It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

Results: Caspase-3 mRNA was constitutively expressed at a low level in freshlyisolated CD34+ cells. The expression of caspase-3 mRNA and protein was upregulated when these cellswere first expanded in suspension culture with growth factors for 3 days. However, only the 32 kDa inactivecaspase-3 proenzyme was detected in the freshly isolated CD34+ cells as well as during the first 3 daysexpansion with cytokines.

检测结果显示，Caspase-3mRNA在新鲜分离的脐血CD34+细胞中低水平表达，在细胞因子支持下体外培养3天，扩增的CD34+细胞中Caspase-3mRNA和蛋白质水平表达上调，但在这两种细胞中仅能检测到分子量为32KDa的非活性酶原形式的Caspase-3；随着体外培养时间的延长，在IL-3，IL-6和GM-CSF组合条件下，Caspase-3被激活，可检测到分子量为20KDa的裂解片段。

In the differentiation of pteridophyte ecophenotypes, VA mycotrophy was maintained in the terricolous plants as an adaptive strategy, but it was abolished in the epiphytic plants

在蕨类植物的生态类型分化过程中，VA菌根营养作为一种适应对策，在土生植物中被保留下来，而附生植物则拚弃了这种适应对策

In contrast, individual plate are considered a "Hard Trading in a Dream," which may be a marketing tactic is that some developers might take into account the future real estate development cycle variable length, in the renewal period will have a market gap in the emergence of standby to intervene in the market in order to obtain a better price space.

与此相反，个别板被认为是"硬贸易在梦中，"这可能是一种营销策略是，一些开发商可能会考虑到未来的房地产开发周期变长，在延长期内将有一个市场中的空白出现待命干预市场，以获得更好的价格空间。

Neural network has been widely used in nonlinear control systems in many fields as a novel method or measure. However, there are very few published studies dealing in neural network used in control of the locomotive and rolling stock.

神经网络作为一种新的方法和手段，已被广泛地应用于非线性系统的控制中，但在机车车辆的控制中的应用少有报道。

Argentina is Salta and the culture shock of finding myself in a seemingly European city, the desert to Mendoza, delicious wine, huge steaks, the massive barrier of the Andes, the extraordinary clarity of light in Patagonia and, in driving sleet, surprise at startling a flock of green parrots from trees along a river bank.

阿根廷给我印象深刻的是萨尔塔，在这里我经受到一种"文化冲击"，好像自己到了一个欧洲城市。还有门多萨的沙漠、美酒、大块的牛排；安第斯山巨大的屏障，帕塔格尼亚异常清澈的阳光。在冷雨霏霏中行驶，很惊奇地看到一群绿色的鹦鹉从沿河岸的丛林中被惊飞。

Cluster sampling: When the basic sampling unit in the population is to be found in groups or cluster s the sampling is sometimes carried out by selecting a sample of cluster s and observing all the members of each selected cluster .

整群抽样：一种抽样方法。当母体中的基本抽样单位是按群、组分类时，有时抽样方式是选择一类样本群组，然后对被选择的群组中的每一个样本单位的全体成员进行观察。

In a word, this two chapters, focusing on the analysis of two women characters, especially Sula, the heroine, depict three different kinds of black women: Eva, the ancestor of self-searching, passive and assimilated by the male-centered consciousness in the end; Sula, a new world woman, completely independent in self-searching and Nel, the future successor to Sula in the pursuit of self and thus show Morrison"s profound recognition of the hard process of black women"s self-searching.

总之，这两章通过对小说中两个主要人物，特别是通过对女主人公秀拉的分析，展示了三种不同的女性形象：被动探寻自我并最终被男性意识同化的的老一辈人物伊娃，完全独立追寻自我的新时代女性秀拉以及未来追寻自我的秀拉的继任者内儿，从而强调了黑人女性追寻自我历程中的艰难。

There are several different types of sample surveys: Simple random sampling: every member of the target population is equally likely to be selected, and the selection of a particular member of the target popula- tion has no effect on the other selections.

有以下几种抽样统计：简单随机抽样：不同目标人群中的每位成员具有相同的被抽取几率，抽取目标人群中的任意成员对其他成员的抽取没有影响。
