A method for determining the combination of the electrode and organic semiconductor with improved electron injection efficiency and hole injection efficiency in an organic TFT is provided, two types of FETS, that is, an n channel FET and a p channel FET are realized, and further, a complementary TFT (CTFT) is provided. The method for obtaining the vacuum level shift at the electrode metal / organic semiconductor interface from physical constants of constituent elements of the electrode and the organic semiconductor is provided. By changing the electrode metal through an electrochemical method, the electrodes whose electron injection and hole injection can be controlled are formed. By using these electrodes, two types of FETs such as an n channel FET and a p channel FET are realized, thereby providing a complementary TFT (CTFT).

The invention relates to a physical constant temperature seat, which is composed of a seat frame and a physical constant temperature chair cushion, the physical constant temperature chair cushion is assembled with the seat frame, and the physical constant temperature chair cushion includes a mask bag and a cushion layer, wherein: the cushion layer is composed of A constant temperature body, a heat insulation layer and a protective layer are formed. A heat insulation layer is arranged under the constant temperature body. The protective layer wraps and connects the heat insulation layer with the surroundings of the constant temperature body. The mask bag seals the cushion layer in the mask bag. The packaging bag of the constant temperature body is a closed bag of high-strength material that is breathable and leak-proof. It is divided into 4-13 strip bags by 3-12 partitions, and the strip bags are filled with energy storage materials. The energy storage material is composed of Glauber's salt, sodium bicarbonate, sodium bicarbonate, sodium carboxymethyl cellulose and distilled water. When the human body touches the constant temperature body, the energy storage material absorbs heat and undergoes a phase transition and melts. After leaving, it dissipates heat and returns to a solid state. The invention is safe to use, has no pollution, does not require additional energy, and is durable.

The invention discloses a four-in-one authentication method. According to the invention, four methods which are visual observation, color matching, microscopic observation, and volume weight comparison are integrated into a whole antique authentication method. In the volume weight comparison step, the volume weight of the antique requiring authentication is measured, and is compared with the volume weight of a contrast sample, such that the age of the antique requiring authentication is determined. According to the invention, the age and authenticity of an antique is determined according to inherent physical constants of the antique. A traditional authentication method is combined with the color matching, microscopic observation, and volume weight comparison methods, such that influences on antique authentication caused by human factors can be reduced. According to the invention, a standardized antique authentication method with high operability is provided. The method employs less equipment, and is simple and feasible. The method can be used in authentications of chinaware, jade articles and bronze vessels.

An improved device for measuring air specific heat ratio through adopting the vibration method relates to measurement of physical constants and aims to overcome problems existing in the conventional technology. The technical scheme is as follows: the improved device for measuring air specific heat ratio through adopting the vibration method comprises a glass tube and a vibration object, wherein the distance between the surface of the vibration object and the glass tube in the corresponding position can reach to 0.01-0.02 mm; small holes are formed in the side surface of the glass tube; the device is characterized in that the vibration object is improved from a steel ball to a cylinder; two or more protruding edges are symmetrically distributed on the side surface of the cylinder; all axes of the protruding edges are parallel to the central axis of the cylinder; grooves are formed in the glass tube; the number of the grooves is consistent with that of the protruding edges on the side surface of the cylinder; the cylinder can only be embedded into the glass tube grooves to slide upwards and downwards through the protruding edges; multiple circles and rows of the small holes are formed. The improved device has the benefits that the cylinder is prevented from rotating in the vertical direction; the protruding edges of the cylinder are matched with the grooves of the glass tube, so that rotation of the cylinder in the horizontal plane is avoided; owing to a larger gap between the cylinder and the glass tube, the flow manner of air is more close to laminar flow, so that collision between the steel ball and the wall of the glass tube is reduced.

The invention discloses a production method of constant-temperature oil preparation by using camellia oleifera seeds and refining purification. Physical constant-temperature press is carried out by using a double-screw oil press, and the oil preparation method is carried out by directly pressing oil materials without the process of steaming, stir-frying and the like; oil prepared by low-temperature pressing retains most of physiologically active substances in camellia oleifera seeds; high-temperature pressing is needed in a conventional pressing technology, and materials need to be heated fromroom temperature to 110-120 DEG C; according to the invention, a green constant-temperature oil preparing and processing technology is adopted, materials only need to be heated to 60 DEGC, and the steam consumption of the conventional technology is three times of the steam consumption of the technology provided by the invention according to calculation; steam is used only at a dry place with a low temperature in the green constant-temperature oil preparing and processing technology, and indirect steam is used, so that the oil preparing equipment is superior to the oil preparing equipment of the conventional pressing technology in all aspects such as service life and the like; the economic benefits such as energy conservation, environment friendliness and the like are very significant, thecamellia oleifera seed oil has better edible value and utilizing and developing values; the constant-temperature oil preparation and refining purification processing technologies are adopted, so thatthe obtained camellia oleifera seed oil has the advantages of light color, stable oil quality, original color and original taste, and retains the original characteristics of camellia oleifera seed oil. The method provided by the invention mainly avoids the defects of dark color and poor quality of camellia oleifera seed oil caused by high temperature in the processing process.
