III Investigations of ferromagnetic alloy films by XMCD1. By using XMCD and SQUID magnetometry, the spin and orbital moments of Fe and Co in the Co_(0.9)Fe_(0.1)(50nm) are studied. Compared with single-element film, the spin moment of Co remains constant while that of Fe reduced from 1.98 to 1.63μB. The contributions of different elements in the film is, m_ : m_ - 10.5 : 89.5. The average magnetic moment (1.90μB) determined by XMCD is in agreement with that (1.82μB) obtained from SQUID measurements. Utilizing XMCD spectra in-plane element-dependent magnetic anisotropy in Co_(0.9)Fe_(0.1) films has been investigated. Apart from known field-induced easy axis during film growth, a soft axis perpendicular to it was observed, and hard axes are 66° away from the easy axis.

The distuibution of axial plane stubs and stub crossing points are non-uniform and quantity of them is not equal when the blade is made by using traditional design method of turbine. These are not benefit with calculating wood model and drawing. In this paper, to make blade wooden patterns is using blade mean camberline. This makes the wooden patterns meet the demand of the design and meet the shape of the runner blade. And this can agree with requirements of hydro and mechanical analysis and making the model of blade by using the numerical control machine. It has reference value to whole design of turbine.
