We also prove the following properties : the stable states of the network in the same sh orbit have a same dynamical behavior, such as the size of attraction basin and the energy ; the relation of the symmetry of two isometric networks h and h ' = g - h is s ' h = g - sh - g ~ } for any isometry g, where sh and s ' h are the symmetry of h and h " respectively ; the isometry will not change the dynamical properties of the stable states set of the corresponding networks ; etc.
） g的對稱性s _ h和s _ n的關系為s _ h = g ? s _ h ? g ~ （ - 1 ） ；等距變換不會改變網路穩定態集的動力學性質等一系列的結論。所有這些研究結果表明了hebb學習法則是通過調整網路的連接矩陣，使得其的結構的對稱性包含存儲樣本集的對稱性這一存儲機理。 -
Our results suggested the accumulation of ft in muscle was not the only factor that affected " spectrum shift " during muscle fatigue. the decline of the firing rate of motor units, the synchronization of motor units and an inadequate cns drive may be the important mechanisms that attributed to the change of semg signal during isometric contractions
本研究認為肌肉疲勞過程中h ~ +濃度升高不是導致肌電功率譜曲線左移的唯一因素，運動單位放電頻率下降、中樞驅動減弱和運動單位活動的有序性或同步化可能是肌肉活動時肌電信號變化的一種重要機制。
