X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

In order to achieve a tradeoff between vectoring and unvectoring state, the proposed parameters of DTN are: Z=3~4, secondary injection flux is about 3%, cavity divergence angle is about 10°, cavity convergence angle is 20°~30°, injection angle of secondary is about 30° by counterflow injection.

Results there are 22 affected patients (10 males and 12 females with approximately equal sex ratio) and the mean age of onset was 16 years old.fifteen patients had positive family history.the major symptom experienced was itching.keratotic papules were invariably present in our patients and mixed pattern with seborrheic plus flexural involvement was the commonest phenotypic variation.all of them had acral signs; 36.36% patients had oral mucosal lesions.lesions were most frequently found on face,ears and back of ears,neck.focal acantholytic dyskeratosis with corps rounds and grains were the usual histopathological findings.
