Abstract

The heat release rate generated when a fire occurs in a railway vehicle is one of the most important factors when designing precautions for railway facilities such as railway tunnels. In this study, the fire characteristics of interior materials required to analyze the propagation of a fire in a new railway vehicle were identified via an experimental method. The fire characteristics of the main interior materials across various radiant heat fluxes were analyzed, and the ignition temperature of the interior materials was predicted using the heat release rate and ignition time. By predicting the ignition temperature, the critical heat flux and ignition temperature were confirmed to be low for the flooring of the main interior materials. The derived fire characteristics (ignition temperature and heat release rate) for each material can be used to analyze the fire propagation phenomenon in railway cars.

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
