The meaning of calorific value measurement is presented and how to develop software of system of calorific value measurement with VB is discussed.

阐述了煤的发热量测量的意义，介绍了用VB开发热值测量系统软件的思路和实现

Although the total calorific value of oxypropane flame is higher than that of oxyacetylene flame, its first calorific value is lower,so its burning temperature is lower and its heating time is longer.

氧丙烷焰比氧乙炔焰的总热值高，但一次热值低，因此燃烧温度低，预热时间较长。

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。

有高热值(higher calorific value)和低热值(lower calorific value) 两种. 前者是燃料的燃烧热和水蒸气的冷凝热的总数,即燃料完全燃料时所放出的总热量. 后者仅是燃料的燃烧热,即由总热量减去冷凝热的差数. 常用的热值单位,kJ/kg(固体燃料和液体燃料),
