The hole size is limited by the ring thickness. 螺孔的大小受套圈厚度的限制。
The film thickness cannot exceed a maximum value which depends on the Ge content. 薄膜的膜厚不可以超过由锗浓度所决定的最大数值。
The results show that certain thickness of the base metal and the regime of heat treatment will increase the peak hydrogen concentration and promote the tendency of disbonding. 结果显示，一定的母材厚度和焊后热处理条件，使熔合线附近氢浓度峰值提高，从而使氢剥离倾向增大。
I wrapped the ice cream in three thicknesses of newspaper to keep it cool. 我用三层报纸包裹冰淇淋使其不致变热融化。
