By analyzing the images of women in the male-dominated society in which women were only regarded as men's accessories or marginalized and sexual politics embodied in Marrow narrative discourses,it hints that Conrad was influenced by patriarchic ideologies ,and he characterized binary women in the gender construction and characterization ,and this sugg.

通过分析马洛话语下的女性形象，在父权思想占统治地位的社会，女性只能作为男性的附庸，或者被边缘化，作品中展现的性别政治观点，折射出作者康拉德受父权思想的影响，在性别的建构和人物的塑造问题上，塑造了二元对立的女性形象，体现了他的性别歧视。

Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides. The ν OO value ranged from 850 to 899 cm -1 varies regularly with the substituent on the phenyl ring.

合成了全氟和其它对位、间位取代的共10种过氧化苯甲酰，测定了它们的固体和溶液(溶剂为F113， CCl2FCClF2)的激光拉曼光谱，首次发现这类化合物中高度对称的过氧键有较强的特征谱带，即νOO在850至899 cm-1之间，并随取代基不同而呈现规律变化。

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.

通过X射线衍射和扫描电镜分析手段研究了聚环氧琥珀酸加入前后碳酸钙垢晶型的变化，在此基础上探讨了聚环氧琥珀酸的阻垢机理；考察了温度对聚环氧琥珀酸缓蚀性能的影响，根据Bockris置换模型，计算出中性水质中聚环氧琥珀酸在碳钢表面吸附的热力学函数，计算结果表明：聚环氧琥珀酸在碳钢表面的吸附是一个放热、熵增、自动发生的过程。

On the basis of analysis of different kinds of reservoir petrologic feature, porosity, rate of percolation, we can conclude that the reservoir physical characterization in most cases controlled by depositional facies.

通过对不同成因类型储层的岩石学特征、孔隙度和渗透率等方面的分析研究认为，沉积环境、沉积微相与储层砂体物性之间有直接的关系。孔隙度、渗透率在平面上的分布在很大程度上受控于沉积环境和沉积微相。

A trypsin inhibitor was isolated and purified from Phaseolus vulgaris, and partial characterization of PVTI was studied.
