It was found that these two nutrients affected the growth of Chlorella significantly,and there were significant interaction between them.

结果表明，氯化铵和磷酸二氢钠对该藻增殖具有极显著作用，且这两种营养盐之间存在交互作用。

The influences of different surfactants (sodium dodecyl sulfate, sodium cholate and sodium deoxycholate), different electrolytes (sodium phosphate monobasic, sodium tetraborate and 3-cyclohexylamino-1-propane sulfonic acid), buffer pH and organic modifiers on the determination of sialic acid were studied.

其次建立了一种测定唾液酸的在线富集CZE法，该方法用40 mM磷酸二氢钠为缓冲溶液电解质，通过将样品溶解在乙腈：水=2：1的样品基体中，进样时间增加到100 s来达到样品富集的效果，并考察了样品基体中乙腈浓度和进样时间对富集效果的影响，研究了用硼砂或3-环己胺-1-丙烷磺酸作为电解质、缓冲溶液pH值和有机修饰剂的加入对唾液酸检测的影响。

Objective To observe the effect of menadiol sodium diphosphate induced mutation.

目的 观察甲萘氢醌二磷酸酯钠的诱变作用。

Then,in the bovine serum albumin buffer solution containing disodium hydrogen phosphate and citric acid,ferrite/polyacrylamide was added with crosslinker glutaraldehyde and then be enwrapped by BSA.

首先在反相微乳液体系中制备出Fe3O4/PAM磁性微球；然后在牛白蛋白的磷酸氢二钠-柠檬酸缓冲溶液中，以戊二醛为交联剂，加入Fe3O4/PAM微球，使蛋白质特异性吸附在微球上。

Disodium hydrogen phosphate dodecahydrates possesses the largest mass heat storage capacity among the low temperature phase change materials, which are classified as inorganic, organic and then: composites, yet it experiences phase segregation and super cooling when melting and hinders its application in latent heat storage system.

低温相变材料可分为无机、有机物及其复合物。十二水磷酸氢二钠(Na_2HPO_4·12H_2O)是其中质量储热密度最大的一种，但由于熔化时发生相分离，而妨碍了它的实际应用。

An ODS column was selected as the separation column at 25 ℃, and pH 4.50, 0.02 mol/L of trisodium citrate-0.05 mol/L sodium phosphate dibasic to methanol (95:5, volume ratio) without ion-pair at a flow rate of 1.0 mL/min.

该实验采用ODS柱，流动相为V(0.02 mol/L柠檬酸三钠-0.05 mol/L磷酸氢二钠)：V=95：5的溶液，用电化学检测器检测。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
