弱胸蛙属
Examples
- 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 、采用先进的仪器对所选择的纳米碳酸钙粒子进行了测定： ( 1 )使用旋转阳极靶多晶x射线衍射仪测定其晶体结构和平均粒径大小。 - 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 ）摩擦过程中纳米碳酸钙、纳米氧化钙粒子能填平摩擦表面低凹处甚至陷入基体中，并可及时填补损伤部位，具有自修复功能，使摩擦表面始终处于较为平整的状态。 - 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 、通过xps测试，对纳米碳酸钙粒子的摩擦化学性能进行了研究，在摩擦过程中碳酸钙、氧化钙和金属钙共同起到了提高极压性能、抗磨减摩的作用。 - 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
为了尽可能准确地获取该地区全新世以来的环境演变和人地关系演进的真实环境背景，本次研究在野外详细观测和大量室内实验分析的基础上，审慎地选取了多项用于再现古气候环境的代用指标进行了分析，这些指标包括粒度、磁化率、微量化学元素(包括fe 、 rb 、 co 、 li 、 cr ； sr 、 ba 、 cd 、 sb ； bi 、 mn ； cu 、 zn 、 pb 、 ni ) 、碳酸钙和土壤ph值等。 - The impact behaviors of pp / eoc and pp / caco3 were compared . the toughening mechanisms of pp / eoc and pp / caco3 systems are firstly proved to agree well with wu ' s percolation theory . the essential condition occurring brittle - tough transition in two binary systems is that the matrix ligament thickness ( l ) is lower than the critical matrix ligament thickness ( lc ) which is approximate to 0 . 095 ? m
比较ppffioc和ppcacos二体系的增韧行为，发现加入eoc和cacos都能增韧pp ，首次验证了新型弹性体eoc和无机刚性粒子cacos增韧pp的机理符合wu氏逾渗理论，二体系发生脆韧转变的基本条件是基体带厚度l小于临界基体带厚度人（ 。
