说明：  MathType需要与其他文档编辑工具搭配使用，并且能够与office系列软件完美兼容，可用在编辑数学试卷、书籍、报刊、论文、幻灯演示等方面，是编辑数学资料的得力工具，所以受到了广大用户的一致好评。并且office系列本就内置有MathType的缩减版，这让用户们更加易于上手。(MathType needs to be used with other document editing tools, and can be perfectly compatible with office series software. It can be used in editing math papers, books, newspapers, papers, slide shows, etc. it is a powerful tool for editing math materials, so it has been unanimously praised by the majority of users. And the office series has a reduced version of MathType built in, which makes it easier for users to get started.)

One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle. It is often impractical to make a physical connection between the node and the vehicle which suggests an acoustic or optical wireless solution. For large amounts of data, the high bandwidth of underwater optical wireless is an advantage. A small, low-cost platform to demonstrate the potential of an optical wireless communications interface for underwater sensor nodes is demonstrated. To enhance the reliability and robustness of the optical wireless communication digital signal processing and error correction techniques are used. The system was tested in 3 and 7.7 meter tanks at 5 Mbps with the turbidity of the water controlled by the addition of Maalox.
