Abstract: A nucleotide sequence is shown in SEQ ID NO.1. The gene encodes mannosyltransferase I. The gene plays an important role in the normal reproductive development of the Nilaparvata lugens (Stål). Inhibition of the function of the gene may reduce the survival rate of the Nilaparvata lugens (Stål) and hinder embryonic development. With respect to reduction of the survival rate of the Nilaparvata lugens (Stål) and hindering of embryonic development, the present invention can reduce the harm of the Nilaparvata lugens (Stål) to rice by killing the Nilaparvata lugens (Stål). By using the characteristic that the nucleotide sequence of a highly conserved target gene has no homology with the nucleotide sequence of natural enemies of the Nilaparvata lugens (Stål), RNA interference is performed at a nucleic acid level, to avoid the harm to non-target organisms such as natural enemies, thereby realizing green control of the Nilaparvata lugens (Stål) while controlling pests.

Abstract: This application relates to a tab flattening device. The tab flattening device includes: a roller configured to convey an electrode plate, a cover, and a flattening portion. The surface of the roller is in contact with the electrode plate in a contact region. The cover surrounds the contact region peripherally and includes a feed-in guide surface oriented toward the contact region. The flattening portion is disposed protrusively on the feed-in guide surface, and located opposite to a tab of the electrode plate. A tab guide surface is formed on the flattening portion. Along a feed-in direction of the electrode plate, the flattening portion is at least partially located upstream of the contact region.

Abstract: A link balance adjustment method includes the following steps. A connection port initiates a balance adjustment process through an interrupt signal. A microprocessor provides an adjustment parameter for an external device from a register and transmits the adjustment parameter to the connection port. A measurement signal is initiated by the microprocessor, and the measurement signal enables the connection port to measure the signal quality after the adjustment parameter has been applied by the external device. The microprocessor determines whether the connection port needs to perform a preprocessing. When the microprocessor determines that the connection port needs to perform a preprocessing, the connection port performs the preprocessing and generates preprocessing data. The connection port transmits the preprocessing data to the register. The microprocessor reads the preprocessing data or the signal quality in the register.
