摘要
本文用数值和实验方法分析了复合圆映象和单一逆圆映象的超临界标度行为。研究结果证实了两条主要标度规律的存在:S(f)∞f-δ和t∞|f-f_c|^(-r)。对于单一逆圆映象,标度常数γ不随映象阶数变化:γ=0.5;对于复合圆映象,γ有两个值,且δ和Y_2的值均随映象阶数的上升而增加。
The process of a relaxation oscillation can be described by complex circle maps, which reduce to single inverse circle map when the falling time of the process in the oscillation is zero. The order of map is determined by the function form of the modulation signal. Supercritical behaviors of the oscillation ave studied experimentally and numerically. Two scaling laws, namely s(f) ∝f-δ and τ∝|f-fc |-γ are certified, in which for single circle map the exponent γ = 0.5 and does not change with the order of map, but for complex circle maps, there are two values in γ and both the scaling exponents S and γ2 increase when the order of the map is getting larger.
