我国银行系P2P模式发展存在的问题及对策

随着我国互联网金融的火爆,P2P平台的快速发展,我国传统银行业受到一定的冲击。我国九家商业银行也相应推出自有的P2P平台,称为银行系P2P。银行系P2P一推出便受到广大投资者的追捧。但其收益率较低,管理模式滞后,风险控制体系不健全也是银行系P2P急需提升的短板。逐步提升产品收益、创新经营管理模式、健全风险控制体系是我国银行系P2P的当务之急。     

Creating pretence and sharing friendship: modal expressions in children's play

Friendships and play provide children with opportunities for mutual engagement, which both require and facilitate children's language use. Modality is a semantic system in the language associated with children's learning. One way in which modality is realised is through linguistic expressions which allow speakers to moderate the degree of certainty about the truth of propositions (expressions of possibility) and the degree of necessity with respect to proposals (expressions of obligation). No research has explored the relationship between friendship and children's use of modality. This paper reports on the use of both types of modal expression during play between five- and six-year-old children in two friendship contexts. Results showed that possibility expressions occurred at similar rates in both contexts while obligation expressions occurred significantly more often in play in high-level friendships than in low-level friendships. Findings suggest that in high-level friendships modality was used cohesively to create and extend pretend play, whereas in low-level friendships it was used to regulate behaviour. Because modal expressions are important resources for managing interpersonal relationships, for talking about ideas and situations beyond the here and now and for writing for a non-present audience, our findings provide valuable insights for educators of young children.

英语情态动词的语义特征分析及其对教学的启示

英语情态动词语义交错、用法多变。明晰情态动词的语义特征可以加深对情态动词语义的理解和提高语用能力。英语情态动词有功能性、主观性、即时性、多义性四大语义特征,上述四个特征对英语教师可以有以下四个方面的启示,即了解情态动词的功能性有助于拓展情态意义的表达方式,了解情态动词的主观性有助于对含有情态动词话语和不含情态动词话语差异的理解,了解情态动词的即时性有助于对情态动词中语气婉转或不确定性语义的把握,了解情态动词的多义性有助于对特定语境中情态动词的解读。

Three-step damage identification method based on dynamic characteristics

A three-step damage identification method based on dynamic characteristics is proposed to improve the structure reliability and security and avoid serious accident. In the proposed method, the frequency and difference of modal curvature （DMC） are used as damage indexes. Firstly, the detection of the occurrence of damage is addressed by the frequency or the square of frequency change. Then the damage location inside the structure is measured by the DMC. Finally, with the stiffness reduction rate as a damage factor, the amount of damage is estimated by the optimization algorithm. The three-step damage identification method has been validated by conducting the simulation on a cantilever beam and the shaking table test on a submerged bridge. The results show that the method proposed in this paper can effectively solve the damage identification problem in theory and engineering practice.     

塔式起重机的动力特性及地震响应分析

为了分析塔式起重机的动力特性及在不同水平下的地震响应,首先借助ANSYS有限元分析软件,对塔式起重机进行模态分析;其次对塔式起重机的有限元模型分别输入EI Centro、Taft及汶川什邡八角站三种激励地震波,分析塔身和水平横梁节点地震响应,最后讨论塔式起重机的抗震设计要点及隔震措施。结果表明：塔式起重机的塔臂疲劳主要由地震反应谱中的窄带过程控制,反之,塔臂的折断破坏是由宽带过程起主要作用。
