Template Structures By far the most common type of fixed offshore structure in existence today is the template, or substructure that extends from the seafloor to above the water surface and a prefabricated steel deck located atop the substructure. The deck is supported by pipe piles driven through the legs of the substructure into the seafloor. These piles not

The basis for ship equilibrium Consider a ship floating upright on the surface of motionless water. In order to be at rest or in equilibrium, there must be no unbalanced forces or moments acting on it. There are two forces that maintain this equilibrium (1) the force of gravity, and (2) the force of buoyancy

“水是生命之命脉”。 土壤水分是土壤最为重要的组成部分,它在土壤形成 土壤的演化过程中起到极为重要作用水是土壤中一系列 过程进行得媒介。土壤水是土壤微生物、植物的最主要的 水源。土壤水分状况是土壤肥力的最重要的因素之一 农谚说:有收无收在于水,收多收少在于肥。 我国是水资源贫乏的国家,北方属于缺水的旱地农业 占52%左右。北方主要主要是发展节水农业(土壤保水) 南方季节性缺水和洪涝灾害频繁发生,主要问题需要进行 排水除涝

有些种藻类在小水体和浅水湖泊中常大量 繁殖,使水体呈现色彩,这一现象称为“水 华”( water bloom)。有些藻类在海水中大量繁 殖,形成“赤潮”( red tide)。藻类在水体中 暴发性生长,对水域生态系统造成了很大的影 响,也是目前对藻类生态学研究方面最热点的 课题之一
