求翻译(the relaxation time at one orientation)
来源:百度知道 编辑:UC知道 时间:2024/05/30 18:42:14
the energy barrier between two orientations.
原文“Their magnetic properties change drastically
with their size, as the relaxation of the magnetization orientation of each particle is determined by s = s0 eKV/2kT, in
which s is the relaxation time at one orientation, K is the particle’s anisotropy constant, V is the particle volume, k is Boltzmann’s constant, and T is temperature. The term KV measures
the energy barrier between two orientations. As the size
of the particle decreases to a level where KV becomes comparable
to the thermal energy kT, its magnetization starts to
fluctuate from one direction to another.
As a result, at this T the overall magnetic moment of this particle is randomized to zero, and the particle is said to be superparamagnetic.”
不需要翻译全文,只要解释一下orientation
内容主要涉及微小粒子的磁力特性
请不要拿电脑随便翻译的东西来,谢谢
magnetization orientation 磁化方向,相当于direction of magnetization
这段材料说的是磁性粒子的磁性会粒子大小的变化而剧烈变化,当磁性物质小到某一个点时(类似于把磁石加热到居里点温度),材料将变成“顺磁体”(paramagnetic),其磁性很容易随周围的磁场改变而改变。而当磁性颗粒的粒度更小时,即便在常温下,磁体的极性也呈现出随意性,难以保持稳定的磁性能,这种现象就是所谓超顺磁效应(SuperparaMagnetic)
The term KV measures the energy barrier between two orientations. KV的能级代表磁性物质要改变其磁性需突破的能量壁.
它们的磁特性变化显着
其大小,作为放宽磁化方向的每个粒子是由秒= s0 eKV/2kT ,在
其中s是弛豫时间在一个方向,钾是粒子的各向异性常数, V是粒子量, k为玻尔兹曼常数,和T是温度。任期千伏措施
能源屏障两方向。由于规模
粒子减少到一定的水平,成为可比千伏
以热能KT公司,其磁化开始
波动从一个方向到另一个。
它们的磁性变化急剧的大小,作为放宽磁化方向的每个粒子是由秒= s0 eKV/2kT.其中s是弛豫时间在一个方向,钾是粒子的各向异性常数, V是粒子量, k为玻尔兹曼常数,和T是温度。任期千伏措施.
能源屏障两方向。随着规模的粒子减少到一定的水平,成为可比千伏的热能KT公司,其启动磁化波动从一个方向到另一个。
因此,在这个Ť的整体磁矩这种粒子是随机零,并颗粒据说是超。
定向,文中主要是指粒子磁化后电磁波的方向。
KV measures the energy barrier between two orientations.这一句,联系上文的“the magnetization orientation of each particle is determined by ..." 是指:KV是用来测量改变粒子的电磁波的方向所须要的能量。
V是粒
