The first regards art and the appreciation of art as means to some recognized moral good, while the second regards them as valuable not instrumentally but as objects unto themselves.

答案 46。或者，人们可能会认为艺术具有负面的影响，像柏拉图在《理想国》一书中所认为的那样，艺术会影响那些接触它的人，使其堕落，或起不到教化作用。

As the primary factor, alkabinity should condition were acquired. As the primary factor, alkabinity should be below 12g/L; the desulfurization effect is optimum when the ratio of tannic and sodiumm metavanadate was 1.5-2; the high absorption temperature is unfavour for desulfurzation 30~40癈 was proved to be effective through experiments.

并得出碱度是影响其脱硫效率的主要因素，总碱度控制在129几以下比较适宜；拷胶和钒在脱硫过程中只是起催化作用，且得到二者比例满足1.5一2时，脱硫效果最佳；温度对脱硫效率的影响主要是在较高温度下会促进副产物 NaZSZO3的生成，所以脱硫反应器中的温度不能太高，经实验证明一般控制在30一40℃。

3In the normal space tensile,after controling the influence of density, the variation ofmicrofibril angle had a decisive effect on L MOE and longitudinal tensile strength of D333A wood microtome section; the Correlation coefficient between microfibril angle and L MOE became significant at 0.05 level for D1123A wood microtome section; the Correlation coefficients were all unsignificant between microfibril angle and L MOE and between microfibril angle and longitu- dinal tensile strength to D1223A wood microtome section.

正常间距拉伸中，控制密度的影响后，微纤丝角的变化对D333A组微切片纵向MOE和抗拉强度的变化起着决定性作用；对D1123A组微切片纵向MOE的相关系数达到0.05水平上显著；对D1223A组微切片纵向MOE和抗拉强度都成负相关关系，但都达不到显著水平。

One brightness ' phoenix unreal demon ' can give what the person goes up with spirit to comfort only, cannot remove the action of what essence.

一辉的'凤凰幻魔'只能给人以精神上的安慰，起不了什么实质的作用。

The stellate reticu-lum and the dental follicle of the underlying permanent tooth seems to be important for the deciduous root re-sorption. However, primary teeth without a permanent successor eventually exfoliates as well. Our current understanding on the underlying mechanisms is slim.

继承恒牙的牙囊和星网状层似乎在乳牙根的吸收中起着重要作用，而继承恒牙先天性缺失的乳牙根吸收最终仍会发生，其机制目前尚不明了。

By comparing the contribution of Zhang Jiebin with that of the physicians before or after him, it can be concluded that Zhang Jiebin was the keyman in the development, perfection and spread of the theory of Yin- Yang jaundices, and his work was the turning point for the theory of Yin- Yang jaundices from b...

比较张介宾(1563-1640年)和他前后的医家对阴阳黄理论的贡献，可以得出结论：明末张介宾在阴阳黄理论发展、完善和传播中起了关键性作用，他的工作是阴阳黄理论由不被重视转而成为黄疸主流理论的转折点。

A survey published Friday in France found that 54 percent of French believe that reprinting the images in the European press amounted to unnecessary provocation.

周五在法国发表的一篇调查表明54％的法国公民相信在欧洲对于漫画的重新印刷起了不必要的挑衅作用。

The results corresponding hasbeen drawn a lot,however,studies on FRP Tubed reinforced concrete columns have been verylimited(The FRP tubes are used to transversly confine concrete,not bearing the axialloads).Based on experimental and theoretical analysis,the mechanical properties of the GFRPtubed reinforced concrete columns under axially loaded are researched.

而针对内置钢筋的FRF套管混凝土结构的研究较少(套管指FRP管不承受轴压力，仅起约束作用)，本文通过试验和理论分析，着重研究了GFRP套管钢筋混凝土组合柱的轴压力学性能。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
