面横裂

The internal breaking, the stress transmission process, the quality variation with the change of the transformation structure features and the continuous expansion of the work-doing resulted from the weak stress of the pulsation action lower than the fatigue limit.

发现变形砾石内部存在特殊的微裂隙组构，呈现出错裂-横裂-劈裂-爆裂-复裂-应力矿物等的复杂组合，其结构面特征反映出显微构造形迹的力学性质是互为转变的。

G. Lekhnitskii and the Hankel integral transformation are used, And thereby a solution of the Stress field and displacement field of an embedded penny-shaped crack lying in a transverely isotropic plane under the action of the uniform tension stress at the far end perpendicular to the crack surface is obtained.

本文利用对于横观各向同性体轴对称变形时应力函数解法的基本方程，并应用Hankel积分变换，求解了位于横观各向同性平面内的埋藏圆片裂纹在垂直于裂纹面远处均匀拉应力作用下的应力场和位移场，获得了与各向同性材料相同的应力强度因子，不同于各向同性材料的应力场和应变能释放率裂。

Key words macrocheilia; functional reconstruction

面横裂；功能性修复

Pollen morphology of six species were similar, all trisected circular shape in polar view, tricolporate. Observed under LM the ornamentation of exine is granular with spinules arranged sparsely and under SEM the basal part of spinule extend.

六种沙蒿的花粉较为相似，极面观均为三裂圆形，三孔沟，孔横长，外壁纹饰在光镜下表面颗粒状，在电镜下为排列较疏的刺，刺基外延。

Among them,5 were＜2 years old,6 with craniofacial deformity:small mandible andmandibular retrusion(5 cases),transverse facial cleft(1 case),Down's syndrome(2 cases),cerebral palsy(2 cases),chronic bronchitis(3 cases)and mucopolysaccharidoses(1 case).Nineteen patients with symptoms of snoring, mouth breathing,were diagnosised as OSAHS by polysemnographyand treated by tonsillectomy andadenoidectomy in hospital.All patients were closely followed-up.

全组患儿中年龄＜2岁者5例，伴有颅面部畸形者6例(小下颌、下颌后缩5例，面横裂1例)，Down综合征2例，脑瘫2例，伴有慢性支气管炎者3例，黏多糖病1例。19例患儿均住院行整夜多道睡眠监测并接受扁桃体和腺样体切除手术，并对所有患儿进行随访。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
