煤炭装载冲击是露天煤矿主要的产尘环节之一,尤其在自然风流的作用下容易造成大面积的粉尘污染。针对内蒙古地区露天煤矿地域气象风力强劲、装车冲击粉尘浓度高、粉尘扩散污染严重等问题,采用Realizableκ-ε湍流模型,结合数值模拟分析不同风速扰动下装载冲击产尘运移规律,探究抑尘运移方法及其防治粉尘污染的作用效果,结合内蒙古白音华三号露天煤矿装车站现场,设计优化阻尘技术并进行现场应用与效果分析。研究结果表明:流经装车涵洞的过堂风、背风面形成的涡旋风流是促使下风侧粉尘颗粒运移的主要原因;随着风速的增大,装车站风流的不均匀性不断加剧,粉尘颗粒在风流的夹带作用下向下风侧区域扩散;粉尘扩散污染路径装设抑尘网可实现对粉尘运移的有效阻隔,且随着抑尘网高度的增加,装车站下风侧区域内的风速值出现显著降低,并在装车涵洞出口处形成一条风速值分布较为均匀的低速带,进而降低了粉尘颗粒的逃逸速度,有效控制了粉尘的扩散范围;此外,抑尘网安装高度对于风流场与粉尘运移的影响存在阈值,基于模拟研究结果,优选网高为7 m的防风抑尘网进行现场应用。现场粉尘浓度测定结果表明:抑尘网内外粉尘降低效率达到82.51%以上,有效降低了装车站粉尘扩散范围,对矿区周边的环境保护具有重要意义。

To achieve better control of the formation of silver sulfide （Ag2S） nanoparticles, ultrasmall Ag nanoclusters protected by thiolate ligands （Ag44（SR）30 and Agla（GSH）9） are used as precursors, which, via delicate chemistry, can be readily converted to monodisperse Ag2S nanoparticles with controllable sizes （4-16 nm） and switchable solvent affinity （between aqueous and organic solvents）. This new synthetic protocol makes use of the atomic monodispersity and rich surface chemistry of Ag nanoclusters and a novel two-phase protocol design, which results in a well-controlled reaction environment for the formation of Ag2S nanopartides.

High-resolution time-to-digital converter(TDC) finds major applications in light detection and rang ing(lidar) systems as one of the high precision time measuring techniques. In this work, a high-resolution TDC i designed and implemented on a Xilinx FPGA board. For precision time measurements, the proposed TDC uses an in ternal tapped delay chain written in Verilog. The TDC circuit measurement errors are examined and calibrated fol lowing several principles of error reduction techniques to meet the specific demand for the high-precision lidar range Experiments have shown that the suggested calibration TDC has higher performance, achieving sub 35 ps resolution The design is fully customizable and implemented as a set of separate IP cores. This allows for easy implementation and meets the requirements of the present-day pulse lidar systems.
