上位的

The androecium were consisted of 3 stamens,two of which were connate ,separating or partial combination.

摘 要 对南瓜的两性花进行外部形态及结构的研究，结果表明：南瓜的两性花可有子房上位花、子房半下位花和子房下位花三种类型：花萼、花冠均为5，合瓣；雄蕊3，其中有两枚各由两个雄蕊合生而成，分离和部分联合，花药结构特殊，花粉发育正常；雌蕊具有单个或两个柱头及花柱。

It realizes the distribution system ideal, which is distributed control, centralized management.

上位机管理监控系统的研制成功实现了分布式系统所提出的"分散控制，集中管理"的目标。

On this system the up-location computer is composed of industrial computer and the Beijing configuration software, the disperser control of lower position computer use sanling PLC of Q series, which constitute a collection and distribution control system.

该系统上位机采用工控计算机与北京亚控的工控组态软件的组合，下位机分散控制的构成方式采用了三菱Q系列PLC，构成了一个集散控制系统。

In Chapter 5, the software frame of the embroidery machine control system is constructed in the light of the hierarchy of master system and slave system. The programs of keyboard entry, graphical display, USB drive, pattern store and management, serial communication and electromechanical control are designed.

第五章按照上位机和下位机的层次构建了绣花机控制系统的软件框架，设计了键盘输入模块、图形显示模块、USB驱动模块、花样存储与管理模块、串口通信模块、机电控制模块的程序。

This system is a distributed and distant communication system with PC as epigyny computer and 8098 SCM as hypogyny computers. The authors deeply research hardware structure and soft design of this system and draw up a plan for this system.

该系统是由PC机为上位机、6台8098单片机为下位机的远距离分布式通信系统，作者对系统硬件结构和软件设计进行了深入的研究，提出了系统的实现方案。

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。

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。

Rather, he says, the most likely explanation is a phenomenon known as epistasis, where genes can interact so as to greatly multiply an effect.

戈德曼还说，当然可能性最大的解释是有一种被称为"上位性"的现象，在这种现象中基因可以发生大大增加某种效应的相互作用。

The results reveal that many QTLs are involved in epistasis, and the same locus can get involved in interactions with more than one other locus.

结果发现，QTL除了具有自身的效应外，还可以参与上位性效应的形成，一个QTL可与多个QTL发生互作，可能起到诱发和修饰其他位点的作用。

Besides, two and three pairs of genotype-environment epistasis QTL are detected for RUS and LSUE respectively. Only one of these that controls RUS displays a significant effective value.

QTL与UV-B辐射互作分析发现2对控制根系硅吸收能力和3对控制叶片硅利用率的基因×环境上位性QTL，其中只有1对控制根系硅吸收能力的QTL效应值较大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
