下中音

The key of C has no sharps or flats, but F needs one flat to ensure that a series of consecutive notes starting on F forms the necessary pattern of whole steps or whole tones and half steps or semitones, with a half step or semitone between the mediant and subdominant.

带降号的大音阶开始于F，恰好是C下的第五级。C调既无升号也无降号，但是F调却需要一个降号以确保开始于F调的一系列音形成必需的一组全音和半音，以及介于中音和下属音间的半音。F大调，带一个降号，降B大调开始于第五级，有两个降号，以此类推。

Starting from the tonic or key-note, the scale degrees in ascending order are: tonic, supertonic, mediant, subdominant, dominant, submediant, leading tone or leading note, tonic.

始自主音，调式上行顺序为：主音，上主音，中音，下属音，属音，下中音，导音，主音。导音

In the study, we have found that when the long axis of an elliptical transducer is 2.5 times of the distance between nodal line and the plate center under free boundary condition, the depth of the first dip in mid frequency range of SPL spectrum can be greatly reduced.

从这些关系中可以得到激振器长轴是在自由边界条件下，节线到振动板中心距离的2.5倍时，中音谷会得到比较平缓的结果。

For plates with same thickness and material constants but different aspect ratios, we have studied how the distance from the nodal line of the first bending mode to plate center and the size of transducer affect the depths and locations of the first dips in mid frequency ranges of the plates' SPL spectra.

讨论在振动板厚度、材料常数固定不变的情形下，藉由改变振动板长？i比及激振器尺寸，来找出第一个弯曲模态图中节线到振动板中心距离与中音谷声压落差值、位置之间的关系。

The submediant is the sixth degree of the scale and is midway between the subdominant or lower dominant and the tonic.

下中音是第六级音，在下属音和主音之间。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
