例句與造句

1. 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
   生物評價結果認為，千島湖浮游藻類平均密度較同類營養(yǎng)水平的淡水水體高，其所有取樣點浮游藻類平均密度都10 ~ 6個? l ，國內外一般認為當浮游植物平均密度10 ~ 6個? l時，其已經達到富營養(yǎng)化水平，因此單從浮游植物密度來看，可以認為千島湖已達到水體富營養(yǎng)化。
2. 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
   給出了滾筒調控靜態(tài)數學模型，并根據調高機構的調控特征方程與采樣點間頂底板變化特征方程的差異，給出了在其采樣區(qū)間內的指令式控制策略，其方法的規(guī)則條日少、簡單易運算、符合實際控制要求。
3. 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
   時域成像技術以超寬帶脈沖源作為入射波源，用吸收邊界條件來界定計算域，而當采樣點遠離計算區(qū)域時，需要通過近?遠場的轉換技術把近場等效面上的信息轉換到遠場，本文采用簡單而實用的柱面波外推法作為近?遠場的轉換方法，收到了較好的效果。
4. 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
   各向同性分析的結果表明： 12種(除全氮)土壤養(yǎng)分在一定的范圍內觀測值之間存在著空間相關性，變異函數( h )隨間距增大而增大，且有基臺值，說明存在空間變異結構特征，在50m的采樣間距內存在空間相關性。
5. It's difficult to find sampling spot in a sentence. 用sampling spot造句挺難的
