發音:用"chemical reactivity"造句"chemical reactivity"怎麼讀
- They differ in solubility and chemical reactivity .
- The chemical reactivity of apo would facilitate its hydrolysis in a waste stream .
- The chemical reactivity of apo would prevent the parent compound from reaching the discharge water of a treatment plant .
- Study on preparation of rice husk ash with high specific surface area and its chemical reactivity
- Methods of sampling and test for carbonaceous materials used in aluminium manufacture - electrodes - chemical reactivity to air of prebaked anodes - determination of the reactivity by a loss in mass method
- The experimental results indicate that the initial reaction rates of nano - nah are several orders of magnitude higher than those of the commercial one . the large specific surface area and the high surface energy of nano - nah should be the main factors for their extremely high chemical reactivity . with nano nah , many reactions can be carried out efficiently
- Combined core - shell method with scm , pmw - pnn - pt ceramics with core - shell structure , which have excellent dielectric temperature stability , were successfully prepared . the new mechanism of improving temperature stability of dielectric properties was put forward . the main contents are lis ted as bellows : in the systems of pmn - pt , the effects of the chemical reactivities of the starting materials such as soluble mg - salts instead of mgo , pb - salts instead of pbo and ti ( oc4h9 ) 4 instead of tio2 respectively on the formation of perovskite phase were investigated in detail
Scm法與cpm法的工藝相比，工藝簡單，預燒溫度和燒結溫度低，反應時間短；陶瓷致密，介電性能比cmo法和cpm法明顯得到改善，而且在沒有pt存在時，仍可制得純鈣鈦礦結構的pmn基、 pnn基、 pfw基陶瓷。
