By choosing to observe stars that are known as Cepheid Variables he could more accurately make measurements.

通过有选择地观察恒星被称为cepheid变数，他能更准确地进行测量。

This was accomplished by observing Cepheid variables at optical wavelengths out to greater distances than obtained previously and comparing those to similar measurements from ground-based telescopes.

这是通过观测比先前远得多的造父变星的可见光谱实现的，结果与地面望远镜观测结论类似。

Wendy freedman of the carnegie observatories in pasadena, california, and her colleagues used the space telescope to examine the spiral galaxy m100, in which they discovered cepheid variables.

加州帕萨迪那卡内基天文台的温迪弗里德曼和她的同事们使用空间望远镜来观察螺旋状星系m100，并在其中发现了造父变星。

Hubble observations of pulsating stars called Cepheid variables in a nearby cosmic mile marker, the galaxy NGC 4258, and in the host galaxies of recent supernovae, directly link these distance indicators.

哈勃望远镜观测了一个近距离的星系NGC 4258中一类被称为造父变星的脉动变星和当前的超新星，直接比对了这些距离指示器。

The current directory at execution time is also different (it is usually the server's cgi-bin directory) and the set of environment variables is also different from what you get when you log in.

当前的文件夹在执行时间时也是不同的（它通常地是服务器的 cgi-bin 文件夹）并且环境变量的设置与当你登录时获取的也是不同。

Two variables are said to be correlated if a changed in the value of one variable is accompanied by change in the value of anther variable.

有两个变量，如果一个变量值变化而导致另外一个变量值也变化，则称这两个变量相关。

In the dissertation, a new corrected method, straightened algorithm, is presented, with the help of the algorithm, not only the characteristic of sparsely strip matrix be can assured, but also the complicated extent of calculation be can greatly reduced because the variables that locate only in the strip matrix are optimized.

而本文提出了一种新的修正方法—拉直算法，该方法不仅能够保证修正后系统模型的矩阵仍然保持带状稀松的特点，而且由于只对在系统矩阵的带状部分进行优化，其计算的复杂程度也简化了许多。

The deployment of technical characteristic target value is a complicated process with multiple variables and multiple objectives.

技术特征目标值的配置是一个复杂的多变量、多目标决策过程。

I. d. Bernoulli random variables. First, we can get the upper bound with order from Chebyshev inequality. Second, a better upper bound was gotten with the new inequalities, which can fasten the convergence rate.

并对服从两点分布的独立随机变量X1，X2，…，X进行研究，首先利用Chebyshev不等式得到随机变量偏离方差ES的上界，但它只有阶的收敛速度，然后利用新的不等式得到一个新的上界，它有更快的收敛速度，这在探讨收敛速度时有着重要的理论意义。

The father that if work,mad father, love annoys, disposition is too indrawn the be short ofing that the father of Mu Ne, resign oneself to adversity causes father easily to love is broken; Communicate time effectively between father and son, Mu Zizhi to be less than a hour on average to wait a moment every week, it is the cause that causes the child to become addiction.

如工作狂的父亲、爱愤怒的父亲、性格过于内向木讷、逆来顺受的父亲都易造成父爱的缺失；父子、母子之间的有效沟通时间每周平均小于一小时等等，都是造成孩子成瘾的原因。

These are vandal proof and they come with a locking mechanism.

这是野蛮的证据，他们来到了锁机制。
