浮游植物吸收系数
“浮游植物吸收系数”译为未确定词的双语例句
It is shown from the data analysis that the hyperbolic tangent function relation between phytoplankton absorption coefficient a φ(λ) and a φ(675) in the semianalytic algorithm is not likely to accord with the optical characters of seawater in the highly polluted Pearl River estuary area, so a simple quadratic function relation between a φ(λ) and a φ(443) is suggested. 原算法中建立的浮游植物吸收系数aφ(λ)与aφ(675)之间的双曲线正切函数关系式可能并不符合珠江口这一高污染河口区的光学性质,故给出了aφ(λ)与aφ(443)的简单二次函数关系式。 短句来源 Effects of size structure and pigment composition of algal population on phytoplankton absorption coefficients in the South China Sea 南海北部藻类粒级结构及色素成分对浮游植物吸收系数的影响 短句来源 Since the variations of size structure of algal population and the accessory pigments contributed differently to the variability in the phytoplankton specific absorption coefficients for estuary,coastal waters and open oceanic waters,it is suggested that in order to set up a more perfect bio-optical algorithm in the NSCS,the variations in the optical properties of phytoplankton caused by the pigment package effect and changes in the relative abundance of accessory pigments should be incorporated. 由于河口、近岸和外海水体藻类粒级结构和辅助色素成分对浮游植物吸收系数的贡献有明显的差异,在南海北部水体建立比较精确的生物光学模型时,需考虑藻类粒级结构及色素成分对浮游植物吸收系数的影响. 短句来源 相似匹配句对

The absorption coefficient of particulates in seawater can be partitioned into the absorption coefficients of non-algal particulates and phytoplankton. Using the quantitative filter technique (QFT), the absorption coefficient of particulates in seawater was determined. The coefficient of non-algal particulates is decreasing with the increase of wavelength, which can be described by exponential law. The spectral slope, S, is discrete in the Zhujiang River Mouth, but its average is similar to the reports of... 海水中总颗粒物的吸收系数可表达成非藻类颗粒物与浮游植物的吸收系数之和,利用可定量测量的滤膜技术(QFT)测定水体中颗粒物光谱吸收系数。非藻类颗粒物的吸收系数随着波长的增大而减小,可用指数衰减规律来描述;光谱斜率S较离散,但平均值与文献报道的一类水体S的平均值很接近;光谱截距ad0(λ0)随盐度增大而减小,二者有很好的线性关系。浮游植物的比吸收系数和叶绿素a浓度之间存在非线性关系,但是,比吸收系数与叶绿素a浓度之间的非线性关系同时还与波长有关,在叶绿素a的2个吸收峰443nm和670nm附近非线性关系特别明显,而在530—640nm之间两者的非线性关系则较弱。 文摘来源 Data from three cruises conducted in the Zhujiang River(ZR) Estuary,costal waters of Guangdong(CWGD) of China and north of the South China Sea(NSCS) were examined to access the relative importance of pigment composition and package effect in modifying the phytoplankton specific absorption coefficients.The three cruises differed widely in their phytoplankton assemblages with large cells dominating the ZR and CWGD cruises and small cells dominating the NSCS cruise.And therefore the package effect for the ZR a... 在珠江口、广东沿岸及南海北部三个航次生物-光学数据的基础上,研究了色素打包效应和色素成分的变化对浮游植物吸收系数的影响,结果表明,两种因素对吸收系数都有较大的贡献,但在不同的水体它们的影响程度各有不同.对网采浮游植物含量较高的珠江口和广东沿岸的水体而言,色素打包效应较强,对675 nm处比吸收系数的贡献平均分别为40%和20%;对微型浮游植物占主导地位的南海北部航次的水体,打包效应较弱,对675 nm处比吸收系数的影响平均仅为6%.采用多元线性回归的方法对吸收光谱进行分析,发现除叶绿素a之外的辅助色素对吸收系数的贡献主要表现在蓝绿光波段,三个航次440 nm波长处对总吸收的贡献平均分别为44%,43%和53%,其中对珠江口和广东沿岸航次的水体主要是光合类胡萝卜素的吸收贡献,而对南海北部航次的水体除了光合类胡萝卜素以外还要受到光保护类胡萝卜素的影响.由于河口、近岸和外海水体藻类粒级结构和辅助色素成分对浮游植物吸收系数的贡献有明显的差异,在南海北部水体建立比较精确的生物光学模型时,需... 文摘来源 >=In this paper, the absorption coefficients of particulates(including phytoplankton and nonpigmental particles) and colored dissolved organic matter(CDOM) measured in the Pearl River estuary area are used to make an amendment to the empirical equation of MODIS semianalytic algorithm. It is shown from the data analysis that the hyperbolic tangent function relation between phytoplankton absorption coefficient a φ(λ) and a φ(675) in the semianalytic algorithm is not likely to accord with the optical cha... 利用珠江口2002年11月颗粒物质(包括浮游植物与非色素颗粒)及有色溶解有机物质(CDOM)吸收系数的测量,尝试修正MODIS半分析算法经验方程。原算法中建立的浮游植物吸收系数aφ(λ)与aφ(675)之间的双曲线正切函数关系式可能并不符合珠江口这一高污染河口区的光学性质,故给出了aφ(λ)与aφ(443)的简单二次函数关系式。非色素颗粒吸收系数(ad)总体上远大于CDOM吸收系数(ag),所以,没有分离ad 和ag 而直接导出ag 并不切实可行;建议参数S取值0.012 nm-1。当然实用的珠江口MODIS半分析算法还需要进一步的调试与优化。 文摘来源
