In the air samples ,di(2-ethylhexy) phthalate,di-n-butyl phthalate and dioctyl phthalate were included,while diethyl phthalate,di(2-ethylhexy) phthalate,dipropyl phthalate,butyl benzyl phthalate,dioctyl phtha...

大气环境样品中邻苯二甲酸酯类化合物的预处理主要采用的是索氏提取、溶液提取和填充柱分离；水环境样品中采用的前处理技术较多，但大多数都是萃取技术；底质和生物试样目前用的较多是微波萃取、超声波萃取和索氏提取。

This dissertation, based on (1) field investigations and observation along Jiangsu coastal environment (including: sea bottom and tidal flat sediment sampling, water depth, salinity, current velocity and direction, core drilling and so on);(2) integrative laboratory analyses of micropalaeontology, sedimentology and computer-processed mathematical statistics on over 300 samples and about 100 thousand foraminifera tests, try to find and formulize the relations between foraminiferal thanatocoenose and environment.

本文的写作基础是：通过野外进行的海岸环境调查和测量（主要调查项目有：水深、盐度，流速、流向、含沙量、底质采样、浅地层地震剖面仪探测、潮滩钻孔取样、潮滩探槽的挖掘与沉积物取样、观测等等）取得了环境参数和大量样品；在实验室运用微体古生物学、沉积学、数理统计与计算机分析相结合的方法，对所采集的现代表层沉积物和钻孔岩芯样品共计三百多个进行了分析研究，鉴定统计有孔虫标本十万余枚，研究有孔虫埋葬群特征与环境参数之间的定性-定量关系。

The phenomena of overproof of iron and manganese content in the reservoir water after heavy rainstorm in south areas is analyze d by taking one reservoir as a case based on studying the external pollution sources,groundwater,soil and sludge.

以福建省某水库为例，对南方地区暴雨后水库中铁锰超标现象从外污染源、地下水、土壤、底质多方面进行了分析，找出了该类型水库中铁、锰超标的原因，并提出建议。

The results show that water depth has a greater effect on the growth of Potamogeton malaianus than sediment type.

结果表明：(1)水深对马来眼子菜的影响比底质的影响大。

To investigate the sea water quality and sedimental envirenment,12 sampling points were made in the sea area of Tieshan port(109°30′￣109°36′ E,21°25′30"￣ 21°31′30" N).

为了解铁山港海域的海水水质与底质环境现状，在铁山港海域（109°30′～109°36′E，21°25′30&～21°31′30&N）设点12个。

The feed put in it and the waste matter and metabolites output of it have a series impacts on the sedimental environment.

主要污染影响因素包括有机质、化学制剂和营养盐等直接影响因素；溶解氧、硫化物、底质厚度增加等间接影响因素。

OCPs residue of samples was determined by gas chromatography with electron capture detector after pretreated by Soxhlet extraction.

采用索氏提取方法(Soxhlet Extraction， SE)和气相色谱法，分析底质中有机氯农药的残留量。

During the study period, we found that plants were present only in natural creek banks, but not altered ones. Comparisons between natural banks without plants and altered banks revealed no significant difference in both shrimp abundance and distribution. However, there was significant difference in shrimp abundance when natural banks with plants and altered banks were compared, suggesting that construction might have negative effects on plants and, in turm, on shrimp abudance. Comparisons between reproductive and non-reproductive season yielded significant results in both shrimp abundance and distribution, which resulted from the recruitment of juveniles to local populations.

在实验期间，自然河段有水蕴草而整治河段没有水蕴草的存在，比较无水蕴草的自然河段与整治河段，发现无论是数量或出现率都没有显著差异，然而，在有水蕴草存在的自然河段之多齿新米虾数量与出现率则较整治河段高，显示哈盆溪可能因为整治工程影响了底质的型态，导致水蕴草不易生长，进而影响多齿新米虾的数量及出现率；在季节方面，结果显示，不同季节在数量和出现率上都有显著差异，而此差异是因为幼虾在生殖季大量加入族群所致。

Basic characteristics and prevailing genetic models of Chondrites have been introduced and commented. Unusu-al features of Chondrites from the Lower-Middle Ordovi-cian transition have been reported in the west-central Utah, USA. They include that tiny Chondrites -were cut by other trace fossils associated with them and formed in softground, and that Chondrites were the earliest or shallowest tiering in the complex ichnofabrics.

介绍和评述Chondrites的基本特征和流行的成因解释，记述最近发现于美国犹他州中西部北美下-中奥陶统之交层型剖面上的Chondrites遗迹组构的不寻常特征和属性：细小的Chondrites被所有与之共生的遗迹化石交切，形成于水与沉积物界面附近缺氧的早期软底质中，Chondrites是形成最早和最浅的遗迹阶层。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
