This tree implementation (package com.icl.saxon.tinytree) takes up far less memory and is quicker to build, at the cost of slightly slower tree navigation.

该树实现(包com . icl . saxon . tinytree)占用极少的内存，并且构建过程更迅速，但其代价是浏览树的速度会稍微慢一点。

At this cost however, Nokia's free voice-based navigation alone could make it worth the spend.

Though direct revenues alone would not make Galileo profitable, adding in the indirect economic gains resulting from better navigation of land, sea and air vehicles would produce a benefit-to-cost ratio of as much as 4.6 to 1.
