Newcharacteristics of supply include: the transmission of Net-commodity I through intemet--intemet supply, and the direct supply caused by the reduction in the links of commodity circulation. Because of its unique cost structure, the supply of Net-commodity I is that of zero marginal cost and its supply curve is level. What is corresponding with demand expression is mass customization, and thus leading to the integration of supply and demand.

在供给上的新特点包括：网络商品Ⅰ通过网络的传输——网络化供给；流通环节减少导致的直接化供给；由于独特的成本结构，网络商品Ⅰ的供给是零边际成本的供给，它的供给曲线是水平的；与需求的表达相对应的是定制化供给，由此也导致了供给和需求一体化的趋势。

In Chapter Two, Liapunov functional method and Liapunov function method with Razumikhin techniques are employed to obtain some delay independent stability results for the Cohen-Grossberg neural networks with multiply delays.

在第三章中，我们首先对一般的无时滞Cohen-Grossber神经网络模型建立了几个稳定性定理，即文中定理3.3.1-3.3.4。从其中推论可看出负的自联接起着很大的稳定化网络的作用。然后我们考虑了一般的Hopfiel神经网络模型，运用单调动力系统理论，在对激发函数做出很弱的假定下获得了与时滞相关的稳定性结果，并对时滞的大小给出很多的估计，文中定理3.4.3。

Answer: t3212 is the periodic location update time parameter that is used to force the mobile station to initiate a location update request to the network after this timer expires.

答：t3212 是周期性位置更新时间参数，用来强制移动台在该定时器逾时后自动向网络发起位置更新请求。T3212 越小，网络的总体性能就越好，但频繁的位置更新有两个负作用：一是会使网络的信令流量大大增加，对无线资源的利用率降低。
