视需要可根据本发明技术线路将长度向上延伸 英语怎么说

问题描述：

谢谢

问题解答：

向上延伸，要突出“向上”，比较好的翻法是upward extended

视需要，用在你这里最好的说法就是 referring to actual demand，“参考实际需求”的意思

因此，整段话可以翻成：
According to the technique of this invention, the line can be upward extended referring to actual demand.

视需要可根据本发明技术线路将长度向上延伸

For application of this invention, the line can be lengthened according to specific conditions.

Accoring to the technique of this invention, the line can be lengthened upwards as required.
