Soil salinization is a type of abiotic stress that affects the growth and development wheat. To explore QTLs related to salt tolerance during germination stage wheat reveal mechanisms tolerance, this study subjected 196 varieties (lines) from North China, East Central China stage. Principal component analysis was employed for comprehensive evaluation tolerance. Based on D value, research materials classified into five levels, which 64 exhibiting or higher were selected. Further, genome-wide...
Debris distribution and dielectric fluid flow within the machining gap in electrical discharge (EDM) are important factors related to stable precision machining. Hence understanding of debris removal process is essential improving EDM process.

Abstract A fully kinetic particle-in-cell study is conducted to investigate the ion acceleration mechanisms in an electron-driven magnetic nozzle. All five powers contributing axial energy of ions are derived and evaluated under different field strength inlet density profiles. Among them, electrothermal electromagnetic contributes over 98% total accelerating power. The dominating mechanism found be acceleration, covering two thirds power originate from four sources, among which major...
Erosion can influence cathode life, and is thus considered to be one of the main factors limiting application applied-field magnetoplasmadynamic thrusters.

Applied field magnetoplasmadynamic thrusters (AF-MPDTs) are one of the potential for high power space propulsion. However, anode deposition limits improvement in thruster’s efficiency. According to previous research studies, voltage drop is supposed be main factor AF-MPDTs without considering effect centrifugal force. Actually, force cannot neglected when magnetic high, where not only dominant deposition. Due significant force, there might no obvious shortage charge carriers near surface...
