脲基

NAA, CPPU and EBR all induced parthenocarpic growth together with active cell division and enhanced transcripts of cell cycle-related genes.

奈乙酸，N-(2-氯-4-吡啶基)-N-苯基脲和表油菜素内酯都能诱导黄瓜单性结实，加快细胞分裂和提高细胞周期相关基因的表达。

You will also characterize the semicarbazone by melting point determination.

你也要通过测定熔点以鉴定缩胺基脲。

Make up a 1.5-3% solution of your semicarbazone in 3 mL of ethanol.

Part D. Melting Point of Semicarbazone Derivative

D部份。缩胺基脲衍生物的熔点测定

Where α is the rotation angle read on the polarimeter, C is the concentration of the semicarbazone solution in grams per milliliter of solution, and l is the path length of the polarimeter tube in decimeters (these units are employed for historical, rather than rational reasons).

是在旋光仪中的旋转角的读数，C是缩胺基脲溶液的浓度，以每千分之一公升溶液中的公克数来表示，而l是旋光仪试管的通路长度，以分米表示(这些单位都是历史沿用下来的，而没有合理的原因)。

Measure the optical rotation of the semicarbazone derivative solution in the polarimeter, following the procedure outlined in the Techniques Manual.

用旋光仪测得缩胺基脲衍生物水溶液的旋光度。

Thiobarbituric acid was synthesized by sulfourea and diethyl malonate in sodium alcohol and 5-Arylidene thiobarbituric acid was prepared by the Knoevenagel condensation reaction from benzaldehyde and thiobarbituric acid.

采用丙二酸二乙酯和硫脲在乙醇钠存在下合成了硫代巴比妥酸，再分别采用固相反应和水相反应，由硫代巴比妥酸和苯甲醛经Knoevenagel缩合反应，制备了5-亚苄基硫代巴比妥酸。
