No significant results are found on the interaction of language and format to reading comprehension and eye movement indexes.2. For one-, two- and three-column texts, no significant differences are found on reading comprehension indexes but among such indexes as saccade length, number of within-line and multiple-line regression. Compared with two- and three-column text, one-column text is the best. Moreover, the number of fixation, fixation frequency, fixation duration and total regression numbers of one-column text are also better.

Except for research and discuss on turning and milling gray cast iron under high cutting speed, only few studies about machining nodular cast iron and vermicular cast iron with PCBN tool were carried out, while the two materials are widely used in manufacturing, specially automobile, aviation and machine tool. Therefore how to cutting these hard-to-machine materials economically and effectively is becoming an urgent-to-solve problem.
但是对于铸铁加工领域的研究则相对较少,除了对高速切削和铣削灰铸铁有较为深入的研究探讨外,关于PCBN刀具对球墨铸铁、蠕墨铸铁等材料加工应用的研究却很少,而这两种材料近些年已经大量的应用于汽车、航空、机床等制造业中,因此如何经济有效的加工这样难加工材料成为迫切需要解决的问题。
