循环流化床灰与煤粉炉粉煤灰在物理特性及力学性能上有较大差别,阻碍了其大规模的利用,为解决循环流化床灰路基填料的合理利用问题,采用激光粒度检测仪、XRD、SEM及室内试验测试手段,对循环流化床灰的颗粒特征、物相组成、微观结构及路用力学性能进行了研究。研究结果表明:循环流化床灰的粒度主要分布在10~80μm,矿物成分主要为石英、硫酸钙等,没有莫来石;微观结构上,循环流化床灰颗粒表面凸凹不平,呈现不规则、扁平状的疏松形态,能形成较多的吸水孔隙,致使循环流化床灰在击实试验中需水量较大,最优含水量达38.6%;CBR值、回弹模量及抗剪强度均与压实度呈现较好的线性增长关系,随着压实度增大,CBR值、回弹模量及抗剪强度均会增长,但CBR值的增长幅度更大;当压实度达到92%后,循环流化床灰的抗剪强度随压实度的增加强度增长不显著。

为探明滴灌施肥频率对烤烟生长、氮肥利用及烟叶产质量的影响,2018-2019年通过田间试验,以不施肥空白(CK)和当地常规处理(CF,即肥料干施+滴灌)为对照,研究低频滴灌施肥(DF1,即养分管理期1次滴灌施肥)、中频滴灌施肥(DF2,即养分管理期连续2天每天1次滴灌施肥)和高频滴灌施肥(DF3,即养分管理期连续3天每天1次滴灌施肥)对烤烟农艺性状、根系发育形态、氮肥累积量和利用效率及烟叶产质量的影响。结果表明,与CF相比,各滴灌施肥处理烟叶产量无显著差异(P<0.05),氮肥利用率有不同程度提高,烟株发育状况则因滴灌施肥频率而异。与DF1和DF2相比,DF3烟株旺长期叶面积系数分别增加了7.3%~33.3%和1.6%~28.7%,根系体积分别增加了3.9%~46.6%和21.2%~40.5%,氮素利用率分别提高了39.0%~95.0%和21.5%~34.3%,烟叶烟碱含量分别增加了17.5%~28.5%和12.5%~20.0%。与中频滴灌施肥和低频滴灌施肥相比,高频滴灌施肥有利于促进烟株生长和根系形态发育,提高氮肥利用效率和烟叶品质质量,是有效协同氮肥高效利用和烟叶产质量的滴灌施肥措施。

针对经典联合变换相关器互相关峰能量分散以及输入图像大小和相对位置受到限制的缺陷,提出了基于马赫-曾德尔干涉仪的单相关峰联合变换相关技术。目标图像和参考图像通过马赫-曾德尔干涉仪的两臂无相对位移输入,实现了互相关峰重叠位于探测器中心,缓解了输入图像的大小和相对位置与变换透镜孔径和探测器接收面积之间的矛盾;采用功率谱相减技术,消除了零级自相关峰对互相关峰的影响,增强了衍射效率。理论分析和实验结果表明,该方法不仅能获得高强度的单相关峰,使抗噪声能力是CJTC的6倍,从而大大增强了识别能力,而且充分利用了输入面空间带宽和探测器的效率,降低了系统成本,特别适合于弱信号噪声环境和大尺寸图像的识别。
