To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.

研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。

This kind of epic mostly depicts the formation of the universe, origin of human being, custom and some animals and plants that are close to human life. The world-originate epics reflect the theme of the resounding for human labor and creativity, as well as singing for the grittiness of primary people who sticks to cultivating the nature and create the new world. This style of primary form of literature made by minority nationalities in South-west China is unique. It is one of the most important styles of literatures that include myths, ancient ballads, sagas and stories.

ABSTRACT Aiming at problems of trans-vector controller in a vehicle-carried induction motor such as variable rotor and stator resistance following motor temperature, and their inductance varying with flux saturation degrees. Firstly, CSI and VSI are introduced, for CSI, it can hold the advantages both FOC and DTC using stator flux directional, PI parameter and simulation are also introduced. Secondly, equations of IM in the synchronous rotary frame and its static counterpart, as figuring in the saturation condition of magnetic field, are dealt in this paper and the simulation results are presented. Thereafter, the parameter designing of PI trans-vector controller is processed, which features the non-linear model. In practical realization, as neglecting the dynamical change of motor inductance, this paper employs online modification of inductance parameters, according to the flux saturation, then transforms the non-linear equations into linear ones, and so compacts the structure of controller. Thirdly, in view of the maximum torque output is extraordinary requisite when Electrical Vehicle start up, accelerate, and overtake, this paper issues the maximum torque when both inverter and battery capacity is corporeally definite. Fourthly, on-line differentiating and analyzing both rotor's time constants and its flux by using the expanding order reduction and discrete Kalman filter equation are fathomed, in order to realize high-performance trans-vector algorithm, and also the simulation results are presented. Fifthly, the close-loop regenerative brake system, when the EV's torque is set constant, is deduced; at the same time, unification of electric drive model and brake model is executed. Combined with maximum charge current demands, the mathematical model for online yielding torque as a demand.

The main body of interculture communication for different cultural backgrounds people is the communication between governments. Accompanied by the rapid development of the Internet, on-governmental exchanges are frequent, people power rises. Plus the improvement of the public media literacy, the communication of different members of society from multicultural background is increasingly close, social forces strengthen from weak to strong and becomes a development and expansion of the force besides communication between governments.

从凤凰的形态、色彩、习性、产地及其同人类之间的密切关系可以推知，我国历史传说中的凤凰不是人类想像出来的神灵，不是集合多种飞禽特点的抽象符号，不是鸵鸟，也不是我国本土产长尾雉，而是古代日本的东天红鸡或长尾雉。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
