The quaint three-lobed leaves, shaped like a grebe's foot, were still small, and the flower-stocks, thick as corn in a field, were crowned with pyramids of buds, cream and rosy-red like the opening dropwort clusters, and at the lower end of the spikes were the full-blown singular, snow-white, cottony flowers－our strange ans beautiful water edelweiss.

在古朴的三波瓣叶，形如grebe的脚，仍然很小，花卉股票，厚厚的玉米在现场，被冠以与金字塔的芽，奶油和美丽的红色一样开放dropwort集群而在低端的尖峰被全部吹奇异，雪白的， cottony鲜花-我们奇怪答美丽的水edelweiss 。

An optical method of rotating fan blade shape and deformation measurement is proposed, which was based on Fourier transform profilometry and stroboscopic effect, and than is verified by experiment on a domestic electric fan.

提出了一种利用频闪光作为结构照明光源，基于傅里叶变换轮廓术对旋转叶片每个时刻的三维面形和变形量进行动态测量的光学方法。

Basal leaves 5--10; petiole 2--6 cm; blade ternate, or sometimes simple, pentagonal or broadly ovate in outline, 0.6--1.5 × 1--2.4 cm, thinly papery, subglabrous or abaxially puberulent; leaflets petiolulate, rhombic, 2- or 3-lobed or 2- or 3-partite, sometimes 1--2 × 3-sect and with ultimate segments lanceolate-linear; central lobe rhombic-obovate, 3-lobed or 3-partite.

基生叶5-10；叶柄2-6厘米；叶片三出，或者有时单，五边形的或宽卵形轮廓的， 0.6-1.5 * 1-2.4 厘米，薄纸质，近无毛或背面被微柔毛；小叶具小叶柄，菱形的，2或3裂或2或3 分裂的，有时1-2×3全裂并且具末回裂片的有时披针形线形的；中央裂片菱形倒卵形，3浅裂或分裂。

Leaves petiolate, sheath narrow; blade ternate-pinnate or pinnatisect, membranous; ultimate segments filiform to lanceolate.

叶具叶柄，鞘狭窄；叶片回三出羽状或羽状全裂，膜；末回裂片丝状的到披针形。

Basal leaves all ternate, leaflets 1 or 2 × 3-sect, ultimate segments lanceolate-linear

The short-day effect is recepted by theleaves of M.charantia seedling.The first pair of shield-shaped opposite leavesof balsam pear seedling are slow to short-day effect.while the third and forthpalm-shaped alternate leaves are most sensitive to the photoperiod.

苦瓜幼苗中对短日反应的感受部位是叶片，它的第一对盾形对生真叶对短日的反应比较迟钝，而第三、四片掌状的互生真叶对短日最为敏感。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
