In this experiment, we screen the major protective antigen gene-SOD gene of M. paratuberculosisin order to study the sensitive, specific diagnostic reagent and prophylaxis preparation, especially theDNA vaccine. The SOD gene was amplified from Mycobacterium paratuberculosis C-2 chromosomalDNA by using the PCR technique and cloned into pMD18-T Vector System. We gained a SOD gene of624bp.The recombinant clone was identified byα-complementarity, enzyme digestion and PCRidentification. The result indicated that the recombinant plasmid pMD18-T-SOD was successfullyconstructed. Moreover, through sequential determination and DNASTAR analysis between the clonedSOD gene of M. paratuberculosis C-2 and that of the M.paratuberculosis K-10 strain, the sequentialhomogeneity reached 99%, and the amino acid homogeneity reached 99.5%. The preceding analysisindicated that the SOD gene was very conservative in M. paratuberculosis.

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.

通过改性剂B对粘结剂自硬砂的性能影响试验发现，改性剂B能显著提高粘结剂自硬砂的强度，在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外，但在较高环境温度下，改性剂M均降低粘结剂自硬砂的强度，但是适量的改性剂M有利于改善自硬砂的抗吸湿性，而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显，电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后，在粘结膜裂纹处会形成一种绒毛状物质，该物质对裂纹具有愈合作用，这种绒毛状物质中具有改性剂M中的某种成分，且含量很高，由此说明改性剂M对提高抗吸湿性有利。
