Of 18 us and uk - based companies specialising in semiconductors and related devices , which gave their views to the ft in an informal poll , a third said worries about potential loss of important technologies through intellectual property violation might inhibit them , or had already done so , from setting up new production or research operations in china 在《金融时报》对18家英美半导体及相关元器件企业进行的一项非正式调查中,三分之一的企业表示,由于担心知识产权遭到侵犯,造成重要技术落入外人之手,他们有可能(或者已经)决定不在中国进行生产或科研活动。
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 本研究认为肌肉疲劳过程中h ~ +浓度升高不是导致肌电功率谱曲线左移的唯一因素,运动单位放电频率下降、中枢驱动减弱和运动单位活动的有序性或同步化可能是肌肉活动时肌电信号变化的一种重要机制。
