使不稳定

We also found that the content of Na(superscript +), K(superscript +) and proline in leaves varied with different treated days. Under all treatments, the absorption of Na(superscript +) increased and the content of proline in leaves decreased with the prolonging of treated days. The absorption of K(superscript +) measured on the 7th day and the 21st day increased and was restrained on the 14th day, which lead to the decline of K(superscript +)/Na(superscript +) ratio. While the content of praline measured on the 14th day remarkably increased with the increase of salinity. Our experiment indicated the live oak seems to adapt the salt stress by increasing the absorption of K(superscript +) during the earliest and late stages of salt stress and accumulating proline in leaves during the middle stage of salt stress.

同时发现，盐胁迫处理不同时期对叶片脯氨酸含量和Na、K含量的影响各不相同，在处理7d和21d时，叶片对Na和K的吸收量均有增加，使K/Na维持相对稳定的比值，而脯氨酸含量随NaCl质量质量浓度的增加减少；在处理第14d时，对Na吸收增加的同时，抑制了对K的吸收，导致K/Na比值随NaCl质量质量浓度的增加而迅速下降，而此时叶片脯氨酸含量随着盐质量质量浓度的增加而迅速增加，表明在盐胁迫早期和晚期，弗栎可能通过增加对K的吸收以减轻Na离子毒害效应，而在盐胁迫中期，叶片积累脯氨酸是适应盐胁迫的方式之。

Because of the temporary nature of site work and the frequent change of the work place, it is not possible to mechanize material handling to the same extent as it would be in a more stable operation.

由于现场工作的暂时性和工作场所的经常变化，不太可能使物料处理机械化从而达到相同的程度，因为这将需要一个更稳定的操作。

This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。

Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.

纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征，如原来是良导体的金属，当尺寸减小到纳米量级时就变成非金属型；原来是绝缘体的物质，当尺寸减小到几纳米或几十纳米时电阻大大下降，失去了绝缘体特性；常规固体在一定条件下物理性能是稳定的，在纳米状态下，颗粒尺寸对性能产生强烈的影响等等，这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景，因此，纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议，正式把纳米材料科学作为材料科学的一个新的分支公布于世。

第二，确定权力与其他权利是否侵犯隐私权的标准：即以权利本位的理念，对权力进行严格制约，只有符合比例原则(适当性原则、必要性原则和比例性原则)的权力才不构成侵权，并不得违反有关实体法和程序法的规定；在权利平等的基础上，利用情景排序及价值位阶原则和利益衡量及权利协调原则确定其他权利是否构成侵权，即先进行同质权利的排序和权利的背景排序，前者是一种法律规定，具有稳定的法律效力，后者则具有暂时性和个体性，按权利所代表的法的基本价值和一般价值依次序适用。一般价值的适用次序，则根据具体情况，按利益衡量、权利协调的原则确定，使个案的解决能够适当兼顾双方的利益。第三，确定隐私权的内容，采用列举式和概括式的方法对侵犯隐私权的行为予以具体化，并规定排除侵权的例外，包括正当业务行为，权利人的承诺及推定承诺行为，契约行为，自弃行为及自救行为。第四，对科学技术发展和国际政治经济变化引发的隐私权保护问题予以充分重视，以制度化、法律化解决问题。

Plastic should lower 3 steps, because plastic is a step to add meltresin material to cyclinder , Higher stick of resin material ,higher screwback pressure. Screw speed differs depending on decomposing temperatureof resin material ,Higher screw speed ,Higher trim force of resin,higher cyclinder temperature. Some resin material may decomposes so it setscrew speed in mid-speed such as 45-75%, In plastic step setting screwback pressure is very important, Higher screw back pressure ,higherquality of product screw back pressure make resin structure order, Moldingproduct is beautiful and volume stable. But ,it maybe flow if screw

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。
