Both java applet and flash were applied to emulate virtual panel of multi-channel pulse height analyzer (MCA), and Microsoft IE browser was used to control MCA through internet to measure the γ-ray energy spectrum of 137Cs. It Was shown that most of the work completed by applet can be done by flash too, and with flash, more beautiful panel of the remote controlled instruments can be easily designed.

A specific digital time correlative accumulation has been developed. It is an adaptable scheme of signal processing for underwater acoustic technology used in telemetry, telecontrol and some remote sensing. Its basic principle is here introduced and the prospects for successful use in an acoustic channel with multipath, time-space variables and high noise level are amply discussed. The performances of this scheme are *** digital time auto-correlative accumulation has been used in two types of acoustic releases, and the cross-correlative accumulation has been used in a shallow water targets telemeter. There are some advantageous performances with these devices, for example, the effective range of release can reach about 4 nautical miles in a much complex shallow water area such as that in xiamen Harbor where the depth ranges from 3 to 30 m, and the targets telemeter can normally keep working in even shallower water area.

IT is well known that it is impossible to construct an integral representation of holomorphic functions with holomorphic kernel for the general bounded domain. In this note we establish a global integral formula of Bochner-Martinelli type with discrete holomorphic kernels; this formula may be applied to solving (?)-equation and singular integral equations.

A horizontal (?)-Laplacian is defined on strongly pseudoconvex complex Finsler manifolds, first for functions and then for horizontal differential forms of type (p,q). The principal part of the (?)-Laplacian is computed in local coordinates. As an application, the (?)-Laplacian on strongly Kahler Finsler manifold is obtained explicitly in terms of the horizontal covariant derivatives of the Chern-Finsler conncetion.

Carvalho, Lucchesi and Murty proved that any 1-extendable graph G different from K2 and C2n has at least A（G） edge-disjoint removable ears, and any brick G distinct from K4 and C6 has at least A（G） - 2 removable edges, where A（G） denotes the maximum degree of G. In this paper, we improve the lower bounds for numbers of removable ears and removable edges of 1-extendable graphs. It is proved that any 1-extendable graph G different from K2 and C2n has at least x′（G） edge-disjoint removable ears, and any brick G distinct from Ka and Ce has at least x′（G） - 2 removable edges, where x′（G） denotes the edge-chromatic number of G. Key words 1-extendable graphs, removable ear, removable edge.

In this article, distributions of internal stress and internal electric fields around a triple point of ferroelectric polycrystals generated by the spontaneous deformation and spontaneous polarization were investigated. It was found that when all three grains consist of a single domain, the internal stresses and the internal electric fields do not vanish. Though it may be determined according to the principle of energy, the spontaneous configuration will not be unique without involving other conditions due to the symmetry of the crystal structure.
