Methods:The changes of serum CYFRA21-1 level were detected by RIA method in 34 patients with breast benign diseasesˇ47 patients with protopathic breast cancer before and after their operations and 56 patients with breast cancer only after operations.

方法ˇ采用放免法测定 34例乳ˇ良性疾病患者术前、47例乳ˇ癌患者术前和术后 4周及 56例乳ˇ癌术后随访患者的血清 CYFRA21-1 水平ˇ进行对照分析。

In the patients with protopathic breast cancer,the level of CYFRA21-1 after the operation for 4 weeks was lower than that before operation and the difference of them was significant.

结论ˇ血清 CYFRA21-1 检测对乳ˇ癌特异性高ˇ但对乳ˇ癌术前诊断价值不大ˇ对乳ˇ癌转移复发的监测有非常重要意义。

Much coagulation coul d be found to be adhered to the wall of reaction vessel and mixer when this cros slinker was used for conventional emulsion polymerization whereas coagulation co uld be greatly reduced and no obvious bulking of particle size of the product wo uld occur when this crosslinker was used for microemulsion polymerization and do sage and proportion of emulsifier wer.

将此交联剂用于乳液聚合中，若采用常规乳液聚合方法，反应器壁及搅拌上会粘附有大量凝胶；采用微乳聚合的方法并调整乳化剂用量及比例，可大大减少凝胶量，同时使产品粒径无明显粗大化现象。

Ambient temperature self-crosslinking acrylic latexes were prepared through semicontinuous emulsion polymerization using 3 different polymerizable alkoxysilanes, i.e. vinyl tri silane (A172), Vinyl triethoxy silane and γ-methacryloxypropyl trimethoxy silane (A174). The hydrolysis of these siloxanes under different pH was characterized, and dependence of the latex and polymer properties on these siloxanes and their incorporated amounts in the polymers was studied.

使用三种含不饱和双键硅氧烷，乙烯基三硅烷(A172)、乙烯基三乙氧基硅烷和γ-甲基丙烯酰氧丙基三甲氧基硅烷(A174)为功能单体，采用半连续乳液聚合法制备了室温自交联丙烯酸酯乳液，探讨了硅氧烷功能单体在不同pH条件下水解情况以及其种类和用量对乳液及乳胶膜性能的影响。

Then,the seed-emulsion was respectively copolymerized with many kinds of acrylates to form the excellent silicon-acralyte emulsions.

探讨了乳化剂加入量、种子乳液量、乙烯基硅含量(Vi-D4用量)、活性物含量等因素对硅-丙乳液转化率和接枝率以及乳胶粒形貌和乳液粒径分布的影响。

The addition of formic acid inhibitted the growth of LAB at the early stage of the fermentation, decreased the production of lactic acid and the pH of the early stage of the silage and increased initially the growth of the yeast and mold but inhibitted the growth of mold after 5 days of ensiling.

结果表明：单独添加植物乳杆菌增加了乙酸生成量和总有机酸生成量，降低了乳乙酸比；单独添加戊糖片球菌减少了乙酸生成量和总有机酸生成量，提高了乳乙酸比；二者均延缓了pH值的下降速度。

To purify high purity lactoferrin from bovine colostrums,a fast separation technique was established by ion-exchange process.

从牛初乳中分离提取乳铁蛋白，建立快速分离纯化乳铁蛋白的工艺。

Micro-structures of latexes were studied and components of the core and the shell were discussed, then the forming mechanism was analyzed.

采用外来种子乳液聚合方法，用反应单体对外来种子聚四氟乙烯乳液进行浸泡、溶胀，然后引发聚合反应制得聚四氟乙烯改性的聚丙烯酸酯乳液。

The results show: there is no much difference between ME and EC on controlling the target insects in different stage; the quick-acting effects of EC is better than CS and WP.

结果表明：微乳剂与乳油相比，对靶标生物的各期防效差异不大；而微囊悬浮剂和可湿性粉剂与乳油相比，其速效性和持效性均不及乳油。

The RAFT controlled growth of hydrophobic block led to the formation of well-defined poly-co-polystyrene amphiphilic copolymer, which was able to work as a polymeric stabilizer (self-stability). Finally, very stable latex was prepared, having no visible phase separation for several months.

这种方法在超声细乳化之后得到细乳液之后，不需要进一步搅拌，在加热聚合条件下即可最终形成自身非常稳定的乳液，该乳液放置一年时间仍(来源：Ad8B6969C论文网www.abclunwen.com)保持稳定。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
