In short, The formation of model has important significance for the development ofsolid biomass gasifier.

模型的建立对于发展固体生物质气化器的设计理论有重要意义。

Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel.

气化炉往往认为是简单的装置，可以从任何物质燃料和可燃气体。

At present, America visualizes the nuclear energy as its core part, while other energy produced by sun, wind, biomass, geothermic and ocean are all in a procession.

美国现阶段对新能源构想的核心部分是核能，而太阳能、风能、生物质能、地热能、海洋能等的开发也在齐头并进。

None of the four models could work well in the scenario 2, under explored stock, however they got accurate results in scenario 1, regulated stock. The Schnute model work well in full explored stocks such as scenario 1, 3, 4 and 5, especially in low biomass stocks such as scenario 3, but not suitable to the under explored stocks such as scenario 2. The W-H model generally performed well in all kind of scenarios especially in scenario 1, 4, and 5. In the swordfish, xiphias gladius, fishery, estimation of W-H model and D-Fox model produced MSY about 14000 ton, very near the result of Prager in 1996.The author tentatively explored the suitable fishing condition for the models to stock assessment.

四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差；Schnute模型在充分捕捞的渔业如渔业1、3、4、5、尤其是在低生物量的渔业3中评估效果较好，但不适合评估未充分捕捞的渔业，如渔业2；Walters-Hilborn模型适用于各种渔业，尤其是渔业1、4、5；在过度捕捞渔业中如渔业3、4，模型对参数q的估计较其它参数接近真值；在北大西洋箭鱼渔业的评估中，W-H模型和D-Fox模型对MSY的估计约为14000吨，接近于Prager(1996)的结果。

Globularia, the root biomass fraction of seedlings of the others increased with the increment of altitude.

除小叶红光树外，其它幼苗的根生物量分数均随海拔增高而增加。

The effects of different tillage practice on system of summer sowing soybean (Glucine max CYFeng Shoul2) including soil temperature, soil water and nutrients as well as biomass dynamic with different phonological stage were examined at Xifeng loess plateau, Gansu province.

本研究综合应用生物学、农学、生理生态学和土壤科学的技术与方法，2001年在甘肃西峰黄土旱塬区，以夏种大豆(Glucine max CV丰收12号)为试验材料，采用水土保持耕作技术，对不同耕作方式下土壤温度、水分、养分动态和夏种大豆生长发育、光合生理生态特征进行了系统研究。

Objective To study the growth rhythm of height, diameter at ground and the distribution of biomass of annual seedlings of Glycyrrhiza uralensis.
