母语思维在英语学习过程中会产生正面的和负面的影响．即负迁移和正迁移；我们的母语在诸多方面不同于英语，汉语是注重主题的语言。而英语则是注重主语的语言．如果一味地用汉语句式来套用英语句子。我们就会错误百出。但是我们可以利用语言的共性来促进“正迁移”．借助母语思维来促进英语学习，从而提高外语学习效率。我们要避免负迁移。促进正迁移；充分利用汉语思维，进行汉英对比分析．区别不同点。联系相同点，从而达到尽快掌握英语之目的。

Clonal plants in Mu Us sandland change the sandy enviroment. The clonal plant is a kind of resource in restoration of the Mu Us sandy landscape. Soil samples at depth of 50 cm in the rhizosphere of the clonal plants were collected in 4 replicates at each location and divided into sections corresponding to 0—10, 10—20, 20—30, 30—40 and 40—50 cm depths in two representative sites from north to south in Mu Us sandland, northwestern China, in July 2005. Clonal plants included Psammochloa villosa and Hedysarum laeve. The colonization and ecological distribution of arbuscular mycorrhizal (AM) fungi were investigated in the rhizosphere of clonal plants in Mu Us sandland. The results showed that the clonal plants established well symbiosis with AM fungi; AM fungal species and spatial distribution were significantly related with the host plants and soil factors. Of 16 AM fungal taxa in three genera isolated and identified, Glomus multicaule was only observed in the rhizosphere of Psammochloa villosa; Glomus aggregatum, Glomus hydembadensis, Glomus constrictum and Acaulospora rehmii only appeared in the rhizosphere of Hedysarum leave. The depth of soil layers observably affected the spore density and the frequency of colonization (%F). The maximal %F and spore density occurred in the 10—20 cm layer at the site of Ordos Sandy Land Ecological Station, but which occurred in the 0—10 cm layer in Shanxi Yulin Rare Sandy-plants Conversation Field. AM fungal status and colonization might be used to monitor desertification and soil degradation.

Catiline, Ibsen’s first play, has often been undervalued. Ibsen’s comments on this play that the ideas he expressed in this juvenile attempt are still what he thinks of after he has made great achievements in dramatic creation exactly show its true value. To a large extent, it is Catiline’s persistent pursuit of his ideal that may have moved the dramatist who has throughout his own life pursued his own ideal. What’s more, Ibsen may also have noticed the similar ethical dilemma that faces him and Catiline: the contraction between his earthly duties and his pursuit of the ideal.

A new kind of matrix-valued rational interpolants is recursively established by means of generalized Samelson inverse for matrices, with scalar numerator and matrix-valued denominator. In this respect, it is essentially different from that of the previous works [7, 9], where the matrix-valued rational interpolants is in Thiele-type continued fraction form with matrix-valued numerator and scalar denominator. For both univariate and bivariate cases, sufficient conditions for existence, characterisation and uniqueness in some sense are proved respectively, and an error formula for the univariate interpolating function is also given. The results obtained in this paper are illustrated with some numerical examples.

Atmospheric pressure glow barrier discharge (APGBD) can operate at high pressure, and so vacuum device is not necessary. Furthermore, the produced plasma by APGBD has moderate electron temperature and density besides good uniformity. Therefore, APGBD has extensive potential applications in industry and has been becoming a hot issue in the research of low temperature plasma. In this paper, the main problems in the study of atmospheric pressure glow discharge generated by dielectric barrier discharge, including the experimental setup, judging criterion, discharging conditions, physical mechanisms, and parameter diagnoses, are discussed, and further research prospects of APGBD are proposed.

关键词： atmospheric pressure glow discharge dielectric barrier discharge low temperature plasma.

针对在低照度和弱纹理复杂的隧道环境中，采用三维激光扫描技术采集点云数据，点云语义分割精度难以保障的问题，提出一种基于点云动态图卷积网络改进的隧道点云语义分割网络(TDGCNN)。该网络采用多尺度策略改进边缘卷积层，扩展邻域范围，以增强对边缘特征的获取能力；同时，引入两种注意力机制，对特征进行聚合和学习，去除冗余特征。实验结果表明，TDGCNN在隧道点云数据集上的总体精度(OA)达到98.78%,平均交并比(mIoU)为84.95%,表现优于DGCNN、PointNet、PointNet++及GeoSegNet。在WHU-TLS数据集上的验证了TDGCNN对不同隧道场景的鲁棒性，通过消融实验则证实了网络中加入的两种策略的有效性，表明了TDGCNN能有效利用不同层次的特征，提升隧道点云语义分割精度。
