Starting from the state variable evolution equation nonlinear evolution equations of dynamic information entropy density and dynamic information density are derived, that describes respectively the evolution law of information entropy and information.
Finally, this papers puts forward the factors influencing Chinese in the middle school, analyzing in details the individual participating degree, accuracy of the purpose of classroom instruction, the density of information, the classroom psychological tension and the moderateness of the teaching rhythm, so as to promote the teachers to reflect there own teaching and think about the strategies to improve the effectiveness in Chinese teaching of the middle school.
The macro factors include the reliability and the density of information offered by academic journals, the running policy of the journal, the editor's ability to choose papers and scientific editing methods.
The data density of the near field optical recording is mainly determined by near field electromagnetic distribution of probe fiber such as transmission efficiency, near field light spot size, polarization keeping and the grade of the electromagnetic field.
Data density and its effect on the annual direct cost for the 2002 issues of Journal of South China University of Tropical Agriculture are analyzed, showing that the journal contains a lower data density and costs more than reasonable for the conveyance of each piece of technology data.
Using the chart of isochromatic region, the transformation between density and color which can be controlled will be achieved and the character- istic information-density of black-white image to be treated will be trans- formed to the color of pseudo-color image expected.
The great potential in vast parallelism computation and the extraordinary information density of DNA are displayed in DNASC to some degree.
Biosensors based on electronic conducting polymers appear particularly well suited to the requirements of modern biological analysis-multiparametric assays, high information density, and miniaturization.
Polymer materials show their impact on optical storage technology for developing high information density and fast access-type memories with a high read-out efficiency.
In addition, an information density matrix is constructed that indicates how well predicted data match observations.
Does the information density of amino acid composition increase
