The author analyzed the current state of the declining performance of Chinese athletes in traditionally advantageous track and field events, and considered that the backup talents for traditionally advantageous track and field events was short of supply for the following reasons: The serious difficult-job dodging ideology of local sports management leaders and the existing competition system have restricted the opportunity for current excellent athletes to temper themselves; blind training ideology existed in the training conception for traditionally advantageous track and field events; the coaching performance of coaches for traditionally advantageous track and field events was kind of poor.

摘 要：对我国田径传统优势项目下滑的现状进行了分析，认为原因在于田径传统优势项目后备人才乏人、地方体育管理决策层避重就轻思想严重、现行的竞赛制度减少了现役优秀运动员参加大赛磨练的机会、田径传统优势项目训练存在闭门造车现象、田径传统优势项目教练员执教水平的局限等。

Have a lot of advantage , former predestined relationship of Huizhou City advantage , Huizhou City is located in peart triangle Northeast , adjacent HongKong , fields such as Shenzhen , Dongguan , geographic location are very advantageous;Secondly , Huizhou City is a minimal city of pearl triangle population density , both land resources and water resource enrich comparatively;Huizhou City already forms the body traffic network being composed of deepwater port , express highway , Beijing-Jiulong Raiway , airport etc.once again , at present , logistics advantage is very obvious;Now available Huizhou City electronic information estate , petroleum and chemical estate etc.develops vigorously finally , supporting advantage having already formed fairly good estate.

惠州有许多优势，先是地缘优势，惠州地处一反常态一角东北部，毗邻香港、深圳、东莞等地，地理位置十分优越；其次，惠州是珠三角人口密度最不的城市，土地资源和水资源都比较丰富；再次，目前惠州市已形成由深水港、高速公路、京九铁路、航空港等构成的立体交通网络，物流优势很明显；最后，惠州现有的电子信息产业、石化产业等蓬勃发展，已经形成了较好的产业配套优势。

The second part explains the classical comparative advantage theoryand competitive advantage theory on international trade which includes: Adam Smith's theory of absolute interests、 David Ricardo's comparative advantage theory、 the Theory of natural resources gift raised by Hekexieer and Elian , Leontief Paradox and competitive advantage theory (based on the industrial perspective, the resource base perspective, the dynamic capacity perspective), so as to provide a theoretical basis cement engineering services for the analysis of international enterprises.

第二部分，对有关国际贸易的古典比较优势理论和竞争优势理论进行了阐述，主要理论包括：亚当·斯密的绝对利益理论、大卫·李嘉图的比较优势理论、赫克歇尔和俄林的资源禀赋理论、里昂惕夫悖论以及竞争优势理论（基于产业组织视角、资源基础视角、动态能力视角）等，从而为水泥工程服务企业国际化分析研究提供理论基础。

Walchia ewingi Fuller（66.2%）, Laelaps turkestanicus Lange（38.5%）, Paradoxopsyllus custodies Jordan（42.9%）and Hoplopleura pacifica （80.1%）were the most predominant species of chigger mites, gamasid mites, fleas, and sucking lice, respectively.

攸氏无前恙螨为优势恙螨种，占恙螨总数的66.2%(710/1 072)；土尔克厉螨为优势革螨种，占革螨总数的38.5%（396/1 029）；绒鼠怪蚤为优势蚤种，占蚤总数的42.9%（9/21）；太平洋甲胁虱为优势吸虱种，占吸虱总数的80.1%（217/271）。

The results showed that Liquidamba formosana, Quercus acutissima, and Quercus fabri populations had the dominant positions in the forest community of Purple Mountain Area of Nanjing. During the growth process, the mortality of L. formosana, Q. acutissima, and Q. fabri were higher in low age. After entering into the middle-age stage, the upper space was occupied by oak and L. formosana population all died. The mortality of Q. acutissima and Q. fabri populations were increased with the increasing of diameter class. L. formosana population in the Purple Mountain Area of Nanjing belonged to be the typical growing population and Q. acutissima population was a decreasing population. Q. fabri population belonged to be the growing population on the whole, but the diameter class in middle parts was incomplete and the population was difficult to be renewed. Among the studied quadrate, only one dominant population showed an aggregated distribution and other dominant species showed the random distribution. Either, all the dominant species in all the quadrates presented random distribution.

结果表明，枫香种群、麻栎种群和白栎种群在南京紫金山地区森林群落中占有优势地位；枫香种群、麻栎种群和白栎种群在其生长过程中，在低龄时期，死亡率都较高，进入中龄期后，由于上层空间都被栎木占据，枫香种群全部死亡，而麻栎种群和白栎种群的死亡率则随着径级的增大而增大；南京紫金山地区枫香种群属于典型的增长型种群，麻栎种群属于衰退型种群，白栎种群总体上属于增长型群落，但中间径级不完整，种群更新较为困难；在所研究的每一个样方中，一般只有一个优势物种呈聚集分布，而其他优势物种呈随机分布，或样方中所有优势物种都呈随机分布。

The shared resource not only has significant positive impact on the competitive advantages of the firm in the cluster, but also has indirect negative impact on the competitive advantages of firms in cluster. The mechanism of the shared resource acting on the competitive advantages of the firm in the cluster is complicated.4 The rigidity of shared resource can be reified to different kinds of rigidities, and different kinds of rigidities have different modes of effecting on the competitive advantages of firms in cluster.

共享性资源对集群企业竞争优势不仅具有正向作用，还可以通过共享性资源刚性对集群企业竞争优势产生负向作用，因此，集群企业竞争优势水平是共享性资源对其多种路径共同作用的结果；(4)共享性资源刚性可以分解出各种不同类别的具体刚性要素，不同的刚性要素对集群企业竞争优势产生作用的路径不同。

The important values of shrubberies dominant trees were very higher than that of the sub-dominant trees, which showed that the dominating trees had obvious role in keeping community\'s structure and ecological function.

灌木层片优势物种的重要值非常突出，远远大于群落亚优势物种，这表明在维持群落结构与生态功能方面优势种具有突出作用。
