Cucumber downy mildew is a kind of disease which spreads very fast and isdangerous, in order to prevent the disease, peoplealways spray plenty of pesticides indiscriminately. Accurate assessment of the level of cucumber downy mildew is very important to the disease prevention and control. In a cucumber growing season, this paper collected the typical cucumber downy mildew leaf samples, and developed...
Ball-milled magnesium hydride with titanium hydride as a catalytic additive has been demonstrated to have excellent hydrogenation and dehydrogenation kinetics in recent studies, and is considered to be a promising material for hydrogen storage and thermal energy storage applications. The present work investigated the hydrogenation kinetics of this material across a wide temperature range, from room...
The most effective algorithms of solving large sparse linear system are Block Wiedemann and Block Lanczos, sparse matrix-vector multiplication iterations is the main process of these algorithms, to achieve parallel computing of its process, we have established three different parallel algorithm models and analyzed the characteristic features of their computing and communication, and through the analysis...
