We introduce a noise-resistant algorithm for reconstructing a watertight surface from point cloud data. It forms a Delaunay tetrahedralization, then uses a variant of spectral graph partitioning to decide whether each tetrahedron is inside or out

逆变器的PWM控制，滞环、三角载波等控制方法的研究。-PWM control inverter, hysteresis, triangular carrier control methods such as research.

BG是标注标高 三角符号+高程， PLO是批量打印(使用R14)-BG BB marked elevation the triangular symbol+ elevation, PLO PIO batch print (using R14)
