查询词典 Laguerre polynomial

The effects of external rare earth on growth and physiological of Chlorella ellipsoidea and Ceratophyllum demersum were studied. The results implicated that there were apparently negative linear interrelation between the concentrations of Sm, Y and the numbers of Chlorella ellipsoidea, which would best be described as polynomial interrelation at 2～40mg/L concentration range of Sm and 2～20 mg/L of Y. The LC〓 of Sm and Y was respectively 41. 36mg/L and 2. 57mg/L by statistics, which also indicated the toxicity of Y was greater than that of Sm.

外源稀土对小球藻及金鱼藻生长生理影响研究结果表明：(1)中稀土元素Sm和重稀土元素Y处理浓度与小球藻生长量之间存在明显的负线性相关关系；在稀土一定处理浓度范围（Sm为2～40mg/L，Y为2～20mg/L）内，小球藻生长量随培养时间的动态变化符合多项式相关关系；统计计算得Sm和Y对小球藻的半致死浓度LC〓分别为41.36mg/L和22.57mg/L，表明Y对小球藻的毒性大于Sm。

Firstly, three popular ionosphere models (Klobuchar model, IRI and JPL GIM) were compared with grid TEC. Then CNC TEC Map using Kriging method with constant drift, linear drift and quadratic drift were compared with each other. Then TEC map derived from nearest neighbor method, polynomial regression method (order=5) and Kriging method with different temporal resolution of 5 minutes, 30 minutes and 120 minutes were compared.
