结果表明：二甲基亚砜和甲酰胺不宜作高相对粘度尼龙6的冻胶纺丝溶剂，硫酸、甲酸和间甲酚比较适宜；提高温度有利于降低剪切速率，质量分数为12％的间甲酚溶液和质量分数为9％的甲酸溶液作溶剂，其尼龙6溶液分别在50～60℃和45℃以上有较好的可纺性；溶剂对尼龙6晶体结构的形成有着重要的影响。

Because the gas viscidity is smaller than the liquid viscidity and air is compressible, so in the same conditions, the tangental velocity and vorticity magnitude of gas is greater than liquid.

由于气体的粘性比液体的粘性小及气体的可压缩性，所以相同条件下，气流场的切向速度和旋涡强度都比液流场的强。

Considering the unsolved problems of designing diamond segments and the available laboratory conditions, this paper tried to make a united research on cut materials and cutting tools. By studying on stone machinability, diamond metalizing, bond formulation and sintering condition adjusting and the compatibility between stone and segment, some basic rules for designing diamond segments were concluded.

根据目前金刚石切石锯片设计中存在的问题及实验室所具备的条件，本文力图将切割对象和切割工具统一起来进行研究；通过对石材的可锯性、金刚石表面金属化、结合剂性能的调整以及工具与岩石的适应性等方面的研究，从而找出面对特殊切割对象的专用性产品的设计思路。

The major advantage of PFC2D is the evolution regularity of microscopic fabric parameters including co-ordination number, contact normal, normal contact force, shear contact force, can be achieved together with the macroscopic liquefaction response. The micromechanism of sand liquefaction is further discussed.

颗粒流数值模拟的优点在于得到试样液化宏观力学表现的同时，通过不同循环加荷时刻试样内细观组构参量（包括配位数、接触法向分布、粒间法向接触力、粒间切向接触力）的演化规律，分析砂土液化过程中细观组构变化与宏观力学响应之间的内在联系，从而可进一步探讨砂土液化的细观力学机制。

The company has three advanced spiral paper tube production lines and related equipment (sub-machine, precision cutting machine, precision machine and efficient drying room) andìprocessing equipment, according to the needs of users develop, produce many varieties, many specifications, the versatility of the new products.

公司拥有三条先进的螺旋纸管生产线及相关设备（分条机、精切机、精整机和高效的烘干房）和异型管的加工设备，可根据用户的需求开发、生产多品种、多规格、多用途的新产品。

After feeding, the volume of material roll of a central location that is, the business card printing and membership card making location, because this machine is affixed with a deviation, version, and so on are in sub-subparagraph to the central axis as the base, the material should be in strict accordance with our equipment for each feed routes through the guide roller is, put to paper machine for printing paper smooth and adjust the tension and cause to be printed materials subject to certain harmoning tension control in order to ensure the rectification of overprinter precision, adjustment, so that the material in the press and printing center position, to ensure that the rectification action ofsmell is correct.

上料卷之后，料卷的中心位置也就是制卡和会员卡制作位置，因为贴版纠偏、模切、分节等都是以中心轴为基准的，被印材料应严格按照本台设备的送纸路线穿过各个导纸辊、穿纸后可开动机器让被印材料送纸平稳，调节张力，使被印材料受到一定的平稳张力控制，才能保证套印精度、调整纠偏，使材料在印机及印版中间位置，以确保纠偏动作的灵敏无误。

For using PLC to be control system from Simens of Germany, it can be done to feed pipe, pick-up, adhering and cutting foils automaticlly in production. It uses computer control to setup and mesure the length of foils. The control system is continuous speed adjustable of foils' linear speed.

由于该机采用先进的德国西门子公司生产的可编程控制器作为控制系统，所以实现了在整机运行中上管、接料、施胶、收卷、裁切等的自动化，同时铝箔的计长、设置采用电脑控制，铝箔运行的线速度的控制采用了无级调速装制。

Sensibility is a sensation that you do something regardless of unpredictable consequence and result, we could compare sensibility to the sail of ships. Logos means do something after rational rating yourself, we could compare logos to the rudder of sailers. Both of them are irreplaceable. Based what I know, sail is superior to rudder in function, for the reason that we couln't move without sail, while we could expect something avilding rudder on the voyage.

昨晚准备看球的，可不知怎么的，竟然没起来，今天得知葡萄牙出局了，小猪太生猛了，c罗就这样离开了欧洲杯，我不是他的坚实拥趸，只是喜欢血性的manutd，他不是闹转会吗，我怎末越来越觉得他不属于血色的曼联了，我从曼联官网寄来的新赛季的赛程得知，08~09赛季，他们的赛季初和赛季末不太好打，要死磕利物浦和切尔西，还有同城死敌曼城。

In the cells of the fifth generation however, the formation of polyhedra could not be observed.

为了探索获得宿主域扩大的重组病毒的途径，本研究利用G3及BmNPV均能在SpIm细胞中形成病毒多角体的特点，将2株病毒共感染SpIm细胞，经空斑法培养获得一株新的病毒株，其DNA的酶切电泳图谱与BmNPV DNA相似，在前4代感染Se301和BmN4细胞均可形成多角体，但第5次继代感染Se301细胞时，不再观察到多角体的形成。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
