对名老中医药前辈学术思想与临证经验的继承与发展,是创新和发展中医药事业的一条重要途径。孙善德老药工从事中药炮制工作近50年,在中药炮制方面造诣精深。其自创立的沙参与桔梗、青果与西梅、蟅虫与黄蜂的鉴别方法,以及自制的新四制香附、龟甲、鳖甲、海狗肾等炮制要诀独具特色。在中药炮制传承人才紧缺的背景下,老药工炮制经验的传承显得极为必要,对研究新的炮制方法、拓宽炮制思路,显得意义非凡。 相似文献

Whereas in former times horses were reserved primarily for people involved in
agriculture, elite equestrians or the military, nowadays equestrian sport has become an
activity for people with a wide variety of backgrounds. However, as more and more people
become involved with equestrian sport today, the knowledge concerning animal husbandry in
general is diminishing due to an alienation from agricultural themes in modern societies.
As a consequence, this development affects both riding ability and the appraisal of
horses, especially with respect to the purchase of horses. In order to analyse which
factors influence purchase decisions in the horse market in conjunction with equestrian
experience, 739 horse riders were surveyed on their purchase behaviour in this study.
Using cluster analysis, a typology was generated that provides a differentiated picture of
the preferences of the various rider groups. Three clusters were distinguished: the
“amateurs”, the “experienced” and the “experts”. Taking personal horse riding proficiency
into account, it could be concluded that especially the “amateur” group required objective
criteria for the evaluation of a horse they are considering purchasing. Alongside
“measureable” qualities, such as previous showing success or the level of training of the
horse, also other attributes such as the simple handling of the horse should be taken into
consideration. As particularly the “amateur” group in equestrian sport is increasing in
numbers, it is therefore advisable when preparing a horse for sale to align oneself to the
needs of this customer segment in order to ensure an effective and targeted marketing of
horses. 相似文献

【目的】研究棉铃虫幼虫对棉酚和印楝素的味觉适应性行为,为棉铃虫的防治提供参考依据。【方法】采用叶碟法和味觉感受器切除法进行不同取食条件下棉铃虫5龄幼虫的取食选择行为试验。供试化合物为处理后终浓度为2mmol/L的棉酚和印楝素。【结果】正常人工饲料饲养的棉铃虫幼虫对棉酚和印楝素均十分敏感,取食对照叶碟量显著高于处理叶碟(P〈0.05);切除中栓锥感受器后棉铃虫幼虫取食含棉酚或含印楝素的叶蝶量与正常叶碟有显著差异(P〈0.05),而切除侧栓锥感受器后棉铃虫幼虫取食含棉酚或含印楝素的叶蝶量与正常叶碟差异不显著(P〉0.05);以含有低浓度取食抑制素的人工饲料饲养的棉铃虫幼虫对棉酚和印楝素不敏感,取食对照叶碟量与处理叶碟无显著差异(P〉0.05)。【结论】棉酚和印楝素是棉铃虫幼虫的取食抑制素,侧栓锥感受器中含有对棉酚和印楝素敏感的味觉神经元,不同取食经历的棉铃虫幼虫对棉酚和印楝素具有行为适应性。 相似文献

Pelvis size plays an important role to prevent dystocia in cattle caused by the foeto-maternal disproportion in commonly primiparous females. The reproducibility and repeatability are two important aspects for the reliability of the measurements to use in the selection of cattle for culling. Pelvic measures were taken with a Rice pelvimeter from 224 young cattle (180 females and 44 males) of four beef breeds in South Africa. One experienced and two inexperienced observers each measured pelvic height and width twice. The proportion measurements with a maximum difference of 0.5 cm within animal compared with the first measurement by the experienced observer are around 80% and by the inexperienced observers around 50% for pelvic height and around 60% for pelvic width. Breed and sex do not affect the reliability of pelvimetry by an experienced observer. Under- and overestimation of pelvis size were observed in inexperienced observers, which seems to be unrelated to breed and sex. 相似文献
