To put forward long term forecasting, investigation on emergence amount and total distribution area of over winter larva of meadow moth is necessary. 据此提出今后要搞好草地螟长期预报,必须跟踪观察各代幼虫越冬的比率和面积大小。
After elaborated green coefficient analysis methods, including green the direct consumption coefficients and completely consumption coefficients, green direct distribution coefficient and total distribution coefficient, green influence coefficient and sense degree coefficient three supporting method. 之后阐述了绿色系数分析方法,包括绿色直接消耗系数与完全消耗系数,绿色直接分配系数与完全分配系数,绿色影响力系数与感应度系数三种配套方法。
By inspecting the total distribution of form deviation, the reasons are analyzed. The conclusions are different between the uncertainty distributions gained by use of order statistics and evolution model method of form errors. 通过对形状偏差的总体分布情况的考察,对利用秩统计分析得到的形状误差的分布与川形状误差的评定模型得到的分布不一致的原因进行了分析,提出了应用的前提条件。
Optimal Industry Total Distribution(TD) Model of Water Pollutants 水污染物总量行业优化分配模型研究
The total amount control of river basin water pollutants is the focus of river basin water environmental management, and river basin water pollutant total distribution is the core work of the implementation of total quantity control. 流域水污染物总量控制是流域水环境管理的主要内容,而流域水污染物总量分配是实施总量控制的核心工作。
