A mechanic-electric analogous method on rotational degree of freedom is used to establish the analogous circuit for moment actuator and its calibration system. The correctness for the analogous circuit is proved by some experiments. The result in this paper provides an useful basis for the optimization of the design of the moment actuator.

An advanced signal processing technique, higher-order spectra, is proposed to in vestigate the nonlinear coupling phenomena of the heart sounds. To extract more higher-order information of the heart sounds, a non-Gaussian AR model is selected for parametric bispectral estimation in analyzing several kinds of heart sounds. The non-Gaussian AR model of the sound signals is llsed to detect quadratic nonlinear interactions and to classify two patterns of heart sounds in terms of the parametric bispectral estimate. The bispectral cross-correlation is employed to the order determination of the model. Several real heart sound data are imple mented to show that the quadratic nonlinearity exist in both normal and clinical heart *** was found that bispectral techniques are effective and useful tools in analyzing heart sounds and other acoustical signals

It is increasingly recognized that machines and other vibrational sources can impart structure-borne sound power into supporting and connected structures through rotational components of excitation as well as translational components. It is well known that the rotational components are difficult to cstimate since moments are not easy to generate and measure. In this paper a prototype moment actuator is discussed. It consists of two parallel rods of giant magnctostrictive matcrial. The performance of the actuator has been investigated by means of a transfer function involving magnitude and phase. A quantity, 'purity of moment excitation', has been proposed to estimate the ability of the actuator to impart moments.

土壤污染具有一定的地域性,调查江门地区的土壤和蔬菜中的污染情况,科学指导菜农对蔬菜的种植。采用直接在本地采集土壤和蔬菜作为样品的方法,利用火焰-原子吸收分光光度法检测Cd、Cr和Pb三种重金属含量。结果表明:该地区的土壤中Cd、Cr和Pb的大部分检测结果都符合国家标准,只有镉测定项目的两个结果的污染指数污染(Pi)值大于1,有轻微污染的情况;在四种菜叶类蔬菜中,菜心的重金属含量最低,都没有超出国家一级标准的规定含量,而西洋菜平均含量恰好相反,三种重金属浓度都偏高,对。
