For ferric nanoparticles, at the optimum condition of pH7.4 sodium cacodylate buffer solution, the detection limit of bovine serum albumin is 6.6ng/mL and the linear range locate in 0.02-0.70ug/mL.

纳米铁在最佳试验条件下，即pH7.4的二甲砷酸钠缓沖介质中，BSA测定的检测限为6.6ng/mL，线性范围为0.02～0.70μg/mL。

Application of a few drops of Fixative No.1(2% glutaraldehyde in 0.1M cacodylate buffer at pH7.2) to the tissue before cutting into slices can prevent sticking and drying and initiate the fixing process. The air in the plant tissues prevent the resin to reach the organelles, which makes the fixation difficult.

Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).

简单的说，先用切刀制成100um的冠状脑切片，然后用含有4%戊二醛在0.1 mmol/L的二甲砷酸缓冲液(PH7.4)中固定1小时后，放在含有1%四氧化锇的0.1 mmol/L的二甲砷酸缓冲液中2小时，接着用蒸馏水冲洗后，放在1%的aqueous uranyl acetate中过夜，接下来用梯度酒精(至100%)脱水，然后用丙酮干燥，再用Durcupan ACM包埋，切成0.1um的超薄切片后用3%的lead citrate染色，随后用透射电子显微镜观察。

In Na2CO3-NaHCO3 buffer solution, the apparent activation energy and activation parameters for cetyl trimethylammonium bromide micelle-catalytic hydrolysis of p-nitrophenyl propionate have been measured, and the effects of inorganic salts (such as NaCl, NaBr and Na2SO4) on them have also been investigated.

在Na2CO3-NaHCO3缓冲溶液中，测定了对硝基苯酚丙酸酯的十六烷基三甲基溴化铵胶团催化反应的表观活化能和活化参数；考察了无机盐(NaCl， NaBr， Na2SO4)对该催化反应的影响。

The effects of cholic acid concentration and pH of the buffer on separation were studied, and the influences of organic additives such as methanol, acetonitrile, isopropyl alcohol were also examined.

该实验表明电化学检测同样可用于手性物质的分离，从而扩宽了电化学检测的应用范围，并为对映体的定量合成和纯度测定找到了灵敏的检测方法。
