The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。

BACE algorithm has the desired property that does not reduce the encoding efficiency of the CABAC entropy encoder compared to the CIME algorithm for CAVLC entropy encoder. Both CIME and BACE algorithms can adapt to the content security level by choose the amount and different key parts of the video stream to be encrypted, the theoretical and experimental results show that both these algorithms can effectively encrypt the video content. Due to the ability of encrypting the video content without violating the syntax, the BIME and BACE algorithms can be employed used for many advanced H.264/AVC coding options without first decrypting the video stream, like Data Partition and UnEqualized Protection for the enhancement of transmission robustness, and the scalable coding in order to match the different channel capacity.
