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。

H-acid has two sulphonic groups, which can be dissociated in aquatic solutions. At pH 2.5, only one of them dissociated.

H-酸萘环上含有的两个磺酸基团，在水溶液中可以解离一个或者两个。pH2.5条件下，主要有一个磺酸基团解离，此时，H-酸通过一个磺酸基团吸附在TiO2表面，占位小，饱和吸附量大，但吸附键较弱，吸附较可逆。pH5.0条件下，主要有两个磺酸基团解离，此时，H-酸通过两个磺酸基团吸附在TiO2表面，占位大。

Water uptake by seeds rapidly increased with imbibition, and did not exhibited a typical triphasic pattern of water uptake. Rate of electrolyte leakage and relative leakage from seeds dramatically increased up to 3 h of imbibition, and then declined. The time and thermal time required for 50%germination seeds were 5.5 h and 7 degree days, respectively.

在吸胀过程中，种子含水量迅速增加，不表现出典型的吸水三阶段模式；种子的电解质渗漏速率和相对电导率显著增加直到3 h，然后下降。50％种子萌发需要的时间和热时间分别是5.5 h和7℃d。

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.

上述两种结合了H.264/AVC熵编码器特征的内容选择性加密算法，由于其加密后的视频码流的句法结构完全符合H.264/AVC视频编码标准，与传统的基于块数据的块加密算法相比较，本文提出的两种内容加密算法可以使得加密后码流在无需解密的情况下，实现H.264/AVC视频编码标准为移动视频应用而设计的诸多特性，如：增强传输鲁棒性的数据分割技术和非均衡保护技术，以及直接做匹配信道带宽的分级编码操作等，具有更高的灵活性和计算效率，从而可以灵活运用于各种应用场合。
