结合长期风速记录,利用Gumbel分布计算设计风速极值,并采用Monte-Carlo法模拟台风作用,推导了风速和风向的联合概率分布。利用Lawson和Penwarden舒适度判别准则,分析风洞试验中Irwin探头的实测风速结果,评估了超高层建筑行人高度风环境舒适度并检验了风环境改善措施效果。结果表明,风气候分析对评估行人高度风环境舒适度有重要影响,部分重要区域（北侧裙房入口、三层室外阳台、东南连桥、西北裙房屋顶等）不满足舒适度要求。采取防风减风措施后,改善了大部分区域的舒适度,而西北裙房屋顶仍不满足舒适度要求,需要调整功能布局。 相似文献

本论文分析了低层大气急流的季节变化.原始数据是美国的编号为03937的站点2002-2004年的数据,笔者对数据中经向风和纬向风这两个参数进行处理.通过对其拟合处理,运用IDL软件编程输出图形,发现低层大气急流的季节变化规律,即经向风的风速随着高度的变化幅度小,纬向风的风速随着高度的升高变化幅度比较大,春冬季急流最大,而夏季急流最小. 相似文献

Having mixed extremely various patterns of achenes for a long time in
the genus Lactuca L., especially showed in the classification of it on the mainland of Asia,
Lactuca L., the primary unnatural genus, becomes more nuclear in its limit. The present
paper makes a revision to attempt providing a clear cline between Lactuca L. and its relative
genera.
On my opinion, only plants, represented by Lactuca sativa L., which have ovoid capitu-
lum during its fruiting, numerous (7-25), yellow ligular florets and longitudinal 1-10 ribs
or striae on each side of achenes, acute into filiform beak at its apex, should be defined as
Lactuca L.
In view of the present concept of Lactuca L., another group of plants, embodied by
Lactuca indica L., having its broadening, thin winged-margin of, 1-3 striae on each side of
achenes, black, dorsi-ventral compressed, acute into thick and short beak at its apex, evident-
ly, should not be placed into Lactuca L., but be regarded as genus, i.e. Pterocypsela Shih,
gen. nov. Pterocypsela Shih distributes in Eastern and southern Asia, where Lactuca L. does
not occur. In China there is all of species, seven species, of Pterocypsela Shih. They are P.
raddeana (Maxim.) Shih, P. indica (L.) Shih, P. elata (Hemsl.) Shih P. lacciniata (Houtt.)
Shih, P. triangulata (Maxim.) Shih, P. sonchus (Lévl.) Shih and P. formosana (Maxim.)
Shih, But in Mediterranean regions and Middle and Western Asia mainly distributes Lactu-
ca L., in which there are only seven species from western China, Xijiang autonomic district.
They are L. dolichophylla Kitam., L. sativa L., L. altaica Fisch. et Mey., L. serriola Torner,
L. dissecta Don, L. auriculata DC. and L. undulata Ledb.
With the combination of violet-purple ligular florets non-ovoid capitulum during its
fruiting, a little thick achenes, acuminate into longer. or short beak at its apex and 4-6 ribs
on each side of it, Mulgedium tataricum (L.) DC. is evidently different from Lactuca sativa L.
with combination of ovoid capitulum during its fruiting, yellow ligular florets and compres-
sed achenes, acute into filiform beak at its apex. There seems to be no point in refusing Mu-
lgedium Cass. as a genus. Strictly speak, Mulgedium Cass. seems to be reminiscent of Para-
prenanthes Chang (see bellow) without beak at the apex of its achenes. In Hengduan moun-
tains and mountain range of Himalayas M. tataricum (L.) DC. discoveries its relative par-
tners. They are M. bracteatum (Mook. f. ex. C. B. Clarke) Shih, M. lessertianum (Wall. ex
C. B. Clarke) DC., M. monocephalum (Chang) Shih, M. umbrosum (Dunn) Shih, M. meridi-
onale Shih and M. polypodifolium (Franch.) Shih.
Having broadering and thickening margin and 4-7 striae on each side of achenes, grey,
dorsi-ventral compressed, truncate and beakless at its apex, Lactuca sibirica (L.) Benth. ex
Maxim. (Sonchus sibiricus L.) is not only different from Lactuca sativa L. with the combi-
nation of yellow ligular florets and filiform beak at apex of its achenes, but also from the
genus Mulgedium Cass. with beak at apex of its achenes. Therefore, Lagedium Sojak, establi-
shed by J. Sojak (1961), should be restored. It should be point out that Lagedium Sojak is
monotypic genus excluding Mulgedium tataricum (L.) DC. with beak at the apex of its ache-
nes, non-marginated. Lagedium Sojak widely distributes in temperate and frigid zone of
northern hemisphere. In our country, Lagedium sibiricum (L.) Sojak, sole species of the ge-
nus, restricts its northeast region.
Paraprenanthes Chang, the new genus, established by Ch. Ch. Chang (1950) based on La-
ctuca sororia Miq. and Lactuca yunnanensis Franch. seems to be a distinct genus. This ge-
nus is characterized by 4-6 ribs on each side of achenes, black, fusiform, a little thick and
beakless at its apex. Besides above-mentioned two species, assigned by Chang, in forest of tro-
pic and subtropic zones on the mainland of Asia there are many species with same structure
in achenes like L. sororia Miq. and L. yunnanensis Franch. The genus Paraprenanthes Chang
seems to be reminiscants of Mulgedium Cass. and Lagedium Sojak, but differs from the former
in its beakless achenes, from the later in its non-marginated achenes and 4-6 ribs on each
side of it. In our country, there are all species of the genus known in the tropic and sub-
tropic zones on the mainland of Asia. They are P. sororia (Miq.) Shih, P. yunnanensis (Fra-
nch.) Shih, P. longiloba Ling et Shih, sp. nov., P. heptontha Shih et D. J. Liou, sp. nov., P.
prenanthoides (Hemsl.) Shih, P. pilipes (Migo) Shih, P. thirionii (Lévl.) Shih, P. sylvicola
Shih., sp. nov., P. multiformis Shih, sp. nov., P. auriculiformis Shih, sp. nov. and P. sagitti-
formis Shih, sp. nov. 相似文献

Peristylus is a genus of over 60 species, mainly distributed in the Old World
tropics, with many species extending northwards to central China. In the present paper, the
taxa of the genus hitherto recorded in China are taxonomically and phytogeographically dis-
cussed and revised, and, as a result, 20 species are recognized, including one new species, P.
jinchuanicus K. Y. Lang, and four new combinations, P. bulleyi (Rolfe) K. Y. Lang, P. for-
restii (Schltr.) K. Y. Lang, P. longiracemus (Fukuyama) K. Y. Lang and P. neotineoides
(Ames et Schltr.) K. Y. Lang. A full list of synonyms is given, a key to the species is pro-
vided and the distribution areas in China of all the taxa are mapped. 相似文献
