1、什么是&濒诲辩耻辞;空化作用&谤诲辩耻辞;？
1. What is cavitation?
&濒诲辩耻辞;空化作用&谤诲辩耻辞;是数以百万计微小气泡(或空穴)在液体中迅速形成并爆裂的现象。&濒诲辩耻辞;空化作用&谤诲辩耻辞;的产生是由于高频声波(超声波)形成的高、低压力波交互作用的结果。在低压阶段，气泡一点点变大，而在高压阶段，其被压缩而内爆。
"Cavitation" is a phenomenon that millions of tiny bubbles (or holes) are rapidly formed and burst in liquid. "Cavitation" is caused by the interaction of high and low pressure waves formed by high-frequency sound waves (ultrasonic waves). In the low pressure stage, the bubble becomes larger little by little, while in the high pressure stage, it is compressed and implodes.
2、我怎样能实现超声波清洗效果？
2. How can I achieve ultrasonic cleaning effect?
有许多条件能够决的清洗效果，其中重要的是选择合适的清洗液，在正确的温度下清洗恰当的时间，选择合适尺寸和类型的超声波清洗机。
There are many conditions that can determine the cleaning effect. Among them, it is important to select the appropriate cleaning solution, clean at the right temperature for the right time, and select the appropriate size and type of ultrasonic cleaner.

3、用超声波清洗会损伤我的工件么？
3. Will ultrasonic cleaning damage my workpiece?
超声波清洗对大多数工件是的。每秒钟数以千计气泡的内爆产生的能量是巨大的，但由于能量集中在极其微小的区域内，因此整个清洗过程是的。对性为谨慎的考虑应该是清洗液的选择。清洗液对某些工件表面潜在的伤害性可能会因为使用超声波而增大。超声波清洗不建议应用于下列宝石：猫眼石、珍珠、翡翠、坦桑黝帘石、孔雀石、绿宝石、青金石和珊瑚。
Ultrasonic cleaning is safe for most workpieces. The energy generated by the implosion of thousands of bubbles per second is huge, but because the energy is concentrated in an extremely small area, the entire cleaning process is safe. Careful consideration of safety should be the choice of cleaning solution. The potential harm of the cleaning solution to some workpiece surfaces may be increased due to the use of ultrasound. Ultrasonic cleaning is not recommended for the following gemstones: opal, pearl, emerald, tanzanite, malachite, emerald, lapis lazuli and coral.
4、什么是&濒诲辩耻辞;直接&谤诲辩耻辞;和&濒诲辩耻辞;间接&谤诲辩耻辞;清洗？
4. What are "direct" and "indirect" cleaning?
直接清洗通常是指工件在装满清洗液的清洗槽内清洗，工件通常装在带孔的托盘或工装篮内。直接清洗的局限性是需要选择那些不会损伤超声波清洗槽的清洗液。间接清洗则是将待清洗的工件放在烧杯或不带孔的托盘内，烧杯或托盘内装有溶液，而不是直接装在清洗槽内。当选择间接清洗时，确认槽内的水位被保持在标准位置。
Direct cleaning usually means that the workpiece is cleaned in a cleaning tank filled with cleaning solution, and the workpiece is usually installed in a tray or tooling basket with holes. The limitation of direct cleaning is to select the cleaning solution that will not damage the ultrasonic cleaning tank. Indirect cleaning is to put the workpiece to be cleaned in a beaker or tray without holes, and the beaker or tray is filled with solution, rather than directly in the cleaning tank. When indirect cleaning is selected, confirm that the water level in the tank is maintained at the standard position.
