模拟实验

Based on the compared and simulated experiment, it was quantitively studied on the effect of macrobenthos (Ilyoplax deschampsin and Corbicula fluminea) on the exchange of nutrient across the sediment-water interface and the early diagenesis of nutrient in the tidal flat sediments from the Yangtze Estuary. Ilyoplax deschampsin and Corbicula fluminea affected the exchange of nutrient across the sediment-water interface by the different biological mechanisms.

The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。

In this paper,the treatment of water stress to Cryptomeria japonicaD.Don seeds was made by the different concentrations of polyethylene glycol.

It can be found that the IPCA, as a non-iterative method, can obtain one principal component by only one calculating process. Therefore the IPCA is not only fast in calculation, but can avoid the cumulative error suffered by iterative methods.

使用模拟和实验HPLC-DAD数据对IPCA进行了验证，结果表明IPCA是一种非迭代方法，只需要完成一次计算过程即可得到一个主成分，因此IPCA不仅能够显著提高运算速度，而且可以避免迭代法中的误差积累问题。

Alkylphenols are applied widely as the rubber additives surfactants in domestic and industrial products, antioxidants and so on. As it's decomposer, nonylphenol has a steady chemical characteristics and exist widely in environment. As it's molecule structures are similar as 17beta-estradiol in human body, and it can combine with estradiol receptor simulating it, disrupt endocrine system and induce health damage effect. Many studies on environmental endocrine disrupting chemicals approved that NP have weaken estradiol functions.

烷基酚被广泛用作塑料增塑剂、农药乳化剂、纺织行业的整理剂等，作为其降解产物壬基酚(nonylphenol，NP)的化学性质稳定，环境分布广泛，由于其分子结构与人体内雌二醇的分子结构相似，许多环境内分泌干扰的实验研究结果证实壬基酚具有雌激素样作用，可以模拟雌激素与体内雌激素受体结合，干扰机体的内分泌代谢，导致健康危害效应。
