由退火后试样的初始磁导率与温度的关系及磁致伸缩系数的变化结果表明，当有极少量的-αFe晶体相析出时，可明显改善合金的动态磁性能；当-αFe晶体相进一步析出时，可使合金呈现良好的恒导磁特性。

Her maidenly reserve, and a certain sense of what was conventional under the circumstances, called her to forestall and deny this familiarity, but the daring and magnetism of the individual, born of past experiences and triumph s, prevailed.

少女的矜持和在此种情况下传统的礼仪都告诉她不能答腔，不能允许男人这样随便接近她。不过那个男人是个情场老手，他的大胆和磁性般的魅力占了上风。

少女的矜持和在此种情况下传统的礼仪都告诉她不能答腔，不能允许男人这样随便接近她。不过那个男人是个情场老手，他的大胆和磁性般的魅力占了上风。

With ideas similar to the Gri ffi ths singularity, in which T * would be the critical temperature of the associated clean system in the absence of disorder, and which have recently been discussed in the context of manganite physics.

在这种情况下， T *是不存在无序相的清洁系统得临界温度，在最近被认为是磁性物理学的内容广泛讨论。

Some methods, such as hydrothermal method, sol-gel method and pulse laser deposition method, have been developed to prepare manganite nanomaterials. Studies on the nanoscaled manganites revealed that they exhibit a number of novel physical properties such as low field high magnetoresistance, superparamagnetism, and large coercivity and more promising applications as compared to the corresponding bulk compounds.

发展了低温水热法、溶胶凝胶法、脉冲激光沉积模板法等方法制备锰氧化物纳米材料，研究发现纳米级的锰氧化物表现出了一些不同于块材的奇特的物理性质：如低场高磁阻效应、超顺磁性、大矫顽力、低饱和磁化强度及表面自旋玻璃等。

If a class has no , and teaching is meaningless to the development of the teacher or the students, or teaching has side effects, then teaching human being means teaching objects, so teaching is worse than no teaching; If a class is of no effect, then teaching means nothing; If efficiency can not be found , what is the difference between a class and a campaign in which you annihilate a maniple of enemy at the cost of a brigade? more a loss than gain; Without magnetism, like a sheet of loose sand, crystal will not come into being, full development will be out of the question, let alone sustainable development.

如果一堂课没有价值，教学对学生、对老师的发展没有意义或者造成负面的影响，那么教人等于教物，教小于不教；如果一堂课没有效果，那么教等于白教；如果一堂课没有效率，无异于战役中吃掉了敌人一个连，自己损失了一个旅，得不偿失；教学没有磁性，好比一盘散沙，没有结晶，谈不上充分发展，更不用说可持续发展了。

The e-business contract transmits and exchanges data information in the form of data message, and stores data information in magnetic medium of the computer.

电子商务合同是采用数据电文合同形式进行数据信息的传输、交换和存储的，并将数据信息存储在计算机的磁性介质中。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
