According to Palombarini et al. [14] boriding steels containing large amounts of chromium and nickel, lead to the formation of chromium and nickel borides on the treated surface.

Several routes were investigated especially in the polythiophene family which was described by Roncali and al. [4].

The great difference of constitutive behavior between bulk solder and ultra small FC solder joint given by Wiese et al. [3-4] actually has validated this suspicion.
Here, we assume the constitutive relation of the indented solder alloy can be expressed as elastic and power-law creep: m cr el crel εbεEσσσ && +=+= (1) where σ is stress, elε& is elastic strain rate, crε& is creep strain rate, E is Young's modulus, b and m are material constants.

Ruohu Zhang et al have reported Ag@SiO2 enhance fluorescence of Rose Bengal[11-13], but the study of Ag@SiO2 function on rare earth is rarely seen[14].
The determinations of C, H and N were performed by a Vario EL Cube elemental analysis instrument and the contents of rare-earth elements were obtained by EDTA titration.

SEM was used to test the distribution of MOS in ABS matrix,the results were seen follow Fig6,7. 0 10 20 30 40 50 60 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 E lon gat io n a t b re ak/ % MOS content/% Modified MOS Unmodified MOS 0 10 20 30 40 50 60 2 3 4 5 6 7 8 El as ti c mo dul us / MPa MOS content/% Modified-MOS Unmodified-MOS 10% 20% 30% 40% 50% 60% Fig.6 SEM photos of surface modified-MOS distribution in composites(×5000) 10% 20% 40% 60% Fig.7 SEM photos of unmodified-MOS distribution in composites(×5000) These photos show that the distibution of modified-MOS in composites is better than the unmodified one,the amount of whiskers agglomeration and butt ones is little.In the range
