The step motor can receive digital signal directly and has the ability to response outer environment immediately and has no accumulation error, which often is used in driving system. In this driving system, open-loop control system is composed of stepping motor, which can satisfy the demand not only for control precision but also for the target of economic and practicality. On this basis , the analysis of stepping motor in power calculating and style selecting is also given.

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。

First, based on the mathematics model of comprehensive decision at present, the concept of evaluation function is introduced. Based on the thinking stability of decision-maker, the essential meaning of comprehensive decision model is discussed, therefore, and a new improved approach on the comprehensive decision model is put forward. Second, the mathematics model of interval number comprehensive decision is systematically discussed, and the ranking method of interval number based on the decision-maker's attitude is provided. Finally, the concept of valuation order relation is introduced, the valuation order relation of interval number and fuzzy number are systematically discussed in detail, it provides a new method to research the order relations of interval number and fuzzy number, therefore, these achievements can be applied in the intelligent system.

首先，针对常用的综合决策模型，给出了评判函数的概念，讨论了综合决策模型的本质意义，指出决策者的思维应具有稳定性，从而给出了综合决策模型的一种改进方法；第二，在此基础上，给出了区间数的综合决策模型，并详细讨论了基于决策者的决策心态的区间数的排序方法；第三，引入了赋值序关系的概念，详细讨论了区间数和模糊数的赋值序关系，为区间数和模糊数的序关系研究提供了新的思路与方法，这些均有望在智能系统中得到广泛的应用。

Bonding structure and the change of chemical composition at the Cu/ceramic interface are investigated systematically with microanalysis. Furthermore, it is observed that copper bonding to Al〓O〓 ceramic is formed by chemical reaction between Cu〓O within the Cu-Cu〓O eutectic and Al〓O〓 at high temperature, CuAlO〓 as a reaction result is produced, mechanic join and physical osmose are not the main factor.

运用多种显微分析技术，对铜-陶瓷键合界面的微观结构，以及键合前后物相化学成份的变化，进行了系统的研究，在此基础上，明确了Cu-Al〓O〓陶瓷的键合机理；机械交联和物理渗透不是形成键合的首要因素，键合是通过Cu-Cu〓O共晶熔体中的Cu〓O相在高温下与Al〓O〓陶瓷发生了化学反应，形成了牢固的化学键合，同时伴随有一些CuAlO〓物相的生成。
