求翻译：As the tubes were tested in the laboratory without air circulation the heat transfer from the glass cover to ambient as well as inside the glass is mainly due to natural convection or conduction in the lower part. So far, there is no theory available for free convection of gas from a hot flat plate placed in a cylinder是什么意思？ 待解决
