A field emission display (FED) and a fabrication method thereof are disclosed. A lower plate of the FED includes: a cathode electrode formed on the substrate; a diffusion blocking layer formed on the cathode electrode; a seed metal layer formed on the diffusion blocking layer; carbon nano-tubes (CNTs) grown as single crystals from the grains of the seed metal layer; a gate insulating layer formed on the substrate on which the cathode electrode, the diffusion blocking layer, and the seed metal layer are formed, in order to cover the CNTs; and a gate electrode formed on the gate insulating layer.

A programmable controller system is formed by connecting a personal computer having an aid device program module installed to serve as an aid device for development of control program to a programmable controller having password protect function. A hardware key storing a specified password code is detachably attached to the personal computer. The aid device program module checks whether or not software module with a function of certifying a hardware key exists and if it is found to exist, it is linked as a part of the aid device program module and the function of certifying the hardware key is caused to operate.

The invention relates to a method for state prediction and fault diagnosis of a photovoltaic power station. The method comprises the following steps: acquiring a maximum power point current and current meteorological data of a photovoltaic string; calculating a theoretical generating voltage and a theoretical generating current of the photovoltaic string according to the current meteorological data and factory factors of the photovoltaic string; calculating a real-time generating efficiency of the photovoltaic string according to the theoretical generating current and a real-time generating current of the photovoltaic string, and calculating a generating efficiency change rate of the photovoltaic string according to the real-time generating efficiency; and performing state prediction and fault diagnosis on the photovoltaic string according to the generating efficiency change rate and a preset data model. The method and the system improve the efficiency of the state prediction and fault diagnosis of the photovoltaic power station, and moreover, an additional investment is unnecessarily increased, and the cost is low.

The invention provides a mechanical device for massive cultivation of sea cucumbers. The technical problems that the existing sea cucumber cultivation device does not have overall consistency, the constant cleaning and the stability of growing environment of the sea cucumber are not take into consideration, large human cost and labor time are consumed, and the labor intensity is high are solved. The mechanical device comprises a culture pond, two parallel sliding rails arranged above the culture pond, a running rail capable of moving on the sliding rails and arranged between the two sliding rails, a lifting hook lifting mechanism capable of moving on the running rail and a human-simulated shaking mechanism located inside the culture pond. The lifting hook lifting mechanism can be connected with the human-simulated shaking mechanism. The mechanical device for massive cultivation of the sea cucumbers is designed according to production requirements of actual farmers and production processes, the constant cleaning and the stability of the growing environment of the sea cucumber are taken into consideration, the wavy stimulation time of the growing environment of the sea cucumber is reduced, the working time is reduced, the labor force is reduced, the labor cost and the impact of human factors are reduced, and the mechanical device enables the cultivation to be convenient and mechanized to be controlled conveniently.

The invention provides low-temperature-hot-stamped gold-stamped type tipping paper for cigarettes and a preparation method of the tipping paper. The low-temperature-hot-stamped gold-stamped type tipping paper for the cigarettes and the preparation method of the tipping paper are used for overcoming the disadvantages in existing high-temperature hot-stamping that the energy consumption is high, and that the rate of finished products is low and the cold hot-stamping effect is poor. The gold-stamped type tipping paper for the cigarettes, provided by the invention, is prepared through firstly printing environment-friendly alcohol-soluble white ink and printing ink on a base paper layer, then, additionally printing a layer of an adhesion-assisting glue material on the environment-friendly alcohol-soluble ink layer, then, carrying out low-temperature hot-stamping at the temperature of 85-100 DEG C, and carrying out laser boring, slitting and rewinding. According to the low-temperature-hot-stamped gold-stamped type tipping paper for the cigarettes, provided by the invention, an adhesion-assisting layer is additionally printed on the ink layer and has the functions of protecting the ink layer, enhancing the hydrophobicity of the ink layer and improving the adherence with a gold-stamped layer and the fastness of adhering of winding-adhesive glue, and special electrochemical aluminum hot-stamping foil for low-temperature hot-stamping is used in a matched manner, so that a low-temperature hot-stamping procedure can be completed at the temperature of 85-100 DEG C, and the energy consumption of a gold-stamping process is greatly lowered, and the service efficiency of a gold-stamping plate is increased, and thus the cost of gold-stamping is reduced.
