In the first scheme an auxiliary atomic level is needed. While in the second scheme an additional classical driven field is used, and the multi-ion cluster states can be generated by one step. Both the schemes are insensitive to thermal motion of the ions, all the facilities used in them are well within state of the art.展开更多

The results show that the sedimentation velocity of interface between unclassified tailings and water after the addition of NPA increases by 10-20 times, the sedimentation mass fraction of unclassified tailings at the bottom of vertical sand silo is up to 64%, the solid particle content of waste water meets the national standard, and the side influences of NPA can be removed by the addition of fly ash. The industrial test result shows that the system, the addition manner and the equipments are rational, and the vertical sand silo is used efficiently. This developed system is simple with large throughput, and the processing cost is 2.2 yuan(RMB)/m3, only 10%-20% of that by mechanical settlement.展开更多

A process involving agglomeration controlled precipitationis considered in which secondary nucleation occurs simultaneously with primary nucleation. The determinantequations for the existence of multiple steady states are developed and the multiplicity boundaries dependent on thephysical and kinetic properties and operational parameters of the process are obtained by resolving these determinantequations. The number of steady states in the precipitator for various multiplicity regions is determined and thelinear stability of these steady states is analyzed by using the Routh criterion.展开更多

It is found that the probe gain can be generated even when no probe field is applied to the system, we attribute this result to the existence of the external field. By comparing with the conventional probe gain, the probe gain without the probe field is enhanced greatly because of the absence of the population inversion term.展开更多

Chintz has adopted a new, highly compatible, multipronged approach. Judgingfrom current agricultural and rural policies, factors like capital, labor and land will continue to interact and revolve. The transformation of China＇s rural land tenure system is at a critical posifion in the overall strategy of developing tile rural economy. However, rural institutional reform will inevitably be constrained by the path and pattern China＇s industrialization, urbanization and agricultural modernization take. Creating a new pattern of urban and rural socioeconomic integration requires reform and improvement of rural grassroots governance structure. The interaction and reconsolidation of the factors have again become intertwined with the superstructure of rural society and will inevitably affect the direction and pace of rural grassroots governance structural reJbrm. Protecting the economic interests of farmers while respecting their democratic rights will always be at the heart of agricultural modernization.展开更多

In World War I and World War II and even the cold war period, it obtained a good performance, so its importance is self-evident. However, with the high-end development of modern science and technology, Intemet transmission replace and people＇ s self-cognition awakening, the psychological warfare dissemination means of simply by posters to expand influence has become obsolete, but it doesn＇ t mean that we don＇ t need these means. Most of the time, in such a complex social environment and interpersonal environment, the most original and most straightforward method is the most likely weapon to move people＇ s thought. This paper reviews the posters in World War I, World War II and cold war period in disseminating psychological warfare success to illustrate the importance of this means in wartime psychological warfare dissemination process. At the same time, it analyzes the feature of modern dissemination psychological warfare, mining new communication means with traditional publicity method and re-constructing the function application of posters in dissemination psychological warfare and other business expanding.展开更多
