This development work will apply to multiple MEMS applications from RF filters to micro-machined ultrasonic transducers(pMUTs) to high-force piezoelectric actuators.
这是超声换能器仿真的基准模型,也是SAW和BAW滤波器仿真的一个很好的基础模型。
This is a benchmark model for ultrasonic transducer simulation but also a good starting point for simulations of SAW and BAW filters.
计算机可以被编程为检查大型,复杂形状的部件,具有一个或多个换能器收集的信息。
Computers can be programmed to inspect large, complex shaped components, with one or multiple transducers collecting information.
根据这些标准,耳机必须具有至少40kHz的换能器频率性能。
Per these standards, headphones must have transducer frequency performance to at least 40 kHz.
适用于两种流体流之间的相互作用的流体原理也被用于创建换能器。
Fluidic principles, which apply to the interaction between two fluid streams, have also been used to create transducers.
这样使得换能器工作状态更糟糕,更快地升温,这是一个恶性循环。
This in turn causes the ultrasonic transducer to work worse and heat up more quickly, which is a vicious circle.
虽然换能器本身并不能立即适用于目前的设备,但这项研究可能有助于为未来的设备提供信息。
While the transducer itself isn't immediately applicable to current devices, the research will likely help inform future devices.
在多路扬声器系统中,交叉滤波器以及换能器不可避免地引入相位失真,因此也引入群延迟的变化。
In a multi-way speaker system, the crossover filters as well as the transducers inevitably introduce phase distortion and consequently also variations of group delay.
有必要考虑换能器将如何暴露于它正在采集的任何形式的能量。
It will be necessary to think about how the transducer will be exposed to whatever form of energy it's harvesting.
所以我们必须给以换能器良好的冷却条件,一般是常温风冷;.
Therefore, we must give the ultrasonic transducer a good cooling condition, usually at room temperature and air cooling;
在睡眠期间,定期将换能器应用于颈部和头部。
During sleep, the transducer was applied to the neck and head on a regular basis.
频率自动跟踪能保证换能器系统能工作在谐振状态,即焊头振幅的最大化。
The frequency automatic tracking can ensure that the transducer system can work in the resonant state, that is, the maximum amplitude of the welding head.
因此,需要至少一对换能器,但有些拓扑结构使用更多换能器。
Hence, we require at least a pair of transducers; however, some topologies use more than two transducers..
目前有些清洗设备为避免换能器从清洗槽上掉下.
At present, some cleaning equipment to prevent the transducer from falling off the cleaning tank.
目前有些清洗设备为避免换能器从清洗槽上掉下来。
Some cleaning equipment is currently used to prevent the transducer from falling off the cleaning tank.
有数百种换能器,其中许多是通过他们完成的能量改变来指定的。
There are hundreds of kinds of transducers, many of which are designated by the energy change they accomplish.
这反过来又促使换能器工作状态更坏,更快地升温,这是一个恶性循环。
This in turn causes the ultrasonic transducer to work worse and heat up more quickly, which is a vicious circle.
目前有些清洗设备为避免换能器从清洗槽上掉下来。
At present, some cleaning equipment to prevent the transducer from falling off the cleaning tank.
另一种方法是逐个测量换能器的阻抗,以确定在小信号条件下的键合质量。
Another method is to measure the impedance of the transducer one by one under small signal conditions to determine the bond quality.
