To bring about a shift in how Astro 101 is taught similar to that motivated by Hake's study of introductory-physics teaching, we conducted a national study in collaboration with instructors who agreed to use the LSCI, to determine the effectiveness of various teaching strategies in Astro 101 classes.

为了使天文学101的教学方法发生转变，使之类似于黑克在基础物理学研究中所推行的方法，我们跟同意使用 LSCI 的教师协作，进行了一项全国性的研究，以便确定在天文学101的课堂教学中各种教学策略的效果。

The front suture width of axis and atlas joints and the shift degree of dens were also measured.results: 13 cases with 19 bone broken points,the positions are at dens ,side plank of atlas,occipital,plank of axis,processus spinosus etc.23 cases with axis and atlas half dislocation.of which,16 cases were with pure dislocation,7 cases with rotating dislocation,11 cases were with swollen at the side of vertebra,2 cases with depressing of vertebral artery,5 cases with continued narrowing of vertebral canal.conclusions: ct has the advantage of quickness,safety and high density discerning,it can reveal details of acute axis and atlas damages,so it has great importance to treatment scheme making and to the prognosticate.

结果：13例共见19处骨折，部位分别为齿状突、寰椎侧块、枕骨、枢椎椎板、棘突等，寰枢关节脱位23例，其中单纯性脱位16例，旋转性半脱位7例，11例合并椎旁血肿，2例见椎动脉受压，5例继发性椎管狭窄。结论：ct具有快捷、安全、密度分辨率高等优点，可明确急性寰枢关节损伤细节，对制定治疗方案及估价预后具有重要作用。

The numerical result shows that the contributions from the interface optical phonon mode with higher frequency and the LO-like half space mode to the binding energy and the Stark energy shift are important and obviously increase with increasing hydrostatic pressure, whereas the interface optical phonon mode with lower frequency and the TO-like half space mode are extremely small and are insensitive to the impurity position and hydrostatic pressure.

数值计算结果表明，高频支界面声子模和类LO半空间声子模对于结合能和斯塔克能移的影响是主要的，且随压力的增加而显著增大，而低频支界面声子模和类TO声子模的作用则很小，且对于杂质位置和流体静压力的变化不敏感。
