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。

In different conditions on fluidized state and stability of conical fluidized bed. The conlusions are: the conical angel of the conical fluidized bed is 20°, the fluidized state havesmall difference in conical distributor and distributor plate. The angle of conical bed increase,the fluidized state will have big difference. The angle is 60°and the conical as distributor, themass of fluidized is less, the most of material is the bottom of conical bed. The effect ofdistributor plate is much better than the conical distributor. Sawdust and rice hull can fluidize.The annular gap of conical distributor different, the angle of conical bed is same, the fluidizedquality of 10mm annular gap is better than the other conical distributors. The annular gap ismore wide, the conical bed have more slugging phenomenon and the pressure fluctuate is turnbig.In the experiment the flow of 2％and 4％distributor plates don\'t easy to control, becausethe pressure is very big and the pressure fluctuate of conical bed is too big.

在不同的条件下对锥形床的流化状态和稳定性进行了研究，结果得出：锥形床的锥角为20度时，分布锥和分布板的流化状态相差不明显，随着锥形床锥角的增大，分布锥和分布板的流化现象会出现明显的变化，锥形床锥角越大，分布锥的流化状态变化越明显，流化的的物料越少，大量物料都聚集在锥形床底部，而分布板在加料量少的情况下，能流化起来。10mm、15mm和20mm环隙分布锥在锥形床锥角相同条件下，10mm环隙分布锥的流化质量要好于其它两个分布锥，环隙越大越容易出现腾涌现象的产生，压降波动范围增大。2％、4％和6％开孔率分布板在本实验测定时，2％和4％开孔率分布板的流量不容易调节，同时产生的压降波动范围也很大，比较来说，6％开孔率分布板流化质量好些。

The study shows that generally the mathematics view of normal university students majoring in mathematics is right, they depict mathematics learning as a dynamical process. Besides some special traits belong to mathematics, estimation, measurement and decision making themselves are also in the math field; however there are still some people warp the mathematics view, believe that mathematics is an apodeictic collection. Haven't realized the power that mathematics can improve people's taste ability and perfect people's personality, they believe that math learning is a passive process during which students receive acknowledge. What is more, there are different believes existing in the understanding of mathematics essence, mathematics value and mathematics learning. These believes vary with different university students from different grades and genders.

研究数据表明，高等师范院校数学系大学生的数学观总体上来说还是比较正确的，认为数学学习是一个动态的过程，认为数学在社会生活当中有一定的作用，并且认为做数学除了有特定的内容以外，估算、测量及决定本身也为做数学；但仍有一小部分人的数学观还存在着偏差，认为数学是一堆绝对真理的总集，对数学能够培养人的审美能力以及数学能完善人的个性等较高层次的价值没有意识到，认为数学问题仅是与教材内容相关的习题和考试中的试题，并且对数学学习不感兴趣，认为数学学习是学生被动接受知识的过程，并且不同年级以及不同性别的大学生在对数学本质、数学价值以及数学学习的认识上都存在着差异。

Credit belongs to the man who really was in the arena, his face marred by dust and sweat and blood; who stives valiantly; who errs and comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms the great devotions; who spends himself in a worthy cause; who at best knows in the end the triumph of high achievement, and who at the worst, if h

学习英语最常遇到的问题，便是词汇不足。词汇不足的人在英文听、说、读、写各方面的能力都会受到严重限制。所以词汇量的多少在英语学习中占有重要地位。一般认为背单词是件既吃力，又往往成效不彰的苦差事。实际上，若能采用适当的方法，是可以缩短扩大词汇量所需的时间，并且提高记忆单词的质量的。下面将介绍五种单词记忆法。一、结合记忆法。将比较生疏，不常用的单词放入一定的语言环境--句子中，结合句意来记忆单词。遇到此单词时，若词义忘记，则可通过回忆所
