Question

急用，请高手帮忙翻译下文，非常感谢！！！

工程机械用的高压胶管比应用在其他领域要求更为苛刻，俄罗斯作为高寒地区则更为明显。机械做功的时候油温高，晚上停工时气温低，冬季反差大，因此对橡胶的含胶率以及温度的高低程度更为严格。除此之外，高压胶管的更长使用寿命，更多脉冲次数还与骨架材料的强度，动态下平衡，膨胀率，伸长率，多层之间的紧密型等关系密切。 要想让第一层向外膨胀尚未达到压峰值时第二层向内收缩，三层、四层同样，则需要极其复杂的计算，靠人力无法完成。必须采用MATLAB计算程序，按计算机输出性能参数、内胶和中胶的厚度、钢丝直径、膨胀量层间压缩量、钢丝破断力、护层厚度等。

Answer 1

解答：Engineering machinery with high pressure hose than applied in other areas is more strict requirements, Russia as cold area is more obvious.
Mechanical work when high oil temperature, evening shut down when the temperature is low, winter contrast big, and so on rubber gel rate and temperature of the high and low degree more strictly.
In addition, high pressure hose longer service life, the more the number of pulse with skeleton strength of material, the dynamic balance, expansion rate, elongation, multilayer between close close, etc.
Want to let the first layer outward expansion has not yet reached the peak pressure when the second inward contraction, three, four also, requires very complicated calculation, rely on human was unable to complete.
Must use MATLAB calculation procedure, according to computer output performance parameters, inner rubber and rubber thickness, steel wire diameter, expansion quantity interlayer compression quantity, wire breaking force, protecting layer thickness, etc.

Answer 3

Engineering machinery high pressure hose is used in other areas of requirements more stringent, Russia as alpine areas is even more obvious. Mechanical working time of high oil temperature, low air temperature in winter night shutdown, high contrast, so the rubber gum content rate and temperature were more restrictive. In addition, the high pressure hose longer service life, more pulse number and skeleton material strength, dynamic balance, expansion rate, elongation, between the multilayer closely closely. To make the first layer outward expansion has not yet reached the peak pressure in second layer inward contraction, three layer, four layer of the same, it requires extremely complex calculations, rely on manpower to complete. MATLAB must be used by the computer program, the output performance parameter, glue and glue thickness, diameter of wire, expansion layer compression, wire breaking force, protective layer thickness.
