The present invention relates to a halogen-free, multilayered, uniaxially oriented heat shrink film comprising a core layer comprising a blend of polyolefins; a first skin layer on the upper surface of the core layer, and a second skin layer on the lower surface of the core layer, wherein the first and second skin layers independently comprise a polyolefin blend and wherein the shrinkage of the film is at least about 40% in the machine direction at 270 DEG F.

本发明涉及一种不含卤素、多层、单轴取向的热收缩薄膜，包含含聚烯烃共混物的芯层；在芯层上表面上的第一皮层，和在芯层下表面上的第二皮层，其中，第一和第二皮层独立地包含聚烯烃共混物，并且其中，在270°F，在纵向薄膜的收缩率至少约为40％。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.

拱坝的地基一般是层状岩石地基，有的层厚度很小，这样就有多个岩层和坝体某层单元接触，本文根据岩基与坝体接触的几何关系，利用形函数的性质，提出24节点六面体层单元，这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的，其形函数采用可以拆分的形式表达，因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况，可以模拟一、二、三、四个棱边与错动带接触的情况，还可以退化为12节点的四边形面单元，以及五面体层单元。

It takes several steps to make it: firstly soak soybeans in well water; secondly grind it to make soya bean milk; thirdly filter it with a piece of gauze; fourthly boil the soya bean milk in a pot until it becomes thick; fifthly lay a piece of fine gauze in a container; sixthly ladle the soya bean milk over the gauze; seventhly lay another piece and repeat again many times until the container is full; then press them to get rid of water.

用上好井水浸泡黄豆，再用石磨推成浆，再用纱布过浆去渣，舀浆入锅内烧开至稠。在一容器内铺一层细纱布，将烧稠的豆浆舀在纱布上，然后再在上面铺一层细纱布，再舀豆浆，装满后在上面加木板上榨，去掉水分，揭去纱布即可获得薄如纸、白如雪的千张。

Wall which has the guard shield, to swarm upward to attack; they are looked like the fly to dance in the air in the broke big space between two floors with uncountable death ray dodged; the first army corps whose population is not many can not but upward retreat.

At 800 and 900℃, Ti-45al-10Cr alloy formed a similar layered scale with Tial, consisting of an outer layer of TiO2, an intermediate al2O3 barrier and an inner layer of a mixture of al2O3 and TiO2, exhibited larger weight gains than Ti-50al due to the dopping effect of Cr.

结果表明，Ti－45Al－10Cr合金在800和900℃形成的氧化膜具有与TiAl合金同样的分层结构，外层为Ti02，内层为Ti02和al2O3的混合氧化物，在内外氧化层中间有一富Al2O3的中间层，但内氧化层中有大量Cr掺杂、其氧化增重比Ti-50al的大。

The invention also relates to a device comprising at least one one-way detection unit constituted by a pressure sensor disposed outside the cladding and connected to the inside the cladding via a horn-shaped duct which slopes relative to the axis of the cladding, which has its mouth opening out in the cladding, and which has its tip connected to the pressure sensor.
