近年来,随着农村经济的发展,农民的生活居住环境得到了很大的改善,许多农家修建了漂亮的二层小楼,在楼顶修建了自来水塔,用上了自来水,时常要给水塔抽水,成了农家的一件日常工作,但时间久了,也难免感到挂心。为了解决这一问题,我利用简单机械和力学原理,设计了一种简易的自控抽水开关,现简介如下,供参考。1.电线2.铁片静触点3.带铁片磁铁4.铁片触点5.开关盒6.杠杆支点7.杠杆8.连杆9.小孔10.细绳11.浮力瓶12.小石子13.水塔14.进水管一、结构简图二、工作原理1.当水面下降时,浮力瓶随着下降,当水面降到某一高度,浮力瓶不再受到水的浮力,杠杆在… 相似文献

中药贝母名实考订 总被引:1,自引:0,他引:1
Bei-mu (贝母), the bulbs of some fritillaries, is one of the most popular drugs
used in China ever since the ancient times. It is prescribed principally in coughs
and fevers. In recent years, although much chemical and pharmaceutical investiga-
tions of this drug have been made, its botanical origin remains confused. Several
types of commercial drugs Bei-mu, for instance, were incorrectly considered by some
authers as being derived from the bolbs of Fritillaria roylei Hook., a species of Kashmir
and Kumaon, not yet found in China. In the present paper, the writers attempt to
give a revision of the genus Fritillaria of China as well as of commercial drugs sold
on the chinese market under the name of Bei-mu, based on both plant and drug speci-
mens collected from 18 provinces and autonomous regions.
As a result of our study, twenty species, including two varieties, of Fritillaria of
China are recognized, of which four, F. crassicaulis S. C. Chen, F. omeiensis S. C.
Chen, F. unibracteata Hsiao et K. C. Hsia and F. hupehensis Hsiao et K. C. Hsia,
and one variety, P. thunbergii Miq. var. chekiangensis Hsiao et K. C. Hsia, are de-
scribed as new. They all, except two species, viz. F. maximowiczii Freyn and F.
davidii Franch., are known to possess medicinal value, from which different kinds of
commercial drugs Bei-mu are derived. These drugs are usually named for the places
where they come from. The first, called Zhe-bei (浙贝), F. thunbergii Miq., is obtained
from Chekiang and Kiangsu, the second, called Ping-bei (平贝), F. ussuriensis Maxim.,
from northeastern China, the third, called Lu-bei (炉贝), F. delavayi Franch., from
southwestern China, the fourth, called Chuan-bei (川贝), including F. cirrhosa D. Don,
F. unibracteata Hsiao et K. C. Hsia, F. przewalskii Maxim. etc., from Szechuan and
its neighbouring provinces, and the fifth, called Yi-bei (伊贝), including F. pallidiflora
Schrenk, F. karelinii (Fisch.) Baker, F. walujewii Rgl. etc., from Sinkiang. Occasio-
nally, the tubers of Bolbostemma paniculatum (Maxim.) Franquet, the corms of Iphi-
genia indica Kunth and the bulbs of Lloydia tibetica Baker and Cyanotis vaga
(Lour.) Roem. et Schult. are also called Bei-mu in some local drug markets. They
are different not only in medicinal property but also in appearance from our tradi-
tional genuine commercial drugs Bei-mu as stated above. They are apparently adul-
terants.
Detailed accounts about the plants and drugs are given in the text. There are also
provided keys and illustrations which, we believe, will afford facilities for identifica-
tion. 相似文献

Paeonia suffruticosa Andrews subsp. spontanea (Rehder) S. G. Haw et L. A.
Lauener ( =P. spontanea = P. jishanensis) has been considered as the wild form of widely
cultivated P. suffruticosa. However, the subspecies differs from the cultivated one in
shape, division and indumentum of leaves and reproductive biology. As a result of extensive
field work, a form with two individuals in Yinping Shan, Caohu, Anhui, and Songxian,
Henan, are found to be extremely similar to P. suffruticosa, but apparently different from
P. jishanensis. The form is considered to be the wild one of P. suffruticosa and described as new: P. suffruticosa subsp, yinpingmudan Hong, K. Y. Pan et Z. W. Xie. 相似文献
