Endogenous opioids are known to modulate cell growth.

内源性阿片类物质可以调节细胞的生长。

Some video signals modulate the receiving signal in frequency domain,then the resulting signal is retransmitted.

这种干扰信号能获得一定的处理增益，因此能节省干扰功率。

This study is aimed to address the question whether the early discharges can affect thesilent period and modulate the late discharges and to investigate the possiblerole of dysfunction of primary myelinated afferents in generation of chronicpain. In addition, we also investigate the effect of the precedingA-conditioning stimuli with graded numbers on the late discharges of WDRneurons evoked by a following nociceptive test stimulus that activates bothA- and C-fibers.

在定义WDR神经元的反应特性时，通常用一个短促的电刺激刺激相关的神经干，激活A及C类纤维，这时可记录到一个反映有髓纤维传入的高频短促的早成分放电，接着是一个无放电的宁静期，最后是C纤维激活所诱发的晚成分放电，这种放电形式有别于脊髓背角的其它神经元。

A Kerr medium,which possesses a third-order nonlinearity,can modulate the phaseof a field,and play a critical role on the respects of quantum statespreparation,quantum nondemolitionmeasurements anddecreasing quantum noise,and so on.1990,Buzek combined thetwo kinds of basic model together,and presented Jaynes-Cummingsmodel with a Kerr-like medium.He found that a Kerr-like mediuminfluences the statistics properties of the standard JCM greatly.1992,Amitabh Joshi and R.R.

克耳介质具有三阶非线性极化率，基本作用在于调制腔场的位相，近年来在量子态制备和非破坏性测量以及减少量子噪音等方面日益发挥着相当重要的作用。1990年Buzek把这两种基本模型结合在一起，提出了含有克耳介质的Jayness-Cummings模型，并研究了克耳介质对JCM统计特性产生的影响。1992年Amitabh Joshi和R.R。
