采用固体内声速与温度的关系,是高温测量新方向的基础。本文研究用细金属传声管制作惰性小的声学温度计的可能性。1.声学温度计的作用原理和主要元件模拟装置的方块图如图1所示。脉冲发生器1产生持续时间不长的(约0.5～1.5微秒)矩形视 The use of solid-internal sound velocity and temperature relationship is the basis for the new direction of high temperature measurement. This article studies the possibility of making inert, small acoustic thermometers with fine metallic sound tubes. 1. The principle of acoustic thermometer and the main components of the simulation device block diagram shown in Figure 1. Pulser 1 produces a rectangular view that lasts for a short time (about 0.5 to 1.5 microseconds)
