After cross - linked with phosphorus oxychloride the polarization cross of tapioca starch under polarized light has no distinct change in the different period of the biodegradation , showing that when the degree of cross linking is high starch biodegradation is very difficult 经三氯氧磷高交联后的木薯淀粉在微生物降解过程中颗粒的偏光十字变化不明显，表明一定程度的三氯氧磷交联会抑制微生物对淀粉颗粒的作用。
The microstructure of fly ash foamed concrete and the water resistance of magnesium oxychloride cement foamed concrete were analysed in virtue of sem method , at the same time , whose process to hydrate and carbonization resistance were analysed correspondly 借助sem测试手段对粉煤灰发泡混凝土的微观结构和氯氧镁水泥基发泡混凝土的耐水性进行了机理分析，同时对其水化过程及抗碳化性能也进行了相应的机理分析。
Fireproof board of magnesium oxychloride with good properties of high strength and water resistance was prepared by analysis of the compression strength and resisting the intensity of rolling over . the proper composition of magnesium oxychloride cement , stuffing , resin and assistant additions is 100 : 35 : 5 : 4 论文实验获得了强度高、耐水性好的氯氧镁无机防火板材料,其优化配比为:胶凝料:填料:树脂:各种助剂= 100 : 35 : 5 : 4 。
Authority reports that three national champions we hold now are the production of phosphorus oxychloride , the selling volume of 1 - phenyl - 3 - methyl - 5 - pyrazolone and the export volume in europe of triethyl phosphate . in addition , our p - methoxybenzoic acid has good reputation in japanese market 据国家权威机构统计：氧氯化磷在全国产量最大1 ， 3 ， 5 -吡唑酮在全国销售量最大磷酸三乙酯出口量最大对甲氧基苯甲酸在日本也有一定知名度。
Fireproof board of magnesium oxychloride has been attracted much attention and become the main part in the fields of inorganic building boards because of its attractive properties such as good fireproof property , mechanical strength , sound insulation , shake resistance , heat preservation and so on . but it also has its own defects of dehylogenation , deformation and poor waterproof , which limit its use and decoration 氯氧镁无机防火板以其轻质、高强、粘接性、韧性、隔音、抗震、保温、隔热、防火、防潮、防腐蚀、耐酸碱、防蛀、环保性能好、施工安装方便、施工劳动强度低、快捷、价格低廉等特点,而得到人们的广泛重视,成为国内目前市面上应用最为广泛的无机防火板材之一。
In this paper , the effects of fly ash , cement , lime , fine sands , foam agent , w / c ratio and additional agent on foamed concrete were studied by experiments , the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design , the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly , so the author selected them as independents to establish duality linear regression equations , the equations were quite ideal through the test of model summary r . moreover , the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete , the outcome showed that phosphoric acid has good effect on water resistance , and its appropriate quantity was found 本文通过试验研究了粉煤灰、水泥、石灰、细砂、发泡液、水灰比及外加剂对粉煤灰发泡混凝土性能的影响，采用正交设计试验方法得出了600级粉煤灰发泡混凝土的最佳配合比，同时发现发泡液和粉煤灰掺量对发泡混凝土的影响最为显著，因此，以二者为自变量建立了二元线性回归方程，通过全相关系数的检验发现方程较为理想。此外，还对氯氧镁水泥基粉煤灰发泡混凝土的耐水性进行了相关实验，发现磷酸有较好的耐水性效果，同时找到了其合适的掺量范围。
Phosphorus pentoxide is usual material and reagent in chemical industry , this product is widely used in the industries of medicine , coating auxiliaries , printing and dyeing auxiliaries , anti static additive , titanate coupling agent , phosphorus oxychloride , chemical . mainly used in producing high purity phosphoric acid , used as desiccant of gas and liquid , dehydrant of organic synthesis 五氧化二磷是化学工业中常见的原料和试剂，本品广泛用于医药，涂料，印染，化工等行业，主要用于制造高纯度磷酸，用作气体和液体干燥剂，有机合成的脱水剂，以及有机磷酸酯的制备。
The research progress and the facing difficulties of active / passive planar optical waveguides were systematically summarized and reviewed in this paper . zro2 - si02 binary oxide gel glasses and films applied for active optical waveguides were prepared by the sol - gel method with zirconium oxychloride and tetraethoxysilane as precursors . the paper has investigated the influence of the compositions of system and heat treatment temperature on the system refractive index in zroj - sioj binary oxide gel glasses 本文在系统综述有源和无源平面光波导材料研究进展、前景和面临的主要问题的基础上，应用溶胶?凝胶技术，以teos和zrocl _ 2 ? 8h _ 2o为先驱体，研制了用于有源光波导基质材料的zro _ 2 ? sio _ 2二元系统凝胶玻璃块材和薄膜。
