The three-dimensional sound graph may show the relations among time、frequency and intensity,which can be selected to show in color or monochrome mode. A movable cursor is set up to select and show two-dimensional analysis graph of frequency and intensity at some time arbitrarily.

In this part, the concepts of equal-performance surface and equal- performance curve are given out and a new mathematics model of sophisticated performance appraisal is designed. At the same time, a useful number- diagram tool for performance analysis called "sophisticated performance analysis graph" is designed.

The paper first introduced some theories about network analysis, graph theory and geographic network modeling; Then this paper discussed the problem that how to express the road network in digital map;

Vehicle Routing Problem(abbr. VRP) was an important problem in recent years in the fields of Operational Research, Application Mathematics, Network Analysis, Graph Theory, Computer Applications, Traffic Transportation etc. It was derived from the field of Traffic Transportation and had widely applied to communication, production, national defense, biology etc.

Taking Tashan mine of Datong as example, based on the investigation ofcurrent situation of ecological environment, by means of RS, GIS and on-siteinspection, analogy analysis, graph measuring, expert consultation and patternforecasting combined together, the author did eco-environmental impact assessmentof coal-excavated subsidence of sienna knap area, and analyzed the influence of thesubsidence of the earth's surface on soil corrosion and land utilization, then theauthor put forward suggestions on land reclamation and ecological rehabilitation.

In order to grasp the urban system processes and evolution pattern of Hunan province comprehensively, this article has made further discussion on its structure characteristic: Through regression analysis, graph analysis and statistics analysis of the time series data and cross sections data, by combining with the fractal theory, we induce the following conclusion: the hierarchical size structure presents the law of the Primate City,the Rank-Size Rule and Pyramid Structure characteristic, but it also has the insufficient development problem of the high hierarchical size city.

The program,which is coded in C, puts time and frequency domain analysis, graph display and plotting together into one integral unit,capable of analyzing and studying any kinds of partial response.

Understanding systematic reviews: the meta-analysis graph (also called 'forest plot')

The analysis graph can be seen as a "recipe" for solving industrial applications, stating which kind of decisions have to be made at which stage.

Together with an object-specific description, the analysis graph is instantiated to perform the inspection.

This paper concentrates on a general analysis graph within a systematic automated visual inspection concept that speeds up the development of such systems by increasing the flexibility.

Increasing flexibility for automatic visual inspection: the general analysis graph

The data of density and abundanceof the plant species from three communities in Dinghu Shan forest were used as the ecological information for the pattern analysis and the association analysis. The four methods of pattern analysis, Greig-Smith's(1952) pattern analysis, Kershaw's (1970) intensity analysis, Hill's(1973)two-term local variance analysis, and spectral analysis, were applied to describe and indicate the population pattern of the tree, shrub species. The other...

The data of density and abundanceof the plant species from three communities in Dinghu Shan forest were used as the ecological information for the pattern analysis and the association analysis. The four methods of pattern analysis, Greig-Smith's(1952) pattern analysis, Kershaw's (1970) intensity analysis, Hill's(1973)two-term local variance analysis, and spectral analysis, were applied to describe and indicate the population pattern of the tree, shrub species. The other three methods of association analysis, joint analysis and covariance analysis(Kershaw, 1900), correlation analysis(Austin, 1968)were utilized to explore the interspecific association of the representative species in three communities. The comparisons between the methods that had been used were made in this paper. The pattern analysis are very useful for separating the intensity, scale and grain of the pattern and indicating the patchiness of horizontal dispersion of plant population. Of the four methods, the Greig-Smith's and the Hill's are appropriate for the utility in the lower subtropical forest, especialy being applied cooperatively. It had been found from the analysis graphs that Kershaw's not only has no suitable statistics-test but also reduces the peak values. The spectral analysis has some advantages of describing the pattern, but no enough evidence to prove its efficiency for a small number of the samples. The association analysis gave some interesting results from which the reasons of interspecific association could be deduced. The positive association is the fruit either of the similar responses of two species to the environmental factors or of the dominants pattern being exerted on another species. The negative association is the consequence either of the variant responses of two species to the environmental factors or of the automatic division of the horizontal spaces occupied by two high density species, The appearances of the association between plant species could not be restricted by the block size and the type of pattern. Among the three methods that had been used the joint analysis is the best one not only for its clear graph but also for its statistical significance. Doubulessly, all the analyzing methods used in this paper, have played the important role on the advance researches of the plant species space distribution, in particular, on showing the patchiness and the mosaic of the plant population individuals.

The purpose of the present study was to make a cross-sectional observation of the male's voice change process.The salivary testosterone was tested with the RIA method,which reflects the serum free testosterone level that has biologic effects.On the other hand,with more than 500 logarithm spec- trum,amplitude spectrum and autocorrelation analysis graphs,the fundamental frequencies (F_0) and the first formant frequencies (F-1) of the highest tone.the lowest tone and the speech of 54 boys from 9 to 20 years...

The purpose of the present study was to make a cross-sectional observation of the male's voice change process.The salivary testosterone was tested with the RIA method,which reflects the serum free testosterone level that has biologic effects.On the other hand,with more than 500 logarithm spec- trum,amplitude spectrum and autocorrelation analysis graphs,the fundamental frequencies (F_0) and the first formant frequencies (F-1) of the highest tone.the lowest tone and the speech of 54 boys from 9 to 20 years old were detected. Results showed that the increase of the testosterone during puberty may be the main cause of the male's voice mutation.The variations of F_1 suggested that there may be some changes in vocal track shap during puberty.There are different properties of F_1 between sing and speech.Besides,through synthesizing the results,evaluate was presented on the characteristics of the voice spectrums and the voice mutation process of the male teen-agers.

To describe the interactions among icons and their dynamic behaviors, a Petri net-based iconic programming system is presented. First, the formal definitions of 4 basic class icons are given. Second, the functions of system components are discussed and an algorithm to generate net analysis graph is designed. Finally, it is illustrated by an example how the system components (icon-library, knowledge-base, grammar-base, dynamic running-base, etc) cooperate during the iconic programming, code generation and...

To describe the interactions among icons and their dynamic behaviors, a Petri net-based iconic programming system is presented. First, the formal definitions of 4 basic class icons are given. Second, the functions of system components are discussed and an algorithm to generate net analysis graph is designed. Finally, it is illustrated by an example how the system components (icon-library, knowledge-base, grammar-base, dynamic running-base, etc) cooperate during the iconic programming, code generation and execution. A system prototyping supported by UNIX for SGI graphics workstation has been implemented. It is shown by preliminary experimental trials to this prototyping that no matter iconic programming or code execution, Petri net is more effective on the visualization programming than temporal logic.
