| 5. | Conclusions : firstly , now the nutrition status of chinese people is in a low level and there is a big difference between city and county , that is the nutrition level of citizen is much better than farmer ' s
通过研究得出以下结论： 1 、目前我国居民的食物营养状况还处于较低水平，城乡营养状况差别显著，城镇居民的营养水平高于农村居民。 |
| 6. | The following were the results . ( 1 ) according to water quality assessment , in general , water quality was very clean in qiandaohu lake , and the majority of all sampling points were oligotrophic
本研究得出如下结果： ( 1 )水质评价结果表明，千岛湖总体上水质优良，大多处于贫营养水平，只有新安江进入千岛湖的入口处街口处于中-富营养水平。 |
| 7. | Pyramid of biomass a type of ecological pyramid based on the total amount of living material at each trophic level in the community , which is normally measured by total dry weight or calorific value per unit area or volume , and shown diagrammatically
生物量金字塔：指基于群落每个营养水平上有生命的物质总量的一种生态金字塔类型，通常通过总干重或者每单位面积或体积的生热量值来衡量，并用图表表示出来。 |
| 8. | The results showed that the trophic lenel of lake taihu was in the transition state , from meso - eutrophic to eutrophic , of which the meso - eutrophic made up about 70 % of the total are . the eutrophic and hyper - eutrophic waters accounted for 10 % or so
结果表明，太湖营养水平处于中富向富营养过渡状态，中富面积约占全湖面积的70 %以上；夏季富营养及重富营养水域出现在北部湖区的梅梁湖、五里湖和西部沿岸，约占全湖面积的10 % 。 |
| 9. | The results of this experiment showed that the nutrition level had a certain effect on weight gain , feed conversion rate and lactation weight loss in every stage during gestation , and the effect of metabolic weight and average daily feed intake on sow ' s gestation weight gain during early days of gestation period was significant ( p < 0 . 05 )
结果表明，不同的营养水平影响到妊娠各阶段增重、日增重和料肉比以及泌乳损失，妊娠前期代谢体重、日均采食量对泌乳损失的影响显著( p < 0 . 05 ) 。 |
| 10. | Only the water at jiekou had been eutrophic . the result of biological assessment was that the average density of phytoplankton at all the sampling spots was more than 1 , 000 , 000 per litre , indicating that the lake was eutrophic going by the population density . but this density of phytoplankton was higher than that in similar lakes at the same pollution level
生物评价结果认为，千岛湖浮游藻类平均密度较同类营养水平的淡水水体高，其所有取样点浮游藻类平均密度都10 ~ 6个? l ，国内外一般认为当浮游植物平均密度10 ~ 6个? l时，其已经达到富营养化水平，因此单从浮游植物密度来看，可以认为千岛湖已达到水体富营养化。 |
