The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.
用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测,重点分析了23m、39m两层高度的观测结果,同时把观测期分为春季和冬季两个不同时间段作了对比:结果表明,不管冬季还是春季,39m高度所测的总通量值和夜间通量值都要小于23m的观测值,这种通量差别表明:23m高度的观测结果更接近当地生态系统与大气之间的通量交换值,在此种生态类型条件下用涡度相关法测碳通量时,在23m、39m两层高度之间仍然存在大气平流现象;该试验区植被在冬季仍然可以进行光合作用,而且光合作用所吸收的CO2大于呼吸作用所排放的CO2,因此该种生态系统在冬季仍表现为碳汇;春季的碳通量值为冬季的2倍以上。

This paper puts forward a new Difference Group Query based on two query points, the methods in GNN query which define several query points in a MBR are not suitable for the specific Difference Group Query in our paper. In this paper, based on the algorithm in YFK-CNN, we use the definition of hyperbola, divide the query space into several sections to delete the unsuitable space, furthermore, we develop several asymptotes from the definition of hyperbola, simplify the hyperbola based filter strategy in the search space.
文章提出了一种基于2个查询点的差值聚合查询,基于单查询点的YPK-CNN,利用双曲线性质把查询空间分成几大部分,在此基础上计算出双曲线的渐近线以简化删减条件,直接删减掉不符合条件的搜索空间。

The progress levels of symptoms after pathogen infection showed that interaction of gray leaf spot pathogen and host has differentiation or polymorphism. The progress levels of symptoms is different.The aggressively has polymorphism. The pathogenicity of different isolates in same cultivar has polymorphism, or the host reaction type of same isolate in different cultivars has polymorphism.The host reaction type has differentiation. There are seven types of host reaction in cultivar and inbred after infected by GLS pathogen:Rectangular lesion without chlorotic halo, Rectangular lesion with chlorotic halo,Irregular lesion without chlorotic halo,Irregular lesion with chlorotic halo, Spot lesion with chlorotic halo,Rectangular and irregular lesionand Rectangular and spot lesion. The host reaction type is coalesced lesion when disease severely. Frequency of each reaction types is different.
通过对玉米灰斑病菌侵染后的显症过程的系统观察,可在组织水平上说明该病菌与寄主互作反应存在分化或多样性:玉米灰斑病菌不同菌株侵染后显症过程表现出明显的差异;玉米灰斑病菌在侵袭力上存在多样性,菌株间对同一种品种的致病性表现多样化,或者同一菌株对不同品种侵染引起的寄主反应表现为多样性;病斑反应型的分化,玉米灰斑病菌侵染玉米品种或自交系后,主要有7种病斑反应类型,即RH型、RN型、IRH型(不规则形具褪绿晕圈病斑)、IRN型(不规则形无褪绿晕圈病斑)、SH型、RI型(长矩形与不规则形混合病斑)和RS型(长矩形与斑点形混合病斑),若发病严重,病斑连成片,而且这些反应类型出现的频率也不同。
