Abstract.
End-point carbon content is affected by various factors which are correlative more or less, which lead to the difficulties in valid analysis of smelting data. 10 input parameters have been determined by analysis of field data and the relationship between material balance and heat balance [7], furthermore, it also combined with practical production process in Steel Plant.

Abstract.
Materials and methods Groundwater characteristics.
SEM analysis (SEM Philips S-570) was used to observe the morphology of the filter materials, and the samples were prepared as biological samples, which were fixed with 2.5% (volume ratio) glutaraldehyde, and repeatedly rinsed with 0.1M phosphate buffer-sucrose solution, and then treated with OsO4(1% in 0.1mM phosphate buffer).

Abstract: The aqueous solution polymerization methods were carried out using microwave heating for the superabsorbent synthesis experiment.
Introduction Superabsorbent is a new type of functional polymer material.
The latter is thermal radiation from outside to inside using the external heat source by way of heat conduction, and microwave heating material is using the dissipation of body heat in electromagnetic field.

When scanning, the measuring head of contact measurement touches the part surface, so it has high accuracy but slow speed measurement, and it’s not suitable for soft materials.
While the non-contact measurement device does not touch the measured surface, has high speed and it’s suitable for all kinds of hard and soft materials.
