利用曲线拟合技术对其光谱的ν1-SO峰进行分峰，获得了不同湿度下ZnSO4微液滴中各组分的量化信息：高湿度时，液滴中主要包含自由的水合SO；随着湿度降低，自由SO逐渐向单齿、双齿接触离子对转化，并在湿度为66%和34%时分别达到其最大值；继续降低湿度，复杂的链状或网状接触离子对逐渐成为液滴中的主要成分。

Results Nine compounds from supercritical CO2 extraction were identified and the main constituents were pentadecane, ethyl pmethoxycinnamate and ethyl cinnamate. Twentyeight compounds from water distillation were identified and the main constituents were δ3carene, ethyl pmethoxycinnamate and ethyl cinnamate.

The environmental transport of POPs in Dagu Drainage River selected as a typical example is reasonedly investigated in this article. Characteristics of sediment from DDR in Tianjin are analyzed. The mean value of TOC in sediments is as high as 8%, which is in favor of sorption POPs. The particle sizes of both suspended sediment and bottom sediment are mensurated by Malven Mastersizer. Silt accounts for about 60% in mass, while clay is about 10%. Particles of sediments belong to fine granule. Suspended sediment and bottom sediment mensurated by XRD mainly consist of quartz and illite, both account for 75.5% and 62.2%, respectively. The conformation of suspended sediment is very similar to bottom sediment from SEM photo.

采集自天津大沽排污河的底泥样品进行了特征分析：全河段底泥TOC含量较高，平均值约为8%，利于吸附POPs；Malven Mastersizer激光粒度仪测定了大沽排污河悬浮物和沉积物的粒径分布，结果表明主要以粉砂为主，占60%左右，其次为黏土，占30%左右，大沽排污河底泥颗粒属于细颗粒；悬浮物样品和表层沉积物样品经X射线衍射分析表明，石英和伊利石是大沽排污河底泥悬浮物及沉积物矿物的主要成分，两者之和分别占75.5%和62.2%；环境扫描电子显微镜结果表明，河流底泥悬浮物和沉积物的形态没有本质差别。

Nothing special or flash there, just the grand Western tradition of spicing up lettuce with other ingredients, to make up for the fact that most lettuce tastes exactly like its primary content - water.

西方传统色拉很普通，没有肉，主角生菜主要靠配菜提味。因为生菜主要成分是水，所以它尝起来也跟水一样淡而无味。
