This paper expatiate TP touch screen as a epigyny machine management system and the Plc system applied in the silicon oil emulsification and production,This system provide great advantage in the silicon oil emulsification and production,the main system specialties are the TP is communicated with PLC by RS232,greatly improving the efficiency of the silicon oil emusification and production with few malfunction and easy to real time inspection.

本文主要阐述了TP触摸屏作为上位机管理系统与 PLC通讯在硅油乳化生产中的实际应用，该系统在硅油乳化生产中有较大的优越性，系统特点是触摸屏与系统通过 RS232 串行通讯，达到管理与控制相结合，便于实时监控，减少了故障率，大大提高了硅油乳化的生产效率。

Introduces core of AVR single chip ATmega128, Use unconnect card collection system of highway ,Given hard ware design ,Compile collection soft ware based on data-base and VB. Achieve communication with epigyny computer,.

给出了系统的硬件设计，同时基于数据库技术并采用VB编写了收费系统软件管理系统，并实现了与上位机通讯，最后分析了 IC卡收费系统的安全性措施。

Analyse the status of the charge collection system of the motorways and indicate its demerits. Introduces core of AVR single chip ATmega128, Use unconnect card collection system of highway, Given hardware design, Compile collection software based on database and VB. Achieve communication with epigyny computer. Lastly analyse IC card collection safety. It simulate collection from Xi'an to Tongguan. Experiment attest high efficiency, rapidness and safety.

分析了当前高速公路收费系统的现状，指出了其存在的不足和缺陷，提出了以AVR单片机ATmega128为核心处理器，采用非接触式IC卡技术的高速公路收费管理系统；给出了系统的硬件设计，同时基于数据库技术并采用VB编写了收费系统软件管理系统，并实现了与上位机通讯，最后分析了IC卡收费系统的安全性措施；该收费系统模拟了西安至潼关的高速公路收费，实验证明该系统具有收费效率高，放行速度快，安全性高等特点。

Developmengts anslysis on plant high, caulis leaves and single fruit showed with coincident disciplinarian, but distributing unlikeness. From seedling time to flourishing time, 2 importing varities's developments curve were keeping epigyny, showed that importing tomatoes varities had obvious advantage on plant high, caulis leaves and single fruit, and had bigger increase production potential.

株高、主茎叶片数和单株果数等3个测试指标的动态分析表明，规律一致但分布不同，2个进口品种的动态曲线从苗期到盛果期始终保持上位，说明进口品种在株高、主茎叶片数和单株果数3个生长发育指标上具有明显优势，植株生长旺盛，增产潜力大。

This relationship between number of mutations and fitness is known as synergistic epistasis.

这种突变数量与适合度之间的关系被称为增效性上位。

However, We think that heterosis is caused by the complex effects of dominance, over-dominance and epistasis.

作者认为，杂种优势的产生是显性效应，超显性效应和上位性效应共同作用的结果，不可能只是一种基因效应在起作用。

With the epistasis existed, MIM would obtain better estimates of QTL additive effects.

在有上位效应存在的情况下，MIM 对QTL 的加性效应的估计较准确。

Except for major QTLs, epistasis played an important role in the genetic basis of yield and fiber traits in upland cotton.

除了主效QTL外，上位性是陆地棉产量和纤维品质性状的重要遗传基础。

Finally,the information about QTLs and epistasis in the population provide strategiesfor manipulation of heterosis and improvement in hybrid rice.

最后，本文就上位性效应对杂种优势遗传研究和杂交水稻遗传改良的影响进行了讨论。

Furthermore, it was indicated that epistasis was the main genetic dynamics of speciation and adaption and the primary genetic component of heterosis and complex traits.

遗传物质间上位性是物种分化和适应的重要遗传学动力，也是复杂性状和杂种优势形成的重要遗传组分。

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。
