The data displays when TiO2 couples with PbS the particle diameter will increase, whereas when added Boron and Nitrogen ions into PbS/TiO2 combination, the diameter of PbS/B/N/TiO2 also decreases corresponding to PbS/TiO2.

But few accurate test and data support about this relativity has been reported in literature presently.
Therefore, the changing rule of diameters of all level vessels, caused by blood stasis or blood deficiency syndrome, can be described with the diameter of root vessel and reduction rate of vessel diameter.

Introduction
The functional tolerancing of mechanisms has now become well accepted in industry since this approach contributes to a reduction of manufacturing costs while improving product quality [1].
The functional requirement is thus expressed by the acceptable limits of an ending geometric entity related to another or to a datum reference system built from several geometric entities of the mechanism.
For a position tolerance of the cylinder axis related to a datum reference system (Fig. 2), the tolerance zone is a cylinder of diameter t, the deviation torsor comprises four components: D={tx, ty, 0; rx, ry, 0}.

Because of the similarity of structures for many power plants, the proposed optimization method can be expected to play an important role in the reduction of construction costs by power plants in the future.
As can be seen from the data above, PSE method can extremely achieve a better dynamic optimization design as well as decrease the iterations cost by the whole optimization procedure.

In the present work, five underwater nozzles with different structures are introduced to obtain the most optimum method for noise reduction.
The experimental data indicates that the elliptical nozzle can effectively decrease the noise of submerged gas jet at the same flow rate.

At present, selective catalytic reduction (SCR) of NOx with ammonia(NH3)is one of the most efficient methods for removing nitrogen oxides emissions in the exhaust gas from stationary sources to meet stringent emission regulations[1,2].
The optimal preparation condition of catalysts was normally obtained through comparing mass experimental data as the action factors were complex and variable.

Load, deflection and strain measurements were recorded by means of an automatic data acquisition system.
It could be seen that at initial loading stage, the load with deflection response at load point was linear and elastic, then the behavior became nonlinear after concrete cracked at a certain load, and the curves showed a reduction in stiffness.

Fig. 1.
While the number of cracks goes up, maximum deflection of midpoint increase which is because of reduction in beam’s stiffness.
