在物理方法雄性避孕实验研究中,需要测量睾丸温度、体心与睾丸的温差及加热下的睾丸温度。我们用铜—康铜作热电偶材料,用环氧树脂作绝缘和封固材料,将热偶封固于6号医用注射针中,使热偶接点位于针尖处。注射针起固定、支持和辅助穿刺作用。用光点反射式检流计作二次仪表。在冰点及体温上(37℃)用精密水银温度计校准,用线性函数分度并外推至50℃左右。 In the physical methods of male contraception experimental study, the need to measure testicular temperature, body temperature and testicular temperature and testicular temperature under heat. We use copper - Hong Tong as a thermocouple material, with epoxy resin insulation and sealing material, the thermocouple sealed in the No. 6 medical injection needle, the thermocouple junction at the tip. Needle from the fixed, support and assisted puncture effect. With spot reflection galvanometer for secondary instrument. At freezing and body temperature (37 ℃) with a precision mercury thermometer calibration, linear function indexing and extrapolation to about 50 ℃.
