Несмотря на то, что машиностроение веками было отраслью человеческой деятельности, только в XX веке машины стали играть такую важнейшую роль. 2. Инженер побывал на многих заводах и конструкторских бюро, лично осмотрел большое количество различных типов машин и проделал большую работу над диссертацией, прежде чем провести большое количество экспериментов. 3. Я хотел бы знать, достаточно ли серии экспериментов, которые я уже провел, и данных, которые я получил. 4. Эти замечательные технологические достижения стали возможными благодаря специально разработанным механизмам и машинам. 5. Человек получил сверхвысокие и сверхнизкие температуры, сверхвысокие вакуумы, сверхвысокие давления, сверхвысокую прочность, сверхупругие и сверхпроводящие материалы и смог изучить взаимодействие частиц сверхвысокой энергии
