弱胸蛙屬
  1. The mechanism of anti - wear and friction reduction of nanometer cacoa has been discussed and individual opinions of the nanometer particles " existing way and effects have been proposed. 1 ) the shape of the nanometer cacos particle is approximate to that of sphericity. its function is similar to that of the miniature " ball bearing "

    6 、探討了納米碳酸鈣粒子的抗磨減摩機理，對于納米粒子在潤滑油中的存在方式和作用提出了個人見解： （ 1 ）納米碳酸鈣粒子近似為球形，它們起了類似微型「球軸承」的作用，從而提高了摩擦副表面的潤滑性能。
  2. Thus wear and friction are reduced. 3 ) in the course of friction the nanometer cacos particles and cao particles can fill up the concave of the surface and even sink into substrate and fill in the worn position promptly

    （ 3 ）摩擦過程中納米碳酸鈣、納米氧化鈣粒子能填平摩擦表面低凹處甚至陷入基體中，並可及時填補損傷部位，具有自修復功能，使摩擦表面始終處于較為平整的狀態。
  3. It can be observed that the sediments of the holocene loess is continuous and thus it reflects the environmental change and human activities since the holocene. meanwhile, laoguantai profile is a perfect one because it lies in the periphery of the laoguantai cultural relics. on the basis of outdoor observation and indoor experimental analysis, the author selects proxy substitute indexes, such as grain - size, magnetic susceptibility, microelements, cacos and ph value, etc. moreover, the thesis also calculates and investigates the remains of human activities kept in the profile

    為了盡可能準確地獲取該地區全新世以來的環境演變和人地關系演進的真實環境背景，本次研究在野外詳細觀測和大量室內實驗分析的基礎上，審慎地選取了多項用於再現古氣候環境的代用指標進行了分析，這些指標包括粒度、磁化率、微量化學元素（包括fe 、 rb 、 co 、 li 、 cr ； sr 、 ba 、 cd 、 sb ； bi 、 mn ； cu 、 zn 、 pb 、 ni ） 、碳酸鈣和土壤ph值等。
  4. The results of the test of the nanometer caco3 particles " tribology chemistry through x - ray photoelectron spectrum show that the nanometer cacos, calcium oxide ( cao ) and metal calcium improve the oil ' s properties of extreme pressure, anti - wear and friction reduction together

    5 、通過xps測試，對納米碳酸鈣粒子的摩擦化學性能進行了研究，在摩擦過程中碳酸鈣、氧化鈣和金屬鈣共同起到了提高極壓性能、抗磨減摩的作用。
  5. Preparation of polymer composites is one of the important methods to realize high performance of polymer materials. in this paper, a newly developed ethylene - octene copolymer ( eoc ), catalyzed by metallocene catalysts, was used as an impact modifier for pp instead of traditional modifier ( epdm ). the relationship between the structure and properties of polypropylene composites toughened and reinforced by eoc and cacos respectively or together was studied systematically

    聚合物復合材料的制備是實現高性能聚合物材料的重要途徑之一，本論文採用茂金屬催化劑合成的新型聚烯烴彈性體乙烯-辛烯共聚物（ eoc ）代替傳統的三元乙丙橡膠，對eoc和caco _ 3兩種增韌劑分別和協同增韌增強聚丙烯復合材料體系的形態結構與性能的關系進行了系統的研究，圍繞高性能、應用探索和理論研究三個方面作了較為深入的探索和分析，獲取了很多有價值的信息，為高性能聚丙烯復合材料的開發和應用作了理論鋪墊，主要結果如下： 1
  6. 2. the chosen nanometer cacoj particles have been tested and analyzed through advanced instruments. 1 ) the crystal structure and average size of the nanometer cacos particles have been tested by rotatory anode harrow x - ray diffractometer

    2 、採用先進的儀器對所選擇的納米碳酸鈣粒子進行了測定： （ 1 ）使用旋轉陽極靶多晶x射線衍射儀測定其晶體結構和平均粒徑大小。
