轨道的

The criterion for residual deformation of Substructure of unballasted track on railway passenger dedicated line is extremely strict in order to satisfy the safety and comfort requirements of the high-speed train.

中文摘要：为满足高速列车安全、舒适性的需要，保证线路的高平顺性，无碴轨道的铺设与运营对路基、桥涵、隧道等线下结构的工后沉降要求非常严格，追求"零沉降"理念。

The systems can be translated to the systems developed by Wiggins［1 under some conditions.

研究了一类两个自由度系统，利用多重尺度法证明存在锁频于Ω的周期解，在一定条件下可变换为Wiggins的系统［1］，给出了这类系统的同宿轨道的计算公式。

Free amino group and carboxy group on short peptide and amino acid can coordinate metal ion with vacant orbital to form chelate compound.

短肽和氨基酸的自由氨基上的-NH_2、羧基上的-C=O等均可与具空轨道的金属离子产生配位键，形成螯合物。

The light fastness of pyrazolone coupled acid azo dyes has the relationship with 5 independent factors:the NK N2 charge (E-N1 E-N2),the dipole moment,the frontier orbit energy. The equation revealing the relationship was founded.

以吡唑啉酮为偶合组份的偶氮型酸性染料在羊毛纤维上的光牢度主要与下述5个分子结构独立因素有关：N1、N2上的电荷密度（E-N1、E-N2，分子偶极矩（μ，前线轨道的能量Ehomo、Elumo），并建立线性关系式。

That can be compared with theJudging by past experience, a few more pieces of debris will be cataloged in the days to come.

这是值得注意的，速度在轨道的最大差值为22米/秒这可与每几百米的第二次碰撞的典型。

This seems reasonable, for the bases have different HOMO–LUMO gaps, which in principle should lead to different conductivities.

这似乎是合理的，因为基地有不同的HOMO - LUMO轨道的差距，在原则应导致不同的电导率。

Since our last update, we have received numerous tracking measurements of asteroid 2007 WD5 from four different observatories.

在最近的更新中，我们从4个不同的天文台得到了大量的关于小行星2007WD5轨道的数据。

Although the Sahara has been bone-dry for most of its history, it undergoes an approximately 5,000-year humid period every 100,000 years as a result of variations in Earth\'s tilt and the shape of its orbit that change the way sunlight hits the planet.

在其大部分的历史上，尽管撒哈拉沙漠已经变得极为干燥，但是每隔大约5，000年，它都要经历一个湿润期，每100，000年作为地球倾斜变化的结果，它轨道的形状改变了阳光射向这颗行星的路线。

Simulated views of the Moon over one month, demonstrating librations in latitude and longitude.

经天平动是因为地球不在月亮的轨道的中心，而且月亮公转的速度不象自转速度那么均匀等原因导致的。

When N=6, the electron transfer was similar to the case of N = 4, but inner layer electronic local was weakened so that parts of electrons in S layer was excited into P electrons, increasing axial electron mobility, meanwhile more performances of sp2 hybrid orbital formation were completed.

在N=6的图中，电子转移情况类似N=4的情况，但内层电子局域性有所减弱，导致部分s电子被激发成p电子，增大轴向电子流动性，同时可表现更多的sp2杂化轨道的形成。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
