摘要：The Awakening was Kate Chopin＇s masterpiece, describing a wealthy businessman＇s wife--Edna＇s confusion, awakening, pursuit, and suffocation of self-awareness in the South of America in the late 19th century. With the method of close reading in new criticism, this paper reinterprets Edna＇s awakening process. Her awakening process is accompanied by the symbolic image of ＂bird＂, representing women＇s situation in the patriarchal society and carrying Edna＇s hope for freedom, love, and self-realization. The application of bird＇s symbolic image reflects Kate Chopin＇s compassion for women in the patriarchal society, making the novel more appealing with its profound humanitarian connotations.

摘要：The American writer Kate Chopin＇s masterpiece, The Awakening published in the late 19th century is one of the classics in female literature. The heroine Edna having the courage to pursue self-reliance and express her self-awareness, is regarded as a ＂new woman＂, while the comments on her husband, Mr. Pontellier are quite negative--He regards Edna as a private property and a sexual tool, leading to her awakening and suicide. In this paper, the author reinterprets Mr. Pontellier with the method of close reading in new criticism, deeming that it is the binary opposition in thinking that leads to the misreading. Mr. Pontellier was just a follower of the tradition and custom. The objective evaluation and reinterpretation to him can help students to develop the habit of critical thinking and the courage to pursue truth is case they form a simple thinking mode of the binary opposition.

摘要：In order to filter signal effectively according to selective center frequency, a voltage-controlled dynamic band-pass filter with gain compensation was designed based on voltage-controlled gain wideband amplifier VCA810. The transfer function of the filter was analyzed and gain compensation voltages were given through tests; besides, a system was designed, including the gain compensation circuit and the control voltage circuit, etc. Center frequency will change from 1 kHz to 20 kHz according to control voltage on condition that bandwidth of the filter remains constant. The designed system has the advantages of simple structure, low noise, stable performance and convenient adjustment.

摘要：对不添加镇流电阻的非均匀发射极条间距的多发射极条异质结双极晶体管(HBT)的射频功率性能和表面温度分布进行了测量,并与常规采用镇流电阻的多发射极条功率HBT进行了比较。实验结果表明,对具有非均匀发射极条间距的多发射极条HBT,采用US QFI TMS红外测量系统测得的最高表面温度、温度分布均匀性以及采用射频测量系统测得的射频功率增益和功率附加效率,分别低于、好于和高于具有镇流电阻的多发射极条功率HBT的情况。这些结果的取得,得益于采用非均匀发射极条间距改善了多发射极条HBT的热电正反馈和不同发射极条之间的热耦合,以及摆脱了传统HBT加镇流电阻带来的对射频功率性能的负作用。

摘要：设计了一种电极间隔为10cm的介质阻挡放电装置,以氩气为工作气体,在低气压下产生等离子体。采用发射光谱法,研究了放电空腔内等离子体电子温度和电子密度随空间位置的变化规律。等离子体电子温度的变化通过使用Corona模型计算获得,等离子体电子密度的变化通过分析Ar原子750.4nm谱线强度变化得到。实验发现空腔内不同位置的等离子体电子温度和电子密度是不同的。当测量位置从阴极向阳极移动时,电子温度先略上升而后迅速下降,再缓慢上升;电子密度先缓慢而后迅速地增大。
