Environment-friendly bast fiber film is buried in the ground floor of different soil pH value to study degradation and changes in the type and quantity of micro-organisms, to explore environment-friendly bast fiber film degradation relevance between micro-organisms and soil pH value. There are three types of soil, for example, weak acid soil, neutral soil, weak alkaline, in which film is buried. It is to determinate of weight loss and changes of quantity of micro-organisms around.

为了探明麻地膜降解性能与土壤pH和土壤微生物的相关性，利用生石灰调节土壤pH，将土壤pH调节为弱酸性、中性、弱碱性3个不同的水平，将麻地膜埋入3种不同的土壤中，定期测定其失重率及其周围土壤微生物种类和数量的变化。

Using the aforementioned experimental methods,the author has performedcareful study on the thermoanalytical characteristic of nanocrystalline brookite-basedTiO2,and found that on the DTA curve there exists a small irreversible endothermicpeak,which is related to the dramatic structural phasetransformation from brookite to anatase then to rutile.

利用上述实验手段，作者首次对板钛矿基(brookite-based)纳米TiO2的热分析特性进行了较系统、深入的研究，发现在DTA曲线上存在一较小的不可逆、无失重吸热峰，对应于从板钛矿经锐钛矿到金红石的急剧转变。

Three experimental groups of the cultured rat osteosarcoma cells underwent simulated weightlessness in rotating clinostat for 24, 48 and 72 h respectively.

目的 通过观察回转条件下培养的大鼠骨肉瘤细胞内Ⅰ型胶原的基因和蛋白表达的变化，探讨模拟失重对成骨细胞增殖功能的影响。

The flame retarding mechanism of MCA on POM was that formaldehyde and formate acid were absorbed by melamine resulting from melamine cyanurate pyrolysis and temperature of burning materials was reduced because melamine cyanurate sublimation absorbed heat and thermalplastic polyurethane absorbed formaldehyde and enhanced stability of POM composites.

热失重、红外和气质联用分析表明，MCA／TPU复合阻燃剂对聚甲醛的阻燃作用是由于三聚氰胺氰尿酸盐高温分解并吸热，降低材料燃烧区域的温度；另一方面MCA高温分解生成的三聚氰胺可吸收聚甲醛分解产生的甲醛和甲酸；此外，TPU可提高聚阻燃甲醛的热稳定性，有利于阻燃。

Some conclusions were summarized as following: wood、 paper、 fabric and kitchen rubbish have the resemble pyrolysis characteristics; it is obvious that plastic"s decalescence happened during it"s pyrolysis process; the range of τ_max from great to small in sequence is plastic、 rubber、 fabric、 paper、 kitchen rubbish and wood.

其次，本文对垃圾典型组分的快速热解特性作了研究，并同程序升温时的热解特性作了比较，得到以下一些结论：木屑，纸屑，织物和厨余，其热解特性具有相似之处，微分转化率曲线均表现为单峰曲线；塑料在反应时存在较明显的吸热现象；τ_max(最大失重率所对应的时间)由大到小依次是塑料，橡胶，织物，纸屑，厨余，木屑。

It will also go a little higher than its predecessor, so that its passengers will experience five minutes or so of weightlessness before flying back to receive their astronauts' wings. But, crucially, it has the same flip-up wings.

星船二号的飞行高度将比它的前辈略高一些，这样乘客将有五分钟左右的时间来体会太空的失重状态，然后回到地球接受宇航员的飞行章。

The erosion-corrosion mechanism of AISI1020 in artificial sea water with or without 1000×10-6 silica sand under sudden pipe expansion condition was investigated through weight loss test, surface morphology observation,local flow regime measurements and electrochemical measurements at specific position.

利用新近研制的双相流冲刷腐蚀激光多普勒实验装置，通过失重测试\表面形貌观察、局部流速流态测试和典型部位的电化学测试，研究了突扩管条件下碳钢AISI1020在单相及含砂人工海水介质中的冲刷腐蚀机理。

Its heat-resistant and flame-resistant properties were analyzed using TGA and Oxygen Index respectively.

树脂具有明显的高邻位树脂的特点，体系粘度低，合成易于控制；树脂具有良好的耐热性和阻燃性，80 0℃热失重低于 30 %，氧指数大于 4 7%。

Therefore, it is requisite to carry out medium-term or long-term microgravity countermeasures in light of the health, safety and performance of the astronauts.

因此，为了保证航天员的身体健康、安全及工作效率，开展中长期失重对抗措施的研究是非常必要的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
