Radiation transmission through a composite pure water layer of uniform and depth-dependent extinction characteristics

The paper describes the calculation of the beam solar radiation transmission across the uniform salinity upper convecting zone (UCZ) and the salinity stratified gradient zone (GZ), when the extinction coefficient is not only wavelength but also salinity-concentration dependent, assuming that the effect of scattering to be negligible. The results are useful in determining the effects of dissolved salt ions on pure water transmission, at least according to the existing measured data in the literature.

井下减速器传动方案分析

结合井下减速器的结构特点，分析了定轴轮系传动、2K-H型行星轮系传动、3K行星轮系传动、少齿差行星轮系传动4种传动方案，选择内齿作为输出轴的少齿差行星轮系传动方案更符合涡轮钻具的传动要求和井下工具结构特点。少齿差行星轮系的研制、开发、应用可降低涡轮钻具转速，提高扭矩，提高深井钻速。     

Construction of transmission lines above valuable standing timber

Problems with the construction of transmission lines above a forest are examined. Construction of lines above standing timber makes it possible to shorten the length of the route, eliminate the clearing of a continuous swath along the line, and reduce the volume of in-service work. To implement this solution, it is necessary to introduce changes and supplements to existing regulatory technical documents. __________ Translated from élektricheskie Stantsii, No. 10, October 2007, pp. 48–51.
