表觀消化率 的英文怎麼說
中文拼音 [biǎoguānxiāohuàlǜ]
表觀消化率
英文
apparent digestibility-
And understanding and studying the spectral features and variation rules of geo - targets in the experimental area, raising that it is the basis of geo - targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo - targets, realizing that in a great extent spectral - integrated - form - based classification method can remove the phenomenon of " different spectrum with same objects " resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo - target with similar spectral forms and much different values of whole reflection ratio. it is suggested that " red edge " range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel - based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. the remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed
研究結果如下:首先針對荒漠化地區的地物特徵,對高光譜數據不同波段的數據質量、波段組合進行了評價,提出了適用於荒漠化監測的基本波段選擇集;初步了解和掌握了研究地區的地物光譜特性及變異規律,進一步明確了掌握地物光譜特徵和變異規律是用成像光譜儀數據提取地物信息的基礎;發現了基於光譜整體形狀的分類方法在很大程度上能夠消除由於傳感器、地物目標觀測方向之間的角度變化引起的反射率曲線整體平移的「同物異譜」現象,對于譜形相似而整體反射率的值相差較大的兩類地物,通過引入均值和方差圖像參與分類得到解決;研究還表明在植被「紅邊」范圍內的波段是進行荒漠化監測的主要特徵波段,這些波段與植被生物量和蓋度都有密切的關系,是開展精細植被分類研究和植被定量反演的重要基礎;像元的導數光譜分析可以消除土壤背景的影響,是進行植被生物量和蓋度定量反演的有力工具;建立了荒漠化監測主要評價因子的定量反演模型,並分析了模型的適用性。Apparent digestibility coefficients of various feed ingredients for japanese sea bass lateolabrax japonicus

用兩種糞便收集方法測定草魚對九種飼料原料的表觀消化率To answer the question " why to reform ", the paper explores the cause in terms of demand, efficiency, competition, and environment, and proposes that demand for consumption is the outset of the distribution channel as well as the end of the channel. any change in quantity and structure of consumer demand will result in corresponding changes in the structure and behavior of the distribution channel. as it can reflect the function and utility of the specified system in a specific period, efficiency has become the driving force to initiate the reform in the distribution channel
消費需求在數量上與結構上的每一次改變,都會拉動流通渠道結構與行為的相應變革;效率作為特定歷史條件下特定系統的功能與效能反映,其經濟性、客觀性及發展性特徵成為流通渠道變革的驅動力;競爭是市場經濟的基本現象,它在流通渠道中表現為部門競爭及部門間競爭,兩個方面競爭的共同作用必然導致流通渠道整體結構、數量、關系等一系列相應的變革;環境是流通渠道生存的空間,其從政治、經濟、人口、技術等方面對流通渠道形成制約,環境的變化刺激流通渠道產生相應的變革。Effect of dietary levels of kelp meal on the growth and digestibility of litopenaeus vannamei
