Fourty-five cases of Cupid's Bowvariation from 500 randomized lumbarvertebral films and 4 from 41 lumbarvertebral specimens were found.TheX-ray features arising from parasagi-ttal dual-concavities of the lower end-plate of the vertebrae were observedand classified into three grades.Itsclinic importance lies in avoidingconfusing with pathological defect ofvertebral endplate.The incidence,pa-thogenesis and differential diagnosisare discussed.

本文随机抽出500例腰椎片发现弓形椎变异45例,41个腰椎标本发现4个。对这种椎体下终板的对称性双凹形变异,所引起的X 线异常投影进行了观察、分级和鉴别.特别指出临床的重要性是避免与病理性椎体终板缺损相混淆。笔者结合国外首位报告文献,对发生率和发生机制进行了探讨。

The paper deals with the basic principles of the pulsed square wave AC MIG/TIG welding power source.It has a square static characteristic curve and a new "double concave" welding current waveform.The specially required dynamic characteristic has been studied and achieved.This power source may be used satisfactorilly in the AC MIG welding without any arc stablizaer.

主要介绍双凹波形脉冲氩弧焊电源的工作原理。电源采用方框外特性,提出了一种新颖的双凹形电流波形作为电源的静特性,并研究了电源动特性的影响及其控制。试验表明,此电源可以用于交流MIG焊,不加任何稳弧措施即可实现电弧稳定,工艺性能良好。是一种发展前景广阔的弧焊电源。

Objective To evaluate both fossa - condylar - meniscus positions and meniscus morphological change in patients withskeletal and dental class Ⅲ malocclusion in order to find out whether these two types of malocclusion were related to internal derangements of TMJ and whetherthe variation of TMJ structure was similar at the same type of malocclusion. Methods 39 pretreatment orthodontic patients were examined on right and left TMJ with corrected lateral cephalometric radiographs. Bilateral TMJ relationship of fossa...

Objective To evaluate both fossa - condylar - meniscus positions and meniscus morphological change in patients withskeletal and dental class Ⅲ malocclusion in order to find out whether these two types of malocclusion were related to internal derangements of TMJ and whetherthe variation of TMJ structure was similar at the same type of malocclusion. Methods 39 pretreatment orthodontic patients were examined on right and left TMJ with corrected lateral cephalometric radiographs. Bilateral TMJ relationship of fossa - condyles were observed with subjective evaluation, linear and areameasurement. 10 from 39 patients' meniscus positions and morphological change were imaged with 0. 5 - T sagittal magnetic resonance imaging system on right and left TMJ. Results 1. The variations of condylar - fossa positions at the sametype of malocclusion were not similar. 2. Skelctal and dental class Ⅲ paticnts demonstrated significantly more anteriorly positioned condyles. 3. Most of meniscus positions were in normal range, few of their positions were in slightly anterior rangeand all of the shapes were normal with concavoconcave. Conclusion The structure of TMJ with skeletal and dental classⅢ malocclusion was normal, so these malocclusion did not have any strong groups association to TMD.

目的为探讨骨性和功能性Ⅲ类错与颞下颌关节紊乱病之间的关系。方法利用矫正薛氏位片对Ⅲ类骨性错19人,功能性错20人的双侧颞下颌关节的髁突居关节窝的位置进行评价,并依据髁突居关节窝中的位置(前移、居中、后移),从上述两类错中各选5人做双侧颞下颌关节矢状位核磁共振扫描,观察关节盘的位置及形态变化。结果每一类型错髁突居关节窝中的位置并不一致,但位置分布比较集中,Ⅲ类骨性和功能性错髁突明星居关节窝前位,当髁突居前位或中位时,关节盘位置在正常范围且形态为正常的双凹形,髁突居后位时,关节盘位置在正常范围或轻度前移,形态也都表现正常。结论Ⅲ类骨性和功能性错颞下颌关节结构基本正常,与颞下颌关节紊乱病关系不密切。
