在Web测试过程中,某些步骤所涉及的页面操作比较多,测试人员需要根据页面DOM的结构和填充的数据重新构建测试代码的挑战。这样增加了测试人员的工作强度和代码编写的工作量。每一次的页面测试基本都可以归纳为查找页面元素和处理元素动作。将自动化测试组件进行二次封装,可以减少测试过程中的重复代码编写,让开发人员专注于测试过程的数据编制。介绍一种在Python环境下,以外部数据驱动WebDriver实现自动化测试的组件的设计与实现方法。该方法将页面操作的动作和填写的信息保存在外部数据文件中,将常用的执行动作和填写的数据组合为页面操作的过程封装为一个组件。利用此套组件,可以实现“数据-操作-代码”的分离,大大减少了测试人员的开发代码量。

The Ru complexes have garnered a great deal of attention for antitumor phototherapy; however, achieving efficient cellular uptake and tumor-specific activation represents a major challenge. Herein, we synthesize a hypoxia-activated Ru complex(RuANM) and construct it into supramolecular polymers(PolyRuANM) through high binding affinity interaction. The amphiphilic supramolecular polymers possess self-assembly, resulting in the formation of diverse nanostructures exhibiting a range of morphologies by simply adjusting the host-guest ratio. As the polymer nanostructure size and morphology have been optimized, PolyRuANM prevents premature drug leakage and accumulates rapidly in the tumor cells. In the tumor hypoxia microenvironment, the polymer undergoes selective activation and disintegration, leading to the unlock of Ru ***, the subsequent application of red light irradiation exacerbates the hypoxia and potentiates the liberation of the Ru complexes. This polymer design concept provides some novel insights into on-demand drug delivery and smart chemophotodynamic therapy.

时间来自何方?时间与物体移动有关,典型事例是太阳运动。这是汉语时间演化的基本事实和具身认知。基于此理念,我们提出事件空时同体说:事件由动体及空间和时间组成,它们同存共变,形成事件空间-时间同体线。由此假说可推导出两类事件-时间关联及其在汉语中的表现:事-时转喻关联(可为空-时词义衍生和时-事应景联通提供转喻理据)和事-时非转喻关联(可为语句和语篇中的事-时关联提供解释)。本研究在事件大视野中考察空间和时间,证明事件与时间的关联,也探明了时间转喻的基础性。

Gd_2O_3 :Eu^(3+) downconversion luminescent powder was prepared using the homogeneous precipitation method. Its optical properties were analyzed and it was introduced into a dye-sensitized solar cell (DSSC). As a luminescence medium, Gd_2O_3 :Eu^(3+) improved light harvesting via conversion luminescence and increased the photocurrent of the DSSC. As a p-type dopant insulating rare earth oxides form an energy barrier, and the Gd_2O_3 :Eu^(3+) elevated the energy level of the oxide film and increased the photovoltage. The photoelectric conversion efficiency for a DSSC with Gd_2O_3 :Eu^(3+) doping (6 : 100) reached 7.01%, which was 17.4% higher than the photoelectrical conversion efficiency of a DSSC without Gd 2 O 3 :Eu 3+ doping.

[Objective] This study aimed to construct RNAi expression vector against r/boflavin synthase （RS） gene. [Method] By using the primers designed based on RS gone coding sequence that was screened from Arabidopsis cDNA library, the 476 bp cDNA fragment of RS was amplified from pGADTT-RS recombinant plasmid, and then cloned into pUCm-T vector to obtain pUCm-RS. Two RS fragments （476 bp） were obtained through digesting pUCm-RS with restriction enzymes PstI/BamHI and PstI / Xhol, and then respectively connected into vector pBSSK-in to form pBSSK-RS-in-RS, in which the two RS fragments were inverted re- peats. Finally, the transform unit RS-intron-RS, got by digesting vector pBSSK-RS-in-RS with Sac I and Kpn I, was ligated into expression vector pCAMBIA1301 to obtain the RS gene silencing vector. [ Result] The restriction enzyme digestion sequencing analysis proved that the RS gene silencing vector was successfully con- structed. [ Conclusion] This study may provide a basic material for further studies on the bio-function of RS gene and the mechanism of signal transduction induced by HpaGxoo in plant.

以《培智学校义务教育课程标准(2016年版)》和部编版培智学校教材为代表的国家课程是当前培智学校开展课程与教学活动的重要依据。为了解新课标背景下四川省培智学校教师的课程实施的情况,本研究选取省内三所有代表性的培智学校部分教师进行焦点团体访谈。研究发现,培智学校教师对国家课程的认识具有两面性,国家课程的落实体现了从理念认知到教学实践的深化,教师的困难及需求凸显在从课标文本到课堂教学的转化中。通过进一步分析,培智学校课程实施存在以下问题:其一,落实新课标的理想与现实存在差距;其二,基于新教材的课程实施取向占主导;其三,教师专业知识与能力制约了国家课程的校本化实施。基于上述问题,提出了进一步修订完善培智学校课程标准;多元并举开展培智学校课程资源建设;培智学校需积极探索国家课程校本化实施路径;培智学校教师需主动提升课程实施能力等建议。
