The paper introduces the operation principle and characteristics of the temperature sensor DS18B20 and the monochromatic graphic lattic module YEJHD12864A, and gives out the hardware and software design with the characteristics of simple interface, high precision, good antiinterference ability, and reliable operation.
Presents the application of database system of material information, thermodynamic method, quantum theory about molecular orbital, NN method and topology in material design with the development of computer technology and quantum theory as an important tendency in material design.
Orthogonal experiment of PTA powder surfacing was performed by orthogonal design ,with factors: element of Cr、 Mn、W and index: HRC hardness of Q235 steel surface by the orthogonal polynomial regression.
The experiment utilized the split-plot design with fertilizers as main plots and plant density as subplots,to study the characteristics of panicle and grain structure matched with a yield of more than 9t/ hm~2 for the new hybrid rice combination "Teyou 649".
An orthogonal quadratic regression rotation combinatorial design with 4 factors, i.e. nitrogen(N), phosphor(P), potassium(K), and boron(B), was adopted in field experiments. Fertilization models were built up and analysed for yield, oil content, oil yield and protein of yellow-seeded rape.
The research on urban disaster prevention is not only mainly about the architecture standard, but also aims at spatial distribution of city and architecture different function system, space planning and design with nature.
To compare the fluid type aerodynamic design with the overall structural optimization design, a study of the mine used fanner design is fulfilled in this paper. The authors put forward some new principles in design and set up a general optimization model, and in the meantime, they propose some approaches to raise the efficiency and to improve the performance.
