The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

Our results showed that the most appropriate rib's level for applying force was below the apex of scoliotic spine. From this appropriate level, the stress delivered to its conjunctive vertebra was the highest, as 1.3~1.8 times compared with others. Furthermore, the correction of Cobb's angle was also the highest, achieved 15%. The ML force was dominant in alteration of Cobb's angle, whereas the AP force was dominant in alteration of axial vertebral rotation. In addition, initial vertebral rotation influenced neither correction nor stress.

There was a significant inverse correlation between sarcomere length and A/I (r=-0.686, P.05). 4 Relations of the skeletal muscle histological characteristics and meat quality The muscle fibre and the myofibrils diameter were thinner, the muscle fiber density was denser, the sarcomere length was longer and the meat color was redder. The A/I was bigger, the meat color was whiter, contrarily was redder. The right amount of fat content may improve the meat brightness. The muscle fiber diameter and the myofibrils diameter were the biggest factors to influence the skeletal muscle shearing force, their assumed the obvious linear correlation. The muscle fiber density influence on the shearing force was only inferior to the muscle fiber and myofibrils diameter. Mensurate the IFA from tectology angle may reflect in intramuscular fat content. However intramuscular fat was not enough to carry weight on the shearing force, it may mostly affected on the smack, but not the tenderness expression.

猪骨骼肌组织学特性与肉质性状的关系肌纤维和肌原纤维直径越小、肌纤维密度越大、肌节长度越长，肉色鲜红；肌节中暗带比例越大，肉色偏白，而明带比例大，肉色偏红；适量的脂肪含量可以改善肉的亮度；肌纤维直径和肌原纤维直径对骨骼肌剪切力的贡献率最大，呈明显的线性相关，肌纤维密度对剪切力的贡献率仅次与肌纤维和肌原纤维直径；从组织形态学角度测定肌内脂肪面积比一定程度上可以反映肌肉内的脂肪含量，而肌内脂肪对肌肉剪切力的贡献率比较微弱，对肉食用品质的影响可能更多表现在改善肉的风味，而不是嫩度的表达。

On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.
