Abstract: La présente invention concerne un procédé, un appareil et un dispositif de détermination de bande passante de signal PCIe, et un support de stockage lisible par ordinateur. Un point de fréquence cible, auquel la densité spectrale d'énergie d'un signal PCIe d'une liaison de transmission à mesurer, après qu'un signal de sortie de ladite liaison de transmission a été soumis à une transformation de Fourier inverse, atteint une proportion prédéfinie (déterminée selon une exigence d'erreur de mesure de ladite liaison de transmission) de celle d'un signal d'origine, est obtenu par test, et le point de fréquence cible est pris comme bande passante du signal PCIe de ladite liaison de transmission. Par conséquent, une sélection précise de bande passante d'un signal à haut débit est réalisée. En outre, afin de mesurer le point de fréquence cible, une perte d'insertion d'un signal PCIe standard sur une liaison de transmission analogique est obtenue par test à l'avance, et après que la perte d'insertion de ladite liaison de transmission a été déterminée, une liaison de transmission analogique cible est sélectionnée pour simuler ladite liaison de transmission pour un test. Le test de sélection de bande passante de signal est réalisé dans la phase de conception de ladite liaison de transmission, et une sélection raisonnable de bande passante de signal PCIe est réalisée en conséquence.

Abstract: La présente demande concerne un procédé de communication, un dispositif de réseau et un dispositif terminal permettant de résoudre le problème selon lequel un surdébit de signalisation lié au rapport d'informations de position d'un dispositif terminal est élevé. Le procédé comprend l'étape suivante : un dispositif terminal envoie des premières informations de position à un dispositif de réseau, les premières informations de position étant déterminées en fonction d'informations de position mesurées et d'informations de position de référence, et la valeur des premières informations de position étant inférieure à la valeur des informations de position mesurées. Par comparaison avec des informations de position de mesure réellement mesurées d'un dispositif terminal, la valeur des premières informations de position est inférieure. Par conséquent, le nombre de bits des premières informations de position peut être inférieur au nombre de bits des informations de position mesurées. Une signalisation, qui transporte les premières informations de position, peut occuper moins de bits, ce qui réduit ainsi un surdébit de signalisation.

Abstract: An apparatus for testing the state of a glue path, and a test method therefor. The test method for testing the state of a glue path comprises the following steps: obtaining a three-dimensional (3D) space state image model of a 3D scanning glue path (S10); obtaining, according to the 3D space state image model of the glue path, state-related parameters of the glue path and a workpiece where the glue path is located (S20); and comparing the state-related parameters with domain values of an allowable parameter database, so as to obtain whether the glue path is qualified (S30). A 3D space state image model of a 3D scanning glue path is acquired first, so as to obtain an accurate and stable state of the glue path on a workpiece; and state-related parameters are obtained, and the obtained state-related parameters are then compared with domain values of an allowable parameter database, so as to obtain the deviation of the glue path. In this way, not only can the states of various types of glue paths be accurately and reliably detected, but testing can also be performed on a glue path of transparent glue, into which a fluorescent agent is forbidden to be added, or a glue path when applied glue and a glue carrier are in the same color and a workpiece is made of a transparent material.

Abstract: La présente invention concerne le domaine technique des batteries au lithium et divulgue un précurseur d'un matériau d'électrode positive en oxyde contenant du lithium, un matériau d'électrode positive en oxyde contenant du lithium, leurs procédés de préparation et leur utilisation, et une plaque d'électrode positive et son utilisation. L'indice de compression Δλ(P100) du matériau d'électrode positive satisfait : Δλ(P100)≥60 %+(y/x)×5 %, y/x étant le rapport molaire de Mn/Ni dans le matériau d'électrode positive. Le matériau d'électrode positive en oxyde contenant du lithium a une résistance et une stabilité de compression relativement élevées, ne se rompt que légèrement lorsqu'il supporte une pression relativement élevée pendant le processus de fabrication d'une plaque d'électrode, et peut être soumis en continu à des réactions de désintercalation/intercalation d'ions lithium sans rupture grave.
