Although the furnace tubes are usually designed for a normal life of 100,000 h, their actual service life varies from 30,000 to 180,000 h, which will be dependent on the service conditions and the quality of materials[1] The reformer tube investigated in this paper has been in service for 12 years ( about 100,000 hours) and reaches the design life.

Introduction Based on the physical is a science experiment.
“purpose”, will open the corresponding online teaching material.
The online teaching materials are shown by multimedia technologies, such as texts, pictures, diagrams, animation and sound.
Log on to a success, he can get his new password; get the key material operation experiment of experiment and the teacher's instructions.

However, commonly, there are limitations on reducing the thickness due to technical reasons related to the Surface Mounting Technology (SMT) for a PCB, material of the case, forming process, and assembly, and the paces of development of other technologies is slow.
For this study, a sheet metal of heat-treated SK5 steel was used as the material for fabricating the flat spring.
Generally, the hardness of raw SK5, which is a carbon tool steel, is only 170 ± 10 HV; however, the mechanical properties of the material can be controlled relatively easily by varying the heat treatment conditions in a process called austempering.
The material used to fabricate the spring wire rod is SUS301H, which is widely used for mobile phones, and the chemical composition is as shown in Table 3.

And then, the materials obtains elasticity.
Experimental Materials.Trimellitic anhydride,purchased from aladdin,was dried 6 hours under vacuum condition at 140˚C.Aminobenzoic acid(PABA),1,4-butanediol and benzoic acid were used as received, toluene and N,Ndimethylformamide(NMP) were dried with calcium hydride,distilled under reduced pressure, all these chemical reagents were purchased from Chengdu Kelong solvent plant.

Surmann [3] found that the machinability of the engineering materials has a strong dependency on cutter inclination angles.
Experimental details The workpiece material is H-13 steel which is widely used in die&mould industries because of its good mechanical and thermal properties.
The roughnesses in different scales are linked with machining process and material property closely.

When it comes to the end of the building, Completion shape draws, and then still wants to add a different material and colors are added to the different parts of the building.
If the operators want to assign a material for all windows, they can close all layers except window layer.
Add the material to all the windows after picking up suitable material thus the batch quantity handles raises efficiency.
