分析化学是发展和应用各种方法、仪 器和策略,以获得有关物质在空间 和时间方面组成和性质的一门科学, 是表征和量测的科学。 原子量的准确测定、工农业生产的发 展、生态环境的保护、生命过程的 控制等都离不开分析化学

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

Section 1 Soil three phases Constitution Soil density and bulk density (一) Soil density( or Particle density) Soil density is the density of the solid soil particles only; the measurement does not include water weight or pore (air)space. The dominant soil minerals-quartz, feldspars micas, and clay minerals-
