The dose enhancement effects and decreasing effects caused by material inhomogeneity were studied quantitatively with a parameter named Dose Perturbation Factor, which was the ratio of the dose at a point in the heterogeneous phantom to the dose of the same spatial location point in the homogeneous phantom. It was showed that the degrees of the dose enhancement or decreasing depended on the energy of radiation, field sizes of the beamlets and compositions of the media. The dose perturbation for high energy X rays is greater than that for low energy X rays. At the same energy condition, the dose perturbation decreased when the field size increased. And the relationship between them was not linear.

模拟结果表明：在小射野情况下，异质组织界面处出现了较大的剂量跃变，剂量扰动效应的强弱程度取决于射线的能量、射野的大小和模体介质的不同等多种因素，高能X射线条件下的剂量扰动效应大于低能X射线条件下的剂量扰动；在入射X射线能量相同的条件下，剂量扰动效应随射野尺寸的减小而增强，并呈现一种非线性关系。

By setting different kinds of filters of various thickness values before the pinholes of camera and using the spectral sensitivity of the camera,multi-frame X-ray images of wire arrays Z-pinch implosions in different energy ranges were obtained. By analysing the relationship between the intensity profiles of corresponding frames and the spectral sensitivity of the camera,it is allowed to estimate X-ray photon energy range in local areas of images.

The use of an X at the end of a letter to signify a koss goes back to the Middle Ages,when an illiterate person signed his or her name to marked documents and contracts with an X (which in church lore stands for Christ)and kissed the mark in the pressence of witnesses to affirm his or her sincerity .

在信的末尾用X代表吻，这一做法可追溯到中世纪。那时候，不识字的人用X在文件或合同上签名，并且当着证人们的面吻这个记号以表明自己的诚挚。吻和X这个十字形符号变成了同义词。

Tz = 2Gk q 即 z = 2Gk q /T 40 Suppose the volume between membrane and the boundary plane is V, and we notice that 2 ∫∫ d x d y = M Then we have Thereby we have q qM V =∫∫ zdxdy =∫∫ dxdy = 2GTk 4GTk M 2 Gk = 2V q /T From τ zx =τ xz =, y z 2Gk τ zx /= y q / T τ z y =τ yz = x 41 Moreover, we get 设薄膜及其边界平面之间的体积为V,并注意到 2 ∫∫ d x d y = M 则有从而有由又可得 q qM V =∫∫ zdxdy =∫∫ dxdy = 2GTk 4GTk M 2 Gk = 2V q /T τ zx =τ xz =, y z 2Gk τ zx /= y q / T τ z y =τ yz = x 42 Adjust the pressure q of which the membrane is under, and make the rights of formulas,, equal to one, then we can gain some conclusions as follows:(1) The stress function of wringed pole equals to the uprightness angle of the membrane (2) The torsion M which wringed pole received equals to two times of the volume between the membrane and the boundary plane.
