Loci of Moving Points with Constant Ratios of Distances from two Fixed Lines

Zhang Huiling(Department of Mathematics,Gansu Education college,Lanzhou,730000)  
This paper discusses the loci of moving points with constant ratios of distances from two fixed lines.It gives the types of surfaces rdpresented by the loci with respect to the three cases of two given straight lines' paralleling,intersecting and being non-coplanar and handles the corresponding locus problems on two-dimension plane as the particular cases of above gained results.
