    Abstract
    The emergence of micro-priming systems expedites the demand for balancing the inherent contradiction between energy and safety in primary explosives. This paper proposes a new strategy (metal organic framework/reactive antistatic agent strategy, MOF/RAA strategy) which introduces the reactive antistatic agent (WO3) into ternary copper azide /carbon activity system by carbonization and azide of polyoxometalate-based metal-organic frameworks. Subsequent characterization validates that the novel reactive multi-component system (ternary copper azide /carbon/tungsten trioxide) performs well with both high electrostatic safety and remarkable detonating ability (detonate CL-20 as low as 0.98 mg) due to the electrical conductivity and active participation in secondary reaction of reactive antistatic agent (WO3). In general, this discovery has obtained prominent achievements in the application of copper azide in micro-initiating systems, providing a safe yet energy simul-taneously enhanced way for the design and synthesis of novel energetic compounds.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
