Complete and articulated fossils such as these suggest that the lakes present at that time were fairly deep, to allow the anoxic conditions required for preservation.

象这些完整的和有关节的化石使我们了解到那个时候的湖泊很深，能有这样的保存缺氧条件是必需的。

The results from electron micrographic analysis show that soot oxidation is influenced by aggregation and agglomeration of soot particulates, at the same time, the crystallograms show that the previous soot particle is non-crystal carbon, but in the latter conbustion period, a very small amount of crystal soot with unstable lattice at relatively higher flame temperature is formed. The crystallization happens greatly in period of combustion when temperature is relatively lower. The smoke particulates consist of crystal carbon similar to chaoite crystal latice and noncrystal carbon.

碳粒浓度和KL变化曲线表明预混合火焰中碳粒浓度远远小于扩散火焰，其原因在于不均匀的燃油—空气混合气结构在高温缺氧条件下产生大量碳粒，在温度峰值附近碳粒浓度亦达到峰值，其后迅速氧化，当温度低于2000°K时碳粒基本上不氧化，碳粒的电子显微分析表明碳粒的氧化受碳粒的集聚过程的影响，在燃烧初期碳粒是非晶体，碳粒的结晶在燃烧后期和排放过程中大量出现，排放碳烟微粒由晶体和非晶体碳组成。

The use of the phosphorus uptake and denltrification of PAOs under anoxic conditions for the realization of the simultaneous removal of nltrogen and phosphorus is a method with practical prospect for munic－ipal sewage treatment,and the establishment of the mathematical models of denitrlfication and dephosphorization by activated-sludge process benefits the popularization and application of this technofogy.

利用聚磷菌在缺氧条件下的吸磷和反硝化作用，实现氮、磷的同时去除，是具有实用前景的城市污水处理方法，而建立活性污泥法脱氮、除磷的数学模型则有利于该项技术的推广应用。

It is now known that seere hypoxia-ischemia may not cause immediate cell death, but may precipitate a complex biochemical cascade leading to the delayed deelopment of neuronal loss. These phases include a latent phase after reperfusion, with initial recoery of cerebral energy metabolism but EEG suppression, followed by a secondary phase characterized by accumulation of cytotoxins, seizures, cytotoxic edema, and failure of cerebral oxidatie metabolism from 6 to 15 h post insult.

现在认识到严重的局部缺氧有可能不立即引起细胞坏死，但是可能促成一种复杂的生化级联反应，这可能导致神经元丢失，进而导致延缓发育，这些时期包括再灌注后的潜伏期，该期出现早期的脑能量代谢复苏但脑电图却呈抑制状态，紧接着第二期表现为损伤后6－15个小时细胞毒素，癫痫，细胞毒性水肿，脑氧化功能衰竭的累积。
