Local recurrences mainly occurred in the nasopharyngeal cavity and the skull base bone. Dosimetric analysis showed 9 cases of in-field failure, 4 cases of marginal failure, and 2 cases of out-field failure. For the 6 cases of marginal and out-field failure, the main reasons of recurrence were low dose area in target volume due to not strictly following the guidelines of defining field limit, or inappropriately estimating the involved regions of lesions.

Content question: there is no space in the universe, we observed with space is matter and field components space, the expansion of space is substances and substances in the expansion of the field, all moving substances and substances will be in a field-the-field sport, including light and electromagnetic waves, like automobile from the disconnexion in the same way, there is no absolute vacuum of space, there is no absolute coordinate system, all substances campaign has been relative motion.

内容题要：宇宙是没有空间的，我们观测的空间是物质和场物质组成的空间，空间的扩大也是物质和场物质在扩大，所有运动的物质和场物质都会在一个场上运动，其中包括光和电磁波，好象汽车离不开路一样，不存在绝对真空的空间，也没有绝对坐标系，所有物质运动都是相对运动。

On the basis of experimental research, this thesis applies 2-dimensional non-linear finite element method to the analysis of transient temperature field on the section by means of relatively high precision triangular element of six joints. When the temperature field is analyzed, finite element reseaus are divided in space field and finite difference reseaus are divided in time field, and then the program is compiled. The computing results are in good agreement with the test data. It indicates that the program is stable and precise.

The author analyzed the current state of the declining performance of Chinese athletes in traditionally advantageous track and field events, and considered that the backup talents for traditionally advantageous track and field events was short of supply for the following reasons: The serious difficult-job dodging ideology of local sports management leaders and the existing competition system have restricted the opportunity for current excellent athletes to temper themselves; blind training ideology existed in the training conception for traditionally advantageous track and field events; the coaching performance of coaches for traditionally advantageous track and field events was kind of poor.

摘 要：对我国田径传统优势项目下滑的现状进行了分析，认为原因在于田径传统优势项目后备人才乏人、地方体育管理决策层避重就轻思想严重、现行的竞赛制度减少了现役优秀运动员参加大赛磨练的机会、田径传统优势项目训练存在闭门造车现象、田径传统优势项目教练员执教水平的局限等。
