Amoung 10 compounds (polyhydroxy substituted N-benzoylserotonin derivatives), compound 4 shows the highest number of ε. The ε of compound 4 is high up to 11.43 × 103㎝-1M-1, which is the 2.84 times of the ε of control group, octyl salicylate. Moreover, compound 4 can absorb all the wavelength if UVB (280 nm - 320 nm), so compound 4 can provide the best protection from UVB. Additionally, this study also discovers that the compound 5 not only can absorb UVB, but also can absorb UVA.

而本研究所合成之多羟基取代N-色洛冬宁苯甲醯胺衍生物（化合物1 ~ 10）莫耳吸收系数最高者为化合物4，其在波长306 nm的莫耳吸收系数达11.43 × 103㎝-1M-1，为对照组水杨酸辛酯的莫耳吸收系数的2.84倍，且化合物4的吸收波长涵遝蒤紖VB波长(280 ~ 320 nm)的范围，故化合物4能提供UVB波长的最佳防护；另外化合物5除了具有UVB波长的吸收外，还具有UVA波长的吸收作用。

The invention relates to a method for synchronizing at least one node of a bus system, which is operated with a predeterminable system clock period, whereby a local clock period and a reference clock period are given for the at least one node, and the reference clock period is synchronized with the system clock period. A local clock period, which is synchronized with the system clock period, of the at least one node is produced whereby linking the local clock period with a splitting factor, whereby the splitting factor represents a ratio of the reference clock period to the local clock period. The splitting factor for synchronizing the local clock period with the system clock period is adapted by adding or subtracting a adaptation value.

用于同步至少一个总线用户的方法，所述的总线系统用可预定的系统周期运行，由此为该至少一个用户给定局域时钟脉冲周期和基准时钟脉冲周期并且把局域时钟脉冲周期与系统时钟脉冲周期同步，其中通过把局域时钟脉冲周期与分配系数相关联的方式产生同步到系统时钟脉冲周期的、至少一个用户的局域时钟脉冲周期，其中，分配系数说明基准时钟脉冲周期与局域时钟脉冲周期的比例，其特征在于，通过加或者减一个适配值或者说补偿值，对用于把局域时钟脉冲周期与系统周期同步的分配系数进行匹配。

The respiratory pulsatility of flows in portal vein were studied,and the pulsatility index and the correlative index between the PI and the quantity of TR were calculated.

The 352 valid samples were analyzed by SPSS. The results showed there was no distinct corresponding relationship between the product attributes and reaction time. The different key attributes from questionnaire importance rating and the shortest reaction time standards were used to regressively analyze the results of customers' overall rating (such as overall satisfaction,objective quality, recommend intention).The results indicated that the coefficiency of regression of the special attributes chosen from reaction time to overall rating was distinct, while the coefficiency of the special attributes chosen from importance rating to overall rating was not. The main conclusions are: 1. Regarded attributes can be obtained by the reaction time of brand performance rating.

本实验的有效样本为352个，通过SPSS软件进行分析统计，数据统计结果显示，在品牌表现评价反应时与其重要性问卷评定结果的相关系数的检验中，并未发现品牌表现评价反应时与品牌属性重要性评定结果之间的显著相关；将由问卷重要性评价最高标准所得到的关键属性与通过品牌表现评价反应时最短的标准所选取的关键属性的品牌表现分别对消费者的总体评价结果（如&总体满意度&、&主观质量&、&推荐意向&）进行回归分析，发现通过品牌表现评价反应时方法选取的特殊关键属性（与问卷重要性评定法选取不一致的关键属性）的品牌表现对总体评价结果的回归系数显著，而重要性评定问卷法选取的特殊关键属性（与品牌表现评价反应时法选取的不一致的关键属性）的品牌表现对总体评价结果回归系数不显著。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
