This study had two purposes: the first one was focused on the effeteness of CAI in improving motor abilities for an elementary school student with high-functioning autism. The second one was focused on the learning effects transformed into in-line skates skill for the participant.

本研究采用单一受试的多重处实验设计，研究个案为一名国小中级的高功能自闭症学童，自变项为游戏式CAI，依变项为动作能和注意，透过游戏式CAI教学方案的介入后，将所搜集的资进视觉分析与C 统计，所得结果统整后，归纳出以下三项结：一、经由游戏式CAI教学方案的教学介入后，确实能提升个案的整体动作能，并在教学介入撤除后，仍具有维持效果。

Animals in AR and Dex group were sensitized with egg albumin, and in NC group were treated with normal saline as control. After sensitization and reproduction of AR model, rats in AR group received no treatment, while those in Dex group were treated with dexamethasone（5mg/kg, once a day） for 5 days.

NC组为对照组，用生理盐水替代卵蛋白进行同步处理；AR组为变应性鼻炎无干预组；Dex组为变应性鼻炎地塞米松干预组，动物建模后腹腔注射地塞米松注射液（5mg/kg）治疗，每天1次，连续5d。

These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.

这两方面也就是本文中第三章所讲的生成序列和扰动序列，这一章中我们主要研究了这两个因素对分数傅立叶变换算子的影响及它们之间的关系；当然还有另一种看问题的角度就是从算子的周期性和特征子空间的分布的角度，这就是第二章中所介绍的内容，在这里我们给出了两个三周期的分数傅立叶变换算子并比较了其特征性质。

The stress-strain curves of Cu-Zn-Al alloys at different temperatures have been plotted on the tensile machine with the aid of electrometry. The main results were as follows: 1. When specimens were deformed within the range of M_s and M_d, the critical stress for inducing martensitic transformation increased with the temperature, and there existed a linear relationship between them. 2. When specimens were deformed above Af, complete pseudoelasticity might be obtained theoretically, which might be damaged, h...

在拉力试验机上用电测法测绘了Cu-Zn-Al合金在马氏体相变点上下各温度的σ-ε曲线，所得主要结果如下：(1)试样在M_s与M_d之间加载，随着温度升高，诱发马氏体相变所需临界应力增大，且加载温度与临界应力之间存在着线性关系；(2)在A_f点以上加载，理论上可获得完全的伪弹性，但加载温度过高或应变量过大，均会损害伪弹性；(3)试样在M_s点上下温度区域变形，得到的伪弹性回复和形状记忆回复之和在80%以上，但在M_s点附近总回复量出现一极小值，且伪弹性回复在M_f点以下又有所回升。

Barium calcium titanate crystal is a new photorefractive crystal. The BCT crystal has more excellent electrooptics properties than BaTiO_3 and has no phase transition at 5℃, which make this material quite attractive for applications.

钛酸钡钙晶体是一种新型的光折变材料，由于其优于钛酸钡的电光性能及无室温相变的优势，使其具有更大的应用前景。

Because the premise of the establishment model of Thirlwall is that a main factor isn't long-term and constant, but to traditional agriculture, Schultz thought that the main factor of traditional agriculture was long-term constant, if new factors did not get involved lately and elementally, impossibly made it conduct results better, so the education don't influence on the traditional agriculture and then can comprehend.

因为瑟尔瓦尔建立模型的隐性前提是要素并不是长期不变的，而对传统农业而言，所有的要素是保持不变的，并已经达到了最优配置，所以教育对传统农业没有影响就可以理解了。

We can use the ellipsoidal model to calculate the relations of period derivation and braking index with average density.

而我们就可利用椭球模型来计算周期变率和制动系数同平均密度的关系；如果取平均密度约为2.2×10〓克/厘米〓，则周期变率约为5.4×10〓秒/秒，制动系数为-0.4。

In the present paper, we shall show that there are many elliptic invariant tori of the equation for a given analytic potential which is not necessary to be constant.

在这篇文章中，证明对于给定的解析势函数，不一定是常数，方程存在许多椭圆不变环面，与 Kuksin 和 Poschel 的文章不同的是，不变环面上承载的是高频的拟周期解。
