A portable photosynthesis system made by PPSYSTEM Ltd. was used to study the photosynthetic properties of 3 cultivarsof Rubus idaeus under the field conditions. The results indicated that the individual leave net photosynthetic rates had 2 peaks during a day,an obvious photosynthetic midday slump was observed in A,there was a significant difference in midday depression among the 3 cultivars;evaporation rates of B and C had 2 peaks during a day,while A had 1 peak,and an obvious midday slump was observed in B and C;Stomatic conductance is the key factor of midday slump;Compared with B and C,A had a higher water using efficiency,which will consume less soil water.

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.
