The soil problems in Shanghai were studied, including the salinity and nitrate nitrogen (NO -3 -N) concentrations, heavy metal pollution characteristics, and organochlorine pesticide (OCP) residual levels and polycyclic aromatic hydrocarbon (PAH) contents. Accumulation of NO -3 -N in vegetable soils was the most significant among different functional soils. Heavy metal pollution was significant in the samples collected from the sewage-irrigated land and roadside. The identification of the metal sources through multivariate statistical analysis indicated that Pb, Zn, Cu and Cr in urban soils were from the traffic pollutants; excessive application of fertilizer and irrigation were the main reasons for the metal pollution in agricultural soils; Ni in the observed soils was controlled by parent soils. OCPs could still be detected in farmland soils but degraded greatly in last 20 years after prohibition of their usage. PAHs with 2-3 rings were the main components in industrial soils. The concentrated PAHs in the investigated soils were likely from petroleum and coal combustion.展开更多

The parents earliest birth in the only child family, has now gradually entered the old stage. While the family lost their children for a variety of reasons, is facing a serious economic, spiritual and other pension problems now.This paper starts from the analysis of the present situation of the unaccompanied elderly in Shanghai, attempting to find a path to solve the problem, and then proposes to explore the establishment of unsettled old-age security related supporting measures and policies.展开更多

The construction of the study is composed by following aspects. The first aspect is the modelling of a structural system. As a typical example, a mega frame-core-tube structural system adopted by some famous super tall buildings such as Taipei 101 building, Shanghai World financial center, is employed to demonstrate the modelling of a computational model. The second aspect is the establishment of motion equations constituted by a group of ordinary differential equations for the analyses of free vibration and resonant response. The solutions of the motion equations （that constitutes the third aspect） resorted to ODE-solver technique. Finally, some valuable conclusions are summarized.展开更多

It is imminent to establish a system that can meet the long-term care needs of the disabled population, As a pilot city of long-term care insurance. Shanghai has a Fund for the long-term care insurance system. To compare and analyze the related elements of raising, service content and payment, combined with the experience ol long-term nursing insurance in foreign countries, and considering its application in community pension, it has certain reference significance for the design of long-term nursing insurance system in China.展开更多

But in the second, it is more important to achieve the functional area. New self trade test area covers the Lujiazui financial and Trade Zone, Jinqiao Economic and Technological Development Zone, Zhangiiang High Tech Park and comprehensive free trade zone, the state-level development zone has formed a respective unique function and mature operation mode, expanding area, the area co reform, the development of dislocation. In the special regulatory region, actively learn from international practice, to further intensify reform efforts, especially to explore the construction of offshore financing to adapt to the development of offshore trade environment, to become the highest degree of openness in the region. ＂The expansion of the Shanghai free trade zone will help to test the innovation of different industrial types in a wider range.＂展开更多

By selecting a highly sensitive structure of the fiber Bragg grating strain sensor, the performances of the sensors with three materials were investigated both numerically and experimentally. The strain sensitivities were 3.76pm/με, 3.02pm/με and 3.03pm/με, respectively. The linearity was better than 0.998. It provides useful information for developing sensors for the marine engineering.展开更多
