All in all, are derived from the reform and opening up, from the Communist Party policies.

而这一切的一切，都来源于改革开放，来源于共产党的好政策。

Our experiment is unique to clone porcine IL-4 gene from lymphocytes of the local species of Chenghua porcine and systematically study its expressing effect in vivo on the immune system and immune responses of mouse and pig to trivalent vaccines against Swine fever, the Pasteurellosis and Erysipelas suis and pig paratyphoid vaccine.

将得到的序列在GenBank和EMBL数据库中进行了同源比较，结果表明它与来源于长白猪肠粘膜固有层淋巴细胞的白细胞介素-4有99％同源，与来源于杂交猪T细胞的白介素-4有96％同源，说明猪种及组织细胞来源的不同可能使基因有一定的差异。

The competitive advantage in the junior stage is an advantage of the cost, deriving from the incensement in valid demand and supply of high technology products, economy of external scale and external scope, the specializing division of labour on the basis of specialization and the decreasement of transaction cost; but the advantage of the cost is difficult to maintain. The industry cluster competition advantage of the new and high-tach of senior stage is an innovative advantage, stemming from the innovation network of area, which is unable to imitate, existing for a long time.

初级阶段高新技术产业群竞争优势为成本优势，这种优势来源于产品的有效需求与供给增加、外部规模经济、外部范围经济、专业化分工及交易费用的减少，但成本优势难以持久：高级阶段高新技术产业群竞争优势为创新优势，来源于区域创新网络，创新优势无法模拟，可长期存在。

Accordingly,two rules for intent reduction are proposed.If a concept node has only one father concept node,then the intent reduction is formed by the difference sets of its attributes set and its father's attribute set.If a concept has several father concepts,then the intent reduction is formed by two attributes inherited from any two different fathers.

相应地提出了两条内涵缩减的规则：如果一个节点只有一个父节点，那么其内涵缩减来源于它的内涵与父节点内涵的差集；如果一个节点有两个或两个以上的父节点，那么其内涵缩减来源于任意两个父亲节点属性的并集。

In ovary, PNA receptors appeared in the oocyte cytoplasm of second phases of oogenesis; the positive granules gradually increased from third to forth phases, and they exhibit a maximum expression before vitellogennic stage in cytoplasm of oocyte; from vitellogennic stage to chorionation stage, the positive granules gradually reduced. Binding sites on follicle cells were changed with their morphological variation in every stage of oogenesis.The staged and specific expression of oncogene c-kit, the tyrosine-kinase receptor, is closely related with gametogenesis.

2在中华蚱蜢卵子发生的早期，PNA受体是由卵母细胞自身合成；在卵黄发生前的准备时期，卵母细胞质中的PNA受体一部分来源于自身合成，另一部分则来源于滤泡细胞，而糖复合物的大量出现可能直接与卵黄发生有关；卵黄发生期PNA受体的减少可能是在卵黄物质形成中部分发生了修饰；卵黄和卵壳的相继形成过程中，阳性反应的出现说明PNA受体参与了卵黄膜及卵壳的形成，而这些受体物质是由滤泡细胞分泌的。

However, and unlike the Brujah, Gangrel the brave combat lawlessness is not derived from the violent but from their animal instincts.

不过和Brujah不同的是，Gangrel作战时的勇猛不是来源于无法无天的狂暴而是来源于他们的兽性本能。

When a distinction is made between the terms Traducianism and Generationism, the former denotes the materialistic doctrine of the transmission of the soul by the organic process of generation, while the latter applies to the doctrine according to which the soul of the offspring originates from the parental soul in some mysterious way analogous to that in which the organism originates from the parent's organism.

当一个区分条款traducianism和generationism ，前者是指物质主义的传播灵魂，由有机物的过程中产生，而后者则适用于该学说根据其中的灵魂子代来源于父母灵魂，在一些神秘的方式类似，在其中的有机体来源于父母的有机体。

Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。
