查询词典 helicoidal surface

From the results of IR and XPS spectrocopy. The cationic sol components H〓SiO〓 and 〓 of the solution trend to adsorp on the surface of electronegative aegirine because of electrostatic acctraction each other, and interrupted the collector's reaction with Fe〓 on the surface. Hence the flotation of aegirine was decreased, on the other hand, there is electrostatic repulsion between the surface of hematite and the cationic sol H〓SiO〓.〓, Which has advantage to dispersion of hematite particles, therefore, the hematite flotation is achieved sucessfully with anionic collector.

根据红外光谱和XPS测试结果可知，在弱酸性介质中，活性硅酸胶体抑制剂中荷正电的胶团H〓SiO〓及〓由于电性吸引而选择性地覆盖在荷负电的钠辉石表面，从而阻碍了阴离子捕收剂与表面Fe〓的配位作用，导致钠辉石的浮游被抑制；而赤铁矿表面由于荷正电，与矿浆中的H〓SiO〓、〓等硅酸胶团存在着电性排斥作用，有利于赤铁矿颗粒的稳定分散，所以赤铁矿能够被脂肪酸捕收剂吸附而选择性上浮。

The hydrophobicity and topology of the surface of the lotus leaf are a consequence of its special surface structure (branchlike nanostructures on top of micropapillae), which gives rise to a super-hydrophobic surface with a large CA and a small sliding angle.

The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。

At 4 weeks following implantation, cells on the surface of coralline hydroxyapatite were found and connective tissues were seen in the material pores in the experimental group. Cells on the coralline hydroxyapatite were observed only in the control group. At 8 weeks, new bone formation was detected on the surface of coralline hydroxyapatite; bony tissue deposition and a few chondroid tissues were found in the pores or surrounding the pores in the experimental group. A few fibrous connective tissues were observed in the control group. At 12 weeks, abundant mature woven bone was detected on the surface of coralline hydroxyapatite; medullary cavity-like structure and vessels were found in some regions in the experimental group. No new bone or bony tissues were found in the control group.

The results show that the technical parameters and the concentration of sodium molybdate have obvious effect on the composition of the alloy. The crystal grain size is from 6.2 to 12.7 nm and changes with current density, temperature and the pH value of the electrolyte.The crystalline growth of the alloy accords with the model of three-dimensional growth. The surface morphology is mainly determined by the rate competitions between the growing direction of vertical surface and the expanding direction along the surface towards circumambient. The results of the X-ray data show the presence of the multiphase containing solid solution and intermetallic compound in the deposits. The deposit phases alter from the FeNi and FeMo solid solution to the FeNi and MoNi4structure at 3 A/dm2. The deposits internal stress increases linearly with the decrease of the grain size. The lattice parameter of the deposits are slightly distorted
