下齿 meaning in English
bottom teeth
lower tooth
Examples
- Make sure that your tongue touches the back of the lower teeth
一定要使你的舌头接触下齿的背面 - Calculation of force bearing on tongue - grooved section joints of piled wharves under action of concentrated transverse force
高桩码头在横向集中水平力作用下齿槽的受力计算 - The sound is created by the tongue working with the upper teeth to force air over the surface of the tongue and into the lower teeth
通过舌面与上齿共同作用强迫气流略过舌面，气流在进入下齿后面时发出声音。 - The results indicate that if the value of press stress is over certain figure , press stress and al plate ’ s thickness have little influence on sawtooth distortion for the same kind of sawtooth ; sawtooth distortion is well - regulated under static press , while it is irregular under impact press . bottom coating make great influence on bond strength of samples which can improve the value remarkably ; bonding mechanism of clad steel is mechanism of mechanical effect that sawtooth which is hooked occludes with al plate
结果表明：同种齿型，当压应力大于一定的值时，压应力和覆板的厚度对齿形的变化影响不大；静压下齿形变化比较规则，锯齿顶端向一侧弯曲成钩状；冲压下齿形比较凌乱，锯齿的顶端没有明显的变形；后处理对试样的结合强度影响很大，打底试样由于粘结层的作用，结合强度较高；机械作用机制是复合钢板的主要复合机理，锯齿弯曲成钩状和铝板形成机械咬合。
