On Ernest Hemingway＇s Views about Women

Emest Hermngway is famous for his ＂masculinity＂ style in his writing. Meanwhile, he also describes female characters and their strengths and reveals his own sensitivity to gender issues. His early exposure to women is from his upbringing dominatrix. His failure on marriage plays an important role on his works. In his mind, women are the combination of angel and evil. They act elegantly and attract men＇s heart, but sometimes they are changeable. Catherine Barkley is a typical angel except her suspect. Catherine Bourne is an evil though she is charming. Brett Ashley is attractive, but she can＇t love whom she loves. That is a society without choice. Women＇s feelings attach to men. They show their right to love, to change. Even to escape the cruel reality. At the same time they know they can＇ t cast the society. Hemingway pays more attention on women＇s feelings in his writing. On the one hand, he respects women＇s elegance, beauty and view on love. He wants to get love and care from them. On the other hand, he holds in awe on women. He assumes women are changeable, and is afraid of being hurt. Hemingway＇ s mind is full of conflicts, and his love, hatred, sympathy belong to not merely male, but also female. No matter she is angel or evil, he can＇t help himself and his readers falling in love with these women of extraordinary beauty.     

Risks posed by obesity to body-surface narrowband wireless communication

Little work has been done on the effect of being overweight on the wireless narrowband radio propagation of wearable medical instruments. In this paper, by applying a finite-difference time-domain technique and a statistical learning method, the authors find that being overweight might be an obstacle to body-surface wireless communication. The findings have certain instructive meanings for those engineers who are designing on-body medical instruments for patients, especially those patients who are overweight.

Gender Difference in Learning Style

This article mainly focused on learning styles and its relative influence on language learning proficiency,as well as gender difference in terms of learning style.Through a literature review,I found many learning style models.Also,there were many variations among the students in use of these models.The acquaintances of learning style may benefit students and language instructors to adapt teaching and learning to individual differences among students.This can enhance education effectiveness.     

A Class of the Hamming Weight Hierarchy of Linear Codes with Dimension 5

The weight hierarchy of a [n; kI q] linear code C over Fq is the sequence(d1,… dr,… dk), where dr is the smallest support weight of an r-dimensional subcode of C. In this paper, by using the finite projective geometry method, we research a class of weight hierarchy of linear codes with dimension 5. We first find some new preconditions of this class. Then we divide its weight hierarchies into six subclasses, and research one subclass to determine nearly all the weight hierarchies of this subclass of weight hierarchies of linear codes with dimension 5.

解色散方程u_t=au_(xxx)的绝对稳定高精度半显式格式

本文对色散方程ｕｔ＝ａｕｘｘｘ的初边值问题，构造两个绝对稳定的半显式格式，其局部截断 误差为Ｏ（τ２＋ｈ４＋τ２／ｈ２），精度较高．     

自我概念和自我效能感对不同性别学生学业成绩的预测作用

主要研究自我概念和自我效能感对于不同性别学生的学业成绩是否有相同的预测作用。以往在对学生的学业成绩进行预测时,往往只使用学生自我效能感的得分或者是只使用学生自我概念的得分,但是本研究发现自我概念与自我效能感对不同性别的学生的预测作用是不相同的,自我效能感的得分对男生学业成绩的预测作用要比女生大,而自我概念的得分对女生学业成绩的预测作用大于男生。所以在进行成绩预测时,对不同性别的学生应该考虑使用不同的预测指标。

东海鳓鱼雌雄性状比较及其鉴别

本文对在１９８５－１９８７年间舟山近岸采集的鳓鱼雌雄个体性状作了比较分析。结果表明：除了吻长、叉长／体长等指标在雌雄间有显著差异外，其它指标均无显著差异。到了繁殖早期，雄鱼的体厚、成熟系数都显著地大于雌鱼，而肝指数却显著地小于雌鱼。本文还进一步用逐步判别的方法给出了鉴别雌雄的判别函数：ｙ＿１＝－６３４．８８０５＋１３７．４８４５ｘ＿１＋９０７．１５９８ｘ＿２＋７４５．８３６３ｘ＿３ｙ＿２＝－６２３．６２９８＋１２３．６８９２ｘ＿１＋８９４．３３４０ｘ＿２＋７６６．０１６６ｘ＿３式中ｘ＿１为吻长／头长，ｘ＿２为叉长／体长，ｘ＿３为体厚／体高，用４６个样品回代进行判别，得错判率为１０．９％     

生物阻抗频谱技术检测Wistar大鼠体液成分和脂肪分布的初步研究

摘要:目的　探讨应用生物阻抗分析仪测量不同性别Wistar大鼠体液成分和脂肪分布情况。 方法　利用生物阻抗分析仪检测Wistar大鼠身体组份,包括体液总量(TBW)、细胞内液(ICF)、细胞外液(ECF)、脂肪量(FM)、除脂肪量(FFM)、体液总量/ 体质量(TBW/BW)、细胞外液量/ 体质量(ECF/BW)、细胞内液量/ 体质量(ICF/ BW)、脂肪量/ 体质量(FM/BW)和除脂肪量/ 体质量(FFM/BW)。雄性组13只,雌性组,13只分别检测各项指标改变,以证明不同性别正常成年Wistar大鼠身体组份构成。 结果　不同性别两组间比较,雄性Wistar大鼠体液总量、细胞内外液含量、TBW/BW、ECF/BW、ICF/BW高于雌性Wistar大鼠,P值均小于0.05,差异有显著性。 FM/BW、FFM/BW比较,P值均小于0.05,两组差异有显著性。 雌性Wistar大鼠的脂肪含量高于雄性Wistar大鼠。 结论　正常雄性成年Wistar大鼠的体液含量高于雌性Wistar大鼠,而雌性Wistar大鼠脂肪百分比高于雄性。
