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 residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.
