查询词典 average density

The effects of air density,the solution's viscosity,the surface tension and density on optimum vibration frequency were analyzed.

分析了空气密度、胶液粘度、胶液表面张力和胶液密度对最优振动频率的影响。

Air density's effect is very little, however, optimum vibration frequency decreases with the solution's viscosity increasing, and increases with the solution's surface tension and the solution's density increasing.

According to technical staff on-site observation and investigation, resulting in a large area rotten seaweed seedling disease and the main obstacles to growth are as follows: by the autumn of high temperatures and earlier typhoon, the local ecological environment of the sea change in the short term; area of stocking density is too large, artificial breeding raft density plane, resulting in poor water exchange.

根据技术人员对现场的观察和调查，造成紫菜大面积烂苗症和生长障碍的主要原因有：受秋季高温天气及前段时间台风影响，局部海域生态环境短期内发生变化；海区养殖密度过大，养殖筏架人为设置密度过高，导致海水交换不畅。

In the Eogene and Neogene, Qaidam Basin experienced the multiphase tectonic movement; the paleoclimate evolved from warm-humid to arid; the water in the basin was gradually salinized; the depocenter migrated from west to east. The master factors and developmental characters of lithologic hydrocarbon reservoirs have their own particularity. Taking the fine exploration zones of the southwest hydrocarbon-rich depression in Qaidam as the key point, with the analysis of source-rock distribution, sedimentary evolution and sedimentary system distribution, the author proposes that the density difference increases after the fluvial water enters, then clam and bar sand bodies are formed easily due to density flow. Highstand system tract and transgressive system tract below the maximum flooding surface are the main exploration areas of lithologic reservoir.

柴达木盆地古近纪－新近纪经历了多期构造运动，古气候由温湿向干旱演变、湖盆逐渐咸化、沉积中心由西向东迁移的演化过程，地层岩性油气藏的主控因素和发育特征有其特殊规律，以柴达木盆地柴西南富油气凹陷精细勘探区带为重点，通过分析烃源岩展布、沉积演化和主要沉积体系展布，提出咸化湖盆在河流入湖后因密度差较大，易形成密度流等成因的各类滩坝砂体，最大湖泛面之下的高位体系域、湖侵体系域是地层岩性油气藏的主要勘探领域。
