The length, width, axial gradient for the crowns,the heigh of gingival line,the width of anterior dentition and the ratio of crista marginalis of their teeth were measured and analysed in their photographs and dental casts after orthodontic treatment.

测量关于正畸治疗后上颌第一前磨牙和对侧尖牙的龈缘线高度和牙齿形态的6项指标：龈缘线高度、临床冠长度、宽度、单侧前牙列宽度、轴倾度和近远中边缘嵴比，进行两均数配对t检验，观察分析两组的差异。

The purpose of this study was to compare the apical leakage of different root canal sealers in combination with ObturaⅡthermoplasticized gutta-percha injection technique.

本研究以单根离体牙为研究对象，采用墨汁渗透、牙齿透明和扫描电镜观察等手段，评价ObturaⅡ注射式热熔牙胶配合使用不同的根管封闭剂时的根尖封闭能力，为该技术在临床上的推广应用提供实验依据。

Petrous apicitis is a rare complication of otitis media or mastoiditis, in which infection, most commonly by pseudomoas, spreads to the petrous apex.

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.

对幼苗根尖细胞学研究观察，获得单桥、双桥、桥断裂、落后染色体、三级、断片和微核等畸变类型；对已获得的小麦突变株，分别进行M2 代DNA分子的RAPD分析，结果发现DNA均发生变异，证明7Li+ 3 注入通过内靶核反应能够诱发小麦在分子水平上产生遗传变异。

Vatica guangxiensis and Altingia andersonii are dominant tree species of the upper layer in the community, which can be divided into A, B, C, D, E layers. and is mainly charactered by evergreen megaphaenerophytes and mesophaenerophytes with simple, chartaceous, entire, caudal mesophyll leaves. There are a lot of wooden lianas and epiphytes between layers.
