In this paper the reason of rapid increase of single phase short circuit current in 500 kV substation is analyzed. Through the calculation it is proved that neutral grounding by small reactance is an effective measure to reduce the single phase short circuit current, and the calculation method of the zero\|sequence reactance after autotransformer neutral grounding by small reactance being applied is expounded.

文中研究了500kV变电站单相短路电流急剧增长的原因，计算了变压器中性点经小电抗接地对限制单相短路电流的作用，论证了经小电抗接地是限制单相短路电流的有效措施之一，并阐述了500kV自耦变压器中性点经小电抗接地后，其等值零序电抗的计算方法，可供工程参考。

In this dissertation, GPS baseline solution precision is analyzed since the following aspects: 1, Different length baselines are processed and analyzed by single frequency model and ionosphere free model. 2, Basing on current single point positioning precision, certain coordinate error is added into fixed points to study the result. 3, Baseline is processed and analyzed with different observation vectors and their lineal combination models. 4, 24 hours observation was divide up to process baseline.

本文从以下几个角度研究了影响GPS基线解算精度的因素：1、采用单频和消电离层模式对不同长度的基线分别解算，对处理结果进行分析。2、根据目前单点定位精度给起始点加上适当的坐标偏差，研究起始点坐标偏差对基线处理结果的影响。3、选用不同的观测值及其线性组合，对基线解算结果进行研究。4、对24小时观测的数据分时段处理，分析观测时间段对基线处理结果的影响。

In recent years,the increase of single nation are attracting people's notice.Some of them aspired after undertaking,so that they are no marriage on the agenda.Some people may be so engrossed in work, entertainment, travel and make friends,anyhow,the reason of keeping single is not the same.More than 80% of them did not abandon the traditional marriage values,and expressed hope to marriage or one day be married.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
