Low concentration of NaCl solution could promote the growth on the shoot of seed germination. The growing length of roots and shoots of two halophytes treated by 100 mmol·L~(-1) NaCl reached the highest and the growing condition on shoots was best. Then some physiological and biochemical parameters including the content of Na~+, K~+, Ca~(2+), proline and plant leaf tissue water potential, the assays of membrane lipid peroxidation and antioxidant enzymes were determined with the two halophytic plants on salinity.

研究工作首先对盐爪爪和盐穗木在种子萌发阶段的耐盐性进行了比较研究，表明盐爪爪和盐穗木都是很耐盐的盐生植物，在种子萌发期，盐穗木比盐爪爪更耐盐；NaCl和等渗的聚乙二醇对种子的萌发都产生抑制作用，且PEG的抑制程度大于等渗的NaCl。

In the absence of organic solvent and phase-transfer reagent, the catalytic oxidation of cyclo- hexene to adipic acid with aqueous 30% hydrogen peroxide can be achieved in the presence of tungstic acid/acidic organic additive.

以钨酸/有机酸性添加剂为催化体系，在无有机溶剂、相转移剂的情况下，催化 30%过氧化氢氧化环己烯合成己二酸。当钨酸∶有机酸性添加剂∶环己烯∶过氧化氢=1∶1∶40∶176(摩尔比，钨酸用量为 2.5 mmol)时，使用有机酸性添加剂考察钨酸的催化性能，结果表明以钨酸/间苯二酚催化氧化环己烯的催化效果最优，反应 8 h 时己二酸分离产率达 90.9%、纯度为～100%；而不使用有机酸性添加剂时，己二酸分离产率只有 72.1%，产品纯度为 96.2%。

Results: Within-run CV 、day-to-day CV and total CV were 1.33%、1.42% and 2.01% respectively by iterant test; average recovery rate was 96.6%; anticoag-ulant、septic、uric acid and bilirubin under a certain concentration also did not interfere with the glucose re-sult in this method. Compared with HK method, the pertinence was Y =1.038X-1.172,r =0.994. The linearity studies showed the method was linear up to 20mmol/L.

The molecular weight of dextransucrase measured by SDS-PAGE was 170 kDa ,which was similar to the enzyme from Leuconostoc mesenteroides. The enzyme had an optimum temperature between 25and 30℃ and an optimum pH of 5.4. It was relatively stable in the range of pH 5.0 to 7.0, but the stability declined rapidly as soon as the temperature rose over 35℃.
