The new ideas from this paper: using mechanics principle study of soil, create a practical test to prove that it could change the physical mechanics character of base soil completely, reducing distortion, improving strength, and eliminating wet or sinking of base soil by seal extrusion during hole formation process at certain replacement rate; it could strengthen the loessial soil base to high bearing capacity to standard value of 300 to 400kPa through seal extrusion to hole formation technology together with rammed cement soil pile. Some value of the parameters adopted by bearing capacity calculation of the composite base of rammed cement soil pile with seal extrusion to hole formation exceeded the criteria of 'Technical Regulation on Building Ground Treatment'.(JGJ79-2002) This technology meet the design requirements and save investment.
本课题的创新点:1 利用土力学原理进行研究及理论推导,并经实践:证明了在置换率为某一定值的情况下,在成孔过程中通过挤密作用可以从根本上改变地基土的物理力学性质,使地基土的变形减小,强度提高,湿陷性消除;2 挤密成孔工艺与夯实水泥土桩的组合,可使低强度的湿陷性黄土地基变成高强度的复合地基,其承载力特征值可达 300~400kPa;3 挤密成孔法夯实水泥土桩复合地基承载力计算所采用的有关参数取值范围超出了《建筑地基处理技术规范》JGJ79-2002 中的有关规定;4 在节省投资的前提下,解决了地基高承载力、低变形及黄土湿陷性问题,达到了设计要求。

Polymer processing is a high-energy process operation, and screw machinery is widespread applied to the polymer processing, such as screw extruders, screw injection molding machine and so on. The screw plasticating and conveying equipments based on shear rheology are generally adopted in polymer processing, in which materiels are dominated by shear stress. Therefore, there are some ubiquity disadvantages of the current methods of polymer materials processing, such as long thermo-mechanical, high energy consumption, too big equipment structure, and dependence on material properties.
加热管高分子材料成型加工是高能耗过程作业,目前普遍采用螺杆机械,如螺杆挤出机、螺杆注射机等,在螺杆机械中物料塑化输运主要是靠螺杆旋转时对物料的拖曳作用,固体输送为摩擦拖曳,熔体输送为粘性拖曳,物料的速度梯度与其流动和变形方向垂直,这种流动与变形受剪切应力支配,所以当前的高分子材料加工方法普遍存在物料塑化输运所经历的热机械历程长、能耗高、设备结构大、对物料特性依赖性强等缺陷。

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓<1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓<0.5Ma, T〓A<850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.
