查询词典 reciprocal difference

The difference between the test groups and the control group was statistically significant. It could be deduced that all the insecticides tested in this experiment damaged the spiders′ intestinal mucosa, compromising its function as a barrier and letting large molecules such as FTIC-D more easily penetrate. Among the insecticides, pyrethrin and Bt preparation are bio-insecticides, and the FITC-D concentrations of the spiders exposed to these two bio-insecticides were more than those of the spiders exposed to the chemical insecticides imidacloprid and dipterex. The difference between the bio-insecticide groups and the imidacloprid group was significant, but there was no significant difference between the bio-insecticide groups and the dipterex group.

结果表明：4种杀虫剂处理后拟环纹豹蛛血液中的荧光素浓度远高于对照组，各个处理组拟环纹豹蛛血液样本中的荧光素浓度均与对照组存在极显著差异，可见4种杀虫剂均将对拟环纹豹蛛肠黏膜的屏障功能造成损伤，导致大分子物质易于通过；其中1.5%除虫菊素水乳剂三保奇花和Bt制剂强杀处理后拟环纹豹蛛中肠黏膜的通透性高于仿烟碱类化学杀虫剂吡虫啉处理组，差异达到显著水平，但与有机磷杀虫剂敌百虫处理组差异不显著。

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.
