另外，对路径偏移中出现的缝隙给出了填补方法，并使偏移后的路径轨迹延伸至曲面边界。

Furthermore, a method is presented to fill the gaps between paths and extend the endpoints of path trajectory to the surface boundary.

如清单 1 中所示的任何查询都有到指定数据的精确路径，DBMS 可以迅速地在均衡树和字节偏移编码中确定它。

Any query such as the one in Listing 1 has a precise path to the specified datum, which a DBMS can quickly determine in balanced trees and byte-offset codings.
