  1. Then by means of heterocoagulation and encapsulatin, on controlled condition the superfine powders of caco3 and tio2 were coated with different nonaparticles ps. the composite particles with core / shell structure were prepared by heating the composite particles above the glass transition temperature of ps

    然後根據異相凝集-包埋法原理對具有不同表面電性的微米級的caco _ 3和tio _ 2進行包埋復合，制得以無機粒子為核，有機粒子為殼層的包覆型有機?無機復合粒子。
  2. Double - shell heat energy storage microcapsule was prepared used the prosperities of microcapsules were investigated. a phase change material as core, which melt point was 24 c and phase transition heat was 225. 5j / g. the microcapsules would been used in indoor wall to regulate the temperature and saving energy sources. the surface morphological structure was examined by means of scanning electron microscopy

    其中當乳化速度為2500r min 、乳化時間大於5min 、壁材滴加速度小於0 . 5ml ? min ~ （ - 1 ）且系統調節劑為芯材的30 40時微膠囊的粒徑分佈集中； dsc顯示微膠囊包覆相變材料不影響其相變點，相變儲熱明顯。
  3. 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；陶瓷緻密，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。
  4. It was the first time that the silica nanoparticles was coated with gd2o3 : eu rare - earth oxides, then the core - shell structure compound particles were obtained. the characterizations showed that the thickness of uniform coating is in 10 - 20nm ; the silica core is linked with the gd2o3 : eu shell by chemical bond si - o - gd ; because of the size effects and interface effects of nano - crystal coating, the diffraction and emission peaks become broadened. and at the same time, the transfer temperature of silica from amorphous to crystal is decreased

    首次在納米sio2表面包覆一層gd2o3 : eu稀土復合氧化物，得到了核-殼結構的復合顆粒，表徵結果表明，均勻包覆層的厚度為10 - 20nm ； sio2核和gd2o3 : eu殼層物質之間通過化學鍵si - o - gd鍵的作用結合在一起；由於包覆層納米晶的尺寸效應和界面效應使xrd衍射峰和熒光光譜發射峰出現了寬化現象。
  5. Because of the large mass, after the hydrogen burning, the temperature and pressure of the core is high enough to trigger helium burning to carbon, and a hydrogen burning shell is developed around the core

    由於大質量恆星的核心比一般恆星更熱和有更高的密度，當走至生命盡頭時，核心條件足以把氦繼續轉化為碳，同時在核心外圍形成一個氦殼。
