似环的

The silver - haired seed of the milkweed comes to roost there, frail as the halo rayed round a candle flame, a will-o'-the-wisp nimbus, or puff of cloud-stuff, tipping her queer candelabrum.

银色 有毛的乳草种子到达那里的鸟巢，虚弱似一根蜡烛火焰周围放射出的晕环，一个鬼火光轮，或烟云装饰她怪异的分枝烛台的尖端。

METHODS: Based on the antitumor activity and structural feature of 8-chloroadenosine and retinoic acid, modifications were made at positions 5′ and 8,substituted cinnamoyl and benzoyl groups were bound at 8 position through amido and ester bonds, sulfonation and nitrosation at 5′-OH and its direct chlorination were conducted.

对腺苷的8位和8-Cl-腺苷的糖环羟基进行了结构改造，以酰胺键和酯键在腺苷的8位连接了具共轭基团的肉桂酰基和苯甲酰基，得到腺苷的维甲类似物；对8-Cl-腺苷的5′-羟基进行了甲磺酰化，硝基化以及氯代反应，得到了它的衍生物。

Happy to doxycycline, tetracycline 36.63%, the highest sensitivity, all above 95%, secondly, to clarithromycin 90.98%, 82.71% azithromycin and roxithromycin 21.8%, to 24.82% ciprofloxacin 41.35% levofloxacin, etc, and 44.36% poor sensitivity conclusion: mycoplasm of common antibiotics have different levels of resistance to the early clinical, so for suspected cases for inspection in order to understand the drug susceptibility, thus, the reasonable use.

对强力霉素，美满霉素，四环素，交沙霉素的敏感性最高，都高达95%以上，第二为克拉霉素90.98%，阿奇霉素82.71%，而对罗红霉素21.8%，环丙沙星24.82%，氧氟沙星41.35%，司巴沙星44.36%等敏感性差结论：支原体对常用抗生素有不同程度的耐药性，因此临床上对尽早的对疑似病例进行送检以了解药药敏情况，从而合理，规范的用药。

ABSTRACT AIM: In order to find new type of antitumor compounds and study the contribution of hydroxyl groups on the sugar part to the antitumor activity of 8-Cl-adenosine, the retinoid analogs of adenosine and the derivatives of 8-Cl-adenosine were synthesized.

目的： 为寻找新型抗肿瘤化合物和探讨糖环羟基对8-Cl-腺苷的抗肿瘤活性的影响，合成了腺苷的维甲类似物和8-Cl-腺苷衍生物。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
