The ELISA titre was 1:2000.By cell fusion, 46 hybridoma cell lines were screened,and 10 lines were cloned with limited dilution method.16 lines secreting anti-bFGF monoclonal antibody were been developed, and 2 lines targeted fusion protein. Sensitive ELISA and dot-ELISA for bFGF was developed with this mAb. The detection limit of them were 0.1 ng/well and 0.5 ng/well. The expression level of anti-bFGF mAb by different rebuilt engineering cells were identified by western blot and to direct rebuild recombiment engineering cell. The dose and character of anti-bFGF mAb inhibiting bFGF biology activity were searched by 3T3 cell line. Searching 20 tissue of liver cancer, liver cancer cell lines and general tissue of liver, finding bFGF were highly expressed in tissues of liver cancer and liver cancer cell lines. Affinity chromatography purifying bFGF was set up by mAb binging CNBr-pepharose 4B, and the purification was 95%. We found that the titer of anti-bFGF antibody was very high in serum of neuropathic amyotrophia.

In a traditional total quantity distillation setup or a half micro-distillation setup, the separation and absorption of ammonia and constant volume must be done separately, so the analyzing program is complex and needs long analysis time. By the rapid azotometer (Type: NC2), the ammonia in the waste water could be analyzed through one step which includes separation, absorption and titration. Compared with the tradition analysis methods, the ammonia-N in waste water can be analyzed more quickly.

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.

在实验室进行了降低铁水中硅含量的实验，得到了铁水中硅含量的影响因素：提高二元碱度有利于降硅；增加渣中氧化物可降低SiO2的活度有利于降硅；Al2O3和SiO2不利于降硅；冶炼时焦炭中SiO2的挥发量随温度的升高而增多，使铁水中硅含量增加；随着滴落带高度的增加，铁水中硅含量不断增加。

The optimum formula was as follow: the fresh milk and emblic leafflower fruit juice mixed according to the proportion of 8:1, and 8.5% sugar were added; optimum compound stabilizers: starch 0.10%+pectin 0.025%+PGA0.05%; amount of latic acid bacterium: 5%; fermenting temperature: 42℃; time of fermentation: 2.5h.
