The study on the phylogenetic relations among these species is very useful for the study on genome and marker-assisted breeding in Brassica species. The karyotypic analysis is one of the most important methods in analysing the phylogenetic relation of species with closer relations. The protocol for inducing high frequency metaphase was established by pretreatment with low temperature and 8hydroxyquinoline, and then the preparation of chromosome and karyotypes analysis of six economical important Brassica species were carried out. According to the karyotypic analysis, it was shown that in the genomes of amphidiploid species, there are genomical components from didiploid species. Our result showed that B. campetris, B. juncea and B. napus belonged to class 2B, while B.

以二倍体B.nigra（B，n=8）基因组为探针，用B.campestris（A，n=10）或B.oleracea（C，n=9）的基因组进行封阻，分别与B.juncea（AB，n=18）和B.carinata（BC，n=17）进行GISH杂交发现，B.juncea和B.carinata基因组中仅有来自于B.nigra的8对染色体表现杂交信号，而其它染色体杂交信号较弱；以B.campestris或B.oleracea基因组为杂交探针与B.napus（AC，n=19）进行GISH杂交发现，所有19对染色体均出现杂交信号，根据杂交结果难以正确判断B.napus基因组中的哪些染色体是来自于A基因组，哪些是来自于C基因组；以rRNA基因（18S-5.8S-26S）为探针的FISH杂交结果表明，B.campestris基因组中rRNA基因位点为6对；B.oleracea为3对；B.nigra为2对；B.carinata为4对；B.juncea为6对；B.napus为6对。

The recent studies have indicated that direct visualization of the distribution of local anaesthetics with high-frequency probes can improve the quality and avoid the complications accompanied by the traditional procedures.

最近的研究亦表明在高频超声直视下局部注射麻醉剂能够有效的提高麻醉质量及明显的降低传统神经阻滞引起的并发症。

In particular, such as the sensors of images, high-frequency and analog units.

The high frequency of Zero anaphora is one of the main characteristics of Chinese yet its appearance varies in different literary styles.

零形回指在不同的语体中有不同的使用特点。

There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.

因为实际面板在运作时就是闸极与汲极采用交流方式操作，所以接著探讨在闸极上与汲极上给予直流正、负偏压与交流正、负偏压应力测试，来比较非晶矽薄膜电晶体在闸极与汲极分别有偏压下，电晶体的最大衰退变化量，再加上闸极与汲极给予非同步偏压的状况，探讨此一非同步状况对於电晶体的影响，以及了解是哪些机制造成如此差异。
