At this time can make a straight line through El and Er and calculate deflexion angle of face in the plane according to the straight line’s slant angle, the calculation of deflexion angle θXOY is shown in formula 4
If make projection to head, then there will be an approximate circle projection in XOZ plane, which is shown in Figure 5 (b), suppose that the distance from left and right pupils center El and Er to camera plane is del and der, we can find whether the face has left and right deflexion according to the two values.
At this time, make a straight line through two points of El and Er.

Wang et al. [5] directly determined diffusion coefficients for BH4 anions in 2M NaOH at temperatures ranging from 20 to 60 ºC, and described the temperature dependence of D (in cm2s-1) by the expression: D = 5.57 x 10-3 exp (-15.2 kJ / RT) (4) Adopting these data, we deduced the following D values for our working temperatures in 2M NaOH solutions: Temperature / ºC 25 35 40 45 55 Diffusion coefficient / 10 -5 cm2s-1 1.21 1.48 1.62 1.78 2.12 Using these D values from the chronoamperometric studies of Wang et al., we calculated n = 8.4; 9.6; and 9.6 for 0.03M NaBH4 solutions at 25, 40 and 55 ºC, respectively.

Alam et al deposited TiO2 thin films on silicon and glass substrates via the sol-gel process using titanium iso-propoxide [12], and reported that the cristallized TiO2 with an anatase structure is obtained after annealing at above 400°C.
The refractive index of TiO2 layers were measured with a DRE (EL X-02C) ellipsometer.
The refractive index of the prepared TiO2 thin films was measured with DRE (EL X-02C) ellipsometer.
R.Mechiakh et al [17] correlated this result to the densification of the film and pore destruction during different temperatures treatment.

The effect of a trace amount of Al on these synthesis processes was examined.
The purity of the sintered Ti3SiC2 bulk was remarkably increased by addition of a small amount of Al.
Addition of 0.1mol Al remarkably decreased the strength of TiC peak.
However, further increasing Al to 0.3mol resulted in an increase in TiC content.

In order to assess the effect of curing method on performance of AAS concrete, El-Hassan et al. [4] activated slag using grade N soldium silicate, also known as water glass (GW), combined with sodium hydroxide (NaOH) solution.
Shi et al. [6] investigated alkali-silica reaction (ASR) of AAS mortars activated used NaOH.
El-Hassan and Shehab [4] noted that intermitted curing of AAS concrete produced higher compressive strength after 28-days of curing compared to air curing and continuous curing under water.

Introduction Self-assembly synthesis of metal nano-particles has attracted great interest due to its unique properties and potential applications, especially in biotechnology, catalysis, magnetic, optoelectronics et al. [1-4].
Kim et al. [9], the size of nano-particles could be adjust by calcinated temperature.
Third, the minimum particle size would be limited by the size dependent energy, as the theory of Leff et al. which discussed about the size of Au nano clusters formed by thiol capped Au atoms is limited in a range [13].
