摘要：将绿豆芽生产中"烫豆"工艺的副产物加工成绿豆衣清爽饮料,依据绿豆衣中叶绿素的保护机理对绿豆浸提的护色工艺进行改进,在单因素实验基础上对护色剂进行复配,采用正交实验设计方法确定最佳护色剂配比,提出了绿豆浸提的最佳工艺为:浸提初始温度80℃,浸提时间20min,护色剂(柠檬酸钠0.20%、异VC钠0.016%、三聚磷酸钠0.05%),pH7.76。浸提液经高温高压(121℃,20min)杀菌后仍能保持绿豆自然的黄绿色泽。浸提和护色工艺对绿豆籽粒的种子活力影响很小,仍可进行绿豆芽的加工生产。

摘要：石油勘探中钻井液的混合效果直接影响钻井的速度和钻探工具的使用寿命。为有效提高钻井液的质量,对钻井液固控仓的搅拌系统进行优化设计。利用数值模拟软件对布置多台搅拌器的方形大固控仓内部流场和安装单台搅拌器并增加挡板的方形小固控仓内部流场进行模拟分析,通过设置多相流模型和湍流模型得到搅拌流场的速率分布、速度矢量分布及相同时间段内固相的浓度分布。结果表明,大固控仓内相邻搅拌器转向相反时可避免搅拌器之间的流动干扰,形成对称的较大的上下旋流,从而提高混合效果;在小固控仓的搅拌器四周布置挡板,可有效扩大搅拌流场的径向旋流区域,减少死角搅拌盲区的固相沉积,扩大轴向旋转区域,形成较大的上下翻转流动,有利于固液混合。模拟优化结果可为改善钻井液固控搅拌系统固液混合效果提供重要的参考依据。

摘要：在激光驱动的惯性约束核聚变的快点火方案中,需要将集束拍瓦皮秒激光精准引导至数十微米的金锥锥底上,并且瞄靶过程需要避免对冷冻靶预热。鉴于此,本课题组设计了一种集束皮秒拍瓦激光靶瞄准系统,使入射激光和对靶成像分离,从而实现非激光直接辐照下的近距离高精度束靶耦合。设计了识别焦斑与靶位置的程序,以减小人工识别误差,提高效率。搭建离线瞄准平台并开展了验证实验,该系统在5 mm×5 mm视场范围内的靶分辨率优于90.5 lp/mm(11.04μm),重复实验的平均束靶耦合精度为4.32μm。进一步使用Zemax软件优化成像系统,优化后系统在10 mm×10 mm视场范围内的分辨率优于5μm。此系统为惯性约束核聚变的皮秒集束激光束靶耦合提供了高精度的解决方案。
