sampling spot meaning in English
取样地点
取样点
Examples
- 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。 - Static mathematic model of drum accommodation and control is presented , and instruction model control strategy of sample intervals is presented based on differences between characteristic equations of lifting frame and characteristic equations of top and bottom board change among the sampling spots , the rules of this method are few , simple , easy to operate and meet controlling demands
给出了滚筒调控静态数学模型，并根据调高机构的调控特征方程与采样点间顶底板变化特征方程的差异，给出了在其采样区间内的指令式控制策略，其方法的规则条日少、简单易运算、符合实际控制要求。 - In order to validate the feasibility of the novel algorithm , ultrawide band pulse wave is used as incident wave . computational domains are limited by absorbing boundary condition . the transformation technique from near zone to far zone is used when the sampling spot is outside of the computational domains
时域成像技术以超宽带脉冲源作为入射波源，用吸收边界条件来界定计算域，而当采样点远离计算区域时，需要通过近?远场的转换技术把近场等效面上的信息转换到远场，本文采用简单而实用的柱面波外推法作为近?远场的转换方法，收到了较好的效果。 - The analyst of isotropy indicated that the sample spots of 12 soil nutrient contents ( except total nitrogen ) were correlated in given spatial range . the semi - variogram values increased when the distances were enlarged , and nugget lied in , which meant the existence of spatial variability structure , and sample spots were correlated in the 50 - meter of sampling distance
各向同性分析的结果表明： 12种(除全氮)土壤养分在一定的范围内观测值之间存在着空间相关性，变异函数( h )随间距增大而增大，且有基台值，说明存在空间变异结构特征，在50m的采样间距内存在空间相关性。
