length of oil meaning in English

油的延展长度

In one hand , because the design work is n ' t visualized , the design quality is n ' t easily assured and the design errors are easily caused . on the other hand , in the process of manufacturing oil - feed unit , the length of oil - pipe is unknown beforehand , thus the production is hardly managed , and the material is also wasted easily
一方面因设计工作很不直观，容易导致设计错误，严重影响了设计质量；另一方面，在供油单元的制造过程中，油管长度无法预先确定，给生产管理带来困难，同时也会造成管材的浪费。
The theories of multi member function ' s extremity value , hooke jeeves mode searching method solving wholly complex problem of extremity value and uniformity design method , one new and efficient method to choose test point , are applied to establish the two - dimension oil well orbit optimized model . the shortest length of oil well orbit curve is regarded as this model ' s object and all kinds of effecting parameters are analyzed
通过引入多元函数极值理论、求解复杂极值问题的hookejeeves模式搜索法及一种较为新颖和高效的试验点选择方法：均匀设计法，建立以最短油井轨迹曲线长为目标的二维油井轨道优化设计模型，并对影响井轨迹曲线的参数进行了较为详细的分析。
