进行各种电阻温度测量时,建议使用三根导线的热电阻探测器电缆。这样就可降低环境温度对电缆的影响。
With all the resistance-temperature measurements, the use of three conductor RTD cable is recommended. The effect of ambient temperature variations on the cable is thereby minimized.
氮气是惰性气体,膨胀系数低,不轻易随环境温度上升而上升,可较长时间维持正常胎压,大大降低爆胎几率。
Nitrogen is the inert gases, low expansion coefficient, not easily with the environmental temperature rise for a long time, can maintain normal tire pressure, greatly reduce the flat tire.
来自美国的新研究发现严重的头痛比如偏头痛和季节有联系,特别是周围环境温度增加和较小程度气压降低的情况下。
New research from the US found that severe headaches such as migraine were linked to changes in weather, particularly to increased ambient temperature and to a lesser extent lower barometric pressure.
