A method to measure the resonant frequencies of sound in cylindrical and conical hollow is presented.

提出一种测量圆柱和圆锥状空腔声共振频率的方法，由微机和信号处理板配合构成的系统完成频响曲线的测量和运算，实验得到的数据和理论计算值相吻

For acetic acid,propionic acid and butyric acid with reducing of the inductive effect and increasing of the cavity effect,the apparent adsorption rated constant(k),the interaction energy between the absorbent and the absorbate and the affinity of the absorbate to the absor.

实验结果表明:乙酸、丙酸和正丁酸,吸附速率常数k随着吸附质浓度的增大而逐渐减小;对乙酸、丙酸和正丁酸,因为诱导效应的减小和空腔效应的增大,表观吸附速率常数k是逐渐减小的;吸附质与吸附剂之间的相互作用能逐渐减小;吸附质对吸附剂的亲和能也逐渐减小。

The article introduced the visible emissivity and opening phenomena ——cavity effect which makes the emissivity and the absorptivity increa.

这种由于辐射在空腔内多次反射和吸收使表面吸收率和表面发射率都增大的现象称之为"空腔效应"。

This characteristics of the cavity is so called cavity effect.

由辐射性能一致的漫射表面组成的腔体,在温度一致的条件下,其辐射行为可以归结到由腔体开口的表现来描写,这就是所谓空腔效应。
