Chlorophyll content had no significant relation with the net assimilation rate, but was related to the nitrogen content and the specific leaf weight. 葉綠素含量與凈同化速率間沒(méi)有顯著(zhù)關(guān)系，但與含氮量和比葉重有關(guān)。
The effect of Re element addition on the nitrogen content in the weld was insignificant due to the oxidization from the early deoxidization stage. 而由于稀土元素在先期脫氧中大量氧化，其脫氮效果較弱，稀土元素對熔敷金屬的總含氮量的影響不顯著(zhù)。
