NaF

基本解釋

Methods Rats were subchronically exposed to NaF, and fluoride concentration and cholinesterase activity in rat hippocampus were determined.
方法用氟化鈉對(duì)大鼠進(jìn)行亞慢性染毒，測(cè)定大鼠海馬中氟濃度及膽堿酯酶活力。
Methods Culturing the cell strain UMR106 in vitro, using NaF as the control medicine, we observed the effects of Sanxiantang on the proliferation of osteoblast like cells by applying the MTT assay.
方法應(yīng)用UMR-106成骨細(xì)胞株，采用體外細(xì)胞培養(yǎng)技術(shù)，以氟化鈉為陽性對(duì)照藥，用MTT法測(cè)定三仙湯對(duì)成骨細(xì)胞增殖的影響。
The optimal fermentation medium and conditions of mutant strain NAF-032 with a higher and stable yield of L-lactic acid were studied by orthogonal design theory.
運(yùn)用正交試驗(yàn)設(shè)計(jì)理論，對(duì)高產(chǎn)L-乳酸突變株NAF-032的最佳搖瓶發(fā)酵條件進(jìn)行了研究，確定了最佳的發(fā)酵培養(yǎng)基和發(fā)酵條件。

氟化鈉
The normal incisor color and the normal morphology of the ameloblasts were in the control group and the experimental group 25 mg/L NaF.
而對(duì)照組和25 mg/L氟化鈉組釉質(zhì)表面顏色正常,成釉細(xì)胞排列整齊。
化學(xué)
氟化鈉
Under the reaction condition of benzadehyde 0.03 mol,acetc anhydride 0.08 mol,NaF/K2C034.5 g,and reflexing time 40 min,the yield of cinnamic acid can reach 77.3%.
即半微量實(shí)驗(yàn)中苯甲醛0.03mol,醋酸酐0.08mol,物質(zhì)的量比比為1∶2的氟化鈉和碳酸鉀混合催化劑4.5g,回流40min后進(jìn)行水蒸氣蒸餾。在此條件下,可得到肉桂酸的產(chǎn)量為3.4g,產(chǎn)率為77.3%。
