An intelligent predictive model of the ventilating capacity of the ISF is established and analyzed by the method. The simulation results and industrial applications demonstrate that the predictive model is close to the real plant, the relative predictive error is 0.72%, which is 50% less than the single model, leading to a notable increase of the output of plumbum.展开更多

However, Hong Kong has been a colony of the British Empire for 154 years and 11 months and it has been under Japan rule for three years and eight years. Hong Kong returned to China in 1997. Its special history has significant influence on the language development in Hong Kong. During the period of British Empire, the popularity of Christianity, the commercial usefulness of English and high prestige in the society have resulted in the widely spread of English.In addition, English-medium education is in a relatively high state under the colonial regime while Chinese-medium education to some extent is not emphasized. The government has ruled that if parents would like their children to be educated in a good government school, they need to receive English-medium education. Consequently, the majority of parents would like their children to be educated by English. Apart from that, English has a legal status as an official language during British Colonialism period in Hong Kong. Lastly, some scholars supported the existence of a new English variety in Hong Kong(Hong Kong English), but others do not believe that. The requirements of language policies and the process of language spread in Hong Kong could be explained using some theories such as‘linguistic imperialism',‘Kachru's concentric circles' and‘Schneider's five stages'. For instance, from Kachru's perspective, the development of English in Hong Kong could be placed at the beginning of the third stage.It will firstly demonstrate some primary language policies in Hong Kong before its‘Handover'to China. And then, it will show several significant language spread theories and focus on relating them to the requirements of language policies and the process of language spread in Hong Kong.展开更多

It realizes the sublation of theory and ideology by means of critical, explanatory and constructive logic, displaying a unique theoretical originality. Lenin＇s theory of imperialism offers a theoretical reflection on the development of capitalism and its historical trends; it is a practical response to the world structural contradictions arising from imperialism, an epochal reflection that vigorously explores and constructs the value claims of a new civilization and provides in-depth Marxist view of world history. The methodology and general principles of Lenin＇s study of imperialism are based on the materialist view of history. They are not out of date, nor are the propositions in his theory of imperialism, based as they are on research into monopoly. At the same time as it declared war on the values, systems and practices of the old world, Lenin＇s theory provided a completely new cognitive method, philosophical attitude and ideal values for the future society. This has become the precious wealth of mankind, wealth that transcends historical time and space.展开更多
