Arguably this is the broadest range of stand-up paddle boards on the market with a unique balance of SUP-specific volume distribution and rocker. SUP可说是目前市场上板体最宽的立式划板,并于容量分布和弧形线条两方面取得独特的平衡。
Based on the principle of mass balance, a finite volume method is proposed to solve the equation and then compares it with experimental data. 以质量守恒为基础,本文提出了求解该方程的有限体积法。
In this paper, the quasi-steady quasi-three-dimensional heat and mass transfer model in the tail water tunnel was found on the principle of thermal balance by using finite cell to control volume. 本文以微元控制容积的热质平衡原理为基础,建立了准稳态准三维的尾水洞通风换热传质模型。
The results show that the stiffness is dependent not only on the pressure and volume at static balance, but also on the change rates of efficient area and volume. 结果表明:空气弹簧的刚度不仅与其静平衡位置时的压力和容积有关,还与其有效面积变化率和体积变化率有关。
On the 2nd postoperative day, the negative fluid balance occurred in 107 cases, and 147 cases on the 3rd postoperative day, the average volume of the negative fluid balance being ( 1490.84 ± 297.43 ) mL. 术后第2天107例出现负平衡,第3天147例,负平衡量(OBV)达(1490.84±297.43)mL。
