The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。

This dissertation interprets Marx"s thought of leisure in terms of value philosophy, which is based on Marx"s stipulating value intension of leisure: First, leisure is a kind of living pattern as well as a value ideal, it is a value goal pursuing dynamic development that is realized constantly during the practical experience of life of people; Second, leisure is not only a question of free-time, but also persons value orientation.

本文选择从价值哲学的角度来解读马克思的休闲思想，正是基于马克思对休闲的价值内涵的规定：第一，休闲既是一种生活方式，又是一种价值理想，是人们在生活实践中不断追求实现的动态发展的价值目标；第二，休闲不仅仅是自由时间的问题，而且是个人的价值取向问题。

Different point basically is reflected in:(1) is on philosophical foundation, former it is guidance with Marxism philosophy, latter is directive;(2) to be on the purpose of research and jumping-off place with subjective idealism and metaphysics, former it is to be surplus value theory to lay a foundation, supply thought weapon for proletarian revolution, latter is to be bourgeois to serve;(3) to be on value source, former position works alive is the only fountainhead of value, latter thinks effectiveness or the fountainhead;(4) that effectiveness rate is value finally are on value Standard Dimension however, former consider as socially necessary labor time, latter considers as limit effectiveness to wait a moment.

不同之处主要体现在：(1)在哲学基础上，前者以马克思主义哲学为指导，后者以主观唯心主义和形而上学为指导；(2)在研究的目的和出发点上，前者是为剩余价值理论奠定基础，为无产阶级革命提供思想武器，后者则是为资产阶级服务；(3)在价值源泉上，前者主张活劳动是价值的惟一源泉，后者却认为效用或最后效用程度是价值的源泉；(4)在价值度量标准上，前者认为是社会必要劳动时间，后者认为是边际效用等等。

this gets sick the clinical symptom not to have the characteristic value, the medical history has the reference value.the sphere focus of infection has the crecent moon in the phantom performance to draft, the air bronchial tube drafts, the corona drafts to this sickness has the prompt value, sends the tubercle to see the small empty shade to have the diagnosis value, if in the discovery meniscus cavity has along with the body posture change "in the hole the ball drafts", has the important diagnosis value to the lung aspergillomycosis.this gets sick the diagnosis needs the pathology and the bacteriology inspection.

本病临床症状无特征性，病史有参考价值。在影像表现上球形病灶有新月征、空气支气管征、晕征对本病有提示价值，多发小结节均见小空洞影有诊断价值，如发现半月形空洞内有随体位改变的&洞中球征&，对肺曲菌病有重要诊断价值。本病的确诊需病理和细菌学检查。

The sixth part: Studies on the dynamic changes of soil retention function value of ecosystem in YUYANG District. Utilized ERDAS8. 5 to interpret the remote sensing image and get LUCC data and vegetation information of YUYANG District. Utilized R2V5. 5 to digitize administrative map, topographic map, vegetation picture, soil distribution map and meteorological website map. Utilized ARCINFOR8. 3 to change every digitization layer to the same projection, to generate Tyson polygon, to structure DEM and do vector polygon overlay. Utilized ARC VIE W3. 3 to obtain the grid data topographic slope and slope length from DEM data of YUYANG District, and then, turned every coverage layer into grid layer and do grid polygon overlay to gain data about dynamic changes of value of soil retention of ecosystem in YUYANG District, at last, the author analyzed the features of the spatial-temporal changes and its reason.The seventh part: Studies on the dynamic changes of fixing drifting sand against wind function value of ecosystem in YUYANG District.
