声悬浮 meaning in English
acoustic levitation
Examples
- The rapid solidification process of pb - sn eutectic alloy is investigated with acoustic levitation and the maximum undercooling of 38k has been achieved
采用声悬浮无容器处理技术研究了pb - sn共晶合金在深过冷条件下的凝固规律。 - The main influencing factors for containerless processing , such as the gas medium , gravitational levels , resonance adjustment , and temperature variations are studied
对材料声悬浮无容器处理过程中的主要影响因素如气体媒质、重力水平、声场调谐以及温度变化等进行了研究。 - It is found that the levitation force can be remarkably enhanced by choosing optimum value of r or d , and the possibility of this enhancement for spherically curved reflectors is the largest
发现通过选择最优化的r或d值，可以显著提高声悬浮力，并且谐振模式数越小，反射端截面半径越大，提高的程度就越大。 - The present thesis has carried out detailed investigation on the rapid solidification of undercooled bulk water and pb - sn binary eutectic alloy with acoustic levitation , and the various factors influencing the achievement of undercooling in sound field have been analyzed
主要取得了以下几方面的研究成果：研究了5 8mm的大体积水在声悬浮无容器条件下的快速凝固行为。获得了最大为24k的过冷度。 - Single - axis acoustic levitation of the heaviest solid ( iridium , p = 22 . 6g / cm3 ) and liquid ( mercury , p = 13 . 6g / cm3 ) on the earth is achieved by greatly enhancing both the levitation force and stability through optimizing the geometric parameters of the self - developed single - axis acoustic levitator . this indicates that all the solids and liquids can be acoustically levitated on the earth in principle
对自行研制的单轴式声悬浮器进行了优化设计，极大地提高了悬浮力和悬浮稳定性，首次悬浮起自然界中密度最大的固体铱( i - r ，密度22 . 6g cm ~ 3 )和液体汞( hg ，密度13 . 6g cm ~ 3 ) 。
