The Pade approximation is combined with 3-D frequency-domain finite difference (3D-FDFD) for the first time. The impact of expansion point and the order of rational function on the accuracy and the convergence radius is discussed in this dissertation.

主要包括以下内容：首次将Pade逼近运用到三维频域有限差分法中，详细讨论了Pade逼近中展开点选取、收敛半径与有理阶数的关系问题。

In order to find an efficient way to enrich the silicon dioxide(SiO2) in straw, cornstalk was taken as an example. In this research, a new process consisting of steam-explosion, carding, sifting was employed to fractionize the cornstalk, followed by the quantitative analysis of silicon dioxide of the different parts of cornstalk.

为了研究秸秆中SiO2的富集方法，该文以玉米秸秆为研究对象，利用汽爆、梳理加筛分的方式对秸秆进行分级处理，并采用重量法、扫描电镜和X-射线衍射等技术对分级前后秸秆中二氧化硅的含量、迁移规律以及结构变化进行了分析。

The aim of this paper is to study the countability on I-fuzzy topological spaces.

本文主要是研究I-fuzzy拓扑空间中的可数性，提出I-fuzzy第一可数性、I-fuzzy第二可数性、I-fuzzy可分性、I-fuzzy Lindelf性等几种可数性的概念，界定了它们的特征性质，给出了它们之间的关系，还在第一可数I-fuzzy拓扑空间中用多值序列收敛对映射连续性进行刻画，更为重要的是得到了I-fuzzy拓扑空间中的I-fuzzy Lindelf定理。

The integrated aberration-reduced gratings are the key elements in high capacity optical network using wavelength routing and forming the basis of an optical cross-connect, they are used in demultiplexer.

现代谱仪中的光电探测元件一般是平面型的，消像差光栅是平场谱仪的关键元件。微型消像差光栅也是光通讯中的无源波分复用器的核心元件。

This paper analyzed the carbon isotopic ratios of tw o cryptoMeria, collecting froM West TianMu Mountain, Zhejiang, and studied th e t ree-ring carbon isotopic ratios evidence, for the atMospheric CO2 concentrati on change after Industrial Revolution.

植物在同化大气CO2过程中产生碳同位素分馏，因此，树轮中稳定碳同位素比值（1 3C/12C）不仅是重建古气候的工具，也是过去大气CO2浓度变化的敏感指示器。

Limit cycle flutter of a two-dimensional airfoil in cubic nonlinear aeroelastic system in incompressible flow is investigated.

引 言 在不可压缩流中的二元机翼是一个典型的自激振动的例子，在该系统中引入非线性项一般会产生如Hopf分岔，极限环颤振[1]，周期倍化及混沌等现象。

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

结果显示：接种后6 d的根尖分生区、伸长区出现膨大、对称的根结，根中心的原形成层细胞分化出巨型细胞；10 d在根毛区及以上部位出现既有对称又有偏于一侧的根结，周围有原生木质部导管出现，根结中巨型细胞阻断了导管；16 d次生维管组织提早出现；20~30 d导管纵向排列无序，形状扭曲，皮层中有新维管组织产生。

Therefore, disease in the population has become more common recently. In view of this, submicron Negative-Ion powders and excited materials were adopted in this research. The submicron NI powders and excited material powders were treated with a dispersing agent and a ball mill used first, then it was blended evenly into water-borne polyurethane by a planetary deaerate stirring machine, and finally the water-borne PU composite films were coated onto release paper with a coating rod. The main purpose of this work is to manufacture a permanent composite film which is able to release NIs. Such film is expected to not only release amounts of NI but also absorb smells and effectively create fresh air.

有鉴於此，本研究采用次微米负离子粉体及激发材，先添加分散剂后利用球磨机做处理，再将次微米负离子粉体与激发材添加至水性聚氨基甲酸酯中，经由行星式脱泡搅拌机均匀混合，再以湿式涂布法，经由涂布棒涂布於离型纸上，脱膜后成复合薄膜，制备出於空气中释放负离子、吸收异味且清洁空气之永久型复合薄膜。
