Studies on the Relations between the Plant Stem of Wheat and the Field Transmittance;

The phase constitution,surface morphology as well as the ultraviolet-visible(UV-VIS)transmittance and bandgap of the films were investigated by means of X-ray diffractometry,scanning electron microscopy and UV-VIS spectropho- tometry.

The transmittance of samples was examined by an UV/VIS spectrophotometer.

The addition of nucleating agent into PP to improve it's clarity is expounded; the influence of different dosage on the transparence of the articles and the optimum dosage of other additives are studied, the optimized recipe of special PP compound is determined.

The filtration speed, the yield, DE value and transparence of sugar liquid from these two crafts were measured and analyzed.

With self-brewed golden silk date vinegar as raw material and transparence was mensurated by spectrophotometer method,different conditions of Chitosan on golden silk date vinegar\'s clarification technology were studied in this paper.

The transparent glass-ceramics were characterized by optical transmittance and field emission-environment scanning electron microscope(FE-ESEM).

The Study of Transmissivity and Zeta Potential for Waste Water from Flotation of Phosphate Ores;

The results showed that the transmissivity is at level of about 58% and that the main factors are ports, second phase and the size of grain boundaries.

XRD was used to investigate the relation between the crystal structure and thickness of ITO transparent conductive films deposited by DC magnetron sputtering process, and how the resistivity and transmissivity change with film thickness were measured.
