Convergence and stability of an explicit method for direct integration of dynamic equation in case of negative-stiffness;

The selection of numerical integration method of precise direct integration is discussed in this paper.

To control the inter-storey displacement,this paper does systematic researches on response characteristics of storey-adding structure spanning existing building with steel frame under minor and major earthquake by using direct step-by-step integration method and investigates anti-seismic effect of storey-adding structures by means of friction energy-dissipation devices.

Improving accuracy of biochemical analyzer by uniforming integral time data

The relationship of IRFPA between response characteristic and incidence radiation,integral time was analyzed by using the practical response data.

The integral time process of tradition image sensor is quite troublesome,to realize the integral time online regulation,a image sensor system can be able to online regulate the integral time through SPI is designed.

This article introduces the parameters that influence the NETD of infrared push-broom systems,proves that the multiple sampling technology can remarkably reduce the NETD,and gives a principle of choosing integrating time and sampling times when the r.

Influence of integration time on IRFPA imaging system;
