An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

根据使用40小时后的中间包工作层残衬结构分析，其侵蚀机理为：干式料对渗入熔渣产生化学过滤作用，增大熔渣粘度，在干式料/熔渣界面形成致密结构，阻碍熔渣的进一步渗透；随着反应的进行复合矿物中熔剂含量的增多，熔点降低，溶于熔渣形成低熔点的硅酸盐相，并沿着干式料中的钙镁橄榄石和镁蔷薇辉石等结合相向干式料基质中扩散渗透。

Impact of composition upon the cold flow properties for biodiesel was investigated with gas chromatography-mass and cold filter plugging point tester based on the theories of molecular structure and crystal growth. Biodiesel may be considered a pseudobinary mixture consisting of components, with high-melting-point saturated fatty acid methyl esters and with low-melting-point unsaturated ones.

上颌牵引成骨技术矫治腭裂继发重度上颌后缩畸形术后颌骨稳定性明显提高，3例患者术后A点前后向复发率仅为8％，垂直方向复发率为14％。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。
