核心提示：摘要目前在我国各地型水面舰船上都配备了航煤气体报警仪，气体浓度传感器采用的是传统的4-20mA模拟信号的模式传送气体浓度值，只好每个检测通道配备一块具有检测报警及浓度值显示功能的检测板，随着气体浓度检测通道数目的不同配备不同数量的通道板，但大型舰船通道的数目比较多，因此报警系统体积会变得十分庞大，不利于操作人员使用，而且传统的4-20mA电流环传输信号，不利于长距离传输，容易带来干扰。为了巡检的需要，需要将其改造成现场智能仪表，通过将传感器检测结果

With analysing the the fatigue mechanism, the general mode of interply fatigue damage propagation is denoted by delamination length and crack density. Based on the power-law, the relationship between number of cycles and delamination length and crack density are established. The specimen is modeled as an equivalent six-ply material system. Starting with the analysis of interply stress, the interply shear stress under cyclic loading is calculated by using nonlinear three-demension FEA. According to the stage regularity of fatigue damage propagation, such models as average strain, effective modulus, ratio of delamination length and crack density, experimental relationship between crack density and effective modulus, are proposed by introducing subsection coefficient.

In this paper, we study characterizations of admissible in the general linear model Y, Xβ,ε|ε～(0,σ~2∑. We demonstrate that an admissible linear estimator is as the conditional generalized ridge-type estimation in the no constraint, equality constraint, inequality constraint general linear model.
