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。

本文在恢复"以太"理论的基础上,进一步假定"以太"就是存在于宇宙间的由正、负电子构成的晶体状弹性物质,并初步建立一个与现有电磁学完全相符的磁场模型,使电磁学的若干现象、事实、规律得以理论上的彻底解释。

The main findings of the empirical analysis include: 1 The decisions concern the choices of auto ownership, mode to work, and auto use were made simultaneously and interrelatedly. 2 The decline in correlation between the choices of auto ownership and use as the number of vehicle increase indicated that to own multi-vehicles in not necessary due to the demand for auto use. 3 Both price elasticity and income elasticity for auto ownership are low. This evidence implies that auto has become a kind of necessity for household. Therefore, the effect of decreasing the tendency of auto growth by means of increasing the cost of owning auto would not be significant. The price elasticities of auto use are between -0.48 and -0.78. 4 There are same underlying factors influencing auto ownership, mode to work, and auto use including: parking time at residential location, accessibilities to work location by auto and transit, auto use unit cost, and the percentage of auto use for work. These factors indicate a direction for the formatting of future automobile policies.

本研究以台湾地区之家户个体资料从事实证分析,实证分析之主要结论如下:1小汽车持有数量、工作者工作运具选择、与小汽车使用量等选择间确有相关与联立性存在;2小汽车持有数量选择与小汽车使用量选择间之相关性会随小汽车持有数量的增加而降低,显示选择持有多部小汽车并非完全基於小汽车使用之需要;3小汽车持有之价格弹性与所得弹性均偏低,显示小汽车已成为民生必需品,欲以提高小汽车持有成本之价格手段来抑制小汽车持有,并无法竟其功,小汽车使用需求之价格弹性则在-0.48与-0.78间;4影响小汽车持有数量、工作者工作运具、与小汽车使用量等选择主要之相关或共同因素包括:家户附近停车状况、私人运具与大众运输工具之工作可及性、小汽车单位使用成本、与小汽车工作使用比率等,以上这些影响因素可为日后小汽车相关政策的研拟提供一方向。

The results show that the petrographic characteristics of clastic rock have an intrinsic influence on its macro mechanical properties and bursting potential.

研究结果表明,碎屑岩的岩石学特征对其宏观力学性质和冲击倾向性具有重要影响作用,随着碎屑颗粒含量的增加,岩石的强度和刚性增强,岩石的脆性增大,弹性能指数和冲击能指数增加,岩石在轴向应力作用下达到峰值强度以后直到完全破坏的持续时间变短,冲击倾向性增强。

In conventional seismic data processing, the earth is regarded as prefectly elastic medium.However,the pores of stratum rock often contain fluid. So, when the seismic wave propagates in it, there are energy attenuation and phase distortion related to frequency. Moreover, the attenuation, scattering,and dispersion of high-frequency components are far higher than that of low-frequency components.
