Abstract

The utility model provides a gas intensity of pressure probes device with velocity of flow relation, characterized by: include battery, acousto -optic generator, switch, reach the wire of establishing ties, the switch is placed in the sheetmetal of both sides and is stretched over the tinsel of placing between two sheetmetals by the branch and constitutes, the tinsel covers on buckling into arched stereoplasm cardboard and the both ends of cardboard, the inboard formation to airflow channel of arch of cardboard, the cardboard hangs on the dynamometer of top. Airflow channel to cardboard arch below blows, and cardboard pulling spring moves down and the processing circuit switch, being unfavorable for in the fluid that the phenomenon of observing turns into interesting to listen to music, the light that glitters, and the change of dynamometer registration, has strengthened experiment effect and interest, and the perceptual knowledge is deep, helps strengthening student's liking physics.
一种气体压强与流速关系探究装置,其特征是:包括电池、声光发生器、开关、及串联的导线,所述开关由分置于两侧的金属片、及横跨放置在两金属片之间的金属箔片构成,所述金属箔片覆盖在弯折成拱形的硬质纸板上以及纸板的两端,所述纸板的拱形内侧形成为气流通道,所述纸板悬挂在上方的测力计上。向纸板拱形下方的气流通道吹气,纸板拉动弹簧向下移动并接通电路开关,把流体中不利于观察的现象转化为动听的音乐、闪耀的灯光、及测力计示数的变化,增强了实验效果及趣味性,感性认识深刻,有助于加强学生对物理的喜爱。
