In this paper we investigate the researching state, the developing situation and the prospect for the summability , the strong summability and their relevant approximating oder , strong approximating oder of Cesdro mean - an important linear summation process of the Fourier - Laplace series of functions on sphere.

The saturationproblem of an operator sequence of a kind of strong summability is discussed.

The LP approximation by strong summability of Fourier-Laplace series of a function defined on unit sphere is discussed.

Application of Residue Theory in Summation Series;

The convergence and summation of equispaced alternating series;

On basis of the results of reference, in this paper, the author got the summation formula of several basic bypergeometric series.

A discussion on designing the sum-circuit with just one operational amplifier;

This paper obtains the sum formula about a type of sequence of number through Able theorem.

It can be used in obtaining the sum of some number sequence.

According to the traffic signal theory,minutely analyzing vehicles queuing up on stop line,and presetting the traffic flux function of no crowd junction,and defining the value district of signal period and green to signal,so the concept of traffic demand intensity and relative demand intensity is put forward and considered as the standard of traffic management in junctions.

Using the idea and method of queuing theory, the stochastic inventory model is established presented in form of state probability for one sort of time_effective products, in which the supply intensity is constant but to be determined, the demand intensity is known already, but the demanding amount is stochastic.

And then based on it,the relationship among the market demand,product design and commercializing is discussed,and a model of demand intensity is established.
