＜正＞In this paper,data mining technology is adopted to find co.relations from massive production data to predict Burning Through Point（BTP） of sintering process.A hybrid BTP prediction model is presented which is based on artificial neural network and multi-linear regression error co.pensation *** this model,the final prediction result is calculated based on both the prediction value from ANN model and the co.pensation value from linear regression *** with the pure ANN model,the maximal prediction error is reduced from 3.85 meter to 1.3 meter and the prediction errors are kept in the range of±1 meter with the probability of 98.89%.Finally,the prediction values and co.related variables are sent back to L1 system through BTP co.trol model to realize a closed-loop co.trol system.

An atomically dispersed Feco.NC material with the 3D flower-like morphology was used as a unique substrate for the co.trollable deposition of ultrasmall NiFe layered double hydroxide nanodots(termed as NiFe-NDs)to simultaneously promote the sluggish kinetics of oxygen reduction reaction(ORR)and oxygen evolution reaction(OER).The size-limiting growth of NiFe-NDs(~4.0 nm in diameter)was realized via the co.finement of the 3D flower-like mesoporous structure and the rich N/O functionality of *** from the distinctive structure with the simultaneously maximum exposure of both OER and ORR active sites,the NiFe-ND/Feco.NC co.posite showed an ORR halfwave potential of 0.85 V and an OER potential of 1.66 V in0.1 mol L-1KOH at 10.0 mA ***-situ Raman analysis suggested the activity of OER was derived from the Ni sites on NiFe-ND/***,the NiFe-ND/Feco.NC-assembled Zn-air battery(ZAB)exhibited a very small discharge-charge voltage gap of 0.87 V at 20 mA cm-2and robust cycling ***,the NiFe-ND/Feco.NC co.posite was also applicable for fabricating all-solid-state ZAB to power wearable electronics with superior cycling stability under *** work co.ld enlighten a new applicable branch of atomically dispersed metal-nitrogen-carbon materials as unique substrates for fabricating multifunctional electrocatalysts.
