The present invention discloses a clinical specimen sampler, including a filtering device; and a sampling device. The sampling device includes a sampling adsorber and a rod. The sampling adsorber is connected with one end of the rod, and the sampling adsorber is encompassed in the filtering device. The sampling adsorber is utilized to absorb the body fluid secreted by the intima of an organ, and the filtering device is employed to prevent the mucosal tissue of the intima of the organ from entering the sampling adsorber and enable the body fluid secreted by the intima of the organ to enter the sampling adsorber, so as to be absorbed by the sampling adsorber.

A method is provided for authenticating micro-processor cards to determine whether a card is a genuine card or a fake card. Authentication is performed by a checking program of at least one card reader terminal. The program sends to each card commands belonging to a standard and public set of commands. The method includes: modifying the checking program in the terminal or terminals, in such a way that the program additionally sends, to each card to be authenticated, at least one additional command, called a secret command, from a set of at least one additional command, pre-inserted into each genuine card, and different from the standard and public set of commands; and a step of detecting authenticity of the card, if the secret command is recognised and / or processed correctly, or the presence of a clone, if the secret command is not recognised and / or is processed wrongly.

The invention discloses a system and method for superimposing rail temperature and beam temperature state temperature and video of a high-speed railway, which is suitable for use in high-speed railways. Firstly, the rail temperature and beam temperature are measured by wireless temperature sensor, and the temperature information is stored in the character storage module wirelessly to complete the serial communication between the character storage module and the video character superimposition module; the monitoring camera is used, and the synchronization signal is separated by the synchronization signal separation circuit. It is a line synchronization signal and a field synchronization signal, and at the same time, the video signal is amplified by the amplifying buffer circuit and transmitted to the video character superimposing module. Superimpose, and transmit the video and character superimposition to the display module for superimposition display. It is based on the superposition of digital signals, the superposition effect is flexible, and it has strong programmability and expansibility, which can realize more precise superposition control according to product requirements.

The invention discloses a method for adjusting negative temperature coefficients of constant current source. The method for adjusting the negative temperature coefficients of the constant current source includes that input voltage V = alpha V BE - V ref is set; the input voltage is added to a resistor to convert to output current I out of the constant current source to obtain a temperature coefficient of the constant current source, wherein V BE is PN junction forward conduction voltage drop of a triode, 1 / V BE * alpha V BE / alpha T is a negative temperature coefficient of the PN junction voltage drop VBE, alpha is a constant, V ref is reference voltage, and T is a temperature; and values of the constant alpha and or values of the reference voltage V ref are selected and set to enable the constant current source to obtain k times negative temperature coefficient of PN junction of the triode to achieve adjustment of the negative temperature coefficients of the constant current source. The invention discloses the constant current source utilizing the method for adjusting the negative temperature coefficients of the constant current source as well. The method for adjusting the negative temperature coefficients of the constant current source and the constant current source utilizing the same have the advantage of being capable of conveniently and greatly adjusting to obtain the negative temperature coefficients of the constant current source.

A method for improving the self-pollination ability of tobacco under abiotic adversity stress, specifically, when tobacco encounters abiotic adversity stress such as low temperature and drought during the budding and flowering stages, resulting in lower stamens than pistils and reduced self-pollination ability , Spray gibberellin solution with a concentration of 50-100 mg / L on flowering branches, with an average of 30 ml of gibberellin solution per plant, spray once every 5 days, and stop spraying when the stress disappears. The invention regulates the elongation of the pistil and the stamen, makes the stamen elongate faster than the pistil, achieves good self-pollination conditions that 4 stamens are higher than the stigma of the pistil, and 1 stamen is lower than the stigma of the pistil, and improves the self-pollination of tobacco ability and self-seed setting rate, preserve flowers and promote fruit, and improve seed yield.

The invention relates to a method used for digital bus information releasing and group control and a device thereof. The technical measure comprises the following steps: a vehicle terminal system, an electronic station board system and a vehicle technical information management centre are arranged, the electronic station board system is the vehicle technical information management centre are connected into a bi-directional communication network by line link, the vehicle terminal system transmits the vehicle information to the electronic station board system in a wireless communication, the electronic station board system reports the information to the vehicle technical information management centre, the bus coming to station at each station can be found out by inquiring a database, the station arriving time of the bus is calculated according to experimental data including average running speed, average running time between the stations and the like, finally, the arriving time is fed back to the electronic station board system, and the arriving time is displayed to the waiting passengers in a digital way. The method can effectively solve the problems of bus reduction in city and dispatching, information releasing, passenger facilitation, intelligent management control and the like. Therefore, the method realizes intelligent bus dispatching.

A method for improving self-pollination capacity of tobacco under abiotic stress concretely includes the steps that during a squaring stage and a flowering stage of the tobacco, when the tobacco encounters with abiotic stress such as low temperature and a drought, stamens are lower than pistils, and the self-pollination capacity is lowered, a gibberellins solution with the concentration of 50-100 mg / L is sprayed to flowering branches, 30 ml of the gibberellins solution is sprayed on each plant averagely and sprayed once every five days, and spraying is stopped when stress disappears. Extension of the stamens and the pistils is adjusted and controlled, the stamens are made to extend faster than the pistils, the good self-pollination condition that the four stamens are higher than pistil stigmas, and one stamen is lower than the pistil stigmas is achieved, the self-pollination capacity and the selfing setting percentage of the tobacco are improved, flowering and fruiting are promoted, and the seed yield is increased.
