传统的近区地形改正方法无法保证在复杂地形条件下的地改计算精度,进而大大地限制了高精度重力测量在解决矿区深部找矿问题方面的潜力.基于此,本文介绍了一种基于三角网扣合的高精度近区地改算法来解决山区重力测量工作中的精度问题,该算法将近区地表划分成多个三角形,再分别计算出每个三角形对应的解析解值,最后累加得到高精度的重力地改值.该算法的最大优点是,方法本身不存在"理论上"的误差,误差仅来自于三角网与实际地形间的扣合程度,三角网的剖分越精细,计算精度则越高.算例分析表明,当三角网的剖分足够合理时,即使在一定的

海冰外缘线是一个描述北极海冰快速变化的重要指示参数,对近岸冰区航行保障和海冰灾害预警具有实际意义。本文首先基于形态学中的方法分别识别数据中的主体冰域、主体水域和碎冰区。其次利用可变图像闭运算方法将较大碎冰与主体冰区合并,最后再利用连通域方法提取海冰外缘线。该方法可适用于任何冰水二值数据集,包括海冰密集度产品数据、卫星图像、航拍图像以及其他冰水混合数据。本文基于AMSR-E海冰密集度数据,利用此方法

Short-lived climatically important atmospheric aerosols and trace gases such as ozone play major roles in global and regional climates,the chemistry of the atmosphere,and the biogeochemical cycling of
基于刘复刚和王建(2013)创建的行星会合指数(K),已经给出了太阳绕太阳系质心的运动轨迹,并得到其恒星周期为准22年.这一恒星周期是根据行星系统中按各自行星质量权重求得的23.77208年周期与通过图像获得的19.8585年行星会合周期的平均值得到的.因为各行星的周期都是恒星周期,故本文通过对K2函数求导方法得到的23.36886年周期也是恒星周期,它与23.77208年周期近似相等,这进一步证
