Applying the theory of rheodynamics and hydraulic theory, a relationship of damping vs. vibration velocity, electric field strength and gas-filled pressure has been set up.

分析了阻尼力与振动速度、外加电场强度、充气压力等的数学关，振器设计参数的化研究提供了理。

At highest field strengths, the core of the clot may have low signal on T2-weighted images, due to the presence of intracellular methemoglobin or of deoxyhemoglobin.

高场强时，血块的中心在T2加权像上是低信号影，这是由于细胞内的高铁血红蛋白或还原型血红蛋白存在产生的。
