The sheep trucks and horse trailers unloaded at the trailhead and a bandy-legged Basque showed Ennis how to pack the mules, two packs and a riding load on each animal ring-lashed with double diamonds and secured with half hitches, telling him,"Don't never order soup. Them boxes a soup are real bad to pack."

运羊的车和马车在路口卸了下来，一个两腿往外弯的巴斯克人教Ennis怎么往骡子身上装货，往每个牲口环上挂两个包裹——环上扎了两个钻石用半个结固定好——巴斯克人跟他说"千万不要叫汤，这些汤盒子真的很不好带"。

A low in-band phase noise FM frequency synthesizer has been depicted in this paper. It bases on the fraction N PLL frequency synthesizer, and the THD of the system has been improved greatly by this closed loop modulation mode.

研制一种低带内相位噪声的立体声FM频率合成器，该合成器基于小数分频锁相环技术，利用闭环方式对载波信号进行调制，显著提高系统的THD。

A new method of high aspect ratio and resolution zoneplate fabrication using both electron beam lithography and X ray lithography technology is described The zoneplate, composed of 10μm thick Au with 30 zones and outest zone width of 0 5μm, can be used as a focusing and chromatic dispersion device for 0 1～1nm harder X rays Results show that the zoneplate has contrast of 10 and above, resolution of 0 55μm, and focus length of 21 3cm for 8keV X ray

介绍了利用电子束和 X射线束双曝光技术制作大高宽比高分辨率的 X射线聚焦或色散元件的新方法(波长范围为 1～ 5 nm )。所制做的厚度为 10μm的 Au波带片具有 30个波带，最外环的宽度为 0 。5μm。实验表明：对 8ke V的 X射线来说，波带片的衬度大于 10 ，分辨率为 0 。5 5μm，焦距为 2 1.3cm。

Aggregation causes moderate downshifts(2～6 cm-1) for high-frequency modes involving the in-plane CC/CN stretches of the porphyrin core and a dramatic upshift (12 cm-1) for the out-of-plane saddling mode of the porphyrin ring.

聚集体的形成导致H8TPyP6+的卟啉环CC/CN面内伸缩振动向低波数方向位移2～6 cm-1，而卟啉环鞍形面外振动带向高波数方向位移12cm-1。

ABSTRACT: Random amplified polymorphic DNA was used in analysing the relationship among twenty-six speices of Amanita from Mangshan, Hunan. Of 40 primers, 6 ones generated reproducible RAPD profiles, and each one produced 1-10 bands. Two primers (OPG15 and OPH04) could differentiate 26 species of Amanita by its RAPD profiles. The similarity coefficients obtained from profiles generated by six primers among Amanita were about 20-60%. A dendrogram was constructed using average linkage clustering for clustering analysis. It indicated that there were two groups in 26 species and some species with ring and membranous volva clustered a group which coincided with morphological classification.

本文对采自湖南莽山的26种鹅膏菌属真菌进行了随机扩增多态性DNA分析，40个随机引物中筛选出扩增效果较好的6个引物，每个引物能产生1～10条DNA条带，获得的RAPD谱带清晰并呈现多态性OPG15、OPH04两个引物扩增的RAPD谱带能将26种鹅膏菌完全区分开来，通过6个引物的RAPD分析获得的平均相似性系数表明种与种之间的相关系数在20―60%之间，平均链锁聚类分析可将26种鹅膏菌分为二大类，且一些具菌环和苞状菌托的种类聚在一起，与形态分类基本相吻合。
