The polysemous development among the three verbs is explained in terms of the hypotheses about the frame-to-frame transferring and the conceptual schema requirement for triggering the individual verb in a frame to be transferred into another frame. Furthermore, among the three verbs, only biaoshiI is a fully representative member of the source domain, i. e., the Statement frame, and thus capable of being extended to other domains, i. e., the Encoding and the Evidence frames. Here, lexical membership in the source frame or frame-representativity is the key to semantic extension.
为了解释这三个动词语义差异的现象，我们指出了框架到框框间转换的假设和让一个动词从一个框架移动到另一个框假所需的概念基模要求，并且进一步提出「框架代表性」(frame-representativity)的原则，说明「表示」做为「来源领域」最具代表性的一个词汇，因此可以从「陈述性的框架」延展到其他的框架。
By calculating logging responses in homogeneous medium formation and twolayer jump formation, Numerical solutions are consistent with analytic solutions, which shows that the Finite Difference Time Domain method is an effective tool to compute responses of high frequency electromagnetic wave logging. 2. By using representative formation models, it is obtained under a given operation frequency and a given spacing that the effect of borehole radius is small, which we can ignore generally speaking; the more the thickness of target zone is, the less the effect of shoulder beds is; phase shift curves compared with amplitude ratio curves have a bad radial investigation depth, with a good vertical resolution; phase shift curves can distinguish the thin sand-shale interbeded formation.
本文采用典型的地层模型，在某一特定源频率和源距情况下，得出了测井响应与井眼半径、井内泥浆、围岩、围岩薄夹层及侵入半径的关系，即井眼半径和井内泥浆对测井响应影响较小，一般情况下可忽略井眼的影响；目的层厚度越大，围岩的影响越小；幅度比曲线受围岩的影响更严重；相位差曲线的纵向分辨能力优于幅度比曲线，但探测深度浅；视介电常数测井曲线能够识别砂-泥岩薄互层。
The new technological revolution in recent years, taking Internet as representative is guiding tradition telecommunication concept and structure system to develop to a brand-new direction, open to the outside world gradually with switching in the net marketplace's in every country as well as telecommunication controls policy's gradually loosen, new business need competes for hegemony in the domain feeling more upright, as performing more being continuing without end in war, before gigantic market potential drive down, the ceaseless maturity having produced the all kinds of cut-over net technology, technologies such as wired cut-over and wireless cut-over has accelerated respective commercial step.
摘要近年来，以互联网为代表的新技术革命正引领着传统的电信概念和结构体系向一个全新的方向发展，随着各国接入网市场的逐渐开放以及电信管制政策的日渐放松，新业务需求在越演越烈的地盘争霸战中层出不穷，在巨大的市场潜力驱动下，产生了各种各样的接入网技术，有线接入和无线接入等技术的不断成熟加快了各自的商用步伐。
