查询词典 intra-urethral

Objective: To explore the mechanisms resulting in the recurrence of urethral scar which make urethral strictures difficult to be cured, a series experiments were conducted to find potential effective factors involved in urethral scar formation and degradation, including the studies of extracellular matrix component of urethral stricture scar, the characteristics of urethral scar fibroblast, and the effects of urine on urethral fibroblast in vitro, as well as the studies to compare the difference of collagenase activity, type Ⅰ collagen and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the tissues and cultured fibroblasts from normal urethra and strictured urethra respectively, and the studies to investigate the effect of antisense TIMP-1 oligodeoxyonucleotide on cell proliferation and collagenase activity of urethral scar fibroblast.

Firstly, it seeks the sources from which theories have been developed, by a summary of evolution or a road-map. Secondly, it explains the two basic forms taken by traditional theories on intra-industry trade, namely, horizontal intra-industry trade model and vertical intra-industry trade model. Both models take final products as trade objects and products of same industry are thus simultaneously exported and imported among developed nations and among developed nations and developing ones.Thirdly, it points out that the theory of vertical intra-industry trade has already been expanded in scope in the area of trade between developed countries and LDCs. It shows that the implication of vertical intra-industry trade has expanded to the importation and exportation of parts and components, intermediate products or processing products produced via various working procedures or different production links within the same industry, with MNCs as carriers. It gives the summary of the methods of measuring intra-industry trade and argues that the basic method adopted by this thesis is G-L Index. In addition, GHM and Input-output Analysis are introduced to demonstrate the expansion of vertical intra-industry trade.

首先，通过整理国际贸易理论的发展脉络，寻求产业内贸易的理论渊源；其次，阐述产业内贸易传统理论的两种基本形式，水平型产业内贸易与垂直型产业内贸易的理论模型，指出两者都以最终产品为贸易对象，实现了发达国家之间或发达国家与发展中国家之间的同一产业内产品的同时进口和出口；第三，结合全球化的特点和跨国公司在国际要素分工中的基础作用，指出发达国家与发展中国家之间的垂直型产业内贸易理论已经得到拓展，表明垂直型产业内贸易涵义已发展成为以跨国公司为载体的同一产业内不同生产工序或不同生产环节的零部件、中间产品或加工产品的进口和出口；最后，归纳了产业内贸易的计量方法，指出本文的产业内贸易基本计量方法是G-L指数(格鲁贝尔-洛伊德计量法)，并在此基础上进一步说明与垂直型产业内贸易的拓展相关的计量方法包括：GHM计量法和Hummels投入-产出分析法。

This scheme was composed of two parts: intra prediction and inter prediction. For the intra prediction part, 8×8 block DCT-HT transform-domain converse was used, and then intra mode decision was done in HT domain to obtain the optimum mode, so that good intra prediction was acquired. For the inter prediction part, Motion Vector got from Variable Length Decoding in MPEG-2 stream was reused as Prediction Motion Vector of H.264, then motion prediction mode and search region were reset, so that better prediction result was acquired.

该方案中，帧内预测使用了8×8块的DCT-HT的变换域转换，然后在HT域进行Intra模式判决得出最优模式，从而得到理想的帧内预测；帧间预测重用了MPEG-2码流中变字长解码得到的运动矢量MV，作为H.264的PMV，通过重新设定运动预测模式以及搜索范围，从而获得较好的预测效果。
