Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements(Fe3+)cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4~5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55~60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

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.

Consolidation test is a important link of obtaining mechanical properties index of soil and coefficient of compressibility gained through the test is a key data to evaluating the compressibility of soil. Consisting of solid phase and liquid phase of the salty soil is different from the non-salty one. Eutectic salt in soil may exist as liquid phase, solid phase or both of them and these phases can interconvert because it is affected by temperature, Na_2SO_4 content, water content. Especially when temperature drops, Na_2SO_4 will crystallize and expand, namely salt expansion of soil. These particularities make soil sample put in environmental cabinet when consolidation test is going on. So soil sample can be compressed by temperature controlling system under a set temperature.From experiment, the formulae counting coefficient of compressibility of salty soil have been given.
土的固结试验,是取得土的力学性质指标的一个重要环节,因为土的固结试验所取得的压缩系数,对评价土的压缩性是一个关键数据,但由于盐渍土的固相、液相组成和非盐渍土不同,土中易溶盐受温度、含盐量、含水量的影响可以以液相、固相、液相和固相混合形式存在,且它们之间的存在形式可以相互转换,尤其是当温度下降时,硫酸钠便结晶产生体积膨胀,即盐胀,这些特殊性就使得在进行硫酸盐渍土的固结实验时,须将土样放置在环境箱中,通过温度控制系统使土样在设定的温度下受压产生变形。
