查询词典 eruption

Results maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years). this inclination increased with age. the logistic regression showed that the sagittal inclination of the first molar is a predictor of the eruption of the third molar.

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。logistic回归结果显示第一磨牙的轴倾度是第三磨牙萌出的一个预测因子。

The fluorescent bands formed in both mesial and distal cementum.Conclusion The results don't support the point that transseptal fibre or force of molar eruption makes teeth migrate mesially; the mesial migration of teeth is related with the reconstruction of alveolar bones and the stress distribution in the bones.

实验结果不支持越隔纤维作用或磨牙萌出力作用引起牙齿近中移动的观点；牙齿近中移动与颌骨内应力分布有关，牙槽骨改建的量与牙齿近中移动量呈正相关。

Methods: Fifty-fix adolescents were chosen and divided into first premolar extraction and nonextraction groups, with 30 and 26 patients respectively. The pretreatment and posttreatment panoramic radiographs were taken. The indexes of third molar eruption space, distance from third molar to occlusal plane and the length of mandible were measured and analyzed.

选择56例上下颌第三磨牙均存在的患者进行方丝弓正畸治疗，按照第一前磨牙拔除与否分为拔牙组（30例）和非拔牙组（26例），利用术前术后曲面断层片对患者上下颌第三磨牙萌出间隙、第三磨牙与胎平面的距离以及下颌长度进行测量分析。

Objective: To observe the expression of the osteoprotegerin mRNA in the occlusal tissue during the tooth eruption.

目的：探讨骨保护素mRNA在牙齿萌出过程中方组织内的表达。

Objective:To observe the expression of the ostcoprotcgerin mRNA in the occlusal tissue during the tooth eruption.

目的：探讨骨保护素mRNA在牙齿萌出过程中方组织内的表达。

They may be of soft or firm consistency. The surface may be smooth or rough. If capped by scales, they are known as squamous papules, and the eruption is called papulosquamous.

This paper studies the correlation between the maximum height s of the Plinian volcanic eruption columns and mass flux of the volcanic eruptions according to measurement data acquired from active volcanoes around the world.

Plinian式火山喷发柱最大高度是研究火山喷发对环境、气候影响时空范围的重要物理学参数，在分析了影响Plinian式火山喷发柱最大高度诸因素的基础上认为，火山喷发的质量通量是反映火山喷发柱最大高度最有效并且在实际中可以进行测量的参数之一，以此为基础，利用目前实测的火山喷发柱最大高度的数值与火山喷发质量通量的结果，建立两者的相关方程为：H＝0。
