By regression of experimental data, therules of the linkage between these factors, which will provide a theoretical basis for designing BBP with different scales.3 Using thermal analysis technology and dynamic thermogravimetry, the paper studies combustion kinetic characteristics of 3 types of agricultural crops at different rate of temperature rise, and thus, achieved dynamic parameters of these fuels at different rate of temperature, established dynamic model of straw combustion, which reflects the dynamic process in the fast combustion area.4 Characteristics of straw briquette combustion was experimented, focusing on the impact of straw type, temperature, air supply, and density, diameter, and weight of briquette on the combustion speed, and the following conclusions were drawn:(1) combustion of straw briquette fuel is static permeation diffusion combustion;(2) temperature has a larger impact on the speed of straw briquette combustion than air supply; the higher the combustion temperature is, the faster volatilizable component separates out, and the less steady the combustion is;(3) density of briquette fuel has impact on the speed of volatilizable component separation and therefore the combustion speed;(4) increase of diameter and weight of briquette fuel increases the average combustion speed in the initial stage, and that in the later stages is comparatively steady;(5) the proportion of volatilizable component in straw briquette fuel is high, therefore, the temperature control during combustion under the rational ventilation condition is essential to ensure its safe combustion.5 Using the above-mentioned results of experiments and theoretical analysis, and based on thought of hydraulic driven and bi-direction compression, the hydraulic system and compression parts of the HBP BBP are re-designed in terms of industrialization.

Compared with the single-bounded questionnaire format, the double-bounded questionnaire format could obtain more information about the respondents' willingness to pay, hence, it reduces the confidence interval range and improves the estimation accuracy of the greatest willingness to pay. At the pilot practice for three continuous years, the percent of banana windstorm insurance pilot size in the total banana planting area was less than 10% in Hainan. Combined with this research result, the author holds that Hainan finance should strength the subsidy to banana windstorm insurance on the basis of 30% subsidy in two continuous years of 2007 and 2008, and the subsidy percentage should try to achieve 40%. At the same time, the premium rate should not be too low, 18% is suitable.
