佛教从印度和中国传入越南之后,成为了越南的一个宗教,在形成和发展的过程中,不可避免地与传统文化碰撞融合,成为越南化的佛教。它与印度佛教有许多差异,深刻地影响了越南文化的各个方面,其中竹林禅派是具有代表性的。竹林禅派是在中国禅宗和越南禅宗之间孕育、形成、发展的禅派,与当时的越南文化和社会背景紧密结合。竹林禅派出现之前,越南已有了昆尼多流支、无言通和草堂这三个禅派,但它们都起源于中国,可以说是中国禅在越南的一个分支。陈仁宗想根据越南的实际情况,创立一个特别的禅派。他汇集上述三个禅派的特点,运用对禅的理解,并结合自身修行的经验,提出了一种新的禅学思想,最终成为竹林禅派。玄光三祖圆寂(1334年)之后,竹林禅派开始衰落,在佛教史上仅能看到一些隐修的僧士,没有严格意义上的宗教组织。直到1981年,越南佛教正式复兴,对这次复兴贡献最大的是清慈禅师,他认为越南佛教的最关键一脉是竹林禅,所以想重振越南佛教,必须复兴竹林禅派。论文从汉喃作品《禅宗本行》入手,同时参考和借鉴了陈朝的其他一些文献资料和相关研究成果,对竹林禅派的历史形成过程和具有自身显著特色的思想这两个方面进行研究。论文的第一章描述《禅宗本行》作品的形成背景和流传的问题,第二章是介绍陈朝早期各位国王的学道和行道过程并介绍竹林禅派禅学的特点,第三章是对该书学术价值进行的分析。喃文文学是越南文学宝库中不可缺少的部分。笔者选择汉喃文献作品来研究,是因为它不仅让我们清晰地看到竹林禅派的起源和面貌,还体现了民族自豪意识。陈朝各作者已正式把喃字运用到文学论坛中,由此我们同样可以看到喃字发展与越南佛教发展过程之间的密切关系。

Four activated carbon(AC) samples prepared from rice husk under different activation temperatures have been characterized by N2adsorption–desorption isotherms, thermogravimetric analysis(TGA–DTA), Fourier transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM). The specific surface area of AC sample reached 2681 m2 g 1under activation temperature of 800 1C. The AC samples were then tested as electrode material; the specific capacitance of the as-prepared activated carbon electrode was found to be 172.3 F g 1using cyclic voltammetry at a scan rate of 5 mV s 1and 198.4 F g 1at current density 1000 mA g 1in the charge/discharge mode.& 2014 Chinese Materials Research Society.

For human-machine communication to be as effective as human-tohuman communication, research on speech emotion recognition is *** the models and the classifiers used to recognize emotions, neural networks appear to be promising due to the network’s ability to learn and the diversity in configuration. Following the convolutional neural network, a capsuleneural network (CapsNet) with inputs and outputs that are not scalar quantitiesbut vectors allows the network to determine the part-whole relationships thatare specific 6 for an object. this paper performs speech emotion recognition basedon CapsNet. The corpora for speech emotion recognition have been augmented byadding white noise and changing voices. The feature parameters of the recognition system input are mel spectrum images along with the characteristics of thesound source, vocal tract and prosody. For the German emotional corpus EMODB, the average accuracy score for 4 emotions, neutral, boredom, anger and happiness, is 99.69%. For Vietnamese emotional corpus BKEmo, this score is94.23% for 4 emotions, neutral, sadness, anger and happiness. The accuracy scoreis highest when combining all the above feature parameters, and this scoreincreases significantly when combining mel spectrum images with the featuresdirectly related to the fundamental frequency.
