Fast reciprocating probe systems ( FRPS ) are widely used in some tokamaks, such as JT- 60 U, TEXT and DIlI-D. The parameters with high temporal-spatial resolution are measured for boundary plasmas using these systems. The FRPS on HL-2A is developed, which is composed of transmission bar, digital grating displacement system, electromagnetic valves, stepping motor and so on. The high-pressure gas from the electromagnetic valves controlled by trigger signals provides the power to drive the transmission bar forward or backward. Reciprocating distance is 8 cm with the maximum speed of 1.5 m·s^-1. 展开更多

To cope with the problem of tracking a human head in a complicated scene,we propose a method that adopts human skin color and hair color integrated with a kind of particle filter named condensation algorithm.Firstly,a novel method is presented to set up human head color model using skin color and hair color separately based on region growing.Compared with traditional human face model,this method is more precise and works well when human turns around and the face disappears in the image.Then a novel method is presented to use color model in condensation algorithm more effectively.In this method,a combination of edge detection result,color segmentation result and color edge detection result in an Omega window is used to measure the scale and position of human head in condensation.Experiments show that this approach can track human head in complicated scene even when human turns around or the distance of tracking a human head changes quickly. 展开更多

The development of an analytic solution in terms of laminate parameters is presented for contact stresses and joint strength in pin-loaded orthotropic plates. This involved the determination of complex stress functions required to compute stresses in terms of a set of unknown coefficients for the specified displacement expressions satisfying the prescribed boundary conditions. The assumed Coulomb friction between the plate and the pin was used to provide the solution and iteration was also used to determine the extent of contact region. The results from present study showed good agreement with the available results in literature for all the joint configurations evaluated. 展开更多

With the growing tension of port shoreline resource in Three Gorges Reservoir area, many wharfs can only be constructed on slippery stratum with poor geological condition, which means buckling failure occurs easily. FEM strength reduction method is used in analyzing slope stability of a wharf in Chongqing, and its accuracy is verified by comparing the acquired results with the computation of traditional limit equilibrium method. On this basis, the influences of reservoir water level variation, overload and backfill material behind the retaining wall, and soil share strength of wharf slope on slippery stratum are analyzed. Analysis shows that, there' s a most adverse water level in wharf slope, and the engineering proposals with a certain practical significance such as improve the drainage behind retaining wall, controll overload and improve the strength of backfill soil and subsoil are suggested. 展开更多

In this paper,the authors have made the following findings after the fitting of China's economic growth rate series using an improved STR model:since 1949,great changes have taken place in China's economic growth pattern but factor input remains to be the major source of China's economic growth,as reflected by the extensive pattern of economic growth;with the exception of capital,the marginal output of all other production factors has been on the increase,which suggests that the efficiency of China's factor allocation has been continuously improved;the marginal output of capital has been on the decline,which explains that the dependency on investment for economic growth has led to excessive investment;reform and opening up and reform of marketization have substantially increased the sustainability of China's economic growth.In addition,the authors have investigated the internal momentum of China's growth transformation and developed relevant policy recommendations. 展开更多

"~边"、"~面"、"~头"类方位词的产生与单音方位词的语义演变有关。当单音方位词的空间实指义变得抽象和虚灵,它们的表义也越来越依赖于别的成分,后附性越来越强。方位词的语义自足性不断降低,引起形式上新因素的加入和补充,产生了复合方位词尤其是后加"边"、"面"、"头"类方位词,最终导致了汉语方位词形式系统单双音节两分的局面。这两种形式方位词的不同语义特点也是后来发展演变的基础,单音节方位词逐渐走向虚词性或词法平面,而双音节方位词则具有更多的实词性,更为自由地出现在句子中。 展开更多
