这是一台能产生超声波的仪器。 |
| 3. | The application of cavitation of ultrasonic wave in chemical engineering of polymer
超声波的空化作用在聚合物化工中的应用 |
| 4. | The very short wave lengths of ultrasound make a great difference in what ordinary sound waves can do
超声波的波长极短，其功能与普通声波相比大不相同。 |
| 5. | Standard practice for the measurement of the apparent attenuation of longitudinal ultrasonic waves by immersion method
用浸渍法测量纵向超声波的表面衰减的标准操作规程 |
| 6. | However , ultrasound doesn ' t show obvious effect on the reactions , which maybe attribute to the fast hydrolysis reactions of products
超声波的作用不明显，可能与松香酯在超声波体系易水解有关。 |
| 7. | The system could measure certain distance with the reflected wave on condition in which the speed of transmitting wave is fixed
该系统以空气中超声波的传播速度为确定条件,利用反射超声波测量待测距离。 |
| 8. | The iatrical ultrasonic is about 1 - 15mhz at present , which generated by piezoelectricity crystal at the function of alternant electric field
目前，医用超声波的范围多在1 15mhz ，是由压电晶体在交变电场作用下发生机械振动而产生。 |
| 9. | The solution was alkaline , and formaldehyde ( hcho ) was used as a reducing agent . plating was carried out at middle temperature / low temperature and ultrasonic radiation
化学镀铜溶液为碱性的甲醛为还原剂的镀液，镀覆在室温、超声波的条件下进行。 |
| 10. | No , ultrasonic vibrations gently break down the plaque , rather than an actual physical “ scaling ” . you can be rest assured that the procedure is perfectly safe
不会的。洁牙机是通过超声波的震动而不是磨除牙石的，因此不会损伤牙齿。定期洗牙会保持牙周组织的健康。 |
