泗濱浮石超聲波檢測報告

Ultrasonic Pulses Test Report of Sibin Stone

泗濱浮石是製作「磬」的材料。敲擊泗濱浮石能發出很強的音響。與此同時是否還有超聲波脈衝發出，用人的耳朵是聽不到的。在中國地震局地球物理研究所的岩石力學實驗室對泗濱浮石進行了超聲波檢測。其結果如下表所示。

Sibin stone can be made as a musical instrument-Qing (aka Chime Stone or An Inverted Bell, an ancient percussion instrument made of stone or jade pieces hung in a row and struck as a xylophone). A loud sound can be produced when you beat on the Sibin stone, but we are unsure the ultrasonic pulses can be produced at the same time. It is because we cannot see it. Therefore, the Institute of Geophysics, China Earthquake Administration conducted a test of ultrasonic pulses for the Sibin stone, results are shown as below:

Number of ultrasound pulses per strike of Sibin Bian-Qing

超聲脈衝的頻率20kHz ─ 2MHz之間。豐富的超聲波脈衝可對人體產生生物物理效應。近年來國內外的研究表明，超聲波脈衝有疏通經絡、改善微循環、抑制癌細胞生長和消除體內多餘脂肪沉積的作用。砭具作為一種醫療保健工具（最主要是利用遠紅外線及超聲波脈衝來達致醫療作用），因此其發出的超聲波脈衝是否豐富，是其中一個判定砭具優劣的因素之一。用不同的材料製作的板(砭板或刮痧板)刮擦手指背，同時將超聲波傳感器安置在板上測量超聲波脈衝。測量結果列於下表。

The frequency range of Ultrasonic Pulse is from 20kHz to 2MHz. A great quantity of Ultrasonic Pulses can bring the Biophysics effect in the human body. Many research show the ultrasonic pulses can dredge human body’s channels, improve microcirculation, eliminate heat and poison, and remove the unnecessary grease. The Bianstone as a medical instrument, we use it to rub the body for dredging human body’s channels and the acupuncture point during the therapy. Therefore, how many ultrasonic pulses can be produced is one of the factors to define the bianstone therapeutics instruments are in good quality or not. We do the test to find out the frequency range and average times of ultrasonic pulses can be produced by rubbing of different kind of stones. Use different kind of stones to make the plate (bian plate or scrapping plate) to rub the finger, at the same time we put the ultrasonic pulse sensor on the plate to collect the data. Test results are shown as below:
