Preferential oxidation of Ti on NiTi alloy surface has been observed and was consistent with the experimental result and the free energy of formation A G?(298K) of NiO, TiO, TiO2. Mulliken population and the partial density of state analysis showed that the interaction between Ti and O atoms was mainly donated by O 2p and Ti 4s orbital and O 2p and Ti 3d, 4s, 4p hybridization orbital. The electron structure in NiTi bulk material was not altered during 62 molecule adsorption process and the surface passivation oxide formation.
进一步对钛与氧之间相互作用本质的研究表明,O 2p轨道和Ti 4s轨道以及O 2p轨道和Ti 3d 4s 4p杂化轨道间的相互作用是NiTi合金表面氧分子吸附的驱动力,在此过程中,NiTi合金的体相结构没有发生变化,从而保证了其一系列力学性能和形状记忆特性在表面氧化后不发生明显的变化,使表面改性的工作可以安全、可靠的完成而不影响其植入人体后发挥正常的生理功能。

Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.

By using spectrophotometry method determinated the anthocyanindin and chlorophyll content in different parts of Prunus wilsonii leaves,results showed that,as time changes,anthocyanins content in different parts of the leaves showed a low-high-low change in trend,the analysis of variance,the difference is not significant,relations between anthocyanidin content in Prunus wilsonii leaves and the position of health was not obvious,anthocyanindin content in the same part are far greater than chlorophyll content,...
用分光光度法对紫叶稠李叶片不同部位的花青素和叶绿素进行了测定,结果表明,随着时间的变化,不同部位叶片的花青素均呈现低-高-低的变化趋势,经方差分析,差异性不显著,说明紫叶稠李叶片花青素含量跟着生的部位关系不明显;同一部位的花青素含量远远大于叶绿素含量,这也是紫叶稠李叶片在整个生长季呈现紫红色的原因。

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

The most heavy flow ability of barrage swirl is controlled by fastenning device and barrage size, the most heavy discharge is more when barrage aperture is bigger, the influence of barrage position on discharge is not obvious; The pressure of the end of the shaft and fastenning device increases which aroused by barrage, and there is a restraining action to flow waving of the shaft; The barrage aperture is smaller, the increase of pressure is heavier, the influence of position to the increase of pressure is not obvious; The positive pressure of the level section in the hole between fastenning device and barrage increases obviously, the change of press along length reduces, mural press in the hydrosphere separating area of outlet of fastenning device becomes positive pressure, which is propitious to the increase of flow cavitate number in the low pressure area of the outlet of fastenning device; The influence of change of swirl cavum diameter caused by barrage to ventilating state is obvious.

Take DMSO swollen treatment and DEA-SO2-DMSO decrystallization treatment for example, the X-ray diffraction and the Tobolsky's intermittent stress relaxation of treated woods were determined during soaking in water, analyzed the effects of water on crystal degree and inter-cohesion of treated woods. According to these continuous relaxation curves measured in water with different temperatures, various thermodynamic quantities were obtained by using Eyring absolute rate theory, and reviewed the chemical reactions in wood which occur in different relaxation process. For the first time quantify these crosslinkings formed in the process of tensional relaxation by using the SMCIR intermittent stress relaxation way, and defined the cross-linking reaction types. In order to find out the contribute of drying to the fixation of deformation of chemically treated wood, stress relaxation of oven-dry untreated and treated wood was measured during the process of temperature elevation and descend, then analyzed the effect of temperature change on relaxation mechanism of treated oven-dry wood. According to continuous relaxation curves of oven-dry treated wood under various constant temperature, calculated the thermodynamics of relaxation process and discussed the mechanism of molecule change in wood, at the same time, also quantified these cross-linkings produced in wood by intermittent method and on the basis of which the model of molecular change during relaxation process of chemically treated was constructed.
