Good correlations were found between the computed phytoplankton absorption coefficient and the measured value,with the determination coefficients (r2) being higher than 0.97 and slopes being around 1.0;and the RMSE values could be controlled within 17% over the main absorption wavebands such as 443,490 and 683 nm.

基于这种光谱变化规律本文建立了ap分解模型，并采用2005年同一海区实测数据进行验证，发现模型计算光谱与实测数据有较好的相似性，在主要的吸收波段如443，490和683 nm处的平均相对偏差值在17％以内，两者之间线性关系拟合的决定系数(R2)均在0.97以上，斜率接近于1.0。

Amount of total phenolic compounds, total flavones and DPPH scavenging activity for different kinds of vinegars were compared. The results indicate that (1) DPPH scavenging activity of different kinds of vinegars has a positive correlation with amount of total phenolic compounds, total flavones, the correlation coefficients were 0.9523 and 0.8691, respectively,(2) the higher content of phenolic compounds and flavones in Zhenjiang aromatic vinegar respond for its higher scavenging activity.

对不同品种食醋总酚含量、总黄酮含量、DPPH自由基清除活性的比较分析表明：(1)不同品种食醋自由基清除活性与醋中的总酚含量、总黄酮含量存在正相关性，相关系数分别为0.9523、0.8691；(2)镇江香醋中由于总酚含量、总黄酮含量较高因而自由基清除作用较强。

Meanwhile a new method to compute the vignetting coefficients has been given.

文章同时给出了计算渐晕系数的新方法。

However, the continued wavefields in traditional one-way wave equation migration are not the downgoing or upgoing components of the acoustic pressure wavefields. The amplitudes on the migrated sections still disagree with the reflection coefficients even if the dynamic imaging condition is applied.

不过，传统单程波动方程偏移的延拓波场并不是全波场的上、下行声压分量，即使采用常规的动力学成像条件，得到的成像振幅与声压反射系数之间也没有直接联系。
