生物电池——一种值得重视的环保能源

Biofuel——one kind of green new energy

普通电池能对环境造成严重污染,文章介绍一种新兴的环保型的电池———生物电池。结合生物能量代谢紧密相关的氧化还原反应,给出了生物电池的定义,并作了初步分类,阐述了生物电池的基本原理、主要特点及存在问题,提出了改进效率的几种可能途径。加强对生物电池的研究和开发,对解决环境和能源问题,具有重要意义。

Let E be a real Banach Space, Let D be a nonempty bounded closed convex subset of E and T. D→D be an asymptotically nonexpansive mapping. It is shown that under some suitable conditions, the sequence {xn} defined by the modified Reich-Takahashi Iteration method （1.2） converges strongly to a fixed point of T, where x0 is any given point in D, and {αn}, {βn} are sequences in [-0,1] with some restrictions.
