including reclamation and repair of components, rapid prototyping and coating [1, 2, 3].
Fig.1 Appearance of laser stabbed layer surface Fig.2 The appearance of laser scanning melted layer When the scanning speed is low, interacting time is long, and melting material melts fully, the melting liquid convects well in the melting pool, the effect of soakage is good, heat accumulates well in the melting pool, the process of solidification and chilling is relatively long, in the end, a high quality surface is gained.
On the contrary, at a high scanning speed, laser and material interacting time is short, so the laser energy gained by material per unit time is lower and the melting layer melts insufficiently, the effect of soakage of melting liquid and base material goes bad.

Introduction
The advancements in wide bandgap semiconductor materials and devices emphasize the importance of cost-effective electrical metrology with rapid feedback to pilot or manufacturing lines.
Already demonstrated CnCV applications encompass bare and passivated wafers of materials such as SiC, GaN, AlGaN, Ga2O3, and HEMT structures AlGaN/GaN [5].

The data shown in this figure is representative for
contacts formed on Al+ implanted materials under the conditions described in the previous section.
A comparison of Ti/AlNi/W contact performance to Ti/Ni2Si/W on the same Al+ implanted material was also studied.
A second motivating factor for the continued investigation of this system is the possibility for it to serve as an ohmic contact for both n- and p-type material.

Also, it can fill line for profile,create the filling line standard drawings and can also generate the bill of materials of the assemblies.
The purposes of the analysis are (1) the optimization design of the scheme (2) analysing the reasons of failures,looking for improving methods.The main steps of the Finite Element Analysis technology in the submarine self-propelled model are, (1)setting up the various attributes of the materials, (2)the definitions of the restraint and load, (3)finite element analysis and optimization to main position by application module.
Such problems include the replacement of parts and even the abandon of whole materials, followed by the decrease of design efficiency, the waste of cost and the delay of manufacture period.
