useful output
2.Abstract: In this paper?for real marine underwater noise data by using synchronous acquisition of points?inputs-output covariance matrix is obtained by filtering? compensating delay and crosscorrelation.Then the contribution of inputs to output in network sense and partial coherence as well as other useful quantities are calculated from the inputs-output covariance matrix.
6.Abstract: By using the correlation analysis of cotton climatic output and temperature elements of different temperature types and different length periods of time in Akesu cotton region, the results obtained indicate (1) using daily temperature elements of different length periods of time correlated with cotton climatic output is more useful, more reasonable and more easily in founding out optimum temperature elements with biological significance than using ten-days temperature elements; (2) In three temperature elements of mean temperature, maximum temperature and minimum temperature, the effect of maximum temperature on cotton climatic output is the greatest, mean temperature is greater, and minimum temperature is the least; (3) The low temperature in later spring and summer have some limiting effects on forming cotton climatic output in Akesu cotton region.
