curvature造句
31 Current surgical techniques also involve reducing the cornea curvature in a bid to correct short-sightedness.
32 They contain the usual coordinate singularity on the hypersurface but, for this class, this is not a curvature singularity.
33 Spaces with more than two dimensions require more than a single parameter to describe the Gaussian curvature at a given point.
34 She was a polio victim and only four feet nine inches tall, with curvature of the spine.
35 At various periods after the injection of endothelin-1, the stomach was removed and opened along the greater curvature.
36 For vacuum solutions, in these regions at most one component, either 4 or 0, of the curvature tensor is non-zero.
37 The mathematical singularity arises because the set of coordinates imposed everywhere is best suited to regions of small curvature.
38 This clearly indicates that, in these cases, the singularity in this region is a non-scalar curvature singularity.
39 The curvature tensor can be identified by using an approach that was introduced in Chapter 3.
40 This relation generalizes for all two-dimensional surfaces to become where K is again the Gaussian curvature.
41 There is therefore a fundamental link between the curvature of space-time and the existence of classical tidal forces.
42 Now, in practice the astronaut would not drift across like this as the curvature of the walls would be far less.
43 In this case either I or J must be unbounded, and a curvature singularity occurs.
43 Wish you can benefit fromand make progress everyday!
44 In this case only, the surface corresponds to a curvature singularity.
45 Thereafter, the specimens were carefully opened along the greater curvature, laid on and pinned out on a flat surface.
46 When is small compared with unity, the curvature is small and general relativistic effects are negligible.
47 Its relationship both to the Gaussian curvature of two-dimensional surfaces and to tidal forces is discussed.
48 However, this would not give a true distance unless the curvature of the ground was also taken into account.
49 The desirable rate of change of curvature will vary with a design specification.
50 Positive curvature of edges can be trimmed away, if necessary, to give straight edges in plan.
51 A more complete and compact description of curvature in n dimensions is embodied in the Riemann tensor.
52 The stomach was removed, opened along the greater curvature, rinsed in ice cold 0.9% saline and weighed.
53 This can not be a curvature singularity, since the curvature tensor on it is zero.
54 In order to extend the discussion beyond the sphere we must introduce a definition of curvature valid for any such surface.
55 Rats were decapitated and the stomach were removed, opened along the greater curvature.
56 Washburn contends the curvature of the Earth would put these mountains below the horizon.
57 Any curvature or flaw in the line of its keel must be countered by a rudder, with consequent loss of energy.
58 Calculation of the curvature of the center manifold shows that this periodic solution is an attractor.
59 Using an element of known direction of curvature one can thus conveniently determine the direction of curvature of another element.
60 One simple measurement reveals whether a two-dimensional surface is curved and determines the sign of curvature.
