On the basis of obstruction information on a routing plane, this router has a high efficiency in time and and space by using the heuristic technique in artificial intelligence.
这个算法以布线平面上的障碍信息为基础，采用了人工智能中的启发式搜索技术，时空效率很高。
2
Flow around an obstruction causes a decrease in melt front speed and leads to high local viscosity and reduced relaxation.
围绕障碍物流动使融化前部的速度下降并产生较高的局部粘性而减少松弛作用。

HF inhaled in high concentrations may cause glottitis (obstruction of the airway) and acute pulmonary edema.
