The fluoride concentration in the trapping solution is determined directly in the diffusion dish, after neutralization and buffering with a fluoride-sensitive electrode.
采用氟化物敏感电极，经中和和缓冲，在扩散盘中可直接测得捕集溶液中的氟化物浓度。
Otherwise, the hybrid algorithm can avoid trapping in local optimum and does not need initial feasible solution.
另外，该算法可有效避免陷入局部最优，也不要求提供初始可行解。
