New Zealand white rabbits (3-4 months old, 3-4 kg weight) were the test animals, and they were divided into three groups proceeding in this study. In group A:One PLLA screw and one commercial screw were implanted in the right tibia. Two PLLA screws were implanted in the left. Furthermore, one PLLA bar was implanted in both right and left tibia respectively with onlay model in group B. Also,one PLLA plate was implanted in the left tibia and one commercial plate in the right respectively with onlay model in group C . Many tests were done on each sample in 1, 4, 8 and 12 weeks which included the observation of tissue response in group A, and the change of three-points bending, weight loss, molecular weight, crystallinity and morphology of fracture surface by scanning electronic microscopyin group B, and the change of three-points bending, weight loss and molecular weight in group C.

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.

利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统，对3个树莓品种的光合特性进行了比较研究，结果表明树莓叶片光合速率日变化呈双峰曲线，A品种&日中低落&现象明显，B、C品种不甚明显；B、C品种的蒸腾速率日变化曲线基本上为双峰型，日变化过程中的&午休&现象非常明显，而A品种为单峰型，日变化过程中的&午休&现象不甚明显；此外，叶片气孔导度与叶片光合速率的日变化趋势基本一致，呈平行变化趋势，说明气孔导度是影响光合速率的直接因子；较B、C品种而言，A品种具有较高的水分利用效率，说明其更能节约并有效地利用土壤水分。
