Dead mappings could be eliminated by periodically scanning the map, calling get on each weak reference, and removing the mapping if get returns null.
可以通过周期性地扫描Map，对每一个弱引用调用get，并在get返回null时删除那个映射而消除死映射。
Among their top concerns are staying valuable to their employers (22%), fears that their jobs will be eliminated (20%) and that tech projects will get canceled (12%).

The interpolation is equal to subdivide those control rules, so the quantization error can be eliminated thoroughly, and the system can get better steady-state performance.
使用插值算法相当于细分了控制规则，从根本上消除了量化误差，改善了系统的稳态性能。
Next, we get the minutiae directions by searching the largest extension distance. Finally, according to the relative location and relative direction between minutiae, false minutiae are eliminated.
通过搜索方向延伸向量中最大值对应的方向获取细节点方向；
