By the name of religion, numerous paintings, sculptures, buildings, songs, poetries are created, and their worldwide honor and worship come naturally from the religious believers' piety. Ever since the decline of religious power, it seems that work of art loses also its honorable position. But, just as art is liberated from the shelter of religious crown, it can return to its own Being, recatch the inner value of beauty, and reconstruct the religious value deeply rooted in the work of art and aesthetic experience.

然而随著宗教力量的失势，艺术作品虽然一方面失去神圣崇高的宗教地位，成为一般的事物；但另一方面，正由於失去了宗教光环的遮掩，才得以从外表簇拥的灿烂繁华，重返存在本身的质朴，拾回其作为艺术作品本身所具有的光辉与神彩，并因而重现其内在本有的宗敎价値。

Seven inactivated tetravalent vaccines of Riemerella anatipestifer,of which three (1#,3#,7#) employed oil-emulsion,two(4#,6#) employed propolis,two(8#,10#) employed aluminum hydroxide as their basic adjuvants,were developed and compared by the methods as follows:challenges were performed by homologous virulent RA strains to measure their protective abilities;indirect enzyme-linked immunosorbent assay was used to monitor antibody production;lymphocyte transformation test was performed to study the expression of cell-mediated immunity.
