The Selection of Foundation Type of Large Cross-Section Wire of Transmission Line Iron Tower in Mountain Areas

For difference of elevation of transmission line in mountain areas, special considerations are needed for foundation design and construction.Take double-loop wire of 2×400 and mixed voltage four-loop wire of 2×630 iron tower as analysis examples, material quantity and economy index of different types of foundation in mountain areas are analysed in this paper so as to provide inference information for electrical construction.

Some remarks on a recent Mössbauer effect study of the β-phase iron germanide

A Mössbauer study of iron germanide was published recently in this journal (Daniels, Moore, and Panda). The authors reported that they reproduced, by computer analysis, their Mössbauer spectra in terms of three six-line iron sites, rejecting our earlier results of several FeI and FeII sites identified from a model of statistical (binomial) distribution of vacancies on the iron-site positions (Fatséas, Dormann, and Brossard). We would like, in this paper, to make some remarks and also to present some of our unpublished results for eventual future discussions.

X-Ray Fluorescence Determination of Barium and Strontium in Geologic Samples

It is possible to accurately determine barium and strontium in a variety of geologic samples by the XRF method proposed herein after correcting for matrix effects. The first-order (I) titanium Kα1 line interferes spectrally with the barium first-order (I) Lα1 analytical line. Iron significantly absorbs the emitted strontium x-ray quanta. Both of these effects were investigated in detail and a method of correcting for them developed. Detection limit for both elements is about 10 ppm.
