    Abstract
    以玉米淀粉(St)和两性离子单体(ZM)为主要原料,通过溶液聚合和化学交联制备了两性离子接枝共聚淀粉(ZS).使用FTIR、TGA-DSC、XRD、SEM-EDS对产物进行了表征,评价了产物对Cu2+的静态吸附效果.结果表明:St从结晶态转变为无定型态,产物在270℃以下热稳定性良好,对Cu2+的最大吸附量为63 mg/g,吸附过程符合准二级动力学模型和Freundlich等温模型.产物在高浓度Cu2+溶液中不聚沉,吸附性能良好.

    • 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
