An engine control apparatus includes an engine target speed set unit 51 setting a first target speed through a throttle dial, a relief engine maximum speed calculation unit 52 calculating a second target speed limiting a maximum target speed in a relief operation according to a load pressure of a hydraulic pump, a speed control means controlling an engine speed such that the engine speed is equal to lower one of the first target speed and the second target speed, a determination means determining whether an engine torque assist action of a generator motor is performed, based on a deviation between an target speed and a real speed of the engine. When the determination means determines that the engine torque assist action is performed, the speed control means controls the engine speed to be equal to the target speed through the engine torque assist action of the generator motor.

The invention relates to an improved ultrasonic-assisted pollen mediated plant genetic transformation method, and aims to obviously increase the setting percentage of the plant fertilized by pollen subjected to ultrasonic treatment, thereby increasing the number of transformants obtained for each treatment. The method comprises the following steps: by using an agrobacterium Ti plasmid carrying an exogenous gene segment, colibacillus plasmid or any other DNA vector as a genetic donor and using plant pollen as a receptor, mixing the pollen and exogenous DNA in a 5-50% sucrose solution subjected to aeration and low-temperature treatment, and transferring the exogenous gene into the receptor pollen under the assisting action of ultrasonic; fertilizing the treated pollen onto the stigma of the plant, and harvesting when the grains become ripe; and in the subsequent growth season, sowing the harvested seeds which are obtained after the fertilization of the transformed pollen, screening the germinated seeds and seedlings, carrying out PCR (Polymerase Chain Reaction) amplification and Southern hybridization on the DNA of a seedling sample, and further determining the transformant. The method provided by the invention does not need tissue culture, does not have species or genotype dependency, and can shorten the genetic transformation breeding time and save the manpower and material resources.

A control system for a vehicle includes an input including a rotatable rotary element and a controller. The controller executes a trailer backup assist mode including interpreting a first instantaneous position of the rotary element as a trailer control commanding position and generating a vehicle steering command based thereon. The controller also executes a parking assist mode including implementing a parking assist action corresponding to a second instantaneous position of the rotary element.

The invention provides a method for depolymerizing lignite by using an ionic liquid, belonging to the technical field of comprehensive utilization of lignite. The method comprises the following steps: selecting an ionic liquid which is beneficial to efficiently depolymerizing lignite, adding lignite powder and the ionic liquid into a reaction kettle, heating under the assisting action of microwaves to 50-350 DEG C, and reacting for 2 minutes to 5 hours to obtain a reaction product; after the reaction finishes, separating the reaction product from residues by a high-speed centrifugal separation method or an organic solvent washing and filter membrane filtration method; and washing the supernatant or filtrate with water, evaporating to obtain the organic solvent, reaction product and ionic liquid, wherein the organic solvent and ionic liquid can be recycled, and the lignite reaction product can be separated by the organic solvent to obtain high-added-value organic chemicals of alkyl aromatics and multielement cyclic aromatics containing alkoxy groups and phenolic groups. The method has the advantages of simple technique, clean process, and high added value of the product, and needs no or little harmful or volatile organic solvents.

The invention discloses a method for assisting communication dispatching fault diagnosis. The method comprises the following steps of (1) obtaining an alarm optical link according to alarm circuit information; (2) if the alarm optical link just passes through one optical fiber cable section, directly listing an alarm optical fiber cable section by the system; if the alarm optical link passes through multiple optical fiber cable sections and other alarm optical links exist at the same time, screening the optical fiber cable sections by comparing the optical fiber cable sections which are passed by each alarm optical link by the system, limiting the number of fault optical fiber cable sections to one or several, and thus providing an assisting action which is accurate or is furthest and approximately accurate for next step fault processing. According to the method and the system, disclosed by the invention, system software is utilized for assisting communication dispatching to diagnose a fault point at a faster speed, thus the pre-processing time of communication repairing is shortened, the workload of a communication dispatcher is greatly reduced, and the reliability of power communication is enhanced; meanwhile, the range affecting the business can be quickly and accurately found out by utilizing the system when a communication circuit needs to be overhauled, and thus the influence of communication overhauling on the running of a communication network is reduced to the minimum.
