estimated yield 中文意思是什麼
estimated yield
解釋
估計產量-
Using these data, we estimated cotton planting farmers " pesticides application equation and damage control production function, calculated the impact of bt cotton on pesticides use and cotton yield, and compared the poisonging probability due to pesticides application between bt cotton and non - bt cotton planting farmers. using bt cotton adoption area and the above results, this paper calculates the impacts of bt cotton on pesticides application, cotton production and poison cases all over china since the beginning of its adoption in china in 1997. the results demonstrate that the adoption of bt cotton reduced pesticides use approximatly 35kg per ha ; this is equivalent to 875 yuan of cost reduction
利用這些數據我們估計了種植棉花（包括轉基因抗蟲棉和非抗蟲棉）農產農藥施用方程和棉花損失控制生產函數（ damagecontrolproductionfunction ） ，估計了抗蟲棉對棉花農藥使用和棉花產量的影響，同時比較了種植bt棉與非bt棉農產在使用農藥過程中中毒概率的差異，在此基礎上，利用抗蟲棉在全國各地的推廣面積以及以上的分析結果，測算了1997年以來抗蟲棉的推廣對全國棉花農藥使用量、棉花產量以及棉農施農藥中毒事件的影響，並對其經濟影響的不同受益者作了分析分解。 -
Second, from tang dynasty to early song dynasty, the category of the ma - crops contains huangma （ 黃麻 ） ， youma （ 油 麻 ） ， ma - seed （ 麻子 ） ， and ma - oil （ 麻油 ）. the area of them was about one third of all the cultivated land, and the per mu yield was estimated 15 jin （ 唐 斤 ）
第二，唐五代宋初敦煌的麻植業品種包括：黃麻（今胡麻） 、油麻（今芝麻） 、大麻（苴麻和?麻） ，植麻面積約占當時總耕地的1 / 3 ，畝產量約15唐斤。 -
Judgement of estimated yield
預計產量鑒定 -
The results from this paper show that defeats in cast - in - situ concrete structure yield with the possion distribution, the parameters are estimated. in the last, the causes of quality problems are analized and the suggestions are gived as well
通過現場實際調查，發現混凝土現澆結構工程的外觀質量缺陷服從possion分佈，參數值為0 . 2左右；最後對混凝土結構的外觀質量改進提出了建議。 -
Firstly, this dissertation estimated the size of carbon source ; sink and net carbon sink of farmland ecosystems in china costal regions ( including ten provinces ) with statistic data from 1981 to 2001, which include data of crop yield and agricultural consumptions. then analyzed the temporal - spatial differences of carbon source, sink and net carbon sink of china costal farmland ecosystems. secondly, estimated npp ( net primary productivity ) of farmland ecosystems in china costal regions with per month noaa - avhrr ndvi ( normalized difference vegetation index ) data and estimation model
本文首先運用1981 - 2001年的統計資料（作物產量和各種途徑的農業投入數據） ，對沿海十省區農田生態系統碳源匯及凈碳匯進行了估算，並分析了其時空差異；然後運用1998年逐月ndvi數據通過建模對沿海地區農田生態系統npp進行了估算，並分析了npp分佈與農田生態系統碳吸收的相關性；最後通過對農田生態系統碳源匯的影響因素分析，提出了不同的農田生態系統碳增匯減排技術。 -
It was estimated that the yield of the e2 fusion protein in culture supernatant of recombinant p. pastoris could be reached 0. 34g / l. the optimal expression conditions were explored for the ph, aeration rate, final concentration of methanol and kinds of growth media. we conclude that the higher quantity of e2 protein can be gained at ph4. 0 - 6. 0, 1 % methanol as the final concentration, mm growth media and high aeration rate
通過對表達條件如ph值、通氣量、誘導甲醇終濃度、培養基的選擇等條件的探索，可確定豬瘟病毒hl - ly株e2基因表達的理想條件為：最適ph值在4 . 0 6 . 0之間，最適培養基為mm培養基，最佳誘導的甲醇終濃度為1 ，加大通氣量時表達量較好。 -
