Abstract: A method for preparing unbleached biomechanical pulp from straw. Straw is used as a raw material, which is firstly pre-treated with hot water and hot steam, added with a small amount of alkali, and then softened by saturation with hot water, enzymatically treated by adding alkaline biological enzymes, refined, and washed. This method has the advantage that the whole production process does not need alkali recovery, thereby avoiding environmental pollution from the source. This technology conforms to the national industrial policy of resource conservation, economic recycling, energy saving and emission reduction. The present invention overcomes the problems of difficulty in recovering the alkali wastewater accompanying straw pulp and serious pollution in the prior art. This is of great significance for the industrial production of straw pulp and the development of the paper industry.

Abstract: Disclosed is a state estimation method for a power battery formation process based on convex space filtering, belonging to the technical field of power battery manufacturing. The method performs state estimation on a time delay system by a filtering method, and an iterative replacement method is provided for converting the state quantity at a time k to the state quantity at a time k?h and subsequent items, so as to combine time delay items, thereby avoiding the problem that the dimension is increased when a state matrix A and a state matrix Ah of a time-delay state quantity are subsequently combined into a new state matrix, and reducing the computation complexity and computation time in subsequent computations. Moreover, the estimation accuracy is also improved to a certain extent because of the cancellation of the same items in the iterative replacement.
