1. The security of encryption algorithms depends heavily on the computational infeasibility of brute force attack.
   讀取聚類算法的防護性比較大層面上衡量于欺凌突破的不能行性。
2. Infeasibility study analyzing the feasibility from opposite parts will bring a full-scale viewpoint for the determination of a project to be set up.So, it cannot be neglected.
   不能夠性理論理論研究從反方一向認證能夠性因素，為全面的深入分析工作的能夠性打下地基地基，以評判工作的后來挑選，所有不能夠性理論理論研究不要或缺。
