本文以包含不连续变化因素的电力价格为对象，系统研究跳跃扩散过程下的实物期权决策理论，从理论和现实关系考察不连续变化因素对诱发投资最优时刻触发价值的影响，尝试在结合市场条件动态变化及投资者投资行为的基础上对传统实物期权理论进行扩展，最后分析了实物期权的数值计算方法。

At present, the research about Heregulin-αand itsreceptors ErbB2 and ErbB3 was only the expression of them in mRNA and the impact ofHeregulin-αon the proliferation of mammary epithelial cells and milk proteins expression inculture. There were no results about the expression of Heregulin-αand its receptors in protein andthe impacts of Heregulin-αon the development, lactation and involution of mammary gland. It wasalso not clear about the signal transduction pathway of Heregulin-αin mammary gland.

目前对于乳腺中Heregulin-α及其受体ErbB2和ErbB3的研究仅限于其mRNA水平的表达以及Heregulin-α对培养的乳腺上皮细胞增殖和乳蛋白表达的影响，尚缺乏对乳腺中Heregulin-α及其受体在蛋白质水平上的表达变化规律以及Heregulin-α对乳腺发育、泌乳及退化的作用研究，正常乳腺中Heregulin-α的信号转导途径也不完全清楚。

Using this model, we analyze the impacts of the channel on time variation characteristics within a transmission block which destroy the orthogonality of subcarrier and cause serious intercarrier interference.

We reviewed the parameters relating to clonal growth, such as internodal length, spacer length and branching angle as well as rhizome elongation and branching rates, of seagrass species. These parameters have determinant impacts on the expanding of seagrass patches. However, breeding system may also affect patch sizes.

与克隆生长有关的参数(如节间长度、间隔子长度、分枝角度以及延伸速率和分枝率等)对于海草的克隆生长有着决定性影响，但繁育系统对克隆斑块大小也有较大影响。

Characteristics of Inclusions: After the tea is kept for a long period of time in a stall and deep fermentation processing begins, the specialties of material and manufacturing make many bioreactions occur for thorough activation of microbes to excrete extra-cellular enzymes, which impacts over 500 stuffs of tea. Theses microbes contain catechin, polyphenols, amylase, cellulose, protein, lipid ,alcohol, ketone, vitamin, microorganism, and organic acid, making them transform, isomerize and degrade, polymerize and couple, so as to produce amylase, thearubigins, theaflavins, cellulose, and microelements that other commercial teas could not produce or produce too little.

三、 内含物的特点：由于原料、制造的特别性，经长期陈化和深发酵的过程，茶叶内含物发生多种生物生化反应，充分激活微生物分泌胞外酶，作用于茶叶中的内含儿茶素、多酚、多糖、纤维素、植物素、蛋白质、脂类、醇类、酮类、维生素、微量元素、有机酸等500多种物质，使之转化、异构降解聚合耦联，生成其他商品茶无法比拟和缺乏的多糖、茶红素、茶黄素、纤维素、微量元素等，并形成以菇稀醇类为主体香气。
