Title (EN) MEASURING METHOD AND INSTRUMENT EMPLOYING CRYSTAL OSCILLATOR
(FR) PROCÉDÉ DE MESURE ET INSTRUMENT EMPLOYANT UN OSCILLATEUR À CRISTAUX
(JA) 水晶振動子を用いた測定方法及び測定装置
Abstract:
(EN) Physical properties of an objective substance of measurement are measured exactly by measuring any one of a mass load, a viscous load and a viscoelastic load separately from other loads. The method for measuring the physical properties of a substance touching a crystal oscillator equipped with electrodes on the opposite sides of a quartz plate based on the frequency variation of the crystal oscillator, characterized in that the physical properties of the substance are measured by employing frequencies F1 and F2 (F1<F2) giving one half of the maximum conductance in the vicinity of a resonance point by each frequency of at least two out of N-multiple waves (N=1, 3, 5, ...(N=2n+1)) of the crystal oscillator when a voltage is applied between the electrodes.
(FR) L’invention permet de mesurer les propriétés physiques d’une substance objective de mesure de façon exacte en mesurant l’une parmi une charge massique, une charge visqueuse et une charge viscoélastique séparément d’autres charges. Le procédé de mesure des propriétés physiques d’une substance touchant un oscillateur à cristaux équipé d’électrodes sur les côtés opposés d’une plaque de quartz sur la base de la variation de fréquence de l’oscillateur à cristaux est caractérisé en ce que les propriétés physiques de la substance sont mesurées en employant les fréquences F1 et F2 (F1<F2) en produisant une moitié de la conductance maximale au voisinage d’un point de résonance par chaque fréquence d’au moins deux ondes parmi les ondes multiples de N (N=1, 3, 5, ...(N=2n+1)) de l’oscillateur à cristaux lorsque l’on applique une tension entre les électrodes.
(JA)  質量負荷、粘性負荷及び粘弾性負荷のうちの何れかを残りの負荷から分離して測定し、測定対象となる物質の物性の正確な測定をできるようにすることを目的とする。  水晶板の両側に電極を備えた水晶振動子に接触する物質の物性を、前記水晶振動子の周波数変動に基づいて測定する方法であって、前記電極間に電圧を印可した際の水晶振動子のN倍波(N=1,3,5、・・・(N=2n+1))のうちの少なくとも2つの周波数を使用して、各周波数による共振点付近のコンダクタンスの最大値の1/2を与える周波数F1,F2(F1<F2)を用いて、前記物質の物性を測定することを特徴とする。
