The striking of single base propellant ( SBP ) grain on bullet bottom at high speed was simulated by experiment. 实验模拟了单基火药与弹底的高速撞击,运用泰勒理论计算了单基火药的动态屈服应力。
Study on the Height of High Plastic Clay at the Bottom of High Core Rockfill Dam 高心墙堆石坝心墙底部高塑性粘土厚度研究
The zone of paralleling bottom with high impedance and Lame parameter indicates the gas-hydrate layer, and the area with low impedance and Possion's ratio trapped by gas-hydrate layer below it symbolizes the accumulation of free gas. 认为波阻抗剖面和拉梅系数剖面上的近似平行于海底的高值带指示水合物层,且水合物层下伏所圈闭的低泊松比和低纵波波阻抗区域指示游离气的存在;
Reflection Loss and Phase of sea bottom with high sound velocity 高声速海底的反射损失和相移
Conclusion As to cell culture plate and enzyme label plate, both have same diameter, flat bottom and high transparency, therefore they can be used as the special vessel for the upside-down microscopy analyzing system of urine sediment. 结论孔底直径一致、底面平整且透光性好的细胞培养板和酶标板都可以作为尿沉渣倒置显微镜分析系统的专用尿沉淀板。
