Among all the export commodities, the increase of machinery and transport equipment"s export is rapidest and most obvious. Therefore, it is necessary to make an analysis about whether China"s machinery and transport equipment have comparative advantages.This thesis reviews the history of the comparative advantage theory at first and points out their different influences on the developing countries economic development. Then the thesis explains the forms and the decisive factors of the comparative advantage in detail and analyses the inherent mechanism under which these factors impel the comparative advantage to change.

本文首先回顾了静态比较优势理论和动态比较优势理论的发展历史，并指出了它们对发展中国家经济发展的不同影响；然后详细阐述了动态比较优势的表现形式和决定因素，分析了这些因素促使动态比较优势转变的内在机制；然后结合显示性比较优势指数以及净出口指数对我国的出口商品以及机械与运输设备进行分析，指出我国出口的机械与运输设备正处于一个转型时期，并将我国的该大类产品和同期的韩国该大类商品进行了比较，指出我国机械与运输设备商品所面临的问题。

Based on the mechanism of nitrogen transfer among different rice leaves, red edge slope and red edge position of the most upper and the 3rd expanded leaves were investigated specially. And using the two red edge parameters (red edge slope and red edge position), a new vegetation index (red edge curve shoulder angle vegetation index, abbreviation RSAVI) was calculated to detect rice nitrogen nutrition status.

基于氮素在水稻不同功能叶片之间运转规律的机理，文章重点分析了第一和第三完全展开叶红边斜率和红边位置的变化，并基于红边位置和红边斜率构建了一个新的植被指数（命名为&红边曲线肩夹角植被指数&，简称为RSAVI）监测水稻氮素营养状况。

According to thefunction, the conclusions for L.olgensis and C.lanceolata are asfollows:1CCF＜200,showing growth with constant tree number;2200≤CCF≤300 transition from growth with constant tree number to theself-thinning,in other words,the change of SDI can be described aslinear combination between the growth with constant tree number andthe self-thinning;3CCF＞300,growth in the self-thinning.

建立了CCF与林分密度指数和单位面积林木株数之间的函数关系式，并对长白落叶松和杉木得出：(1)CCF＜200。林分为等株数生长：(2)200≤CCF≤300时。为等株数生长向自然稀疏生长的过渡期，该期间林分密度指数的变化可用等株数生长和自然稀疏生长的线性组合来表达：(3)CCF＞300时，林分为完全的自然稀疏生长
