测定

The bacterial bioplastic coating argument is the strongest, as there have been cases in which ancient textiles have yielded radiocarbon dates much younger than other artifacts in the same sites—most notably in the instance of mummy 1770 in the British Museum, whose bones dated 800 to 1,000 years older, according to the radiocarbon tests, than the textile in which they were wrapped.

细菌性的&原生体覆盖物&的争论来得更激烈，已经有案例，就是古代纺织品的放射性碳年代测定比其他同样大小的史前器物的年代要晚得多——最值得注意的例子就是1770年陈列在大英博物馆的木乃伊，根据放射性碳年代测定，骨骼的年代为800至1000年之久，它们都被包裹着。

这种检测特别包括测定细菌对抗菌素或生物抑制剂的敏感性，以及测定评估细菌的生长阶段和健康状况。

Borak added that the dosimeter is in the testing phase and hopes it will provide valuable improvements to radiation dosimetry in the coming years.

博拉克补充说放射量测定器还处在测试阶段，他希望未来几年该设备能更好的完善辐射剂量测定方法。

Monomeric percentage of conversion measured by bromination and average molecular weight measured by viscosity method are also carried out.

用溴化法测定单体转化率，用粘度法测定聚合物的相对分子质量。

objective the effects of anthocyanin pigment from maize purple plant on resisting lipid peroxidation were investigated.methods the inhibition of anthocanin pigment from maize purple plant was examined in vitro that autcoxudation of lecithin liposome system induced by fe2+.50 mice were randomly divided into 5 groups.vehicle and different dose anthocyanin pigment from maize purple plant were given respectively,and then experimental injury of mice liver was induced to make use of bromobenzene and the content of mda was determined in liver homogenate.results the inhibition rates of anthocyanin pigment from maize purple plant on linoleic acid oxidation was higher that of ascorbic ascorbic acids.the content of mda in homogenate in middle and high dose of pigment were significantly lower than that in low dose and the injured control group.there were no significat differences in the content of mda in homogenate between low dose group and injury control group.conclusion the anthocyanin pigment from maize purple plant have the capability to resist lipid peroxide.

目的 探讨玉米紫色植株色素抗脂质过氧化的作用。方法体外实验测定玉米紫色植株花色苷色素在fe2+引发的卵磷脂脂质体体系中抗氧化活性。体内实验，取50只小鼠随机分成5组，分别给予溶媒和不同剂量的色素，然后采用溴代苯致实验性肝损伤，测定肝匀浆的丙二醛含量。结果在由fe2+引发的卵磷脂脂质体体系中玉米紫色植株色素对脂质过氧化有明显的抑制作用，抑制率随样品的浓度增高而增大，并且明显优于抗坏血酸。在溴代苯致小鼠实验性肝损伤模型实验中，中、高剂量组的丙二醛含量均低于损伤模型组。低剂量组和损伤模型组比较丙二醛含量差异无统计学意义。

Methods Acid dye colorimetry was used in the determination with bromocresol green buffer solution as the color developing agent with absorbance was determined at the detection wavelength of 417 nm.

目的 建立脑脉通有效部位中总生物碱的含量测定方法。方法采用酸性染料比色法，以溴甲酚绿缓冲液作为生物碱的显色剂，测定样品溶液在417 nm波长处的吸收度。
