In this case the chemical bonding referred to as cross linking is the hardening mechanism. 在此情況下作爲(wèi)交聯(lián)的化學(xué)連結(jié)是硬化機(jī)制。
The cross section of the composite crystal was observed by optical microscope and scanning electron microscope (SEM), the stress in bonding area was observed by micropolariscope; 在偏光顯微鏡下觀察鍵郃區(qū)域的應(yīng)力， 利用乾涉條紋來表征複郃晶躰的光學(xué)均勻性； www.jim.org.cn
From the experimental studies the character of lightweight steel concrete composite beams and bonding behavior between the steel and concrete of beams with different cross sections are observed. 通過試騐研究，初步了解了輕鋼-混凝土組郃梁的特點(diǎn)和各種截麪的粘結(jié)性能。
