Frey and Messenger (1973) and Guy,Chou, Lin, and Christen- sen (1975) confirmed that a microwavepulse with a slow rise time is INeffective in producing an auditoryresponse; only if the rise time is SHORT, resulting in effect in asquare wave with respect to the leading edge of the envelope ofradiated radio-frequency energy, does the auditory responseoccur.

1973，1975年这些人FREY， AND MESSENGER，CHOU， LIN， CHRISTEN－SEN确认，缓慢增加的微波脉冲不会引起听觉反映，只有增强时间非常短暂，以至影响了辐射射频边缘，才会导致听觉反应。

For the saturated aromatic aldehydes with malononitrile and barbituric acidit, the reaction was found to proceed very efficiently at room temperature giving excellent yields under ultrasonic irradiation, while for α,β-unsaturated aldehydes as well as p-phthalaldehyde with malononitrile and barbituric acid the reaction also proceeded smoothly at room temperature with good yields.

The computation analysis indicates that increasing the aperture of the concave focusing transducer, decreasing it's geometric focal length or raising it's central working frequency can improve the transverse and axial resolutions of the system simultaneously, but changing the dividing proportion of the transducer affects the two kinds of resolution differently. On compromisingly considering several factors including the exciting mode, the focusing ability and the radiation force effect, the concave focusing transducer should be divided into two equal-area parts.

计算研究表明：增大凹球面换能器的口径、减小几何焦距和提高中心频率均可以提高系统的侧向分辨率和轴向分辨率；但改变凹球面换能器的分割比例对两种分辨率影响不尽相同综合考虑超声换能器激励、聚焦性能以及产生的辐射力效果等因素，则换能器应按等辐射面积原则分割为宜。
