Therefore, this article main research mentality is, divides into the Shakespeare tragedy in multitudinous feminine image Mary with the Eve two kinds, demonstrated these two kind of females in male power society behavior and the unfortunate bitter experience, thoroughly analyzes them the reason which persecutes, thus discusses obtains, formulates in the male power society under feudal morals and standard, female no matter is wants to the male power society to meet as an equal, or obeys the morals under the shackles actually unfortunate to consider has violated this moral standard, similarly is all difficult to run away the destiny which is punished by the male power society, Thus manifests the male power consciousness to the feminine deterrent strength and the lethality.

笔者认为，只有通过对莎士比亚的4大悲剧作总结和归类，进而得出结论，才能够对莎士比亚的女性观作深入系统的解释，对女性的地位和生存状况加以进1步的阐述和研究。因此，本文的主要研究思路就是将莎士比亚悲剧中的众多女性形象分为圣母型和夏娃型两种，展示这两种女性在男权社会中的行为和不幸遭遇，深入分析她们受迫害的原因，从而探讨得出，在男权社会制定的封建道德和规范之下，女性不论是欲与男权社会分庭抗礼，还是顺从于这种规范之下却不幸被认为违背了这1道德规范的，都同样难逃被男权社会惩罚的命运，从而体现出男权意识对女性的威慑力和杀伤力。

JNS sulfuric-acid-dew-point-resistance steel has been put into practical use in the construction of steel-covered chimneys of the following electric power-generating stations: Zou xian Power Plant （2 1000 MW）, Xiamen Songyu Power Plant （2 300 MW）, Fujian Nanpu Power Plant（2 300MW）,Shenzhen Power Plant （2 300MW）.
