The duration of limited inductive photoperiod is 13 week

The periodic boundary condition is constructed with Floquet theorem.

The conservative form and singular perturbed ordinary differential equation with periodic boundary value problem were studied, and a conservative difference scheme was constructed.

This paper, considers conservative equation with periodic boundary value problem, and construct a difference scheme, Uses the method of decomposing the singular term from its solution and combining an asymptotic expansion of the equation, proves that the scheme converges uniformly to the solution of differential equation with order one.

Theoretical analysis for microbend critical period of optical fibers;

Micro-bend optical fiber sensors are analyzed by use of the light ray tracing that the micro-bend critical period of optical fiber sensor is the space repeat distances within the fiber, through which light ray transmits at the maximum incident angle, and the result is coincident with the couple made theory analysis and experimental results.

A discrete certainty inventory model in a limited period is constructed without considering inventory lacking.

In this paper,a class of discrete deterministic zero lead time economic order quantity(EOQ) inventory models with limited period is studied.

In the algorithm the length of scheduling period is adjusted according to the residual system resources and the variable range of period tolerance.
