The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.
由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

We also simulate the environment of photon experiment, and calculate the effect by use of fourfold symmetry torsion pendulum, we find that the double frequency effect caused by gravitational gradient is reduced a magnitude when we buildup the symmetry of measurement system.
我们还对二重对称扭秤的光子实验数据进行了分析，结果发现二倍频的效应为10~(-12)Nm 的量级，通过计算分析我们发现扭秤周围环境的不对称所引入的引力梯度效应是不容忽视的，因此针对喻家山人防山洞的具体情况，我们对光子实验的实际环境进行了模拟计算，理论分析结果表明对于二重对称的扭秤而言，环境不对称的影响引起的力矩效应为5.4940×10~(-10) Nm，对于四重对称的扭秤来说，效应为1.8668×10~(-11)Nm，可以看到随着扭秤对称性的增加，引力梯度的效应减小了一个数量级。
