In this article, theoretical analysis and different testing techniques were used to study the reaction pathways and synthesized products of phosphoric acid and aluminum hydroxide at different Al/P molar ratios. The results show that: (a) When the molar ratio of phosphoric acid/aluminum hydroxide is 1:3, the reaction will produce stoichiometric aluminum dihydrogen phosphate (Al(H 2 PO 4 ) 3 ); (b) when Al(OH) 3 is excessive, an intermediate, monohydroxy aluminum dihydrogen phospate (HO-Al-(H 2 PO 4 ) 2 ), will appear, which is unstable and will continue to react according to two reaction pathways, one is intramolecular dehydration to form phosphoric acid hydrogen-dihydrogen aluminum diphosphate (H 2 PO 4 )Al(HPO 4 ); the other is intermolecular dehydration cross-linking to form a polymeric macromolecular aluminum phosphate H-((HPO 4 )(H 2 PO 4 )Al-O-HPO 4 -Al(H 2 PO 4 )-O)n H. The ratio of the two pathways is affected by the excess of Al(OH) 3 . When the excess of Al(OH) 3 continues to increase, the ratio of the second reaction path begins to increase and the viscosity of the product gradually increases. Adhesion experiments show that the aluminum dihydrogen phosphate has the best bonding performance benefiting from its lower viscosity.

Self‐doped TiO2 nanotube array (DTNA) electrodes were fabricated through anodic oxidation combined with cathodic reduction. The morphology and structural features of pristine TiO2 nanotube arrays and DTNA electrodes were studied through scanning electron microscopy, X‐ray diffractometry, and X‐ray photoelectron spectroscopy. An accelerated life test was used to test the electrode service lifetime and thus the electrode's stability. The service lifetime of the DTNA electrode prepared at constant 40 V for 6 hr was approximately 338.7 hr at constant 1 mA/cm2 in a 1 M NaClO4 solution. Methyl orange (MO) was employed as the degradation probe for measuring electrochemical oxidation performance. The color removal rate of 200 mg/L MO of the DTNA electrode (85.2% at 1 mA/cm2) was greater than that of the Ti/IrO2 electrode (31.1% at 1 mA/cm2). The larger the surface area of the DTNA electrode is, the more conductive the electrode is for the degradation of organic substances. Organic degradation on the DTNA electrode occurred primarily through an indirect pathway (producing [∙OH]).

The application and popularization of internet of things technology fundamentally change management operation mode and service model of libraries in colleges and universities. Internet of things intelligent library system in colleges and universities is constructed on the basis of information items, independent network and intelligent application technology architecture. Traditional library and intelligent library based on Internet of Things are compared. Quality and efficiency of book management can be greatly increased in intelligent libraries of colleges and universities based on internet of things.

Abstract-We adopt the Self-esteem Scale (SES) and the Simplified Coping Style Questionnaire, to make a random investigation among the Binzhou Polytechnic students in 6 professionals of grade 2012. As a result, the Self-esteem Scale score was 32.59 ± 3.40. Positive coping style score was 2.14 ± 0.38, negative coping style score was 1.29 ± 0.48. And we distinguished the students' gender, they from the city or the countryside, and their family economic status, comparison the survey results. We analysed the correlation of self-esteem and coping styles, and organized the commonly used coping styles for high vocational students. The purpose of this study is to provide guidance for the mental health education of high vocational students.
