The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

In classical music I always admired Mussorgsky's unorthodoxy, unpredictability and disrespect of rules, and a few other Russian composers such as Shostakovich (the second tempo of his 8th String Quartet and Chamber Symphony op.110/110a electrocuted my imagination at least as much as the beginning of his 5th Symphony must have remained stuck in Morrissey's mind, when he sampled it for 11 minutes on the opening song of his "Southpaw Grammar" album), Prokofiev (whose exceptional melodic ingeniousness influenced me, but must have pleased Sting too, as he borrowed the theme of Prokofiev's "Lieutenant Kijé" for his hit "Russians") and Mosolov (whose mid-1920s piece "Iron Foundry" is pure Prog-Rock à la Magma, Art Zoyd, Univers Zero).

古典音乐家里面我一直十分欣赏Mussorgsky的叛逆、不可预测以及他对常规的无视，还有少数俄罗斯作曲家，比如Shostakovich，（他的C小调第八弦乐四重奏作品第110号/110a的第二部分 [1]强烈激发了我的想象力，这种激发不亚于他的第五交响曲[2]的开始部分对于Morrissey[3]的影响，那段旋律令他印象如此深刻以至于他将11分钟的采样放在了他的专辑《Southpaw Grammar》中。）Prokofiev（他格外出色天才一般的旋律影响了我，但是Sting肯定也获益匪浅，因为他也在自己的热门单曲"Russians"俄罗斯人中借用了Prokofiev 的"Lieutenant Kijé"三驾马车[4]），和Mosolov[5]（他创作于1920年中期的作品"Iron Foundry"是纯粹的前卫摇滚à la Magma，Art Zoyd，Univers Zero）。
