Abstract: A detection method for determining chloride ions content in sea sand includes the steps of drying sea sand to a constant weight, adding the dried sea sand to boiling deionized water, fully stirring, and standing and filtering the deionized water to obtain washed sea sand and a washed filtrate. The washed sea sand is then ground into a powder and added into deionized water and fully stirred, the deionized water then filtered to obtain a powder filtrate. Half of the washed filtrate and half of the powder filtrate is then mixed and stirred to prepare a mixed filtrate. The chloride ions content in each of the washed filtrate, the powder filtrate, and the mixed filtrate is then measured by using a silver nitrate titration method. The detection results are then analyzed and corrected to obtain the chloride ions content in the sea sand.

Abstract: The present disclosure relates to a communication apparatus and a data transmission method. In an example, the communication apparatus includes a universal serial bus (USB) protocol layer, a USB adapter layer, a transport layer, and a physical layer. The USB protocol layer is configured to send first data to the USB adapter layer. The USB adapter layer is configured to perform physical link adaptation on the first data to obtain second data and send the second data to the transport layer. The first data is adapted to a first physical link, the second data is adapted to a second physical link, and a bandwidth of the first physical link is lower than a bandwidth of the second physical link. The transport layer and the physical layer are configured to process the second data and send processed second data to a receive end through the second physical link.
