The development of precast concrete structure is an effective way to promote industrialization of construction industry and housing industrialization, and is also a inevitable choice for green development. Grouted splice sleeve connector, regarded as one of the key technologies of precast concrete structure, has the advantages of high strength and good seismic performance. In this paper, the development of grouted splice sleeve connector is systematically summarized both home and abroad, existing problems in the domestic research of sleeve are evaluated and analyzed, and corresponding countermeasures are also further proposed.

Normal Green

With China’s economic development entering a new normal, green finance has become a new direction to explore the sustainable development of economy in the supply side structural reform task of “three removal, one reduction and one compensation”. Firstly, this paper analyzes the concept of green finance and its development status. Secondly, taking green credit as an example, this paper makes an empirical study on the contribution of green finance to sustainable economic development. Finally, according to the results of empirical research, some suggestions including increasing the application proportion of green finance, improving green financial products and business model and forming a market mechanism for green finance to promote green development independently, are put forward to improve the sustainable development of green finance in China.

Physical And Chemical

Rare-earth phosphates are of particular interest because of their catalytic properties associated with the hydrolysis of many aromatic chlorides in the petroleum industry. Lanthanum phosphates (LaPO4) which have been doped with small amounts of copper have shown increased catalytic activity (1). However the physical and chemical characteristics of the samples leading to good catalytic activity are not known.Many catalysts are amorphous and thus do not easily lend themselves to methods of investigation which would include electron microscopy. However, the LaPO4, crystals are quite suitable samples for high resolution techniques.The samples used were obtained from William L. Kehl of Gulf Research and Development Company. The electron microscopy was carried out on a JEOL JEM-100B which had been modified for high resolution microscopy (2). Standard high resolution techniques were employed. Three different sample types were observed: 669A-1-5-7 (poor catalyst), H-L-2 (good catalyst) and 27-011 (good catalyst).

Development Status

Die vergangenen Jahre haben der bundesdeutschen Pflege einen unerwarteten und überaus großen Entwicklungssprung beschert: binnen Kürze entstand eine Vielzahl von Pflegestudiengängen. Zusätzlich hielt Pflegewissenschaft Einkehr in die Hochschulen und begann der Aufbau von Pflegeforschung, womit wichtige Voraussetzungen dafür geschaffen sind, Pflege als wissenschaftliche Disziplin zu entwickeln. In dem vorliegenden Beitrag wird eine erste Bilanzierung vorgenommen und der erreichte Entwicklungsstand im Bereich der Pflegepraxis, der Pflegestudiengänge, der Wissenschaftsentwicklung und Pflegeforschung betrachtet. Dabei wird gezeigt, daß – trotz der Vielzahl in den letzten Jahren erreichter Erfolge – eine ganze Reihe weiterer Aufgaben der Bearbeitung harren. Dazu gehört, das nach wie vor vorhandene Vakuum auf der Ebene der Wissenschaftsentwicklung zu füllen, den Ausbau von Pflegeforschung voranzutreiben und geeignete Bedingungen für die Förderung von wissenschaftlichem Nachwuchs zu schaffen.
