Meanwhile,The distributed pattern of PURF particles is observed by microscope.The results show that the bearing capacity of cellular columniation is evidently improved by the infilling of additive.With the increasing content of additive,the compress strength of PURF was effectively enhanced f...

实验结果表明，泡孔支柱处的增强剂加强了其承载能力，有利于压缩性能的提高；随着增强剂用量的增加，PURF压缩强度和模量先增加后降低，即增强剂用量处于最佳用量范围内时，PURF体现最好的压缩性能；并随着纯聚氨酯硬质泡沫塑料密度的增加，其压缩性能有显著的提高。

In order to optimize an effective combined preservative applied to the orange juice preservation, the authors studied the synergistic effect of biological and chemical combined preservative which contained Nisin, potassium sorbate, EDTA and sodium isoascorbate in preservation of orange juice compared to preservation effect of each aforementioned additive in individual use. Results show that the growth of microorganisms can not be inhibited completely using each aforementioned additive in single use.

By adding YJ-504 corrosion inhibiting composite concrete additive and adopting the match technique of slag powder and fly ash,the high performance concrete shows excellent properties of low Cl-diffusion coefficient and freeze-thaw cycles ;The property of corrosion inhibition on steel of YJ-504 corrosion inhibiting additive satisfies completely the demands of related standard.

采用YJ-504复合型混凝土防腐阻锈剂，辅之以矿渣粉和粉煤灰双掺技术配制的高性能混凝土，表现出优异的抗氯离子扩散、抗冻融循环破坏性能；YJ-504复合型混凝土防腐阻锈剂的阻锈性能完全满足相关标准规定要求。

Using B Grade bauxite as bone material and A Grade bauxite as powder,different binder composition castable for permanent lining fo fundish were studied,with cyanite and sillimanite as expansion additives and Zimujie clay as sinter additive and plastic additive.

以B级高铝矾土熟料为骨料，A级矾土熟料为基质料，同时加入蓝晶石、硅线石为膨胀剂，紫木节粘土为烧结剂、塑化剂，研究了分别采用硅灰、高铝水泥、水玻璃、复合结合剂等为结合剂的不同配方组成的浇注料。

The results show that the addition of cross-linker makes tensile strength of the material greatly increase. After the addition of dialdehyde starch, the tensile strength raises from 7. 2MPa to 13. 2 MPa. However, the strength of the material cross-linked by TDI greatly increases when the additive level is less than 10％ while the tensile strength of sample whose additive level is 20％ is even worse, which is mainly caused by the inner-flaw after cross-linking.

结果表明，交联剂的加入使材料的强度得到较大的改善，添加双醛淀粉后，材料的强度从原来的7.2MPa提高到13.2MPa，而添加TDI的材料在添加量10％以前强度有较大的提高，但20％添加量的样品的强度却很差，主要是由于形成的内部缺陷造成的。

Its steps include these:(1) purification of WPA;(2) neutralization reaction between purified WPA and sodium carbonate for the salt mixture of disodium hydrogen phosphate and monometallic sodium orthophosphate;(3) adjustment of the mixture's neutralizing degree with additive acid or alkali;(4) quick separation of crystal with additive organic solvent under continue stir;(5) polymerization of crystal under the high temperature for the high quality product of STPP.

其步骤为：(1)湿法磷酸净化；(2)净化后的磷酸与碳酸钠中和反应生成磷酸一氢钠和磷酸二氢钠混合盐溶液；(3)用酸、碱调节确定该混合盐溶液的中和度；(4)加入有机溶剂，通过不断地搅拌使晶体快速析出；(5)晶体经高温聚合，生成高品质的三聚磷酸钠。

The result showed that the variance of special combining ability was significantly better than that of the general combining ability in amount of cocoon crop and cocooning rate to newly hatched larvae, meaning that non-additive effect of these two characters was dominant in cross combinations, but additive effect of thousand-cocoon weight was dominant.

结果表明：除千粒茧质量外，产茧量和收蚁结茧率的特殊配合力方差显著地大于一般配合力方差，说明在杂交后代这2个性状的非加性效应占主导地位，而千粒茧质量则以加性效应为主。
