solids holdup meaning in English
固体粒子停留时间
Examples
- The solids holdup is lower in the center than in the wall region at the radial positions , and the solids holdup is higher in the lower section than in the upper section of the riser
在径向分布上，颗粒浓度呈现中心稀，边壁浓的状态。在轴向上，颗粒浓度呈现上稀下浓的分布。 - Hydrothermal modification temperature , hydrothermal modification time , concentration of aqueous cacl2 solution and solids holdup of mg ( oh ) 2 particles showed important effect on the morphology , crystalline structure and dispersion properties of the hydrothermal products
研究发现水热改性温度、水热改性时间、改性剂添加量和水热浆液固含均对水热产物的形貌和一次粒径有一定的影响。 - A hybrid method for prediction of solids holdup in gas - solid circulating fluidized bed is proposed based on chaos phase reconstruction and wavelet package as well as neural networks . experimental results show that the model provides good predictions and has promising applications
气一固循环流化床的颗粒浓度时间序列预测结果表明，小波、混沌和人工神经网络结合预测模型可有效地用于气固循环流化床局部颗粒浓度波动时间序列信号的短期预测。 - A solid - liquid fluidized bed has been designed and installed , which will be used in the heat exchanging and descale field . the experimental study for distributor design was carried out and the particles distribution in the tubes of the solid - liquid fluidized bed under different operating conditions was studied by using the ccd measure system . experimental results show that heterogeneous pores distributor which was arranged in the inlet chamber of the solid - liquid fluidized bed can improve the nonuniform distribution of particles in the pipe bundle under high flow rate . the nonuniform decreases by decreasing the mount of pore , but the solid holdup decreases too . the particles distribution is influenced by the position of the heterogeneous pores distributor
实验结果表明：在液固循环流化床进口段安装可调节高度的变孔径分布板，能在较高的流速下，较好的改善固体颗粒在管束中的不均匀分布；开孔率越小固体颗粒在管束中的分布越均匀，但管束中粒子的平均固含率也越小；分布板的安装高度对颗粒的分布有很大的影响，在实验范围内分布板的安装距离管束入口处越远，颗粒在管束中的分布越均匀。 - The denoising results about solids holdup and pressure fluctuation signals of gas - solids cfb riser indicate that wpa denoising method based on fractal theory can efficiently differentiate the noises from the solids holdup signals , and the denoised effect is much better than that by filter method based on the fourier transform
