Chapter 3 describes somemeans to measure harmonic and compares two most popular of them. As the mainpart of this thesis, chapter 4 presents the whole process of building the simulationmodel of the water-heated system.

论文第三章列举了多种谐波检测的方法，比较了各种谐波检测方法的优缺点及目前的应用状况，并主要对其中的两种算法，即快速傅立叶变换法和小波变换法进行了对比和分析。

Leaves sessile; blade broadly oblong or oblong-ovate to narrowly oblong or oblong-lanceolate, 2-6.5(-8)× 1-3.2 cm, thickly papery, abaxially rather paler but not glaucous; laminar glands dense, unequal dots or short streaks; intramarginal glands dense; main lateral veins 4-6-paired, with densely reticulate tertiary venation not or scarcely prominent abaxially; base cordate-amplexicaul, apex rounded to shallowly retuse.

There are distinct correlativity between chlorophyll content , soluble protein content and Rubisco content of the rice under the different N level. The three contents of different position leaf of jowar and maize presented one peck in the middle leaves floor, which gave them great matters for photosynthesis.

各施氮处理下水稻Rubisco含量、叶绿素含量和可溶性蛋白含量三者之间都存在显著的相关性；研究了高粱和玉米两种C_4植物不同叶位叶片Rubisco含量、叶绿素含量、可溶性蛋白含量，结果表明在营养生长期两种C_4植物叶片的这三个生理活性从上到下都呈现中间高两边低的趋势。

如同《创世纪》，野心勃勃不择手段的叶荣添，起先正直善良后又无恶不作的许文彪，还有奴隶道德不辨忠奸的滥好人马志强--康三目的性明确、偶有绝望却勇往直前，康大性格坚韧、不动声色一味死捱，康二没甚原则、却相信希望在人间，上夜校吃盒饭跨水塘也安之若素。

During the course of water stress, along with the extension of coercion and the intimidation of the deepening,the Pn of P.euphratica and P.pruinosa experienced three phases:sharp decline-slow, rebound -down and again under moderate and serious stress condition.16 and 24 days later after water stress starting,the reason of Pn drops mainly is the stomatal limit,and 48 days later,primarily is non-sto matal limit.

3在水分胁迫进程中，随着胁迫时间的延长及胁迫程度的加深，中度和重度水分胁迫下胡杨、灰叶胡杨的净光合速率经历了急剧下降-缓慢回升-再下降三个阶段。

Especially, the theory of univalent harmonic mappings plays an important role in the theory of minimal surface.

本文的第三章及第四章对单叶调和映照进行了深入的研究，得到了一系列的结果。

The pavement system is modeled as a plate extent on a viscoelastic foundation, and the triple Fourier transform is used to analyze the dynamic strain response of rigid pavement subjected to moving vehicle loads.

把刚性路面建模为黏弹性地基上的板，用三次富立叶变换的分析方法分析了移动车载下刚性路面板底动态应变的响应。
