剩余产量 meaning in Chinese
surplusyield
Examples
- Will the world market absorb production in excess of domestic needs at profitable prices ?
世界市场能否以有利的价格吸收入国内需求以外的剩余产量呢？ - The paper compares the most popularly used surplus production models using simulated data and swordfish , xiphias gladius , fishery data in the north atlantic ocean
本文应用目前常用的四种剩余产量模型对五种渔业条件下的渔业生物种群及北大西洋箭鱼种群xiphiasgladius评估结果作了比较。 - Analysis of 6 fishery scenarios showed that the re index could correctly indicate the validity of the models results ; however the coverage index could not work well when regression models made blunder
对六种渔业的研究表明re指数能比较正确的指示剩余产量模型的评估效果，而coverage指数不适用当模型回归出现重大误差的情况。 - The author tentatively explored the suitable fishing condition for the models to stock assessment . to make reasonable estimation biologically , the fishery population must experience over explored stage and stock recovery stage
作者初步探讨了剩余产量模型作出合理评估的渔业条件，认为渔业种群必需经历过度捕捞和种群恢复阶段是剩余产量模型正确评估种群资源所需的渔业条件。 - The schnute model work well in full explored stocks such as scenario 1 , 3 , 4 and 5 , especially in low biomass stocks such as scenario 3 , but not suitable to the under explored stocks such as scenario 2 . the w - h model generally performed well in all kind of scenarios especially in scenario 1 , 4 , and 5 . in the swordfish , xiphias gladius , fishery , estimation of w - h model and d - fox model produced msy about 14000 ton , very near the result of prager in 1996
四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差； schnute模型在充分捕捞的渔业如渔业1 、 3 、 4 、 5 、尤其是在低生物量的渔业3中评估效果较好，但不适合评估未充分捕捞的渔业，如渔业2 ； walters - hilborn模型( w - h模型)适用于各种渔业，尤其是渔业1 、 4 、 5 ；在过度捕捞渔业中如渔业3 、 4 ，模型对参数q的估计较其它参数接近真值；在北大西洋箭鱼( xiphiasgladius )渔业的评估中， w - h模型和d - fox模型对msy的估计约为14000吨，接近于prager ( 1996 )的结果。
