By using Krasnoselskii fixed-point index theorem, a class of nonlinear functional differential equation x′(t)=a(t)g(x(t))x(t)-λ sum from i=1 to n(f_i(t,x(t-T_i(t)))) is obtained,and at least there are the sufficient conditions to guarantee the existence of two periodic positive solutions, and some corresponding results in existing literatures are expanded.
利用Krasnoselskii不动点指数定理,得到一类带有参数的非线性泛函微分方程x′(t)=a(t)g(x(t))x(t)-λ sum from i=1 to n(f_i(t,x(t-T_i(t)))),至少存在两个周期正解的充分条件,推广了已有文献中的相关结果。

性质:就每一品种的晶体来说,总可找到一套与其基向量对应的晶轴系,从而使晶体的每个晶面在三个晶轴上的倒易截数成简单互质整数之比,即有h*:k*:l*。称为晶面指标的h*k*l*数组一般呈简单、互质有理数的规律称为有理指数定理。基于能量效应的缘由,晶体生长中,晶面间距短、晶面指标小的晶面在实际晶体外形中将占有突出的主导地位。
