| 摘 要： | Klumb-schwarz提出的同轴圆筒形辐射真空计,原则上可以作为低气压的绝对量具,然而由于迄今并未有人提出完整的灵敏度理论,困此限制了它作为绝对量具的可能性。本文叙述一种近似解法,可以得出灵敏度的绝对值,并从理论上决定其最佳几何结构。最后还对这种真空计的量程上下限作了讨论。

| Abstract: | Klumb-Schwarz type radiometer gauge (Knudsen gauge) is an absolute gauge for high vacuum measurements, but since its theoretical sensitivity is so far unknown, in practice it needs calibration against another absolute gauge (e. g. McLeod). In this paper a simple theory to determine the sensitivity of a Klumb-Schwarz gauge is described. The optimum angle of the vane is decided as 24° by theoretical considerations. It is further shown that in this gauge the force due to electromagnetic radiations limits the lower range and is something in analogue with the soft X-ray effect in conventional hot-cathode ionization gauges. |
