Reparation of PBO was begun with the polymerization process in which composite salts that contained 4,6-diaminoresorcinol and terephthalic acid were dissolved in polyphosphoric acid and phosphorus pentoxide.

BO纤维制备：以4，6-二氨基间苯二酚的盐酸盐为单体原料，与对苯二甲酸混合，经过中和反应、脱色处理、干燥后制成复合盐；再以多聚磷酸为溶剂，添加五氧化二磷和抗氧化剂，经过预聚合反应制备出PBO聚合物；聚合物通过双螺杆挤出机进一步进行聚合，然后通过喷丝板挤出，在磷酸水溶液中凝固成型，经过洗涤、干燥等过程，最终卷绕成型。

The results showed that Kaidimycin was chemically neutral, macrocylic polylactones, stable and liable to dissolve into water and pyridine, slight to dissolve into methanol, ethanol and N-butanol, difficult to dissolve into ethyl acetate, acetone, benzene and chloroform. Chemical reaction of functional group of Kaidimycin showed that it had glycoside, amino acid and aldehyde, no reducing sugar, polypeptide and phenol.

凯地菌素属中等极性的、中性抗生素，极性纸层析结果与多烯类抗生素的纸层析结果相似：易溶于水、吡啶，微溶于甲醇、乙醇、正丁醇，不溶于乙酸乙酯、丙酮、苯、三氯化碳；对高温、光照和紫外处理有很好的稳定性；官能团反应试验结果发现，凯地菌素可能含有糖苷键、氨基酸伯氨基和醛基，不含有还原糖、多肽和酚基，高锰酸钾、浓硫酸反应与多烯大环内酯类抗生素的特性相似；并且依据纯品，采用生物法和分光光度法对摇床发酵液进行了效价的测定。

Three composites of the different fibers with epoxy resin matrix are prepared and the corresponding unilateral fiber reinforced winding ring specimens are fabricated. The mechanical poperties of the composites including tensile strength, modulus and three point interlaminar shear strength are tested.

据文献 [2 ]介绍，PBO(聚对亚苯基苯并双口恶唑)是含杂环的苯氮聚合物的一种，它是采用二氨基间苯二酚和对苯二甲酸在多磷酸中聚合、采用空气间隙湿法纺丝法进行纺丝而制得的。

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