  3. After the sample is turned out, its internal and external structures are observed and its bulk density is measured in order to determine how the sintering temperature, the time of thermal preservation, and the quantity of admixture affect the performance of lytag

    通過對試樣內、外部結構觀察和容重的測定，研究燒成溫度、保溫時間及外加劑摻量對粉煤灰陶粒性能的影響。
  4. Management and preservation regulation of petroleum geology laboratory sample

    石油地質實驗室樣品管理及保存規范
  5. Standard practices for preparation of sample containers and for preservation of organic constituents

  6. We researched the influences of systhesis temperature, heat preservation time, eu + concentration, reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors, optimized the experiment conditions and reduced systhesis temperature about 100 c. we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature, but the phase component is more complex. we found that the luminescence brightness of sample appear a increasing process at first, and then a reducing one with the raise of eu2 + concentration, it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low. we found that the systhesized sample can not bright at too long heat preservation time, and the luminescence brightness is lower at too short heat preservation time. we found that particle diameter is bigger, the wavelength of emission peak is longer

    研究發現合成溫度高，合成樣品的發光效果好，但物相組成也較復雜； eu ~ （ 2 + ）離子在一定摻雜濃度范圍內，合成樣品的發光亮度先是出現一個提高過程，然後是一個降低過程，說明eu ~ （ 2 + ）離子濃度高或低都不利於合成樣品發光；保溫時間較長，合成樣品不發光，保溫時間較短，合成樣品發光效果不好，只有合適的保溫時間才能合成發光效果好的樣品；合成樣品的粒徑大小與發射峰的位置具有一定的關系，粒徑越大，發射峰越偏向長波方向；助熔劑對樣品的合成溫度和發光性能都有影響，助熔劑的量較低時，主要表現為助熔作用，對發光影響不大，助熔劑的量較高時，使得樣品發光亮度降低和余輝時間縮短；還原方式的不同，合成樣品的發光性能也不一樣。
  7. Ix. preservation of documentary records, company archives, building plans, as well as sample specimens of industrial products should be encouraged

    應該提倡保護記錄文獻、企業檔案、建築平面圖以及工業產品的樣品。
