查询词典 submergence

To these two types of BFP, the new schemes of towing and submergence were put forward: Type A BFP, added buoyancy with detachable cone-shaped pontoons, can be towed directly, and the self-ballast mooring submergence method can be applied into its submergence process. Type B BFP can be towed with the tied pontoons, and the submergence method is davit launch.

With the case study on Wanzhou in the three-gorges reservoir area, it had been studied and analyzed that the potentialities of exploitation and use on land and ecological safety by established land use database, and it had been revealed that serious loss of water and erosion of soil, ecological environment fragility, the water conservancy project submergence a large amount of land, arrannements of the numerous immigrations need a large amount of land, contradictory remarkableness among human and land, and the latent crisis by extensive management land were main crises and questions of the land use.

利用建立的土地利用现状数据库，以三峡库区最大淹没区万州为研究对象，对库区土地开发利用潜力及生态安全性进行了分析和研究。揭示了库区土地资源利用中存在的主要危机是水土流失严重、生态环境脆弱，三峡工程淹没土地多、移民迁建占地比重大、人地矛盾加剧及粗放经营土地带来的安全隐患等问题。

Objective To determine the content of blood strontium for diagnosis of deathful causes of drowning and postmortem submergence. Methods The content of Sr content in the water sample of Nan Du River on Hainan Province, and in the left heart's blood sample of rabbits died of drowning, postmortem submergence were determined with ICP-XSP. The results were compared with that the controls.

目的 研究动物溺水死后不同时间血锶的变化方法以高频电感偶合等离子体光谱分析仪检测外样水体中锶离子含量，并分别测定家兔溺死与死后入水的左心血的锶含量。

Total submergence largely decreased biomass production and growth in length,with less effect on shoot numbers.Increased elongation of the growing internodes of up to 140% is caused by submergence.Nutrient such as N,P,K do significantly affect on growth.No mater lack of any element will decrease the biomass,the result same as the oligotrophic conditions.But lack of phosphorus is the worst mater.

而淹没式淹水可能使生物量降低，但是植株的高度有所增加，因为淹水可以使芦苇的节间高度提高140％；对根茎的数量没有很明显的影响。N、P、K等营养元素对芦苇生长也具有重要的作用，无论缺少哪一种对芦苇生长都不利，跟完全贫营养状态没有明显的区别，但是缺P时芦苇生长是最差的。
