The results indicate that both have well-developed nasals, frontal, opisthotic, and squamosal bones, but they have no orbitosphenoid, basisphenoid, pseudomesia bar, or supplemental maxilla.

研究结果表明：2种鱼均有发达的鼻骨、额骨、后耳骨和鳞片骨，上颌口缘由前颌骨构成，犁骨上具齿，上枕骨与额骨相接，左右顶骨分离，无眶蝶骨、基蝶骨、伪头中骨和辅上颌骨。

The recoery rate was calculated as follows;(JOA score at follow up_preoperatie JOA score)/(17 _ preoperatie JOA score) _ 100,15 and the surgical outcomes were classified into four grades based on the calculated recoery rate; excellent: recoery rate 75% or higher, good: 50–75%, fair: 25–50%, and poor: lower than 25%. Ealuation was made on radiographic findings, including the range of motion and the jaw diameter (a measured line from the posteroinferior corner of the ertebral body to the anterior aspect of the subjacent lamina) at the adjacent leels in group A and the affected leels in group B and the spinal canal diameter at the C4 leel in both groups. The C4 leel was chosen for this measurement, because the spinal canal is usually narrowest at this leel.

恢复率如下计算；（随访JOA评分-术前JOA评分）/（17-术前JOA评分）*10015，按计算的恢复率将手术结果分4级；优：恢复率75%或更高，良：50-70%，中：25-50%，差：低于25%。X线片结果评价，包括活动范围和颌直径（从椎体下后角到下邻椎板前方的测量线）在A组相邻水平与B组受影响水平及两组C4水平椎管直径。C4作为该侧量的选择是因为通常在此平面椎管最为狭窄。

Objective: This study aimed to evaluate the clinical value of digital pantomogram in identification the position of gnathous unerupted supernumerary teeth.

目的：评价数字化断层片在颌骨埋伏多生牙临床定位中的应用价值。

Compared with the Biopsy and postoperative histological result,the coincident rate (of malignant and benight tumors) is 96.4%. According to the cytological examination, 6 cases (3.1％)are of false negative result, 1 case is of false positive result. In close combination with clinic,strict puncture,...

细胞学假阴性诊断6例(3.1％)；假阳性诊断1例(0.5％)；针吸细胞学诊断口腔颌面部肿瘤时，只要密切结合临床，严格穿刺技术、准确足量的取材，重视涂片中出现的特征性粘液，综合分析，不失为一项简便、快速、经济、可靠、实用的诊断方法。

Objective To investigate the effects of anchorage control in bimaxillary protrusion correction by straight wire appliance.

文章摘要：目的研究支抗控制在滑动直丝弓技术矫治双颌前突畸形中的作用。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
