Abstract: Disclosed is a method for producing battery-grade nickel sulfate by using laterite nickel ore comprising the following steps: sorting the laterite nickel ore to obtain lump ore and sediment ore; crushing the lump ore, and then performing heap leaching, to obtain a crude nickel sulfate solution A; separating the sediment ore to obtain high chromium ore, low iron, high magnesium ore, and high iron, low magnesium ore, and drying, roasting, reducing, and sulfurating the low iron, high magnesium ore to obtain low nickel matte; blowing and performing water extraction on the low nickel matte, and then performing oxygen pressure leaching, to obtain a crude nickel sulfate solution B; performing pressure leaching on the high iron, low magnesium ore to obtain a crude nickel sulfate solution C; and performing extraction on the crude nickel sulfate solutions A, B, and C, and then evaporating and crystallizing, to obtain battery-grade nickel sulfate.

Abstract: The present invention relates to an apparatus for measuring the balance ability; postural deviation, reflex and fall risk assessment of a human subject. In particular, the present invention comprises of an elastic support mounted platform with dynamic response to external motion stimuli, a IMU and data analysis software processing device. The dynamic response from the platform also simulates realistic experience in moving over rough terrain with different topography.

Abstract: An establishing method of a knowledge library engine based on emergency management includes steps of extracting relevant data from unstructured text information, filtering out unwanted data and improving a structure of the relevant data, so as to ensure homogeneity of the relevant data; structurally analyzing a text content of obtained information, extracting a feature thereof and storing the feature in the feature library as a key word of a knowledge; and processing the obtained information with the automatic word segmentation module, then classifying a result according to an information classification standard, and establishing an association of the knowledge and information classification. A querying method of the knowledge library engine based on emergency management includes steps of: understanding semanteme, understanding knowledge, and querying knowledge.
