In present review, focusing on the low-copy nuclear genes, we summarize the appli-cation of these genes in the phylogenetic reconstruction of allopolyploid plants and bring forward some critical issues in this field.

以低拷贝核基因为主线，概述了其在多倍体植物系统发生中的应用和相关注意事项，并对其在多倍体植物中的表达变化及其分子机制进行了探讨，系统地介绍了国际上相关领域的研究成果和最新动向。

For modern aircraft, the antiskid braking system is one of the key airborne equipment and plays a very important role in safe takeoff and landing.

防滑刹车系统是重要的机载设备，对飞机的起飞、着陆安全性有重要影响。因防滑刹车系统发生故障威胁飞机安全的事故时有发生。

At last the suggestion of pay more attention to the relationship of mineral nutrients and pests and diseases control in intercropping system in future study was advanced.

同时阐述了矿质营养与病虫害发生的关系，并针对目前间套作系统中养分与病虫害关系研究的空白，提出今后的研究应加强间作系统中养分与病虫害控制方面的研究。

In the paper, the stability of the static states of the system was discussed theoretically and the control parameter was determined nearby the point of Neimark-Sacker bifurcation.

首先利用理论分析了一个二维离散超混沌系统的不动点的稳定性，以此得到系统发生Neimark-Sacker分岔时参数α的近似值。

By analysing the hidden dangers of gas-fired boiler room in system of burning,leak of gas and system of steam-water,the paper presents some safety measures considered during designing of blast shelter,gas pipeline,aeration and fire controlling of boiler room,and advanced some prevention measures to realize the safety run.

从燃烧系统、燃气泄漏、汽—水系统三方面分析燃气锅炉房的安全隐患，提出工程设计时在抗爆卸压、燃气管道及通风与消防等方面应考虑的安全措施，并提出了预防锅炉房事故发生的值得注意的问

Aim at the defect of commonly technique,a new technique of alarm in advance of boiler water level is put forward.this technique adopt the idea of signal catenation and blur control.alarm in advance and seek out the coming fault.the fault can be repaired before water level beyond the limit.avoiding water level beyond the limit.

针对一般方法的弊端，提出一种新颖的汽包水位预警的方法。该预警系统采用信号间的连锁和模糊控制的思想，在故障发生以前提出预警，并且找出可能发生的故障。从而达到在水位越限以前进行故障检修，避免水位越限。

By using of transgenesis, cell mutagenesis, analysis of signal pathways and genes interaction, we developed novel methods of system biotechnology for drug discovery, transgenic bioreactor and isolation of differential expression genes involved in cytogenesis .

采用转基因细胞系、突变细胞系研究细胞发生的信号传导路径、多基因相互作用与生物系统的结构–图式形成，发展了系统生物学新技术进行基因克隆、药物筛选和生物反应器的方法。

Nevertheless, due to the increase of the surface area and activity, the possibility of hydrogenolysis also increases so that more chloroform are generated with the use of nano-scale particles than with the micro-scale particles.

然而由於尺寸缩小，反应活性亦加大，奈米锡在水中对氢离子的竞争性提升，因此加强了氢解反应的发生机率，造成奈米化金属系统三氯甲烷的产率较粉末状金属系统高出许多。

With this aided system ,we can get the general function of an ichnography edit system,and also get the 3D graphic for the construction site.

利用该系统可以快速地进行施工总平面布置设计，具有一般平面编辑系统所要求的各项辅助功能，同时可以对任意工期内施工现场的实际布置情况进行三维表达或以动画方式模拟实际建筑设施随工期的推进而发生的变化。

The articles guided by the copyright theories and the traditional infringement theories and its main clue is the determination and preclusion of network infringement. The author sets out from the present conditions of the copyright infringement in our country, draws some successful experience from abroad, goes on making a complete and systematical study on some basic theories of network copyright infringement, including some specific steps: such as the standard of establishing the copyright infringement on net, concrete manifestation, the doctrine of liability fixation, the exception of the principles and the precautionary measures and remedy for copyright infringement.

本文以传统侵权理论和版权理论为指导，以因特网上版权侵权的认定到制裁为主线，从我国因特网上版权侵权的现状出发，借鉴国外成功的经验，对网络版权侵权的一些基本理论问题进行了较为全面、系统地探讨，具体包括网络版权侵权的认定标准、具体表现形式、归责原则、侵权的例外情况及防止侵权发生的预防措施和侵权发生后的制裁措施。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
