The diluent solution of glyoxylic acid and oxalic acid was used as the separation object.TOA (in n-octanol) was used as the solvent. The extraction characteristics of single acid and two-acid solution were studied,and the influence of pH and the concentration of complexing agent on the distribution coefficients were measured. The suitable mathematic models were proposed to describe the relationship between TOA and carboxylic acid based on assumed extraction reaction in organic phase.

Vitamin E is an antioxidant that helps neutralize superfluous free radical, which was generated by exposure to sunlight, pollution, radiation, pressure etc. In addition, it helps prevent arterial disease, lower the haemoconcentration, repair damaged tissue, and moisturize and nourish skin, delay ageing.

维生素E是一种强抗氧化剂，有助于中和人体因日晒、污染、放射物、压力等产生的过量自由基，可防止动脉疾病，降低血液浓度，修复损伤组织，滋润肤质，延缓衰老。

The inhibiting effect of low molecular weight chitosans with different molecular weights on 13 plant pathogenic bacteria such as Helminthosporium oryzae were studied by detecting the minimum inhibitory concn. and inhibitory circle.

方法］通过测定最小抑制浓度和抑制圈，研究不同分子量的低分子量壳聚糖对稻胡麻叶斑病菌等13个植物原病菌的抑制作用。

The photocatalytic degradation rate of heptene increased with increasing the initial concentration of sulfur dioxide, but maintained almost a constant beyond a certain concentration.

同时研究了庚烯和二氧化硫的初始浓度、氧气和水蒸气的不同含量及光强等因素对其光催化氧化降解的影响。

It was found that the heteropolar space charges in composites were more than those in pure LDPE; Field-induced-thermally-ionization appeared in microcomposite obviously.

本文采用电声脉冲法(Pulsed-electro-acoustic Method， PEA)研究了纯LDPE、不同浓度的Nano-SiOx/ LDPE和Micro-SiO2/ LDPE复合材料等在中等直流电场下(5-20kV/mm)的空间电荷分布。

It might be due to the increase during pregnancy in folate uptake capacity via altered hormone regulation. In pregnant women without folate supplement, levels of folate metabolites varied, which was associated with genotypes of MTHFR, MTR, MTRR, ALDH1L1, and AMT. The 5FoTHF/5,10CHTHF ratio is relatively low in pregnant women carrying heterozygotic SNPs of MTHFR, MTRR, ALDH1L1 genes. It may be as a maker for evaluating genetic effects on folate maintenance.

在未服用叶酸的受试者中，叶酸代谢途径的MTHFR、MTR、MTRR、ALDH1L1、AMT等基因型对於叶酸各代谢物的浓度均有显著性影响，而5FoTHF/5，10CHTHF在MTHFR、MTRR、ALDH1L1的5个SNP中发现具变异型配子的受试者有比值较低的趋势，可以作为单纯评估个体受到来自於基因型层面影响的依据。
