Furthermore, in order to improve the interpretation of the deltaic sedimentary record, e.g., to identify climate and environmental changes using the record, the various parameters derived from analyses of the cores should be standardized by evaluating the temporal changes caused by early diagenesis and decay, and by determining the rate of deltaic shoreline changes which control the relative position of the record within the deltaic sedimentary system.

此外，在长江三角洲沉积记录的分析方面，为了更好地提取气候、环境演化信息，应充分考虑沉积记录形成后所经历的自身变化（如成岩作用变化、分解和衰变等）和相对于岸线迁移的空间位置变化。

Morphological differences among two Eriocheir japonicus populations collected from Suifen River and Hepu River and two Eriocheir sinensis populations from Changjiang and Liaohe River were studied based on cluster analyzing and discriminal analyzing on 17 morphological characters , and the hybrids of Eriocheir sinensis× Eriocheir japonicus was also researched as an assistant subject.

选取合浦水系和绥芬河水系的日本绒螯蟹与长江水系和辽河水系的中华绒螯蟹4个绒螯蟹种群，以辽河水系绒螯蟹与绥芬河水系绒螯蟹杂交后代为辅助研究对象，对它们的17个外部形态特征分别进行聚类和判别分析。

The discriminal analyzing also separated samples from changjiang and the other four populations. The mean accurancy rate of discrimination of female crabs and male crab were 74.2% and 75.4％.

判别分析亦可将长江蟹与合浦蟹、辽河蟹、绥芬蟹和杂交蟹分开，雌蟹整体判别率为74.2%；雄蟹整体判别率为75.4％。

According to the unstable condition of the displaceable block and the breakage term of the stratified rock, this paper analyzed the stability of surrounding rock during the excavating process in different geological structures.

长江科学院监理公司，湖北武汉430030中文摘要：结合工程实例，基于块体的失稳条件和层状岩体的破坏条件，分析不同地质构造形态岩层下，隧洞开挖过程中围岩的稳定性。

Field experiments were conducted to examine integrated inhibition of allelopathic rice (Huakangcao 78), bensulfuron methyl application and water management on weeds in paddy field, with the purposes of attempting to reduce the dosage of herbicide applied in rice field and exploring new ways of weed management in rice production. The results showed that allelopathic rice could inhibit the germination and growth of barnyardgrass Echinochloa crusgalli L.

选用具有化感特性的水稻品系华抗草78和长江流域地区主栽的扬稻6号，通过田间试验研究水稻化感作用结合苄嘧磺隆使用及水层管理对水稻田杂草的抑制作用，旨在降低水稻田化学除草剂使用量，探索水稻生产中杂草治理的新途径。

The Lake area in Jianghan Plain is one of the most ecotypically fragile areas in Yangtse Valley, and here there are four main ecological problems: frequent flood, silt and sand that make the lake become a swamp, water pollution and eutrophication, and the schistosome.

江汉平原湖区是长江流域生态环境最脆弱的地区之一，洪涝灾害严重、泥沙淤积和沼泽化现象普遍、湖泊水体污染与富营养化问题突出、血吸虫未得到根治等是该区目前存在的主要生态环境问题。

The estuarine sediment distribution is closely related to the estuarine topography and submerged delta.

长江河口的沉积物分布是和河口地形及水下三角洲的发育密切相关的。

Most species of fish larvae and juveniles belonged to euryhaline fish.

与历史间期资料相比，经济性鱼在种类上和数量上都有所减少，低价值鱼类比例的增加成为调查区仔稚鱼资源结构的变动趋势，表明长江河口水域经济种类仔稚鱼资源已受到严重的威胁。

Most species of fish larvae and juveniles belonged to euryhaline fish.

与历史同期资料相比，经济性鱼类在种类上和数量上都有所减少，低价值鱼类比例的增加成为调查区仔稚鱼资源结构的变动趋势，表明长江河口水域经济种类仔稚鱼资源已受到严重的威胁。
