| Abstract: | Basing on the principle of temperature measurement of LPG, introduced in this paper is a new method to enhance temperature sensitivity in an LPG. That is to coat an LPG with Cargille RI oil which is of high thermo-optic coefficient. Temperature sensitivity of the LPG can therefore be enhanced remarkably. |
