摘要:A subgroup K of G is M p -supplemented in G if there exists a subgroup B of G such that G = KB and TB < G for every maximal subgroup T of K with | K : T | = p α. We study the structure of the chief factor of G by using M p -supplemented sub...

摘要:A subgroup H of a finite group G is called ℳ-supplemented in G if there exists a subgroup B of G such that G = HB and H 1 B is a proper subgroup of G for every maximal subgroup H 1 of H. The main aim of our investigation is to study the influence of ℳ-s...

摘要:Frozen ground has an important role in regional hydrological cycles and ecosystems, particularly on the Qinghai–Tibetan Plateau (QTP), which is characterized by high elevations and a dry climate. This study modified a distributed, physically based hydrological model and appl...

摘要:Halo evolution of an Al-17.5Si alloy surface after treatment with increasing pulse numbers of a high-current pulsed electron beam (HCPEB) was investigated. A halo is a ring microstructure resembling a bull’s eye. SEM results indicate that the nanocrystallization of halo indu...

摘要:The effects of nitrogen and straw management on global warming potential(GWP) and greenhouse gas intensity (GHGI) in a winter wheat–summer maizedouble-cropping system on the North China Plain were investigated. Wemeasured nitrous oxide (N2O) emissions and studied ...

摘要:Abstract(#br)Graphene oxide (GO) and polyhedral oligomeric silsesquioxane (POSS) grafted carbon fiber (CF) was demonstrated to reinforce the mechanical properties of fiber composites. Such a fiber composite was prepared by grafting POSS onto the CF surface using GO as the linkage...

摘要:Abstract(#br)A subgroup K of G is M p -supplemented in G if there exists a subgroup B of G such that G = KB and TB < G for every maximal subgroup T of K with | K : T | = p α . In this paper we prove the following: Let p be a prime divisor of | G | and...
