结果表明，采用自蔓延高温合成技术制备WC－Al2O3复合陶瓷材料时，气相产物的生成及挥发是影响反应参数和合成产物相组成的重要因素。

The hydrothermal behavior of various types of alumina was investigated by means of XRD,which were derived from calcination of gibbsite,bayerite and nordstrandite at temperatures below 1000℃ and normal pressures or in vacuo.

用XRD方法研究了α－三水铝石在常压及真空中1000℃以下的脱水产物和湃铝石／诺水铝石在常压1000℃以下的脱水产物，经170℃水热处理和自身压力条件下的晶相变化。

To understand the impact of plant canopy photosynthate inputs on soil nematode communities, a large-scale tree girdling experiment was conducted in a evergreen broad-leaved forest of Ailao Mountains.

3为了解植物光合产物通过根系实现的地下资源输入对土壤生物的影响，本研究通过大规模的环割实验切断植物向地下运输光合作用产物的通道，研究了环割前后土壤微生物生物量、土壤线虫密度和多样性的变化。

Glyceraldehyde, glycoladehyde, glycolic acid, and formaldehyde were identified as the intermediate products.

甘油光催化降解最终产物是H_2O和CO_2，检测到了甘油醛、羟基乙醛、羟基乙酸、甲醛等中间产物。

Otherwise, this one act of Intel can allow the product line with automation supplier existing throw the helve after the hatchet only, come through more and contemporary small controller the product with brand-new research and development.

否则，英特尔的这一行动只会让主动化供给商完全抛却现有的产物线，并经由过程更多现代的微节制器来研发全新的产物。

Therefore, we suggest that for heptane larger surface area is beneficial for higher photocatalytic activity.

而在降解甲苯的过程中，会生成反应活性很低的中间产物，这些中间产物覆盖在样品表面的活性中心，会影响其后进行的光催化反应。

C〓 thiophene didn't exist in aromatic fraction at 200℃, but very abundant at 300℃, indicating that heterotrophy resulted in the disappearance of chlorophyll which had transformed into more stable compounds with phytane side chain.

在200℃热模拟产物芳烃组份中不存在C〓噻吩，而300℃热解产物中该化合物含量较高，这可能暗示着异养黄化作用导致了叶绿素消失，并转化为更加稳定的具植烷侧链化合物。

The reform open, the economic development of China obtained the achievement that the whole world focus attention, but at the same time, the pollution of the environment is also very serious, a lot of ecosystem of place depravation, the acid rain, water pollution, soil run off, the hungriness turn, the air pollution etc.

恩格斯曾经指出："人本身是自然界的产物，是在他们的环境中并且和这个环境一起发展起来的。"这一论述已精辟地剖析了人与环境的关系：作为生物进化最高阶段的人类，是地球环境演化的产物，生态环境是人类赖以存在和发展的物质基础；人类是在不断地利用、改造生态环境的过程中逐渐发展起来的。

The fermentation product of Acetobacter xylinuml.1812 was hydrolyzed by acid or cellulase, then it was proved that there was glucose in the hydrolyte by TLC and chromatography mass spectrometry, thereby the product was identified as bacterial cellulose.

通过薄层层析和气-质联谱测得木醋杆菌发酵产物经酸或纤维素酶水解后的水解液中主要成份为葡萄糖，从而鉴定出发酵产物为细菌纤维素。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
