Abstract: A sodium-ion pouch cell belongs to the technical field of new energy materials and devices. The pouch cell and comprises a cathode piece, a diaphragm, a presodiated anode piece, an electrolyte, a tab and an aluminum plastic film package, and is obtained by sequentially laminating 1 to 30 cathode pieces and 2 to 31 presodiated anode pieces in a Z-shaped manner, adding the electrolyte and packaging, the sodium-ion pouch cell is characterized in that: the cathode piece contains an O3 layered oxide cathode material, a chemical formula is NaaNibZncFedMneTi(1-b-c-d-e)O2, 0.8?a?1, 0.2<b?0.5, 0<c?0.1, 0<d?0.2, 0.2<e?0.5, the presodiated anode piece contains a hard carbon anode material, and a double-sided density of the cathode piece is 28 mg/cm2 to 33 mg/cm2; and a double-sided density of the anode piece is 14 mg/cm2 to 16 mg/cm2, and a battery capacity is 0.1 Ah to 10 Ah.

Abstract: A method and system are provided. The method includes positioning facial feature base points in a face image in an obtained image. A deformation template is obtained, the deformation template carrying configuration reference points and configuration base points. In the facial feature base points, a current reference point is determined corresponding to the configuration reference point, and a to-be-matched base point is determined corresponding to the configuration base point. A target base point is determined that corresponds to the configuration base point and that is in a to-be-processed image. The target base point and the corresponding to-be-matched base point forming form a mapping point pair. A to-be-processed image point is mapped to a corresponding target location according to a location relationship between the target base point and the to-be-matched base point, and a location relationship between the mapping point pair and the to-be-processed image point.

Abstract: A social communication system and a method thereof are provided. The system includes a server apparatus and a user device. The user device transmits an authorization request to the server apparatus, and the server apparatus inquires an authorized individual whether to agree a user to access a friendship list of the authorized individual. When the authorized individual agrees the user to access the friendship list of the authorized individual, the friendship list of the authorized individual is added to a FOF database. The user device transmits an anonymous social communication service request to the server apparatus to obtain an anonymous social communication service for the user and the authorized individual. Besides, when the service is stopped, the server apparatus inquires both of the authorized individual and the user whether they agree to provide their profiles to each other as the basis for the friendship.

Abstract: A method for real-time conversations and comment with each other in a mobile device comprises the following steps. In the step (a), it activates a communication module of real-time conversations and comment with each other of a first mobile device. In the step (b), it performs a matching process for a user of the first mobile by a server. In the step (c), it provides a topic of chat for the user of the first mobile device for conversations by using the communication module of real-time conversations and comment with each other or by using the server. In the step (d), the user of the first mobile device transmits a first message to the successfully matched user of a second mobile device and makes comments for a second message from the user of the second mobile device.

Abstract: A method, a server and an apparatus for lecture feedback are provided. In the method, an adding request is received to establish a lecture. A login for the lecture from each of at least one audience apparatus is received to provide a presentation data to each of the at least one audience apparatus. The presentation data includes several pages. A usage behavior of each audience apparatus executing on each of the pages of the presentation data is monitored, and the usage behaviors of all of the at least one audience apparatus are analyzed to provide a feedback of the lecture.
