中文摘要：本文采用多组态相互作用方法和Rayleigh-Ritz变分法，以类锂等电子系列为研究对象，重点研究了(Z=2)He-的亲和能和束缚能，氦负离子是最简单的类锂离子，我们首先计算了氦负离子1s2s2p~4Po的能量，然后又计算了氦原子1s2s~3S的能量，由此可以得到氦负离子的亲和能。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

雅山晚阶段黄玉锂云母花岗岩的长石矿物是富磷长石，磷以PAlSi〓替换方式进入长石结构中，并且在长石中的分布很不均一，一般是晚结晶的长石比早结晶的长石的磷含量高，同期结晶的钠长石比钾长石的磷含量高；锆石矿物为高度富铪、铀、磷和铝的锆石，磷主要以(Y， HREE， Fe)〓P〓〓〓Si〓〓、Al〓P〓Si〓〓、P〓Al〓Si〓〓Zr〓〓等替换方式进入锆石晶格中，富磷锆石是岩浆高度演化的结果，是高磷花岗岩的特征矿物之一；雅山含有丰富的磷锂铝石，是高磷花岗岩的主要磷酸盐矿物；铌—钽矿物主要有铌锰矿—钽锰矿、锡锰钽矿—钛锰钽矿、细晶石等。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
