Usually, most Chinese scientific papers basically require English titles, English abstracts and keywords.
Scientific papers depend on where you publish them. The English version must be in English. Some Chinese versions require the title of the chart to be in English, and some references are in English, such as Journal of China Nonferrous Metals Society.
Others, such as foreigners' names, require English, or require both forms and table titles to be in English. Different publications have different requirements.
