Abstract: The N distribution and cycle in on Alpine Meadow Ecosystem by a compartment model was studied.The results showed that the N storage was 10 63t/hm 2,mainly existing as org. N in the soil pool.Although the total N was abundant,the available N was in deficiency.The N storage was 190 1±49 62kg/hm 2 in the plant sub system,and 79 26% of it stored in living roots.By estimating the N input and output amount in the Alpine Meadow Ecosystem,it appeared that the amount of N output(159 35kg/hm 2·a) was much m...

Abstract: 本文首次建立了用嵌套式聚合酶链式反应(nested-PCR)分别检测天津地区海水工厂化养殖大菱鲆和褐牙鲆腹水病病原菌迟缓爱德华氏菌(Edwardsiella tarda)和溶藻弧菌(Vibrio alginolyticus)的方法。以E781F和E781R为引物,扩增迟缓爱德华氏菌溶血素基因中781bp的片段,再以E485F和E485R为引物,扩增其中的485bp的片段;以V899F和V899R为引物,扩增溶藻弧菌胶原酶基因中899bp片段,再以V550F和V550R为引物,扩增其中的550bp片段。以其他常见海水鱼类致病菌为阴性对照,结果均无非特异性扩增。对迟缓爱德华氏菌和溶藻弧菌的检出灵敏度分别可达10fg和1fg细菌DNA,显著优于目前的检测方法。作者应用该技术对天津地区海水工厂化大菱鲆和褐牙鲆于2006年3月至10月连续进行监测,为有效地控制该病的流行提供了技术支撑。

A REVIEW ON INHIBITION MECHANISM IN LANGUAGE COMPREHENSION
语言理解中抑制机制的研究概况

Abstract: Inhibition plays an important role in language comprehension. In this article, first, the concept and the categories of inhibition were briefly introduced. And then three theories of inhibition were described: the Construction-Integration Model, the Structure Framework Building, and the Inhibition and Contents of Working Memory. Finally, three kinds of studies on inhibition were introduced. They are the inhibition for unrelated or inappropriate information from the interior of language, the inhibition for unrelated information from the exterior of language, and the inhibition on the procedure of cross-model language comprehension.
A neuro-fuzzy method for predicting the chaotic time series
一种预测混沌时间序列的模糊神经网络方法

Abstract: A neuro-fuzzy approach based on a novel hybrid learning method is presented, which can generate the best fuzzy rule set automatically from the desired input-output data pairs only and can give the initial neuro-fuzzy system and the initial parameters of fuzzy membership functions. Then the parameters of fuzzy membership functions and the weights can be easily tuned by employing neural network's self-learning techniques. This approach reduces the rule matching time and accelerates the speed of the fuzzy logic referencing and improves the adaptability of the neuro-fuzzy system. Using the proposed neuro-fuzzy system and the learning algorithms we simulated the prediction of the Lorenz chaotic time series, the results demonstrate the effectiveness of the chaotic time series prediction approach.

Abstract: The main purpose of this investigation was to examine the inhibition mechanism of skilled and less skilled Chinese language comprehenders. Based on Multi Media Language Comprehension Test (MMLCT), two groups of first year university students were selected as subjects. They were classified into two groups, more and less skilled Chinese comprehenders, according to their scores on MMLCT. Two experiments were conducted to examine the inhibition mechanism of the two groups of subjects in processing Chinese two character words. In the experiments, an experimental paradigm of combining self paced Moving Window and selective recognition task was used. A new method of externally inserting language distractors under self paced reading condition was also used. The inhibition mechanism was examined from two different dimensions of distractors in the two experiments. In the first experiment, the meaningful two character words and meaningless two character non words were used as distractors to examine the effect of the meaningfulness of distractors on inhibition mechanism. This was from a lower level of meaningfulness dimension. In the second experiment, the effect of semantic relevance of distractors to target items on the inhibition mechanism was examined. Semantic relevant and irrelevant two character words were used as the distractors. This was from a higher level of meaningfulness dimension. The results showed: (1) Inhibition mechanism was affected by the properties of distractors, such as meaningfulness and semantic relevance to target words. The more meaningful and semantic relevant the distractors are, the more difficult they will be inhibited. (2) The different skilled comprehenders were also different in the efficiency to inhibit external distractors. Less skilled comprehenders had less efficient inhibition mechanism. (3) The benefit effect of self paced paradigm on the inhibition mechanism of less skilled comprehenders decreased with distractive intensity. It could be concluded that at Chinese lexical processing level, subjects with different comprehension skills exhibited a difference in the effect of inhibiting external distractive information. Less skilled comprehenders showed a weaker inhibition mechanism.
Advances in the Studies of Breeding Primula
报春花属植物的育种研究进展

Abstract: The methods and achievements of primula breeding are reviewed. Primula is the largest genera in the Primulaceae, with about 500 species widely distributed in the world. The main methods employed in breeding primulas are intraspecific crossing and polyploid induction. Great achievements have been achieved in flower color, shape and primin-free primulas; several breeding programs in Europe, Japan and United States have contributed numerous primula cultivars and series. Contrary to this situation, China has no cultivars, although approximately 296 wild species are distributed in China. Further work should be undertaken to protect our primula resources, breed new cultivars and realize primula industrialization.
