对兖州矿区的工程地质水文地质的分析可知,立井井筒破坏的主要原因为井筒周围底部含水层的压缩,且含水层水头的降低与立井井筒的破坏直接存在一定的规律,底部含水层的压缩在立井井筒内产生附加应力,此附加应力造成立井井筒的变形破坏,通过拉格朗日法对立井井筒的破坏过程进行数值模拟,通过计算得到立井井筒破坏过程中各个影响因素的变化规律,从而得到立井井筒的破坏规律,为兖州矿区立井井筒破坏的治理提供理论基础,而且在立井井筒的破坏机制分析及防治方面发挥重要的作用。
