条纹长石

The study shows that almost all the feldspar in the alkali-granite is perthite, the host-crystal is microcline, the chadcrystal could be either albiter or oligoclase. The Alkali-amphibole is either manganese-magnesia-arfvedsonite or arfvedsonite, and all the alkali-pyroxene is aegirine.

结果表明，该区富碱花岗岩几乎所有的长石均为条纹长石，主晶为微斜长石或高微斜长石，客晶为钠长石或更长石，碱性角闪石为含锰镁质钠铁闪石或钠闪石，碱性辉石均为霓石。

The feldspar in A-type granite is perthite, the dark alkali-minerals in which are arfvedsonite or manganese-bearing magnesia- arfvedsoniteand aegirine.

碱性花岗岩中的长石为条纹长石，暗色矿物为钠铁门石或含锰镁质钠铁门石及霓石。

Microperthite is known to occur in the uppermost 1,000 feet of the Upper Zone, but the amount is small.

微条纹长石见于上岩带顶部的1000尺范围内，但含量不多。

Because the surface of exsolution lamellar is not absolutely smooth, iridescence always looks like contour line of map. Additionally, the thickness of exsolution lamellar is related to calcic content, the more the calcic content, and the thicker the lamellar, the longer the wavelength of interference color.

出溶结构层有其特殊的取向，由于结构层的取向在某种程度上取决于条纹的成分，因而不同产地和结晶环境的拉长石，尽管晕彩色相同，其出溶条纹中的钙含量和条纹的具体取向也不尽相同。

Two lithological groups, the northern marginal facies and the main body, were distinguished within the Tasigake alkali granite pluton of Ulungur in northern Xinjiang, China.

但是 ，与同位素组成演化了的长路径大气降水在相对较长的时限内的相互作用，导致了主体相样品的较缓的斜率以及石英和条纹长石的较高程度的 1 8O亏损。

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。
