the radius of curvature is ___a. inside the lensb. the focal lengthc. twice the focal lengthd. half the focal length 相关知识点: 试题来源: 解析 答案C设抛物线方程为x^2=2py 符合该方程的平抛运动的参数方程为:y=1/2gt^2,x=vt 改写参数方程得:y=2gx^2/v^2 于是2p=v^2/2g 在最高点...
Radius of curvature depends on the diameter of the tube. From to possess the radius of curvature which is stretched it is possible the tube of a smaller diameter. As for plan, moment of inertia and elasticity of the tube you insert in consideration. With the purpose which it plans, A* ...

The cavity with linewidthκ/2π = 330 kHz, finesse\({{{\mathcal{F}}}=70\,{{{\rm{k}}}\)and focal spot waistwc = 48 ± 5 μm is built from a low and high finesse mirror (specified finesse of coatings of 37k and 126k) with a radius of curvature of 10 ...
Figure 2 shows the design of a guiding structure and the simulation of the auto-ponderomotive potential Ψ. Eighty-four electrodes are printed on each of the two chips and define an S-curve with a radius of curvature of RK = 0.535 m, such that the output of the guide is lateral...
all of the faces that are within the dimple. If the rest of the mesh is convex, you could do this by looking at vertices that are not part of the convex hull and all of the faces that contain these vertices. Once you have this information, calculation of the radius of curvature ju...

The giant linear strain gradient over 106 m−1(defined as ΔS) corresponds to a radius of curvature (r) much <1,000 nm, which is probably the biggest gradient attainable in long-range linear strains expect for the local strain gradients observed at ferroelectric domain walls and other...
