Considering the surface roughness of piston ring and cylinder liner and deformation of cylinder liner, the friction dynamics calculation model of cylinder liner-piston ring friction pair was established.The effects of top ring, other piston rings and cylinder liner surface roughness on friction performance were analyzed by grouping comparison and B
We construct a new age-specific mortality framework and implement an exemplar (DLGC) that provides an excellent fit to data from various countries and across long time periods while also providing accurate mortality forecasts by projecting parameters with ARIMA models.The model parameters have clear and reasonable interpretations that, after fittin
The vast majority of research dedicated to enhancing the homogenous charge compression ignition (HCCI) low-temperature combustion system is focused on improving controllability, efficiency and emissions.This article aims to assess the impact of HCCI combustion on the operation of the piston Wi-Fi Wire ring system.Utilizing the measured pressures in
Abstract Bluetongue virus (BTV) VP7 is a group-specific protein that is highly conserved in different serotypes.In this study, BALB/c mice were immunized Crib with purified recombinant BTV-1 VP7 protein expressed in E.coli.Then six monoclonal antibodies (mAbs), 2A7, 2B2, 2B3, 2D3, 2D7, and 2H2, against the BTV-1 VP7 protein were produced using hybr
Because cryopreservation can effectively slow down the putrefaction and prolong the preservation time of corpses, it has become the main way of corpse preservation in Motor Brake China.However, it may cause a certain degree of non-specific effects on the corpses and thus interfere with forensic pathological identification.This paper summarizes rele
