FeCl3 which was a sublimate material was prejudiced to the graphitization of the needle coke.
Introduction Needle coke is one of the most important raw materials carbon industry ,because it has low coefficient of thermal expansion, and good graphitization performance.
This coke need to be further heated, in order to that various physical and chemical indexes and electric properties of needle coke are matched with the requirements of the graphite electrode materials [4].
The samples that were provided by the party big materials company of FuShun and been finished the hot polymerization were calcinated in 1000 ˚C, 1100 ˚C, 1200 ˚C, 1300 ˚C in airtight atmosphere for 1 h, 2 h, 3 h, then natural cooled, sampled, grounded to a powder for analysis.

This stare-shape target can be manufactured by micro milling for its process flexibility in producing different shapes of 3-dimensional features and a variety of materials [3].
The rake angle should be elected based on the workpiece material.
For instance, zero or positive rake angle is pleased for plastic material and some extent of negative rake angle is suitable for brittle material to realize plastic mode cutting.

Taken into consideration of the leakproofness of MRFs and the precision of data collection, in the relative shear mechanism of double channels, all the troughs and rotors of MRFs are produced by magnetism isolation materials such as bronze, among which the thickness of the upper and lower channels of MRFs is 1mm but the width of working area is.

In a motivation to search for new prospective magnetoresistance materials, substitution of Mn for Mo, both being 4d transition metals but with different electronic configurations (Mo5+~[Kr]4d1, Mn5+~[Kr]3d2), has been selected since there were few reports on Sr2FeMnO6.
Stoichiometric amounts of high purity raw materials SrCO3 (99.99%), Fe2O3 (99.99%), MnO2 (98%) were ground and calcined for 10 h at 950 ℃ in air.

Introduction Bentonite have been international selected as buffer/backfill material for high level nuclear waste repository due to its high adsorption, expansibility, low permeability and excellent thermal conductivity.
To be the engineered barriers between parent rock and high level radioactive waste packaging, buffer/fill materials need appropriate mechanical properties so that it can buffer effect on waste cans from surrounding rock pressure and effectively prevent radionuclides overflow from cracked waste tank when the disposal site have geological changes.
For example, GrahamJ, SaadatF and GrayM.N[1] have performed the drained and undrained Triaxial experiments on the mixtures of bentonite and sand, which provided available material parameters for numerical simulation of disposal repository, forecasted the variation of shear strength and deformation as the effective stress increasing under normal condition, and established formula of material strength and deformation in critical state.
High-pressure triaxial testing on the Canadian reference buffer material[J].

Additionally, the construction action and embankment materials disturb the original heat exchange between the underlying permafrost and ambient environment [1~3].
Based on the characteristic of heat transfer of embankment materials, the response of underlying permafrost between two framed embankments decreases and approximates to the permafrost underlying the natural ground when the distance is large enough.
Parameters for each material are shown in Table 1.
