In the field of yarn dyeing, the most generally employed method is a type of package dyeing which uses a package of cheese stacked on a spindle made of a perforated tube. spindles up to now, have been designed without considering the characteristics of dyeing liquid, focusing only on the geometric configuration which cause many problems such as lack of level dyeing. To improve the level dyeing and find the appropriate spindle configuration for the most effective dyeing process, this study examines the spindle flow-field in detail, using a computational method. Flow characteristics inside the spindle have been investigated with varying in porosity, porous diameter and the velocity of the flow. The results show that the total pressure of the flow through the spindle is used to overcome body force. The characteristics of the flow from the porous spindle could also be observed. Based on the results from this study, an effective spindle configuration for level-dyeing has been proposed.

作者用液体贮存法（在细胞增殖前液体保存４８ｈ），来研究氯化甲基汞（ＭＭＣ）所产生的细胞毒性或染色体损伤后的修复，从而探讨其作用特点。实验证明，ＭＭＣ处理Ｇ_０期人淋巴细胞后所诱发的染色体畸变、染色单体畸变和非整倍体等恒定性损伤，液体贮存对其修复无作用，表明ＭＭＣ的作用特点与Ｘ线相仿，能产生包括结构畸变和数量畸变在内的持久损伤。

Caldesia parnassifolia (Bassi ex Linn.) Parl. in China has declined in number in r ecent years and is increasingly faced with the risk of extirpation arising from anthropogenic changes associated with rapid urbanization and expansion of both agriculture and infrastructure. To aid in provision of the data needed for effective conservation of the species, studies on the habitat, pollination ecology, and breeding system of C. parnassifolia were carried out on natural populations occurring in southeastern China. Flowering in the study populations extended for more than eighty days beginning in early summer. Floral anthesis occurred in the morning hours and proceeded rapidly, lasting about 45 min. Flowers lasted ca. 8 h. Caldesia parnassifolia is self\|compatible; however autogamy resulted in lower seed set than geitonogamy and xenogamy as well as free pollination. The data on pollen/ ovule (P∶O) ratio is consistent with a partially selfing and outcrossing mating system. Interpopulational crosses yielded similar seed set to within\|population crosses. Agamospermy did not occur in the study populations. Propagation is achieved through seeds as well as through turions which commonly occur in the inflorescences. Flies (Insecta; Diptera) were the most frequent visitors to the flowers of C. parnassifolia; however bees (Insecta; hymenoptera) composed a larger proportion of effective pollinators. The syrphidae species sphaerophoria indiana (Bigot) presents evidence of oligolectic foraging behavior. Recommendations are made on the immediate steps necessary for conservation of Caldesia species in China.

目的比较应用双腔支气管导管及Univent管行单肺通气的安全性,及对术后声音嘶哑、咽喉痛的影响。方法选择需单肺通气择期行食管癌根治术的患者100例。随机分为Univent管组和双腔支气管组,每组50例。Univent管组通过插Univent管实现单肺通气,双腔支气管组通过插入双腔支气管导管实现单肺通气。所有气管插管均由同一个熟练的麻醉医生完成。主要观察指标:①完成插管所用时间;②单肺通气时肺萎陷质量和外科术野暴露程度;③治疗后24、48、72h采用标准化问题对声音嘶哑和咽喉痛进行评估。结果①双腔支气管组的插管时间明显较Univent管组长(P0.05);③双腔支气管组术后声音嘶哑及咽喉疼痛的发生率较Univent管组显著升高(P<0.05)。两组患者均未发生如支气管断裂等严重并发症。结论双腔支气管导管和Univent管在食管癌根治术患者行单肺通气中的应用均安全有效,应用Univent管可减少患者术后声音嘶哑及咽喉疼痛的发生率,在适应证范围内可以首先选用Univent管。
