硅周期系第 IV 类元素，是非金属元素，原子序数14，原子量为28.80；密度为2.33g /m3；熔点为1410℃；沸点为2355℃；电阻率为2140Ω。m ；有无定型和晶体两种同素异形体。

The elements, if arranged according to their atomic mass, exhibit an evident periodicity of properties.

元素，如果按照他们的原子质量来安排，则它展示了一个明显的周期特性。

Science has laid down the principle that the properties of an element are a periodic function of its atomic weight.

科学发现了这样一条规律："元素的性质是原子重量的周期函数。"

In this paper, we give the upper bounds for inverse elements of strictly diagonally dominant periodic tridiagonal matrices.

本文给出了严格对角占优的周期三角矩阵逆元素的上界估计。

There is no remaining chi between cycles in the Tao; and so anything remaining would go extinct or in other terms falls into disanimation.

在道的2个周期间隔之间是没有 chi （译注：发音为"气"，为了避免和四大元素中的气所混淆，故而在此保留原文）存留下来的，因此任何留下来的事物将会进入绝灭，或者换句话说，跌入死亡。

The series of Memory Phonograph—A Chronicle Collage of Old Family Pictures and Images uses the images and genealogy on the family album as elements of creativity, studies life cycle of human beings and the pursue of values of life. By means of tracing back to the root of the family and going all the way down the reflections of self existence, the creator attains self-discovery in life and finds therapy through art.

记忆留声机—家族老照片图像拼贴日记」系列，藉由家族相簿上的图像以及留下的族谱，作为创作的元素，探讨人类生命物体的周期，对生命价值的探求；上推家族根源的追寻，下至个人自我存在的省思，也是创作者自身对生命的探索与治疗。

According to the problem of the long processing time and testing cycle for food measurement, the feasibility of using one microwave digestion solution to investigate seven elements in food was discussed.

摘 要：针对食品检测前处理时间和检测周期过长的难题，用硝酸及双氧水作为消解溶剂，在设定的微波消解条件下，可以将样品消解完全，消解液中加入硫脲和L盐酸，不需任何处理可直接进行砷等7种元素的测定。

The second element in the periodic table, a lighter than air, inert gas often used to fill balloons.

在周期的桌子中的第二种元素，一个点火者超过空气，惰性的瓦斯时常过去一直填充气球。

Using the estimates of character sums over Galois rings and the trace de scription of primitive sequences over Zpe, we obtain an estimate for the frequency of the occurrences of any element in Zpe in one period of a primitive sequence, which is better than Kuzmin's results[1] if n ＞ 4e, where n is the degree of the generating polynomial of the primitive sequence.

范淑琴 ，韩文报文研究了Zpe上本原序列的元素分布。利用Ga，lois环上的指数和估计和本原序列的迹表示，得到了Zpe中各元素在本原序列的一个周期中出现频率的一个估计。当n＞4e时(n为本原序列生成多项式的次数)。我们的估计优于Kuzmin的结果[1]。

According to the Aufoau build-up principle and the order of filling atomic orbits, the valence electron configuration of ground state atoms of the d-block transition elements seems only to be (n - 1 ) dx-2 us2x here denotes the number of the electron in (n - 1 d and us orbits.

众所周知，元素周期系过渡元素基态原子价电子组态的多样化是已往的原子构造理论无论是从定性还是从定量方面都是迄今难以给出圆满理论解释的原子构造现象之一［1～11］。
