对普通PCA(principal component analysis)算法进行了改进,使之能用来检测点云模型中存在的平面反射对称性。算法的执行过程如下:首先,使用每个点元的面积作为权重,执行一次加权PCA确定一个近似的对称平面作为初始平面;然后,采用迭代的方法逐步调整上述的对称平面,使之趋向于真正的对称平面(主对称平面)。在每次迭代过程中,算法根据一个距离度量来更新每个点元的权重,通过新的权重执

以天津市南开区水上公园和西青区农学院的4种湿地植物千屈菜、荷花、蒲草、芦苇为试材,对其叶片中过氧化物酶活性(POD)、超氧化物歧化酶(SOD)活性进行测定分析,探究其生理特性。结果表明:芦苇和蒲草的生理特性优于千屈菜和荷花,其中以荷花的最弱。在水上公园生长的植物其生理特性普遍好于天津农学院东校。
Un-tuned large volume airgun array in a water reservoir is recently proposed as a new way to generate seismic waves on land. It can be used to explore the earth velocity structure and its temporal var
It is well known that quantitative estimation of slip distributions on fault plane is one of the most important issues for earthquake source inversion related to the fault rupture process. The charact
Accurate simulation of seismic wave propagation in complex geological structures is of particular interest nowadays. However conventional methods may fail to simulate realistic wavefields in environme
A shear-wave velocity model of the crust and uppermost mantle beneath the SE Tibetan plateau was derived by inverting Rayleigh-wave group-velocity measurements of periods between 10 and 70 s. Rayleigh
