The tensile strength of a 2D woven C/SiC composite laminates notched with central hole was analyzed and calculated by finite element method. By considering the nonuniformity, material of open-hole specimen was divided into several parts with different density. Tensile properties of 2D woven C/SiC composites...

At present, the creative industry has achieved rapid development, and the design planning of creative products is pivotal to ensure the sustainable development of this industry. A variety of key theories have been produced in the development of creative products, and to analyze these key theories and...

Aiming at the fault phenomenon of “the temperature of food cold storage does not meet the standard” in the fault of ship refrigeration system, based on the analysis of its possible fault factors, a fault tree model is established, which can improve the speed of finding and troubleshooting; At the same...

As people pay more and more attention to the shaping of healthy body, the current gym, a commercial sports place, has developed rapidly and become a new leisure space in modern society. The themes of geographical imagination, local identity and spatial production in fitness and leisure space began to...

The wind tunnel test control is the key to the wind tunnel tests. This article Studied 0.75m × 0.75m With backflow wind tunnel measurement and control technology, through the transformation of the wind tunnel motor to improve the stability and uniformity of the airflow and reduce turbulence degree; through...

The automation and intelligence of the overhaul technology are related to the level of the whole substation automation and intelligence. Aiming at the problems of low automation level of substation high-voltage equipment overhaul, this paper mainly studies robot-based live overhaul technology. The design...

According to original environment destroy of the precious endangered plants, the information system need be built to monitor the endangered plants. Here, using C++, combined with Arcobject soft to establish the management platform system. The main design is data bank design and user interface design....

Osteopontin (OPN), as a malignant transformation related protein phosphorylation was firstly completed the extraction by Senger in 1979. With the progress of research on osteopontin (OPN), people found out that there was little amount in the normal tissues that was showed with low expression, however,...

Osteopontin (OPN) is a kind of phosphorylated acidic glycoprotein, human beings' osteoclasts, macrophages, T cells, and vascular smooth muscle cells can secrete OPN, the gene is located on chromosome 4q13. OPN has a function of adhesion to protein, which can be combined with CD44, integrin v 3 and v...

NGF and its receptor are expressed in multiple nervous system and tumor of the non-nervous system, which also participate in tumor proliferation, differentiation, apoptosis, angiogenesis and other biological behaviors. In this paper, it takes the interpretation of nerve growth factor (NGF) as the breakthrough...

A hybrid BPNN-weighted GREY-C3LSP prediction (BWGC) is used for resolving the overshooting phenomenon significantly; however, it may lose the localization once volatility clustering occurs. Thus, we propose a compensation to deal with the time-varying variance in the residual errors, that is, incorporating...
