Abstract: The invention belongs to the field of mineral flotation collector materials, and particularly discloses a method for preparing thionocarbamate. In the preparation process, xanthate and 2-haloethanol are esterified to obtain O-alkyl-S-hydroxyethyl xanthate, and then O-alkyl-S-hydroxyethyl xanthate and fatty amine are reacted to obtain a mixture of thionocarbamate and 2-mercaptoethanol. The mixture of thionocarbamate and 2-mercaptoethanol is washed with alkali, and the oil phase and water phase are separated. The oil phase and water phase are thionocarbamate and 2-hydroxyethylthiolate, respectively, and 2-mercaptoethanol is obtained by washing with an acid. 2-alkylthioethanol is obtained by reacting 2-hydroxyethanethiolate with alkyl halide, and then with carbon disulfide and alkali to prepare O-alkylthioethyl xanthate. Thionocarbamate, 2-mercaptoethanol and O-alkylthioethyl xanthate prepared by this method possess high yield and high purity.

The array substrate comprises a plurality of signal lines and a repairing line intersecting with and isolated from the signal lines. The detecting method comprises applying a first detection signal to the plurality of signal lines; and applying a second detection signal different from the first detection signal to the repairing line, in the case that the first detection signal is applied to the plurality of signal lines.

Abstract: A method of brewing tea, includes the following steps: (1) obtaining tea leaves and placing the tea leaves in water at 0 to 70° C. to carry out washing, and draining; (2) adding the tea leaves in hot water at 70 to 100° C. in one or more times and brewing for 0.1 to 40 minutes; and (3) obtaining and adding an appropriate amount of water at 0 to 70° C. or an ice cube to tea after the brewing in step (2), so as to lower a temperature of the tea to a drinkable temperature. This method adopts a way of high-temperature brewing and rapid cooling, and may satisfy different people's preference in tea.

Abstract: A method is provided for adjusting a photographing focal length of a mobile terminal, including: when a mobile terminal enters a camera mode and displays a shooting preview screen on a display, receiving a focal length adjustment start instruction when a touchpad is touched; executing the focal length adjustment start instruction to display a focal length indication bar on the display, so as to prompt the focal length adjustment; obtaining gesture information generated by an operation on the touchpad after the focal length indication bar is displayed; then determining a focal length adjustment instruction using the gesture information; and adjusting a focal length using the focal length adjustment instruction, and displaying, on the shooting preview screen, an image after the focal length is adjusted.

Abstract: A disposable container for collection of microbe containing fluid samples is useful in a variety of microbial detection methods. One end of the container is provided with a lid comprising fluid flow apertures on one surface and a membrane filter (MF) on an opposed surface.
