求翻译：在Φ273 ×10钢管上NO.3、NO.4点测得人工磁化磁异常垂直分量数值相差较大是令人费解的，同时一根钢管上不应出现这种情况。推测可能水泥地下有磁性较强物体存在。是什么意思？

In Φ 273 x 10 steel pipe, NO NO3, measured .4 point artificial magnetized magnetic anomaly vertical weight difference in values of larger is puzzling, and at the same time a steel pipe, should not be in such a situation. We assume cement underground has a magnetic presence stronger objects.

On φ273 ×10 the steel pipe NO.3, the NO.4 spot obtains the artificial magnetization magnetism exceptionally vertical component value difference is greatly beyond comprehension, simultaneously on a steel pipe should not have this kind of situation.Extrapolates under the possible pavement the magnetic

Φ 273x10 steel NO.3, NO.4 point artificial magnetization measured on vertical component values differ by a large magnetic anomaly is confusing, and should not happen on a steel tube. Presumably cement underground presence of a strong magnetic object.
