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 boundary value problem for first-order differential equations with a parameter refers to the finite solution condition of equation which includes unknown quantity and its first-order derivative that not only relies on interval value but also relies on the parameter of the equation,which is always settled by fixed point theory or successive approximation method.

含一个参数的一阶微分方程边值问题是指：含有未知量及它的一阶导数的方程的定解条件不仅依赖于在区间端点的取值，而且依赖于方程中的参数。通常它用不动点定理或逐步逼近法来解决。

Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。
