钙长石的

Dark colored, fine-grained, and composed primarily of the feldspar mineral Calcic Plagioclase and the amphibole mineral Pyroxene.

深色，细粒度，主要组成为长石矿物类的钙斜长石和闪石矿物类的辉石。

Actually, the term feldspar refers to a group of closely related minerals which have generally similar composition and characteristics.

严格地说，长石这个名称指的是成分和特征大体相似的一组有密切关系的矿物，它们是钠、钾、钙的铝硅酸盐类。

The garnets in the granitic gneisses from southern Dabie mountain were characterized by riching in Fe and Mn, and pooring in Mg, differing from the garnets in the UHP gneiss and eclogite, which relatively riching Mg. But the plagioclase in the granitic gneisses from the northern Dabie mountain was relative high Ca contenents, their An is 25.2-27.9, within the oligoclase field.

石榴石总体以贫Mg富Fe和富Mn为特征，明显不同于榴辉岩及高压片麻岩中石榴石相对富Mg的情况；而北大别英云闪长质片麻岩中斜长石的钙含量相对较高，An为25.2-27.9，位于奥长石范围内，角闪石中Mg的含量较高，具有壳幔混合源的特征。

Any of a group of abundant rock-forming minerals occurring principally in igneous , plutonic, and some metamorphic rocks, and consisting of silicates of aluminum with potassium, sodium, calcium, and, rarely, barium.

"任何一组由大量岩石形成的矿物，主要存在于火成岩、深成岩以及一些变性的岩石中，含有钾、钠、钙及极少的钠的铝硅酸盐，地球的外层地壳中约百分之六十是长石。"

The results show that the mineral compositions of feicui is more complex. Its main mineral is jade, and the other minerals are aegirine vryite and so on.

研究结果表明，翡翠的矿物组成比较复杂，主要矿物为硬玉，其次有霓石、透辉石、钙铁辉石、钠铬辉石和钠长石，还有少量绿泥石，铬铁矿，褐铁矿和赤铁矿等。

Synthetic ettringite precipitated from solution shows a highly positive zeta potential, hence it adsorbs great amount of negatively charged superplasticizer. Monosulfate has only a slightly positive zeta potential and adsorbs smaller amounts of superplasticizer. For syngenite, portlandite and gypsum, the zeta potential is around zero or negative.

以溶液沉淀析出法人工合成的AF具有较高的正zeta电位，能吸附大量带负电荷的超塑化剂，AF仅带少量正电荷，其吸附超塑化剂相对较少，钾长石、氮氧钙石和石青的zeta电位几乎为零或负值，因而基本不吸附超塑化剂。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
