The paper properties such as roughness, gloss, surface wettability and other factors have great influence on the dot reproduction attributes of presswork, and different paper factor has different effect weight on the dot reproduction. The main purpose of this paper is to provide a new method to analyze the influence of paper properties on the dot reproduction. The method is to apply the grey relational analysis to analyze the influence law and the effect weight of paper factors on the dot reproduction during inkjet printing, which could provide theoretical guidance for improving the printability of paper. The grey relational analysis is a multi-factor statistical analysis method, which is based on the sample data and the grey incidence of various factors and is used to describe the strength, size and the order of the relationship between the factors. In this experiment, five types of inkjet printing paper were used to test their printing performance, and then the dot gain data were dealt with by the grey relational analysis method. Results showed that paper properties had a great influence on ink setting. Ink drop diffused and deformed less and dot gain was small when paper had smooth surface. According to the correlation coefficient degree of paper properties which influence on the dot gain of inkjet printing, the sequence was whiteness, roughness, surface wettability and gloss. Whiteness and roughness could significantly influence dot gain, followed by surface wettability, and gloss with minimal impact. Experiment indicated that the grey relational analysis was a simple and effective tool to analyze the influence of paper properties on the dot reproduction of presswork.

To assess the oil-paper insulation of transformer, it is necessary to establish the equivalent circuit for it regardless of using the time domain methods or frequency domain methods. Based on the principle of dielectric polarization, the extended Debye model is always adopted for the equivalent circuit of oil-paper insulation in transformer in most cases; however, it is usually difficult to determine the number of relaxation mechanisms in the model. This paper presents a method to determine it by the time domain dielectric spectra, namely, conduct differential operation for the depolarizing current of transformer’s oil-paper insulation to obtain the time domain dielectric spectra, and the number of spectrum peaks is equal to that of relaxation mechanisms. Thereby, the extended Debye model of the equivalent circuit of the oil-paper insulation of transformer can be built. This paper describes the analytical procedures of the time domain dielectric spectra method in detail and presents examples to validate its feasibility and rationality in determining the equivalent circuit model of transformer’s oil-paper insulation.

Soil suction is one of the most important parameters for unsaturated soils. An experimental program was carried out to measure the maric suction of soil specimens of a residual soil in Xiamen by filter paper method. Initial water content, soil structure, and stress state were taken into account to investigate the hysteresis loop of SWCC. The air-entry value of test soil is about 140kPa and residual saturation is about 18%. The soil specimen at wet of optimum has the largest hysteresis loop for a relatively uniform pore-size distribution. However, the soil specimen at dry of optimum has the smallest hysteresis loop. The soil specimen at optimum lies between them. For specimens subjected to different stress states under various applied loads, the higher the applied load on the specimen, the smaller the size of hysteresis loop. In drying or wetting process, there is a significant difference in matric suction though soil specimens are at same water content. Therefore, for this kind of soil, it should be attention that the shear strength may be greatly reduced during rainstorms.

This study describes a new precise recycle module as a clean poduction pocess and an environmental protection consideration that uses micro electroetching (MECE) and a new design of an intercross tool to remove defective transparent conducting oxide (TCO) nanostructures from the optical PET diaphragm surfaces for e-paper surface. This process takes very little time to remove the TCO easily and cleanly and is highly efficient both technically and economically. A large diameter of the cathode of the intercross tool combined with a small gap between the cathode and the workpiece corresponds to a higher removal rate of TCO. This higher feed rate combined with enough voltage results in a shorter machining time. A high rotational speed of the intercross tool can also improve dregs discharge and allows a higher feed rate of the optical PET. A small end radius of the cathode or a thin cathode of the bulge-form tool takes less time for the same amount (20 nm) of TCO removal.
