为探究活性染料在非水介质无盐少水染色体系中的染色性能及染色动力学,文章以不同质量分数的活性黄145染料和硅氧烷组成无盐少水染色体系,对棉织物进行染色,对准一级动力学模型和准二级动力学模型进行分析,且与传统水浴染色效果进行对比。结果表明,在相同质量分数下,无盐少水染色体系染色性能较传统水浴更好,其中固色率及K/S值差异随着染料质量分数的增加而增大。活性黄145在两个染色体系中的染色动力学可以用准二级动力学模型来描述,相较于传统水浴体系,无盐少水染色体系具有更高的染料最终吸附量和更小的半染时间。随着染料质量分数的增大,染料最终吸收量的差距逐渐提高,半染时间逐渐缩短。为活性染料在非水介质无盐少水染色体系中的染色实践提供了理论指导。

The local solids holdup and local particle velocity in a Countercurrent Liquid-upward and Solids-downward Fluidized Bed(CCLSFB)were investigated in details using optical fiber probes with two different models in a Plexiglas column of 1.5 m in height and 7.0 cm in inner diameter.A new flow regime map including fluidized bed,transition,and flooding regimes was *** axial solids holdup distribution is almost uniform at low liquid velocity and/or solids flowrate and becomes less uniform with higher solids holdup at the top of the column after the operating liquid velocity is reaching the flooding *** radial solids holdup profile is also nearly flat with a slightly lower solids holdup in the near-wall region at low liquid velocity and solids flowrate but becomes nonuniform as the operating liquid velocity approaches the flooding *** equations were also proposed to correlate radial local solids *** descending particle velocity in CCLSFB increases with the decrease of the liquid velocity and the increase of the solids flowrate.A generally uniform particle velocity distribution was found in the axial direction,as well as in the radial direction except for a small decrease near the *** results on the local solids flow structure would provide basic information and theoretical supports for the design and industrial application of CCLSFB.

为深入研究煤炭开采过程中顶板结构面倾角对煤岩力学特性的影响,通过自主研发的地声过程模拟试验系统,开展不同结构面倾角条件下组合煤岩真三轴加卸载试验,并利用声发射探测系统进行监测。研究结果表明:随着结构面倾角的增大,试样的破坏强度逐步下降,裂隙发展也逐渐减弱,其破坏形态从张拉剪切破坏逐渐向剪切破坏转变,直至倾角达到40°时,试样整体发生滑移破坏;在卸载破坏前,倾角<30°的试样发生充分的塑性变形,其承载力得到充分发挥,而倾角≥30°的试样达到临界破坏极限时迅速破坏,出现部分或完全滑移破坏;声发射信号集中于卸载破坏阶段,试样的结构面倾角越大,声发射累计计数越少,当倾角达到40°时发生滑移破坏,最大振铃计数大幅下降,对其累计计数略有影响。研究成果可为深入认识顶板结构面倾角引起的卸载破坏机制及矿山安全开采提供参考。
