求中譯段落： The insulation is subjected either to a voltage of substantially sine-wave form having a frequency of 50 Hz or 60 Hz, or to a DC VOLTAGE equal to the peak voltage of the prescribed a.c. test voltage. Unless otherwise specified elsewhere in this standard, test voltages are as specified in table 5B for the appropriate grade of INSULATION and the WORKING VOLTAGE (U), across the insulation. DC values of WORKING VOLTAGE shall be used for DC VOLTAGES and peak values for other voltages. 我的試譯: 絕緣體受到頻率50Hz或60Hz的正旋波大電壓,或是相當於直流測試電壓峰值的交流電壓除了其它於此標準下所明示之測試電壓適用於此絕緣等級與工作電壓,以上列於5b目錄交流工作電壓值通常應為交流電壓值且其它電壓值其為峰值. (這題好難翻) 請教高手了段落：Insulation breakdown is considered to have occurred when the current which flows as a result of the application of the test voltage rapidly increases in an uncontrolled manner, that is the insulation does not restrict the flow of the current. Corona discharge or a single momentary flashover is not regarded as insulation breakdown. 我的試譯:絕緣破壞構成是當應用操測試電壓快速的增加,發生於無法控制的操作方法, 乃指絕緣體無法限制其電流量.電暈放電或瞬間閃燃效應不視為絕緣破壞請問有誤嗎? 段落 A floor standing unit having a mass of 25 kg or more was subjected to a force equal to 20 percent of its weight, but not more than 250 N. The force was applied in any direction, except upward, at the most unfavorable height, but not more than 2.0 m from the floor. 我的試譯:一個立於地面的裝置,其質量為25kg或更多,受到相當於本身重量之20%的力量作用,但最大不超過25N,此力量除了向上方向施加外可由任何方向施加,而其最不適合的高度,離地面距離不超過2m. unfavorable height要怎麼翻比較好,最後面這句感覺怪怪的段落: All doors and drawers, etc., which may be moved for servicing by the operator or by service personnel were placed in their most unfavorable position consistent with the installation instructions. 我的試譯: 所有的門及抽遞,等..可能於服務時經由工作人員或服務人員所移動,而其所放置到最適宜的位置,於安裝說明上所敘述的一致. 請高手指教了~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.136.13.12
