Abstract Acoustic Gas Thermometry (AGT) is one of the most accurate methods measuring thermodynamic temperature. The principal work this research design measurement platform AGT with a Pulse tube refrigerator temperatures between 4.2∼20K. static simulation spherical resonator are concluded. Stress checking and heat leakage analysis system emphasized. will be experimental used in future.

Shape transformations of two-component vesicles in which the spontam .. 'Qus curvature depends on the local compositions in the two monolayer:s are invest igated theoretically. Even if the two components do not ellhibit la1l.'ral phase separation in spherical ve~icles, temperature-induced shape transformations cause lateral phase segregat ion. Vesiculation of sma ller buds is favored in the two...
