Abstract: A composite solution for enhancing induced disease resistance of lentinan (LNT) to a plant, a preparation method of the composite solution, and a method for enhancing induced disease resistance of LNT to a plant are provided. The composite solution for enhancing induced disease resistance of LNT to a plant includes: an LNT-containing solution and an SPc-containing solution, where SPc is a dendritic macromolecule functionalized by an amino functional group, and has a structural formula shown in formula I, where n=1 to 100. An LNT/SPc complex is produced in the composite solution. SPc spontaneously combines with LNT through hydrogen bonding, such that an agglomerate structure formed by LNT in an aqueous solution is broken and reduced to a nano-scale particle size, and a spherical particle is produced, which can significantly reduce a contact angle of the LNT aqueous solution, and promote the distribution and diffusion of LNT.

Abstract: A method for detecting abnormal direct current voltage measurement in a modular multilevel converter high voltage direct current transmission system is provided. In the method, a valve group voltage at a detection pole is obtained, voltages at voltage measurement points at the detection pole are collected, and comparison and determination are performed based on the actual arrangement of the voltage measurement points, and then whether an abnormal measurement occurs at each of the voltage measurement points is determined.

Abstract: Provided is a carbon-based functional material (simply as FCN or FCN material) and applications thereof. The carbon-based functional material consists of three elements, namely carbon, nitrogen, and oxygen, having sp2 carbons as the backbone and functional groups R formed on the surface and/or periphery of a carbon backbone substrate, the R functional groups being a combination of groups such as a hydroxyl, carboxyl, ether bond, epoxy, carbonyl, aldehyde, ester, and alkyl.

Abstract: The present invention provides a method, which is used with trace amount, can initiate an active endogenous response of plants, and can obtain expected effects such as growth acceleration and yield increase of the plants. The present invention further provides preparation of a signal carrier material for implementing the method. In the method, by utilizing genetic information stored in the plants, the plants can adapt to an environment through a signal which makes the plants mistakenly perceive, thereby achieving an expected objective. The method is suitable for planting of crops in regions with poor natural conditions or severe climate changes.

Abstract: A novel carbon-based material (abbreviated N-FCN) composed of carbon, hydrogen, oxygen and nitrogen and application thereof. The raw materials of the novel carbon-based material are derived from natural or simple inorganic matter which provide the four elements of carbon, hydrogen, oxygen and nitrogen. A composite organic matter is formed at low voltage and low energy and comprises a carbon base in graphite structure, at least one or more composite organic functional groups and an organic small molecule, wherein at least two or more amino acids may be detected in the organic small molecule. The novel carbon-based material may induce an active response of an omanism. After a trace amount of the novel carbon-based material is released into a biological growth environment, the organism will actively respond to the novel carbon-based material.

Abstract: A tap assembly for a measurement device has a clamp base, a main assembly, a piercing member, a clamp member defining an anchor surface, and a bolt member defining a shaft portion and a head portion. The clamp base has a brace portion defining a bolt opening. The piercing member is supported by a contact plate of the main assembly. The clamp base is attached to the main assembly to define a clamp notch. The contact plate is adjacent to the clamp notch. The shaft portion of the bolt member extends through the bolt opening and engages the anchor surface. At least a portion of the conductor is arranged within the clamp notch between the clamp member and the piercing member such that axial rotation of the bolt member displaces the clamp member towards the piercing member to cause the piercing member to engage the conductor.

Abstract: A method for treatment of saline-alkali land is provided, comprising at least one self-circulating process, the self-circulating process comprising: step 1, converting saline-alkali water deposited in the saline-alkali land into acidic water by an electrolysis system, whereby the salt content of the acidic water is lower than that of the saline-alkali water; and step 2, leaching the saline-alkali land with leaching water comprising the acidic water. A device for treatment of saline-alkali land according to the above-described method is also provided, comprising: an electrolysis system for converting saline-alkali water deposited in the saline-alkali land into acidic water, whereby the salt content of the acidic water is lower than that of the saline-alkali water; and a leaching system for leaching the saline-alkali land with leaching water comprising the acidic water.
