The 1.5 ℃target imposes stricter requirements on China＇s nuclear power. Considering the available nuclear power plant sites, nuclear power layout, equipment manufacture ＆ supply, nuclear power plant construction capacity, supportive operation ＆ management talents, investment, cost effectiveness, and public acceptance, the achievement of the development objectives of nuclear power in China considering the 1.5 ℃ Target is difficult. However, it is possible if favorable decisions and policies are made.展开更多

Therefore more and more attention has been paid to MHW pollution. Shanghai, as an industrial and economic center and an international metropolis in China, has a vast industrial system spanning a multitude of sectors, which generates MHW not only in a huge magnitude but also in a large variety of types from complicated sources, resulting in severe pollution. In 2003, the production of MHW in Shanghai is about 3.96 × 105 ton, involving 33 indices. Most of MHW in Shanghai is treated and disposed of, but a significant portion is not handled properly and effectively. This paper carries out in-field investigation on the current status of MHW production and treat- ment in Shanghai, and puts forward scientific proposals that Shanghai should facilitate cleaner production and minimize haz- ardous waste; strictly enforce hazardous waste registration system, strengthen monitoring the certified enterprises; strengthen intent disposal center construction and realize hazardous waste reclama- tion; accelerate establishing the technical criteria and the man- agement policy, promote the research and development on the treatment and disposal technology, and strengthen information management, thus realizing integrated management on MHW pollution.展开更多

Achieving the 1.5 ℃ target imposes high requirements on global emission reduction. Nationally Determined Con- tributions of all Parties are far from the 1.5 ℃ target, and conventional emission reduction technologies and policies will also have difficulty in fulfilling this task. In this context, geoengineering is gaining interest in the international arena. The Paris Agreement includes afforestation, carbon capture, utilization and storage, and negative emission technologies such as bio-energy with carbon capture and store. All of these techniques are CO2 removal technologies that belong to geoengineering. Solar radiation management, which is highly controversial, has also attracted increased attention in recent years. Although the outline of the IPCC Special Report on 1.5 ℃ does not include a specific section on geoengineering issues yet, geoengineering is an unconventional technical option that cannot be avoided in research and discussions on impact assessment, technical options, ethics, and international governance under the 1.5 ℃ target. On the basis of analyzing and discussing abovementioned issues, this paper proposes several policy suggestions for China to strengthen research on and response to geoengineering.展开更多

The Introduction section presents a description of the construction and function of the UCTD, and the experiments conducted in the South China Sea on board the R/V Dong Fang Hong 2 in July 2007 and August 2008. The UCTD system, with pressure and temperature sensors in the probe, is con- veniently portable, cost-effective and environment-friendly. It is hopefully suitable for future cruises. An intercomparison based on regressing with the experiment temperature data from both SeaBird plus911 CTD and the UCTD showed that the standard deviation is 0.88~C and the correlation coefficient is 0.96, achieving the goals set for the current oceanography uses. In the hydrodynamic experiments, the descending velocities and depths were calculated for different ship speeds. A pulling test was designed with a tensiorneter to measure the magnitude of the pull. The maximal tension of the line was found to be 66.2 kg, which is far lower than the bearing limit of the Hollow Spectra line. Finally, some improvement suggestions are put forward for future experiments and production.展开更多

The software can calculate the size and locate the situations of the isolated melts. According to the liquid shrinkage of each isolated melts and the standard parameters of risers in the database, the riser’s situation and the size can be identified intelligently as long as the riser’s shape is selected. 3-D software and simulation analysis of CAST soft/computer aid engineering(CAE) software show that the design of the riser and the running system is feasible.展开更多

Economic development Globalization has promoted the deep integration of information and industry, put forward higher requirements for the transformation and upgrading of manufacturing industry, relying solely on the rich labor resources advantages can continue to serve Shanghai economic development. Fierce international competition, ＂labor shortage＂, energy security, labor standards and other issues have led to a gradual increase in labor costs.展开更多

The common motto is the idea of gift. The gift of the death of Christ in the economy of salvation is the target of Derrida＇s deconstruction. Anselm himself enables this. However, there is in Anselm＇s theology of Trinity a metaphysics of the gift of being and of being other, elaborated with regard to the procession of the Holy Spirit. And it is possible to submit the original gift of the Holy Spirit to the same kind of deconstruction, that is, of economic reduction, to which the gift of the death of Christ had been submitted. But both the construction and the deconstruction of the theology of gift resort to the same kind of analogy procedure. And economy does not enable us to think the gift as purely as does theology.展开更多

Firstly, this paper analyzes the development status of equipment manufacturing industry in Shanghai, and then uses DEA to analyze the efficiency of technology innovation capability of equipment manufacturing industry in Shanghai. The results show that the equipment manufacturing industry in Shanghai has stronger overall drawing ability, and besides, the technology innovation ability of the transportation equipment manufacturing industry is weak, other equipment manufacturing sub industries have relatively strong ability of technological innovation. This paper analyzes the shortcomings of the transportation equipment manufacturing industry and gives guidance and puts forward corresponding suggestions and measures.展开更多

This is a loss felt by all Chinese as a psychological sense of hollowness, a loss of identity, made worse by the seeming inaccessibility of the ancient Chinese wisdom to the modern Chinese mind. It is clear that at some historical point China suffered an extreme psychological blow sufficient to traumatise it at the threshold of reflective thought, unable to look inwards any more. The paper identifies that point as the utter devastation wrought by Kublai Khan and the Mongols 750 years ago. What devastates reflective thought is wilfulness, the insistent focusing of all attention and energy on external, material things, and Kublai Khan was wilful in the extreme. What confirms this as the crippling point is that, in response to Kublai Khan＇s Mongol invasion the Chinese, over time, not only completely altered the geography of China itself, moving their capital to the North （Beijing）, but have ever since fought to establish as ＂China＂ all the territory over which Kublai Khan ruled. China is clearly not free of Kublai Khan＇s shadow. But even more precisely, in the process of doing this--and showing their own wilfulness--in building the Forbidden City in Beijing they built it in the shape of the Chinese metaphysical model of the universe, the Chinese version of the Tree of Life metaphysical glyph But it has an error in it. And the error is precisely that in where it places things, it makes what would have been the attributes of reflective thought subservient to wilfulness. The model itself thus shows the hollowness of the Chinese mind from that moment on. The outer form--the ＂appearance＂---of the ancient wisdom was still there. But the content--the ＂substance＂--of it was not. And with no reflective thought, true creativity disappears.展开更多
