., KE-1, L-64, TX-15, and EL-40.
EL-40 is castor oil polyoxyethylene ether.
Dynamic viscosity variations of TX-15 and EL-40 aqueous solutions are plotted in Fig. 1 (c) and Fig. 1 (d), respectively.
However, shear thinning effect can be seen for some conditions: KE-1 aqueous solution at 100℃, higher concentrations of L-64 at 75℃ and 100℃, TX-15 at 100℃, and EL-40 at 100℃.

China aZhouming@hit.edu.cn; bwyjwyj791120@126.com Keywords: SICP/Al Composites, High Speed Milling, Surface Defects, Micro-Topography Abstract: For the purpose of investigating the surface defects on the machined surface in high speed milling of SiCp/Al Composites, the high speed milling experiments were performed on the precision milling machine (ops650).The machined surface was observed and measured by the OLS3000 Confocal Laser Scanning Microscope.
The past research on the machined surface micro-topography of SiC/p Al composites are mainly concentrated on the surface roughness, micro- hardness, residual stress and the chip formation mechanism.
To investigate the surface defects is necessary to adequately characterize the machined surface of SiC/p Al composites.
In this paper, the types and formation mechanisms of machined surface defects of SiC/p Al composites are investigated.

HI (Eq. 7) [9] is a regulatory approach to component based mixture risk assessment which is based on the concept of CA, where EL is the exposure level, AL is the acceptable level.
Various measures for exposure levels and expectable levels may be applied; the only constraint is that EL and AL must be expressed in the same unit.
In contrast to the HI, however, exposure levels (EL) of chemicals in a mixture are not expressed as fractions of individually acceptable levels (AL) but as fractions of their respective points of departure (PODs) such as NOAELs or Benchmark concentrations or doses (BMD).

The study from Hill et al, 2007 proposed that tellurite glass possess a wide range of refractive indices which may be suitable for core clad structured fiber fabrication [1].
The advance properties of erbium ions had been proved by the previous study of El-Mallawany et al. on the optical properties of tellurite glass doped with erbium ions [3].
Azlan et al, 2013 used erbium nanoparticles to study the optical properties of zinc borotellurite glass system [5].
The refractive index and optical absorption were measured by using EL X-02C high precision Elipsometer and UV-1650PC UV-Vis Spectrophotometer (Shimadzu).
