查询词典 a trace

You can trace the outlines of such patterns, you know how to move your head to get a better view, and you know when you have moved it too far to see the whole keyboard. You can obscure any feature of the keyboard by holding your finger at an appropriate location between it and your eye. And instead of describing the relation between the Intel logo and the 'P' key, you can use your finger to trace a connecting path.

你能循迹这样的样式，知道如何移动你的头获得更好的视角，你知道当你移动足够员能够看到全部键盘的时候，你能在它和你的眼睛之间，用手指分不清任何键盘的特征，取代在'图标'和'P键'之间关系的描述，你能用你的手指循迹一个相关路径。

The idea that experience leaves some trace in the brain goes back at least to Plato's Theaetetus metaphor of a stamp on wax, and in 1904 the German scholar Richard Semon gave that ghostly trace a name: the engram.

其实，有关体验会给大脑留下某些痕迹的想法，最早可以追溯到柏拉图有关蜡上印记的比喻中，而到了1904年，德国学者塞蒙把这种精神性的痕迹命名为：记忆印迹。

The representation of sequences is very helpful for the research of their linear complexity,so this paper we first research trace representation of periodic sequences,and the trace representation of a New Generalized Cyclotomic Sequence of order two of length pq is given,then for 2~mp~n period binary sequences,where p is an odd prime and 2 is a primitive root modulo p~2,we present a relation-ship between the linear complexity and the minimum value k for which the k-error linear complexity is strictly less than the linear complexity and have the upper bound and lower bound of the value k, finally we discuss the k-error linear complexity of legendre sequences,also have the upper bound and lower bound of the value k,and discusses the situation where the linear complexity drop again for some Legendre sequences.

序列的表达形式对于其线性复杂度的研究是十分有帮助的，本文我们首先研究的是周期序列的迹表示，给出了2阶pq长度的扩展分圆序列的迹表示，然后讨论了周期为2~mp~n(m≥2)序列的线性复杂度与使得线性复杂度变小的最小的k值的关系，给出了k值的上界和下界，这里p为奇素数，2是模p~2的本原根，并通过例子讨论了其线性复杂度的稳定性，最后对Legendre序列k-错线性复杂度进行了分析，也给出了k值的上界和下界，并对某些Legendre序列讨论了线性复杂度再次下降的情况。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.
