摘要：
Although widely applied in many industries, anionic surfactants (AS) have been shown to contaminate the natural environment. Therefore, the detection of trace amounts of AS in environmental samples is of great interest. Here, we report a novel fluorescence quenching method for the determination of trace AS, specifically, sodium dodecyl sulfate (SDS), using 1-(5-naphthol-7-sulfonic acid) -3-(4-pheny-lazophenyl)-triazene (NASAPAPT). Under optimum conditions, the degree of fluorescence quenching is linearly proportional to the concentration of SDS from 2.08×10-8 to 8.67×10-7mol L-1 with a detection limit of 8.35×10-9mol L-1. The proposed method exhibits high sensitivity and selectivity, yet it avoids the use of toxic organic solvents and tedious solvent extraction procedures. It has been applied to the determination of trace SDS in both natural water and industrial samples with recoveries between 99.04 and 103.58%. Results indicated that the hydrogen bonds formed between NASAPAPT and SDS played an important role in the detection process and that the π→π* transition was crucial for fluorescence of the NASAPAPT complex.
摘要：
In the paper, Authors separately used analytical hierarchy process, expert scoring method, principal component and BP network to establish the weights of ecological vulnerability evaluation Index system in the Hengyang Basin as a case, and used hierarchical-comprehensive index -clustering model, principal component-comprehensive index-clustering analysis model, expert scoring-composite index-clustering analysis model, BP artificial neural network model to evaluate separately the reality vulnerability in 2000. The results shows that study area are moderate weak, and the results broadly similar. Authors think that Principal component and artificial neural network model can avoid subjective factors, and taking the way of the expert group judgment is to reduce the error of ecological vulnerability assessment. With the impact of global change and the strengthening of fragile ecosystems, China has carried out many researches and practices on vulnerability assessments[1,14]. Although Vulnerability assessment in many ways, not yet formed a unified evaluation method, this paper draw on previous evaluation methods based on [1,11], using AHP, principal component analysis, BP neural network and expert scoring method on quantitative assessment and analysis, then clustering the results by comparison to determine which method to evaluate the most accurate. Authors analysis the Hengyang Basin reality vulnerability in 2000, attempting to explore a more suitable and easy erosion in hilly areas degraded fragile vulnerability assessment method.

摘要：
Six new 3d-4f heterometallic coordination polymers, {[Ln4Cu2(INAIP)8(H2O)15]·14H2O}n [Ln = La (1), Pr (2), Nd (3)] and {[LnCo0.5(INAIP)2(H2O)2]·2H2O}n [Ln = Tb (4), Dy (5), Yb (6), H2INAIP = 5-(isonicotinamido)isophthalic acid] have been synthesised and characterised by single crystal X-ray diffraction analysis. The results of structural analyses showed that 1–3 are isomorphous showing two-fold interpenetrated three-dimensional (3D) coordination framework, while 4–6 have the same non-interpenetrated 3D structure with 2D (4, 4) lanthanide-carboxylate layers. The results revealed that the different transition metal centres have great influence on the structures of the resulted complexes in this system. In addition, thermogravimetric and magnetic properties of 1–6, and photoluminescence of 4 were investigated.

摘要：
The enterprise value network is the commercial carrier for the socio-economic to operate effectively, but the Qudden stress?or Disaster? wh ich makes the enterprise with the vulnerability appear crisis finally, often occurs in the internal and external surroundings of enterprise. When it comes to the examples that Leiman Brothers, the Chinese Sanlu milk, etc., it still makes people feel fearful now. This paper will aim to study the formation, excitation, diffusion barrier of, in order to provide a theoretical basis and methods of decision-making guidance for enterprise.

摘要：
Hardware tasks scheduling is the effect of reconfigurable system performance of important factor. This paper presents a VLSCA algorithm which considers the placement according to the vertex position of hardware task and the adjacent units numbers of temporal dimension. At the same time, this algorithm introduces the compactness of task in three-space as an important index of choosing reasonable placement, which make the task more compacter, reduce the waste of system resources and promote management efficiency. Simulation results show that, with other existent scheduling algorithms, this algorithm has higher chip utilization and task accept ratio.

摘要：
To solve the incremental updating of association rule, this paper proposes an effective and simple updating algorithm based on list. This paper analyses this algorithm and compares with the Apriori algorithm and the FUP algorithm. This algorithm makes full use of the previous mining information and the efficiency of the insert and delete of the list. The algorithm scans the original and the updated database only once and achieves new association rules. This paper proved that the mining time and the result integrity of this algorithm are better than the traditional association rules by experiment.

摘要：
In order to assess the cities' human settlement, this paper proposes a new method according to the elements of niche suitability by the following: (1) the author selects meticulously 25 leading indicators what can reflect the best coupling between the reality niche and the best approximate niche; (2) the author sets up a new quantitative model of multiplies indices using niche suitability on assessing the cities' human settlements. By the way, the indices those the author uses to set up the model are form the economical, social and environmental niche respectively. The new method and the model are used to assessing the Heng Yang City of Hu Nan Province in China in order to take an example for its effect. With the help of the SuperMap-GIS software in his experiment, the author acquires a thematic map of Heng Yang Cities' human settlement, the results of this experiment display that this method and its model are very practicable for assessing a cities' inner human settlement. By the results of this paper, the author expresses his viewpoints for promotion the cities' human settlement that this paper does a research.
