Effect of Particle Size and Distribution of Rapidly Quenching NdFeB Magnetic Powder on Magnetic Properties of Polymer-Bonded NdFeB Permanent MagnetLiu Ying Tu Mingjing (Department of Metal Material, Sichuan University, Chengdu 610065, China)摘 要:PolymerbondedNdFeBpermanentmagnet,firstlyappearedin1980s,isanewtypeofpermanentmagneticcomposite......
positioning system (GPS) and interferometric synthetic aperture radar (InSAR) data were used to derive the coseismic slip distribution of the earthquake fault. Firstly, based on the homogeneous elastic... and 50.2° southwest-dipping. Secondly, fixing the optimal fault geometric parameters, the fault plane was extended and discretized into 16×16 patches, each with a size of 1 km×1 km, and the non-uniform......
size and arrangement determine both solid distribution in section and the moment of inertia. The larger the cell size is, the larger the moment of inertia J is, so if the elastic modulus is constant...

Consequently, for fracture core, the water-phase relative permeability is higher and the co-seepage interval is narrower than that of three......
performance between the solid surface and the particles. Key words: micro-particles; adhesion; glass surface; reagent film; size distribution 1 Introduction It is well known that a large number of micro... increased at high concentration of the reagent, and high concentration could promote the abilities of the slides surface to capture the larger particles. 2) By comparing the particle size distribution......
slurry segregation, the representation parameters of gradation, i.e., average grain diameter and particle size distribution index, were established based on the Fuller formula. Eleven types of gradation based on Weymouth gradation theory were used for segregation test to study the range of particle size distribution index. Solid materials from a certain mine in Yunnan Province were used......
; material structures were rather complicated, and structural planes were distributed in a disorderly manner. From the particle size distribution characteristics of the fractured rock masses, the block... J. Cent. South Univ. (2020) 27: 2849-2863 DOI: https://doi.org/10.1007/s11771-020-4514-8 Distribution patterns of rock mass displacement in deeply buried areas induced by active fault creep slip......
Efects of Washing and Drying on Crystal Structure and Pore Size Distribution(PSD) of Zn4O13C24H12 Framework(IRMOF-1)Mehrzad Arjmandi,Majid PakizehDepartment of Chemical Engineering, Faculty... to XRD test.The pore size distribution of samples 1-5 and 8 were calculated by SHN1 method and results showed that the samples in which solvent vacuum was DMF,have lower pore volume,uniform pore size......
because of the deoxygenation, cover cinder, chemical aliquation, etc, which is one of the most important topics during continuous casting although their quantity, size, shape, distribution...

Influence of size and distribution of W phase on strength and ductility of high strength Mg-5.1Zn-3.2Y-0.4Zr-0.4Ca alloy processed by indirect extrusionHansi Jiang1,Xiaoguang Qiao1,Chao Xu2,Shigeharu... and size of W phase. A higher fraction of DRXed grains is obtained due to the homogeneous distribution of micron-scale broken W phase particles in the alloy extruded at 400?C, which can lead to higher......
