An alternative and arguably more rigorous approach would be to repeat the exercise using an "equal area" projection that shows the countries' areas correctly while minimising shape distortion.

一种选择性、富有争议和更加严谨的做法是反复使用“等积地图”投影，该投影显示国家的正确区域又能使外形的扭曲最小化。

Due to the advantage of high energy density, low heat affected zone, low shape distortion of components, high welding speed, the research of the laser welding is the focus of the laser process.

激光焊接技术由于其能量密度高、热影响区小、焊接变形小、焊接速度高等众多优点，一直是激光加工方面的研究热点。
