查询词典 elastic wave

If the elastic limit is exceed, the material will not return to its original dimensions, and will be deformed; thematerial is said to be elastic partly elastic s and partly plastic.

In this paper,author's research starts from the thermal expansivity and thermal transmission theory in physics,then utilizes the thermo elastic theory in mechanics of elastic bodies and the solution of statically indeterminate system in mechanics of materials as well as the interaction principle between soil and elastic body,finally gets the correct thermal stress analysis formulae of shaft-wall.

长期以来，在基岩段井壁结构的设计中，一直将地压作为结构设计的影响因素，实际上是不完善的；对于煤矿的进风井，井壁的温度随季节而变，因此，温度因素同样的应该考虑到井壁结构的设计中去；因此，将遗漏的因素补充入传统的设计理论中，是目前十分紧要的一项研究工作。

The coupling effect between elastic deformation and the rigid motion was concerned in the dynamic equations. At the same time, the flexible manipulators were assumed as Euler-Bernoulli beams, the elastic deformation of the manipulator was represented by modality truncation equations, both elastic and gravitational potential energy were considered to calculate the total energy for whole system, therefore the finial dynamic modeling is more accurate and simple than others published.

Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

根据橡皮管的体外实验结果，利用超音波以及影像分析所得到的橡皮管尺寸，与实际尺寸间的误差只有3%，而使用超音波 B-mode 量测颈动脉的实验结果显示，在把颈动脉当作完全弹性体的假设下，所得到的 CIMT 硬度指标，於十位平均年龄为23.6岁的年轻健康男性中，结果与过去文献中常使用的 Peterson's elastic modulus 相比较，结果显示容易受到不同受试者间，不同的生理状态之影响，而在考虑受试者的 IMT 变化情况下，比能够反映更多的受试者颈动脉材料性质，因此得到了较为稳定的实验结果。

The model prediction is also compared with other theoretical models, for example, the Hashin-Shtrikman model for elastic constants and Kerner and Schapery models for thermal expansion coefficient. The model proposed in the present study shows similar precision on the properties of composites as the elastic modulus ratio is lower than 10. However, the elastic modulus ratio is higher than 20, the model proposed in the present study shows improved prediction on the properties of two-phase composites.

并与文献上其他理论模式进行预测性质之比较，例如：用於预测弹性常数的Hashin-Shtrikman模式、以及用於预测热膨胀系数的Kerner 及 Schapery模式，经由比较结果显示，当弹性系数的比值小於10时，本研究所建立的模型之预测值与其他理论模式有相似的精确预测功能，但是当弹性系数的比值大於20时，对於双相复合材料之弹性及热膨胀性质预测，本研究所建立的模型具有较佳的预测结果。

The formula was established about calculating design parameters and technological parameters of ideal strip and bent strip in the period of forming.
