This document describes structure of buoyant material about large hollow sphere that made of superlight compound material ( This material is used at ROV within 1000 meters) Under safeguard for compressive strengh cause the density of buoyant material is minimum and moisture absorption rate fits requirement. 本文探讨了超轻质复合材料大空心球的浮力材料结构(此材料适用于1000m以内无人潜器上使用)和在保证抗压强度条件下,使浮力材料的密度最小、吸水率符合要求的设计方法。
It's buoyant density is 1. 2g/ ml which is consistent with that of HBsAg in the plasma of patients. 表达产物的浮力密度为1.2g/ml,与病人血清的HBsAg一致。
An integral model of buoyant jets is given in this paper. The profiles for velocity density and concentration difference are assumed to be Gaussian distribution, and the relations of the entrainment rate with local densimetric Froude number and cross velocity are derived for closing the governing equations. 给出了基于积分方法的一种倾斜浮力射流的数学模型,且流速、密度和浓度差剖面假定为高斯分布,并导出了用来封闭该数学模型的较为完全的掺入率公式。
The buoyant density of SRV was determined to be 1.36& 1.40g/ cm~ 3 in CsCl density gradient. 在氯化铯(CsCl)中的浮密度为1.36&1.40g/cm~3。
Finally, the proposed anisotropic buoyant turbulence model is applied to study turbulent density flows with combined temperature and salinity discharging into a tank with a slope bottom. According to the characteristics of thermal stratified flows, the explicit algebraic Reynolds stress model is derived; 最后,利用导出的浮力紊流模型研究了因温度和盐度的组合作用引起的浮力流动特征。根据湍浮力流动的特点,求出显式的应力代数湍流模式。
