    Abstract
    The DC reactor is an important piece of equipment for restraining loop and ripple currents in the international thermonuclear experimental reactor(ITER)converter power supply system.As the reactor is operated at a steady state of 27.5 kA and needs to withstand a peak current of 175 kA,so the design of the DC reactor used in the ITER converter power supply system is necessary.A new water-cooling dry-type air-core reactor is designed in this work.The detailed structural parameters are calculated by theoretical formulas,and then the structure is optimized by electromagnetic simulation with ANSYS.Finally,thermal and dynamic stability analyses are performed to verify the temperature and stress at a rated current of 27.5 kA and pulsed current of 175 kA.The analysis results show that the temperature and stress meet the requirements of the ITER converter power supply system.

    • 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
