Total genomic DNA was extracted from four marine fishes (Verasper variegates, Cleisthenes herzensteini, Turbot Scophthalmus maximus, red seabream Pagrosomus major) using a proteinase K and phenol-chloroform procedure. Long mtDNA fragments were amplified by long and accurate PCR using primers designed based on the mtDNA sequenses of Thunnus thynnus thynnus, flounder Paralichthys olivaceus and other related fishes.

A 1172 bp fragment was detected for Wx-7A gene using dominant marker primer from the Wx-A1 normal wheat, a 593 bp and a 574 bp fragment were detected using codominant marker primer from the Wx-A1α normal and Wx-A1 null wheat, respectively.

STS标记结果中，Wx-7A位点的显性标记引物在野生型中扩增出一条1172bp的特异带，即Wx-A1α基因出现；Wx-7A位点的共显性标记引物在野生型中扩增出一条593bp的特异带，在缺失类型中扩增出一条574bp的特异带。

Guglielmo Marconi, recognizing the possibility of using these waves for a wireless communication system, gave a demonstration (1895) of the wireless telegraph, using Hertz's spark coil as a transmitter and Edouard Branly's coherer (a radio detector in which the conductance between two conductors is improved by the passage of a high-frequency current) as the first radio receiver.

Guglielmo Marconi，认可使用这些波浪的可能性为一个无线通信系统，给了一次示范(1895)无线通信机，使用赫兹的火花卷因为发射机和Edouard Branly 的coherer (导率在二个指挥之间被高频率潮流段落改进)的一台无线电探测器如同第一无线电接收机。

A rapid, efficient protocol to detect the toxicity of Cu2+ stress using wheat coleoptile, which is simple, uniformal in structure and sensitive, was established. By using this model, the mechanism of Cu2+ stress leading to the inhibition of cell elongation was also studied.

本文以小麦为材料，研究不同浓度Cu2+对小麦种子萌发和幼苗生长的影响及机理；利用小麦胚芽鞘结构简单、反应敏感的特点，探索建立小麦胚芽鞘快速检测铜离子毒害模式，并利用此模式研究了铜离子胁迫对细胞伸长抑制作用的机理。

It was difficult to estimate the model parameters by using conventional methods due to the model collinearity, so a new compensation method using the finite impulse response model was proposed.

鉴于模型参数之间存在很强的复共线性，提出了基于有限脉冲响应模型飞机磁场补偿方法。

This paper puts forward to a new way of generating colored noise using a novel all-filter phase digital filter. Compared to traditional FIR filter, the colored noise generated by using this filter has fewer spectrum leak, higher stop band attenuation.

本文提出用全相位数字滤波器这种新型滤波器滤波白噪声产生有色噪声的方法，这种方法比用传统FIR滤波器产生的有色噪声频谱泄漏少，阻带衰减功率大等优点。

The second option is to extract the track directly from the aerogel in a "keystone", using an extraction technique that we developed here at Berkeley specifically for Stardust and have been using successfully for several months on the cometary collector.

第二种方案是直接从气凝胶中提取出含有轨迹的楔形块，用的是我们在伯克利特别为 Stardust 开发并在数月前成功用在彗星收集器上的提取技术。

PbWO4 and CeF3 which are newly developed inorganic scinti1latr in our country have been studied. Photo-electricity detector systemes which have high γ sensitivity and relative insensitive to neutron and fast time response were assembled by using CeF3 and photomultiplier tube. The ratio of signal-to-noise for γ ray detection can be up to more than 10 times in close distance n,γ commix pulse radiation field by using this detector system.

对PbWO4和CeF3等近年国内新研制的无机闪烁体进行了系列研究，使用CeF3分别配光电倍增管和光电管，组合出了对γ辐射灵敏度高，对中子相对不灵敏，同时脉冲响应也快的光电探测系统，应用以此为基础的探测技术在近距离n，γ混合脉冲辐射场中，可将脉冲γ辐射探测信噪比提高一个量级以上。
