If the dial indicator reads 0.14~0.3mm , it means the tooth clearance is right; You can also use a 15~20mm long and 0.5mm thick lead sheet or "∽"-shaped fuse . Put the sheet or fuse between the unengaged tooth flanks tha is between the convex surface of small bevel gear and the concave surface of the large bevel gear. Turn the gear, then the pressed thickness of the big lead sheet end suggests the normal tooth clearance of this site.

另一种方法是用长15~20毫米，厚0.5毫米的铅片或弯成"∽"形的保险丝，放入两齿轮非啮合的齿面之间（即小锥齿轮的凸面和大锥齿轮的凹面之间），转动齿轮，则铅片在靠近大端处被挤压的厚度即为该处的法向齿侧间隙。

Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.

目的 探讨非骨化性纤维瘤的x线表现以提高诊断水平。方法所有病例均摄有x线平片，分析经病理证实的8例非骨化性纤维瘤。结果临床症状轻，好发于下肢长骨干骺端或骨干，股骨4例，胫骨3例，肱骨1例。皮质型5例，表现为皮质内或紧贴皮质下的单层或多层透亮区，病变向骨内发展进入髓腔，周围有致密硬化带环绕，以髓腔侧明显；髓质型2例，病灶在骨内中央发展，显示为单房或多房透亮区，边缘有硬化，骨皮质菲薄，轻微向周围膨隆。结论 x线为最基本的检查方法，典型病例x线平片结合临床症状即可明确诊断。

This kind of flower has 5 big thick leaf, whole and corollaceous show vermeil, blaze is nodded a bit above, every grow about 30 centimeters, whole flower has 6-7 kilogram heavy, because this looks flowery and grand.

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

其中，高温糜棱岩主要矿物变形特征组合为：石英为长矩状或长条状单晶、组构为近X轴的点极密，长石为几乎完全重结晶的集合体，形成温度＞600℃，相当于高角闪岩—麻粒岩相，形成深度＞20km；中温糜棱岩主要矿物变形特征组合为：石英为多晶条带、组构为近Y轴点极密和以Y轴为旋转轴的小圆环带，长石发育核幔结构，形成温度为400～600℃，相当于高绿片岩—低角闪岩相，形成深度为15～20km；低温糜棱岩主要矿物变形特征组合为：石英发育核幔结构、组构特征为近Z轴点极密，长石以碎裂为主，形成温度＜400℃，相当于中低绿片岩相，形成深度为8～12km；碎裂岩则主要代表了地表浅层的变形。
