1.In this paper it is given a more effective formula about the direction angle of the main plane in the plane stress state.本文给出了平面应力状态下主平面方位角的一个更为有效的公 2.To introduce the principle and method for drawing 3-D graph with the compuer and for checking up with the...
PURPOSE: To simply correct a bearing with a simple constitution by processing the difference of horizontal magnetic field components measured by two applied magnetic fields, and indexing two correction coefficients. CONSTITUTION: When the bearing θ of a compass having a magnetometer which has means ...
as VariantCalculates geodesic reverse azimuth (in degrees) based on one point, bearing (in degrees) and distance (in m) using Vincenty's direct formula for ellipsoids.Note: by default azimuth from point 1 to point 2 at point 2 is returned. To obtain azimuth from point 2 to point 1 pass...
1.Especially the computing formula of azimuth resolution is corrected so as to meet the wide band situation.传统SAR的分辨率公式在超宽带信号和大转动角度的成像情形下不再适用,故通过分析转台成像的点扩展函数,分析了SAR成像的方位向分辨率,特别是考虑了相对带宽对分辨率的影响,提出了超宽带信号下方位向分辨率的...

The ratio of normal-to-shear fracture compliances, approximate to the product of two ratios of shear-to-compressional (S-to-P) wave velocity and normal-to-tangential fracture weakness, has been treated as an indicator of fluid content for an oil-bearing reservoir with aligned fractures. ...
A system of algebraic equations is obtained, from which analytical expressions are determined for calculating the azimuth bearing θ, elevation bearing β and the initial phase of the signal φ0 according to defined matrix trigonometrical formulae. The bearing β is determined after finding the ...
By using the measured unbalance results on the two trimmed planes on a vertical hard bearing double-plane dynamic balancing machine, the dimension and direction of couple unbalance can be found. An azimuth angle formula for the principal axis of inertia is derived and is solved by usin...
