Slurry is a necessary material in high-speed railway pile foundation construction. A lot of waste slurry which is harmful to the eco-environment will be generated after the construction is finished. If the slurry isn’t disposed properly, it will cause serious pollutions to the environment. This paper analyses environmental impact of waste slurry through four aspects: surface water, crops, soil and wastewater treatment system etc. Finally, it gets the conclusion that there are four methods to reduce the environmental pollutions of waste slurry: the first one is using the environment-friendly slurry in pile foundation construction; the second one is raising the slurry use efficiency; the third one is decreasing the amount of slurry usage and the output of waste slurry; the last one is developing the more eco-friendly waste slurry treatment methods.

History Of

The article analyses the results of the historical research activities of productive meetings at the enterprises of Soviet industry in the 1920s-30s. Analysis of the historiography has allowed the authors highlighting the trends and stages of work study meetings. In the fi rst phase in the second half of the 1920s, the research focuses on the forms and methods of organisation of workers' self-government and its role in the life of enterprises. Subsequently, in the 1930s, the production meetings are considered as an element of socialist competition. At the third stage, in the 1950s-70s, historians focused on the role of production meetings in the development of political consciousness of workers. In 1980s-90s, interest in the study of this topic is reduced. At the present stage, due to the intensifi cation of the study of history of the working movement, the topic of production meetings has again become topical. The authors identify the tasks of further study of the history of production meetings.

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.
