| Abstract: | In acoustic principle,it could amplify pressure ratio and pressure amplitude at outset of engine by a tube which is a quarter wavelength in length between standing thermoacoutic engine and pulse tube cooler. In this case,a lowest no-load refrigeration temperature of 79.7 K was obtained. |
