Next, we will analyze the repair process, we know that if the material is in short, the maintenance will be delayed, and the entire work flow will be slowed down, it is the weak link in the course of their work.
Table2 The average time of the main processes  Process Prepare materials  Removable and washable motorcycle Assembly of  locomotive whole assembly Test days 5 5 4 5 3 From the table, we can see that it takes 22 days from preparation to delivery, in which the locomotive assembly period is about nine days.

As a solution to this problem, we developed an electrolytic re-insulation grinding method that finishes materials while applying a current between the material and the grinding wheel.
Recently, soft magnetic powder cores (SMPCs) have been drawing attention as materials for iron cores mentioned above [1].
Toroidal materials with an outer diameter of 34 mm, an inner diameter of 20 mm, and a thickness of 5 mm were used for the evaluation.

Multiple Phase Identification in Alkali Activated Slag by SEM-EDS Najat Alharbi1,a, Richard Hailstone2,b, Benjamin Varela3,c 1,2Center for Imaging Science, Rochester Institute of Technology, 54 Lomb Memorial Dr,.
The starting material, slag, is found to be a heterogeneous material with at least two phases.
Upon alkali activation the material becomes more heterogeneous, now exhibiting at least four phases with significant different chemical composition.
Two techniques were used to determine the nanostructure of the materials: scanning electron microscopy to acquire back scattered electron (BSE) images and EDS maps.

For the material physical systems, that simulate the dynamic behavior of equipments, industrial plants and constructions, the operation in resonance mode is unstable being characterized by pulse variations in the band-pass.
In this paper, the operating element of the vibrating equipment is modeled as an one-degree-of-freedom system, with mass m and with the viscoelastic links k,c specific to the external medium (material) with which the operating element comes into contact for the required operating process.

Introduction Zinc oxide (ZnO) is one of the most important II–VI group wide band-gap semiconducting materials which have many promising applications such as, optoelectronic devices, field emitters, solar cells, and sensors[1-6].
Besides temperature, the concentration of the Zn(NO3)2×6H2O electrolyte solution plays a crucial role in building these novel self-assembled nanostructure materials.
