&Dubster &是一个源于字母W、听起来很年少的昵称（这与里根昵称之一的&Gipper&很像），用以区分小布什和他的父亲老布什。

Under the same conditions, irradiation with ultraviolet lamp at a power of 1.5 W/m 3 and radiation intensity of 90 μW/cm 2 for 30 min produced the germicidal efficacy similar to that produced by 2 g/m 3 Chinese drug candle fumigation disinfectant.

在相同条件下，以功率 1。 5W/m3、辐射强度 90μW/cm2 的紫外线灯照射 30min，其杀菌效果与 2g/m3 中药蜡烛烟熏消毒剂相似。

For example, it may prove difficult to cope with the in-furnace aerodynamic characteristics resulting from the use of a swirl burner on the arch-crown of the W-shaped boiler. In such a case one will not only be deprived of the advantages attributed to the use of the swirl burner but also suffer from a multitude of troublesome issues.

但采用旋流燃烧器后，由于W型锅炉燃烧的特殊性，给锅炉的设计和运行带来了新的情况，如对旋流燃烧器在W型锅炉拱顶采用旋流燃烧器后炉内的空气动力特性不能很好得到掌握，不但得不到旋流燃烧器所带来的优点，还会引起很多问题。

The results are as follow:The diploid chromosome number of Taihe Silkies was 2n=78,the basic number of chromosome arms was AF=90 and the sex chromosome type was ZZ/ZW.According to the measured relative length,arm ratio and centromeric index,the first 10 pairs of macro-chromosomes are described as follows:No.1 ,9 and Z,W chromosomes were metacentrics,No.2,4,7 were submetacentrics,and No.3,6,8,10 were telocentrics.Studies on Taihe Silkies′ G-band showed that the first 10 pairs of macro-chromosomes can be divided into 29 zones and 190 bands.

结果表明：泰和乌骨鸡体细胞染色体数目2n=78，染色体基本臂数AF=90，1、9号染色体及Z、W性染色体为中央着丝粒染色体，2、4、7号染色体为亚中央着丝粒染色体，3、6、8、10号染色体为端着丝粒染色体。G带研究表明：前10对大型染色体可分为29个区，190条带。C带处理发现，所有母鸡分裂相中W性染色体都出现C带并整条深染。

In this paper, W-Cu alloys with different percentage composition of Cu have been obtained by hot extrusion.

通过对不同铜含量（Cu质量分数20%~50%）的W-Cu混合粉末进行热挤压，获得了具有不同成分配比的W-Cu合金，并研究了铜含量对热挤压坯料组织和性能的影响。
