The point doses at the inferior beam edge for the two energies were 31.2% and 32.4%, respectively. There were 47-54% dose increase for superior beam edge and 37.6-35.2% dose decrease for inferior beam edge, as compared to the 50% field edge dose with the static dose distribution. There were 8.5 and 7.5 mm range increase for superior beam penumbras and 5.5 and 4.5 mm range increase for inferior beam penumbras, an important result corresponding to treatment volume.

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用

In strictly, it is hard to make the light normal incident into the sphere, double refraction will take place in crystal sphere when a TEM〓 mode Gaussian beam oblique incident into the sphere, and the two orthogonal polarized beams are both elliptical Gaussian beam. The ellipticity and eccentricity of the elliptical Gaussian beam will change with the incident angle, and for a fixed incident angle, they will change with the shifting of incident beam waist position.

由于严格意义上的正入射较难实现，基模圆高斯光束斜入射晶体球后将在球内产生双折射，且球内偏振态正交的两束折射光都将是椭圆高斯光束，它们的椭圆度e和偏心度Δ随入射角的改变而改变，在入射角一定的情况下，入射光束束腰的移动也将改变这两束折射光的椭圆度e和偏心度Δ。

To make picture clear, the electron beam that must come out to be being hit from electron gun undertakes focusing is handled, let electron beam pass electron lens, be opposite with optical lens of beam of light collect action likeness, the electron beam assemble that opens scattering rises, get on fluorescent screen one shines again small spot, add the effect of scanning circuit, ability shows clear picture.
