The present invention provides a process for preparing a cellulose solution. NMMO with a relatively low concentration and non-activated pulp are continuously mixed online, the mixed premix is dewatered in evaporation dewatering equipment until an NMMO concentration suitable for swelling is achieved, then, sufficient swelling is carried out under this condition, and the uniformly-mixed and sufficiently swelled pre-swelling solution is subjected to depressurized evaporation dewatering and dissolving by thin-film-evaporation equipment thereby obtaining a high-concentration, uniformly-dissolved and excellently-uniformity cellulose solution. The present invention further provides continuous preparation equipment for the process for preparing a cellulose solution. According to the present invention, the conflict between uniform mixing and sufficient swelling during the preparation of a high-concentration cellulose solution is solved, and problems in storage and transportation safety caused by using high concentration NMMO in the conventional technologies are prevented.

Process for preparing cellulose solution and equipment therefor

An ITC-IGBT and a manufacturing method therefor. The method comprises: providing a heavily doped substrate, forming a GeSi/Si multi-quantum well strained super lattice layer on the surface of the heavily doped substrate, and forming a lightly doped layer on the surface of the GeSi/Si multi-quantum well strained super lattice layer. The GeSi/Si multi-quantum well strained super lattice layer is formed on the surface of the heavily doped substrate through one step, simplifying the production process of the ITC-IGBT.

Embodiments of the present invention disclose a service data scheduling method and related devices. The method includes: receiving a service attribute message; obtaining a user priority of a UE according to the service attribute message and attribute information of each service corresponding to service data of the UE that is cached locally; granting authorization to the UE according to user priority of the UE; granting authorization to each service of the UE according to the authorization granted to the UE and the service priority of the service of the UE; and sending authorization information of the each service corresponding to the service data of the UE that is cached in the base station controller to the base station controller. When the service data of the same user is cached in the base station and the base station controller in a distributed way, service data scheduling for a user is implemented.
