Acidic rocks have a silica content over 70 % Granite is the typical example of acidic intrusive igneous rock, which is composed mostly of potash feldspar, quartz and minor mica.

岩石中Si02含量大于70%时，称为酸性岩，花岗岩就是酸性侵入岩石的一个典型例子，它的矿物成分主要是钾长石、石英以及少量云母

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓～S～D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。

In contrast, many geological, petrological and geochemical problems of H9 formation remain unsolved.

文中详细论述了这些火山岩石的结构构造、矿物成分和岩石化学成分，以及微量元素。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
