If I had to do it again, I would have had left the haul bag on the ledge with Wes. Then I would pendulum across with both the main line and the haul bag line. I'd pull both tight and tie them off at the belay stance. Then Wes would put the haul bag on his back and Tyrolean down to me -- using one of his jumars reversed as a brake.

假如我得再做一次，我会把拖包及Wes放在那里，然后我摆荡横渡主线及拖拉线，再将他们从确保站立处拉上来，然后Wes把拖包放在背上再Tyrolean下到我这里，用他其中一个犹玛制动。

A good example of this is Umberto Eco's novel Foucault's Pendulum, in which a group of friends program a computer to "write" a book about secret hidden knowledge.

With three displacement sensors, an approximate algorithm derived from vector product was given to measure the pendulum angle of quasi-taper swinging movement.

借助3个位移传感器，利用矢量积推导出一种近似算法，实现了准圆锥摆运动中摆角的测量。

For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum. The surface descriptions of velamen were conducted for D. fimbriatum and D. aurantiacum var. denneanum which are similar in characters of cross section.

方法利用形态组织学方法，对茎多肉质的束花石斛Dendrobium chrysanthum及其易混的玫瑰石斛D.crepidatum、报春石斛D.primulinum、重唇石斛D.hercoglossum、晶帽石斛D.crystallium；茎粗硬的流苏石斛D.fimbriatum及其易混的叠鞘石斛D.aurantiacumvar.denneanum；茎节或节间肿胀的棒节石斛D.findlayanum、杯鞘石斛D.gratiosissimum、肿节石斛D.pendulum和大苞鞘石斛D.wardianum共11种药用石斛根进行显微结构研究；对根横切面结构相似的流苏石斛和叠鞘石斛，配合进行了根被表面制片观察。
