He analysis of the category and function of TCB stress inducible proteins showed that different groups of proteins were induced by 5 mg L^(-1) TCB stress. They are detoxification enzymes (including esterase, aldo/keto reductases, and glutathione S-transferase), cell wall compound metabolism related enzymes (including UDP-glucose protein transglucosylase and GDP-mannose 3,5-epimerase 1), phytohormone metabolism and regulation related enzymes or proteins (including aci-reductone dioxygenase 4, beta-glucosidase, two members of pathogenesis-related proteins from family 10), primary and secondary metabolism regulative enzymes (including translational elongation factor Tu, cytosolic orthophosphate dikinase, triosephosphate isomerases, alanine aminotransferase, and isoflavone reductase).

Using acetone as a photosensitizer,and N3· as an oxidant by pulse radiolysis method,the induced oxidation of cyclic-Phe-His in aqueous solution has been also reported in this paper,results similar to the photoionization of cyclic-Phe-His have been found.

而具有亲电子性的丙酮能在该环肽的苯丙氨酸残基的苯环上抽取电子，形成320nm和410nm的特征吸收峰，求出了自由基的有关动力学参数，并用脉冲辐解动态吸收光谱法印证了上述结果。

In the program, on theoretically we have studied the effects of configuration, the arranged periodic length and the refractive index ratio on PBG using finite difference time dormain method; on experimental, we have synthesized monodispersed silaca microspheres with size of 150-320 nm by colloidal chemical methods. And 3D perfect photonic crystals were prepared using the evaporating of acetone self-assembling the monodispersed SiO2 microspheres on quartzes by and horizontal and vertical deposition methods.

在本项目的研究中，理论上我们应用有限时阈差分法研究了光子晶体光子带隙形成与空间构型、排列的周期长度及折射率比之间的关系；实验上，我们应用胶体化学方法制备了150-320 nm的SiO2胶体微球，以丙酮为挥发溶剂，通过水平重力沉积法和垂直自然吸附法制备了各种粒度、排列完美的面心立方光子晶体。

Product of glycolysis is two three-carbon sugars, called pyruvates, and some ATP, which supplies energy to the yeast and allows it tomultiply.

糖酵解产生的是两个3碳糖，称为丙酮酸盐，和一些腺三磷，这些东西给酵母提供能量让其繁殖。

The two pyruvates are then converted by the yeast into carbon dioxide(CO2) and ethanol (CH3CH2OH, which is the alcohol in beer). The overall reaction

两个丙酮酸盐被酵母放换成为二氧化碳(CO2)和乙醇(CH3CH2OH，也便是在啤酒中的酒精)。
