Research on the cultural transmission of college students under the background of the ＂double first-class＂university construction

Throughout the world＇s first-class universities, the university culture is the soul of the universities＇ survival and development, and the cultural competitiveness has become an important symbol of the core competitiveness of the universities. The first-class university culture is very important to the construction of the ＂double first-class＂. Therefore, our country should bring the university cultural construction into the big pattern of the ＂double first-class＂ construction, guide the construction of the university cultures with the socialist core values, strengthen the cultural confidence, inherit the Chinese excellent traditional cultures, pay attention to the rational exchange of the multicultural cultures, highlight the Chinese characteristics of the first-class university cultures, and realize the dream of the Chinese nation of a power of the higher education.

Goals and Key Technology of Fertilizer-pesticide "Double Reduction" and Synergism for Greenhouse Strawberry

In order to develop green good, reduce the use of chemical fertilizer and pesticide, realize ＂double reduction＂ and synergism, improve safety and quality of products, protect the ecological environment and promote the healthy and steady development of strawberry industry, the goals and key technology of fertilizer-pesticide ＂double reduction＂ and synergism for greenhouse strawberry are summed up in this paper targeting at the current situation of strawberry production and combined with the new technology achievements at home and abroad. The key technology includes six items： healthy seedling cultivating technique, soil improvement and continuous cropping obstacle treatment technique, agricultural ecological prevention tech- nique, physicochemical trap of pest control technique, biological control technique and low residual risk chemical control technique.

An Incursion of Off-Equatorial Subsurface Cold Water and Its Role in Triggering the “Double Dip” La Nia Event of 2011

Based on Global Ocean Data Assimilation System （GODAS） and NCEP reanalysis data, atmospheric and oceanic pro- cesses possibly responsible for the onset of the 2011/12 La Nifia event, which followed the 2010/11 La Nifia even--referred to as a ＂double dip＂ La Nifia--are investigated. The key mechanisms involved in activating the 2011/12 La Nifia are illus- trated by these datasets. Results show that neutral conditions were already evident in the equatorial eastern Pacific during the decaying phase of the 2010/11 La Nifia. However, isothermal analyses show obviously cold water still persisting at the surface and at subsurface depths in off-equatorial regions throughout early 2011, being most pronounced in the tropical South Pacific. The negative SST anomalies in the tropical South Pacific acted to strengthen a southern wind across the equator. The subsurface cold water in the tropical South Pacific then spread northward and broke into the equatorial region at the thermo- cline depth. This incursion process of off-equatorial subsurface cold water successfully interrupted the eastern propagation of warm water along the equator, which had previously accumulated at subsurface depths in the warm pool during the 2010/11 La Nifia event. Furthermore, the incursion process strengthened as a result of the off-equatorial effects, mostly in the tropical South Pacific. The negative SST anomalies then reappeared in the central basin in summer 2011, and acted to trigger local coupled air-sea interactions to produce atmospheric-oceanic anomalies that developed and evolved with the second cooling in the fall of 2011.

引发内蒙古汛期暴雨洪涝灾害的降水事件雨强特征分析

选取2017—2018年汛期(6—8月)内蒙古108例引发暴雨洪涝灾害的降水事件,对其雨强持续性、最大值、日变化等特征进行分析,通过双重e指数函数和百分位相结合方法,确定降水事件阈值。结果表明:(1)降水事件高发区在大兴安岭东部,最高可达5~6次,持续时间最长为10d,降水事件次高发区在阴山山脉以南;(2)降水事件雨强最大值和最小值均出现在东部地区,极差最大值达70.4mm·h^(-1),西部和中部地区雨强最大值较接近,中部地区雨强极差最小,为16.0mm·h^(-1),但降水事件平均雨强最大值出现在西部地区,最小值出现在中部地区;(3)降水事件雨强日变化特征具有地域性差异,西部地区雨强(平均雨强)最大值出现时间具有分散不集中且差异较大的特点,易出现在凌晨、早晨、中午和傍晚,中部和东部地区易出现在中午和下午;(4)西部、中部和东部地区降水事件阈值分别为13.8mm·h^(-1)、10.0mm·h^(-1)和14.2mm·h^(-1)。

“Double Surplus,” Capability Gaps and Innovation: A Macro- and a Micro-perspective on the Transformation of the Chinese Mode of Economic Development

In order to deploy the crucial levers in the transformation of the Chinese mode of economic development, it is necessary to identify the nature and reasons for the economy＇s existing mode of operation. The paradox of China＇s ＂double surplus＂ in the international balance of payments reflects the substantive issue of the appearance of a capability gap in Chinese economic development, which, interacting with dependence on FDI, hinders industry upgrading. As a result, the extensive mode of development has persisted and even worsened, rendering the Chinese economy more vulnerable to external shocks. At the historic juncture when the international economic environment is undergoing dramatic changes, the Chinese economy is likely to suffer severe setbacks due to its capability gap and dependence on FDI unless there is substantial development in its technological and organizational capacities and institution-building. Therefore, the critical variable in transforming the Chinese mode of economic development is capability growth.

双切口套法预防开放性胃肠手术后切口感染的临床效果观察

目的探讨双切口套法预防开放性胃肠手术后切口感染的临床效果。方法选取2013年3月-2014年8月在本院实施开放性胃肠手术的75例患者作为研究对象,随机分为观察组（38例）和对照组（37例）。观察组在开放性胃肠手术中采用双切口套法,对照组术中不使用任何切口保护套。比较两组的手术时间、术后首次排气时间、首次排便时间、住院时间及切口感染率。结果两组的手术时间比较,差异无统计学意义（P〉0.05）。观察组的术后首次排气时间、首次排便时间及住院时间显著短于对照组,差异有统计学意义（P〈0.05）。观察组的切口感染率为2.63%,显著低于对照组的16.22%,差异有统计学意义（P〈0.05）。结论双切口套法可以明显降低开放性胃肠手术后的切口感染率,提高临床疗效。
