【摘要】 生物高分子的空间构象取决于高分子的弹性 ,Helfrich发展了一种手征弹性理论来解释高分子的这种构象 ,取得了很大的成功 .但近来实验表明 ,高分子能够在空间形成新的构象 ,诸如螺旋双稳态现象 ,Helfrich理论在解释这些新现象时遇到了一些困难 .为了解释这种新的现象 ,将Helfrich手征弹性理论从四阶推广到七阶更多还原

【Abstract】 The structure of biopolymer is determined by the elasticity of it.Helfrich proposed a chrial elastic theory which succeeded in explaining these structures.However,there exists some difficulties in explaining new structures such as bistable helices.For interpretating these new phenomena,the theory is generalized from fourth order to seventh order.更多还原
