At the same time, the cooperation of the multi-layer frame structure is researched with FEA when the pre-stressed threads are stretching, and the relationship between the beam of stretching layer and the beams of nearly layers is discussed. The layout effect of regular reinforcement in the beam on the pre-stressed effective quantities is also analyzed, and the elementary estimation formula of pre-stressing loss on the multi-layer frame is also deduced according to the pre-stressing loss of one-layer pre-stressed frame structure.

The paper carries out mechanical analysis of the weight distributing of goods in loading container based on analysis of packing and tansporting environment, and draws the formula of the ratio of the weight of loading goods and the maximum loading weight W/W0, and the length distributing ratio of loading goods α=l/L under the condition that the bending quadrature produced by part load is within the range of the maximum bending quadrature. It also gives the graph that the sum deflection of mudsill and underside girder can reach high-point value with the length of bottom distributing varying, when the loading amounts of container of 20ft and 40ft are given. Furthermore, it provides the relation graph of an eccentric rate of loading goods and the allowed loading amount. For on-site safety loading work, it has certain guidance and reference value.

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.
