After a European Union directive obliged European telecoms companies to "unbundle the local loop"—jargon for granting rival firms access to the copper wires running into homes and offices—prices for fixed-line telephone calls fell in Germany by more than anywhere else in Europe.

一项欧盟法令责令欧洲各大电信公司实行"本地环路分类计价"——该术语表示给予竞争企业使用联接家庭和办公场所线路的许可。在此之后，德国固话资费的降幅超过了欧洲其它地区。

通过丙烯酸高碳酯与马来酸酐二元共聚进行胺解反应得到一系列新型高凝原油降凝剂，并进行筛选，从中选出丙烯酰高碳胺与共聚物结合后的降凝剂降凝效果最好，凝点降幅大于10℃；进一步回归出加剂和未加剂原油的全粘温方程，方程呈对数关系。

Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

结果］UV-B处理导致叶绿素、可溶性蛋白含量以及含水量都降低，且存在剂量效应，30μW/平方公分处理的降幅大于15μW/平方公分；UV-B辐射处理对类胡萝卜素含量的影响与花青素相同，均表现为先下降后上升的趋势，2种剂量间差异不大；2种剂量的UV-B处理均抑制了PSⅡ的电子传递，尤其是处理2 h的抑制作用最大，4、6和8 h的抑制作用有所缓解，且存在剂量效应；2种剂量的UV-B辐射均抑制了叶片的光合速率，随着照射时间的延长抑制效应加大；高剂量UV-B处理对膜系统的损伤较大，低剂量UV-B处理结果不明显。

The same condition of reduction was also showed 12.34% reduction of the thorax acceleration value from 42.76g to 37.48g. Research NO.3 :The purpose of this research is to study the applicability of car seats for spastic paralysis children. Emphasis was placed upon the static anthropometrical measurement clinical evaluation experiment, and questionnaire survey for backward-facing and forward-facing children car seats in CNS, especially for the 9-18kg spastic paralysis children.

子题二︰本研究提出缓冲设计来降低头颈部的伤害之研究﹐透过前导实验和后期之实物前向式冲击试验证明与对照组比对，可降低头部和胸部加速度，分别降幅为30.19%和12.34%，因此证明缓冲设计提供较好的头颈部伤害的防护率。

The industrial experimental results showed that magnesium consumption coefficient decreased 13.6%(from 1.591KgMg/KgS to 1.375KgMg/KgS when desulphurization value was ≥0.016%) after bellmouth height-705mm, inclination of lance-11 °, carrier gas flow rate-35Nm~3/h and lance level-2150mm were adopted in industrial production.

通过工业试验，采用优化后的喷枪结构参数和工艺参数，镁消耗系数明显下降。当脱硫量≥0.016％时，镁消耗系数由1.591KgMg／KgS降到1.375KgMg／KgS，降幅达13.6％，效果明显。
