Confirmation of new photodetector and its fill factor;

The integration technique is applied to 256×256 PtSi CCD, and has made its fill factor increased by 2.

The results show that the performances of graded gravel mixture are improved significantly after being treated with cement and lime,especially when fill factor is 0.

Researches on filling coefficients for stability of soil stratum permeability;

Based on the comparison between theoretical calculation and test results,this paper suggests that the filling coefficient of c.

At present the cell array lens is usually cylinder or hemispheroid whose fill-factor(the ratio of light area and total area) can achieve about 90.

But at present the cell array lens is usually cylinder or hemispheroid, although the hexagons arrange is used, whose fill-factor (the ratio of light area a.

A full focusing filling factor is introduced.

The numerical method of the space-time conservation element and solution element(CE/SE) is deduced to simulate the interior flow of pulse detonation engine(PDE) with different filling coefficients.

Under same excess coefficient α,and various filling coefficients β,the detonation pressures are measured,and the factors influencing detonation pressures are analyzed.

In this paper, the packing factor of the coatings prepared by glancing angle deposition is analyzed under the conditions that the flux arrival angle of coating material is α and the columnar microstructure inclination angle of coatings is β.
