In the second part, by using uniform design and orthogonal design methods, some groups of mix test of foam lightweight with different component are conducted, the test data is analyzed by neural networks model and regression model, and optimum mix proportion is obtained. Orthogonal design for mix material considering density factor is presented, as well as uniform design for mix material adapting to different density. The mechanic characteristics of foam lightweight material and engineering characteristics differing from general material under an allround press are founded. Through the analysis of asymmetry settlement for Doulong sluice and the comparison of correct deflection scheme, the foam lightweight material shows some advantages in the load reduction.

Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure. CT showed that the rhinoscleroma in granulomatous stage was a soft mass which was irregular in shape, with a well-defined margin, inhomogeneous density and bone destruction. MRI showed heterogeneous hyperintensity on T1WI and isointensity on T2WI with an intermediate heterogeneous enhancement.

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

Results In 11 cases,5 cases were intracranial,and 6 cases intravertebral canal.MRI could effectively show similarly shuttle or long-round shape's abnormal signal imaging.The T1W imaging showed uniformity or asymmetric and low or equal signal.The borders were slighty low or equal signal intensity,some had spetum.The T2W imaging showed obviously high signal,and a few cases showed slightly high or equal signal,while the borders showed slightly low or equal signal imaging.The thin peripheral could be obviously enhanced,but without inner enhancement.

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

模拟结果表明，热变形过程中，试样的各个部位的变形分布不均匀，心部的等效应变最大，变形的不均匀性随应变速率的增大而增大，但是变化的程度不大；试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；动态再结晶晶粒尺寸标准偏差随应变速率的增加而减小。
