Overseas and Domestic Research Status There are multiple ways of measuring torque, for example, torque is measured by feelings of shaft deformation, such as the way of pasting strain gauges in the rotating shaft surface, coating magnetostrictive materials, placing piezoelectric crystal and so on; The torque is also can be acquires by measuring the phase of shaft two section with double section tooth ring, photosensitive materials, laser speckle optical methods.
Various types of torque sensors are designed, such as magnetic susceptibility, gas sensor, force sensor, thermal, optical, laser and other types, the torque sensor materials are from metal materials into semiconductor, ceramic, optical fiber and other.

In the meantime, the food technology and food industry have also maintained a rapid growth with many new technologies, new materials and new products emerging in endlessly.
However, with the media exposure of the pollution of raw-food materials, abuse of food additives, and substandard food packaging, food safety has drawn more and more attention from various circles of the society.
Focusing on the topics of new materials of food packaging, food packaging safety and traceability, food packaging decoration, food packaging designing and engineering, "2013 China Academic Conference on Food Packaging" invited Professor Luciano Piergiovanni from the Department of Food, Environmental and Nutritional Sciences of University of Milan, Associate Professor Ngamtip Poovarodom from the Department of Packaging and Materials Technology of Kasetsart University, Professor MA Yongjun from School of Computer Science and Information Engineering of Tianjin University of Science and Technology to make keynote speeches respectively, namely "Research on Application of Nano Bio-based Materials in Functional Packaging", "Safety and Regulations: The Challenges for Food Packaging", and "Technology of Internet of Things and Its Application in Food Safety".
The conference received more than 180 papers, including 3 keynote speeches and 100 excellent papers which were all published in Applied Mechanics and Materials.

Two reviews, one describing the American Society for Testing and Materials(ASTM) standards for fire debris analysis and the other listing recent advances in a variety of areas related to fire debris analysis, have also been published in 2006 and 2007[3].
And maybe more factors will be taken into consideration such as time, space, the degree of burning, the fire extinguishing materials, temperature etc.
