The research of multi-attribute decision making from the perspective of loss aversion is becoming a new trend since error is the root of loss generated. First, for multi-attribute decision-making environment in the “error” question, the definition of error is given and the properties of the rules which are used to judge whether an error occurred are explained. Next, the error transfer laws are analyzed. And then, the concept of errorloss is given. Finally, the mechanism of errorloss arising from errors is analyzed from the view of attributive classification.

In this paper，numerical simulation, based on volume controlled method,is used to study and analyze the heat transfer characteristics in the electrode of spot welding for 22MnB5 steel. The study focuses on the field distribution of electrode temperature and cooling water. It also explores the factors influencing heat dissipation capability of electrode, such as the concave angle on the bottom surface of electrode cooling cavity, the distance between the cooling water pipe and the bottom surface, and the endface corner cut of cooling water pipe, upon which electrode structure is optimized. The results show that, in normal operation,the cooling capacity of the optimized eletrode has greatly improved and the total cooling time is 2 s less than that of the non-optimized one.

A new implementation method for single-phase shunt active power filter (APF) with single closed-loop control strategy is presented. The ideal compensation current instruction is deduced with single PQ theory, which applies with actual and virtual quartered single-phase current and voltage. Based on the ideal compensation current, the practical compensation current instruction is achieved with power predictive algorithm. Because the power predictive algorithm is adopted, the single closed-loop control strategy can be used in APF application. There is no voltage control loop in the implementation method, so the method has many favorable characteristics, such as easy designing, fast responding, strong robustness, etc. The different conditions of APF, such as startup, normal operation and load change, are also researched in the paper. The validity of implementation method for APF is proved by simulation and experimental results.

Anti-slide piles are a main measure to reinforce slope for slope stability engineering, in which soil arch is easily formed between piles. Soil arch supported by adjacent piles is assumed to be horizontal and usually kept in plane strain status in vertical direction. It studies the calculating method of the soil arch supported by side surface friction of piles, which is combined with soil mass gravity. Then the influence of the soil gravity on arch bodies is further investigated in the view of quantity calculation. The research results show that the arch body in soil mass if considered to be weightless,is very safe for design purpose, because the gravity stress of soil mass has an important strengthening effect on the soil arch bodies formed between adjacent piles.

This paper takes the soft soil in Zhongshan port area as the research object. Many physical and mechanical indexes obtained from the spot, laboratory test and in-situ test have been analyzed. The results, which are compared with the soft soil from Nansha and Pearl River Delta, indicate that the variation of the water content, void ratio, compressibility in here are lower than these in other places. But its mechanical characteristics are still poor because of its low bearing capacity. In order to understand the relationship between the indexes, the linear and nonlinear regression equations are established. This research shows that the correlations of void ratio, moisture content and dry density in this area are the best. By analyzing the water content, void ratio, compression coefficient and cohesive force in different places in Zhongshan port area to describe the longitudinal variation curve, the curve shows that the soil indicators of the longitudinal change rule have regional differences. The results can be used for reference in the engineering construction in this area.

In order to explore the role of Notch1 signaling pathway in ERα-induced proliferation of NCI-H23, this research treats non-small cell lung cancer cells with E2, DATP or siRNA and analyzes the proliferation and protein expression of NCI-H23 by MTT, colony assay, PI assay and western blotting. The results show that E2 can enhance the proliferative ability with the proportion of NCI-H23 at S phase 1.33 fold of the controlled group. The expressions of Bcl-2 and PCNA in E2-treated cells are higher than the non-treated and Bax expression is decreased. The proliferative ability of DATP combined with E2 treatment declines evidently with P＜0.01 and the cell proliferative proportion 0.66 time of E2 group. With the obvious increase of BAX expression and the decrease of cell viability, before treatment with E2 transfection Notch1 siRNA in NCI-H23, the results show that ERα expression is lower than the controlled siRNA. Thus it draws the conclusion that Notch signaling affects the E2-stimulated cell proliferation and the inhibition of Notch signaling can impair the influence of E2 in NCI-H23.
