There are 16 pressure-measurement points on the ring equipped with the hot-cathode gauge ( UHV-24), the cold-cathode gauge ( IKR020) and the Pirani gauge ( TPR010). 环上设16个真空测量点,配有热阴极规管(UHV-24)、冷阴极规管(IKR020)及皮氏规(TPR010)。
Based on theory of heat transfer, the relationship between the Pirani gauge structure, pressure and Pirani gauge film resistor has been obtained. 从基本传热理论出发,得到了皮拉尼薄膜热敏电阻与皮拉尼的关键结构尺寸、气体压力的解析关系。
