物质

The short lifespan and excessively high death rate of enterprises have been attracting more and more attention from people.

一、问题的提出企业作为物质财富的创造者，是支撑世界和各国迅速增长的人口的物质和文化生活水平的不断提高，推进人类文明进程的主要因素。

One example is a part of the brain called the hippocampus, which is a primary locus of memory formation, but which can be seriously debilitated by chronic stress.

有一个例子是大脑中称为海马体的物质。这种物质是记忆形成的主要场所。长期的精神压力会使它产生严重衰竭。

Generation of product was observed under340～370nm in the reaction of rutin and α-hydroxy ethyl peroxyl radical. The observed1st order build-up and decay of the new product was calculated to be (1.11±0.08)〓, respectively.

在340～370nm观察到了芦丁与有机过氧自由基反应体系中新物质的生成，并计算得到了新物质生成和衰变的的表观一级反应速率常数分别为〓和〓。

The active layer in MEEF composed of the granular material from plants, where earthworms act as declogger, decomposer and facilitating a nitrification-denitrification process within the biofilm.

蚯蚓在滤床中起分解和利用污水和污泥中的有机物和营养物质、清通滤床以及促进含氮物质的硝化与反硝化作用。

It connects different factories or enterprises by the way of transmitting material flow or energy flow, to form industrial symbiosis networks by sharing the resource and mutual exchange by-products. Under this pattern,"by-product" of one producing process may be the raw material of another process. In order to explore material closed circular, energy conservation system and minimum discharge of the waste, it set up the circular pathway by imitating the natural circular system as"producer—consumer-- decomposer"in the industrial system.

它通过物质流或能量流传递等方式把不同工厂或企业连接起来，形成共享资源和互换副产品的产业共生组合，使一家工厂的废弃物或副产品成为另一家工厂的原料或能源，模拟自然循环系统，在产业系统中建立"生产者—消费者—分解者"的循环途径，寻求物质闭路循环、能量多级利用和废物产生最小化。

Results PKCγ immunoreactivities were located in the pyramid, decussation of pyramid and the ventral part of posterior funiculus in the cervical, thoracic, lumbar and sacral segments of the spinal cord.

结果 PKCγ免疫阳性物质分布于锥体、锥体交叉及脊髓颈、胸、腰、骶段后索腹侧中；延髓和脊髓背角神经元中也有PKCγ免疫阳性物质存在。

This article reviewed on the definiens of allelopathy, allelochemical categories and interactants of them. Acting modes of the allelochemicals were discussed. The use of allelopathy and allelochemicals of plants to agriculture production was introduced. The existing problems and direction in the study on plants allelopathy were advanced in the end.

笔者综述了植物化感作用的定义，化感物质的种类及其相互之间的关系，化感物质的作用机制，并介绍了化感作用在农业生产中的应用及其前景，展望了化感作用研究的范围和方向。

This low carbonate event may have resulted from changes of rainfall. During deglaciation, the dry climate caused a decrease in terrigenous sediment input. However, during Early-Middle Holocene, the rainfall, especially the heavy rain with higher erosions increased rapidly, leading to the increase of terrigenous sedimental supplies from South China mainland and Hainan islands.

在冰消期，出现干旱，陆源物质减少，而早中全新世的雨量，尤其是具较强冲刷能力的大雨量急剧增加，造成北部海南岛和华南陆地的冲刷增强，陆源物质供给增加，从而出现低钙事件。

The dematerialization was defined to be using less materials while providing the same or better service or function.It does not mean that materials and energy can be totally saved,but it meant that the high welfare economy could be realized through maximizing the usage of resources and energy.

循环经济这一物质闭环流动型经济，是以"减量化、再利用、资源化"为原则，以物质闭路循环和能量梯次使用为特征，这一发展模式的关键其实就是非物质化。

If the doing-more-with-less concept, also known as "dematerialization," had an effect on overall materials usage, the United States - a major player in technological innovations - would have been a beneficiary; per capita use of materials would have continually shrunk.

如果"少投多产"，即"非物质化"的概念对于总体物质消耗有用的话，那美国——技术创新的主角——应该是受益人；人均物质消耗应该持续降低。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.

通过X射线衍射分析可知，用混合偶联剂对滑石粉进行预处理后，滑石粉晶体结构发生改变，产生了插层现象，使PP／滑石粉复合材料为纳米复合材料。

An authentic Maui wedding might require the services of a 'kahu', which is a Hawaiian minister.

毛伊可能需要一个真实婚礼服务'kahu'，这是夏威夷部长。
