In this paper, the process of the cleaner roasting of shaly coal was studied.

本研究对石煤清洁焙烧工艺进行了研究，发现钙化焙烧除可完全避免钠化焙烧过程中Cl2 、HCl等有害气体的产生外，石灰在焙烧过程中有很好的固硫效果。

MPR and VR were applied in the imaging post-processing. Results: All cases were divided into four groups according to the thoracic CT findings and pathologic results as follows:① spheral caseous pneumonia;② tuberculous granuloma;③ fibrous caseous nodule;④ Focal pulmonary consolidation with cavitation. The spheral lesion appeared inhomogeneous density (44/58). cavitation (14/58) or satellite foci (21/58). Contrast scanning was carried out in 31 cases, of which peripheral or ringshaped enhancement was seen in 15 cases, no enhancement in 9 cases and extensive enhancement was seen in 7 cases.

结果：依据影像学表现、随访结果和病灶的病理改变，将58例球形肺结核分为四种类型：①球形干酪肺炎11例，体积较大（最大直径3~5cm），边缘模糊或毛糙，可见晕征，无强化或环行强化；②结核性肉芽肿19例，软组织密度，形态规则或不规则，边缘清楚或光整，强化模式为均匀强化或厚壁强化；③纤维干酪结节14例，规则球形，边缘光滑锐利，内部密度不均匀，可见钙化，多无强化或薄壁环行强化；④结核空洞14例，干酪空洞或纤维空洞，内壁不光整，可见到引流支气管（2例）。

Results: findings on 2d us included: irregular shape or spiculate margin were in 163 of 168 (97.0%) breast cancer; heterogeneous and hypoechoic echoes were in 165 of 168 cases (98.2%); micro calcification were in 86 of 168 cases (51.2%). in cdfi, blood flow was 98.8% found. 151 cases (90.9%) were found perforating blood vessels.

结果： 二维超声中，病灶形态不规则或有蟹足样突起者占97.0%，病灶内部回声低而不均匀者占98.2%，其中有微钙化者占51.2%，彩色多普勒血流显像中血流信号的检出率为98.8%，其中90.9%有穿入性血流，阻力指数≥0.70者占78.3%。

Sonographic features included irregular shape, microlobulation, spiculated margin, halo, posterior attenuation, microcalcification, ductal distortion.

病变的超声征象包括：形态不规则、小分叶、毛刺、强回声晕、后方回声衰减、微小钙化、导管扩张。

Cells in medullary carcinomas of thyroid gland can appear very pleomorphic or spindled, but there usually are better differentiated cells with neuroendocrine fetaures with or without amyloid, calcification, and giant cell reaction.

甲状腺髓样癌的细胞可能显示明显的多形性和梭形细胞样，但通常有分化较好的细胞伴神经内分泌特征，伴或不伴淀粉样变、钙化和巨细胞反应。

Results Manifest of high resolution CT scanning: lobulation sign (91.3%); spiculatecd sign(87%); pleural indentation sign (78.3%); vascularnotch sign (54.3%); sign of air bronchus and vacuole (34.8%); spinose processus (32.65%); milling glass dens (10.9%); calcification (8.7%).

结果：HRCT表现：（1）分叶征（91.3%）；（2）毛刺征（87%）；（3）胸膜凹陷征78.3%；（4）血管集束征54.3%；（5）空气支气管征及空泡征34.8%；（6）棘状突起32.6%；（7）磨玻璃样密度10.9%；（8）钙化8.7%。

Objective To investigate the relationship between coronary artery calcification score and stenotic extent by spiral computed tomography and the degree of carotid atherosclerosis.

目的 探讨螺旋CT冠状动脉钙化积分与颈动脉超声在预测冠状动脉狭窄中的价值。

Qualitative assessment of the lesion and quantitative measurement were performed in both stenotic and reference segments.

根据斑块组成回声的不同，分为软斑块、纤维斑块、钙化斑块和混合斑块，后三者统称为硬斑块。
