They are always characterized by concentric zoning texture, from the rim inward, consisting ofepidote, allanite and apatite; micro-inclusions of thorite are found within both apatite and allanite.

它们以同心环带结构为特征，从边部向中心依次为绿帘石、褐帘石和磷灰石；钍石既可包裹再磷灰石中，也可见于褐帘石中。

Major conclutions from this study can be summarized as following:1. On mineralogy, rutiles, apatites, epidotes and vein minerals from UHPM rocks were firstly and systematically studied, by detailed petrography and mineral-chemistry investigation, some mineral or mineral assemblage with special composions or texture were firstly found in UHPM rocks from Sulu-Dabie, for example, corrudum, magnesite, high-Ti biotite and garnet were found as inclusions in rutiles from eclogites, Nb-Fe rutile and zoned Si-Y apatite were found in gneiss, epidote / allanite with euhedral zones like magmatic genesis were found in elogites and gneiss, a lot of minerals with high REE, HFSE, LILE and volatiles were found in veins of gneiss.

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。

The ophitic and subophitic textures, elongated apatite crystals, low Al(superscript Ⅵ)/Al(superscript Ⅳ) ratios (0.00-0.28, 0.12 on average) in clinopyroxene, and low Cao content in olivine (0.04%~0.24%, average 0.12%) indicate that the gabbrowas crystallized at a low pressure.

辉长岩所具有的辉绿辉长结构、大量细长针状磷灰石、单斜辉石中较低的Al/Al值（0.00~0.28，平均为0.12）及橄榄石中较低的CaO含量（0.04%~0.24%，平均为0.12%），均体现出浅成侵入岩的特点。

The ophitic and subophitic textures, elongated apatite crystals, low AlⅥ/AlⅣ ratios (0.00 ～0.28, 0.12 on average) in clinopyroxene, and low CaO content in olivine (0.04%～0.24%, average 0.12%) indicate that the gabbro was crystallized at a low pressure.

辉长岩所具有的辉绿辉长结构、大量细长针状磷灰石、单斜辉石中较低的AlⅥ/AlⅣ（0.00 ～0.28，平均为0.12）及橄榄石中较低的CaO含量（0.04%～0.24%，平均为0.12%），均体现出浅成侵入岩的特点。

The name Apatite comes from the Greek word "apatao", meaning "to deceive", as Apatite has often been confused with gems such as Paraiba Tourmaline, Peridot and Beryl.

磷灰石英文名来源于希腊语&apatao&，意思是&将您愚弄&，因为人们常常分不清磷灰石与帕拉依巴电气石、橄榄石和绿柱石等宝石的区别。

In the detrital zircon sample FH4, which was collected from lower sandstones of the Fanghushan Formation, the oldest sedimentary strata of the Hefei Basin. HP-UHP mineral inclusions such as coesite, omphacite, phengite and melt inclusions, and other minerals like apatite, quartz, feldspar, white micas were identified by means of micro-laser Raman spectrometer and electron probe.

防虎山组的下部砂岩地层是合肥盆地最古老的中生代沉积地层，在样品FH4中选出了碎屑锆石，通过显微激光拉曼光谱、电子探针的研究发现，锆石中含有柯石英、绿辉石、多硅白云母等典型的高压－超高压矿物包裹体、熔体玻璃包裹体以及磷灰石、石英、斜长石、白云母等矿物包裹体。

It comes in many colors, including green, yellow, blue, violet, and a yellow-green variety, originally mined in Spain , commonly called "Asparagus Stone" because of its similarity in color to the vegetable.

磷灰石颜色繁多，有绿、黄、蓝、紫罗蓝等颜色。源产于西班牙的一种黄绿品种胜似蔬菜的颜色，人们通常称之为&黄绿磷灰石&。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
