For example, the basic angiosperm stem is vertical and elongated, but some cacti have swollen water - storing stems, while other xerophytic plants that have lost their leaves during the course of evolution have evolved flattened leaflike stems for photosynthesis, e. g. butcher ' s broom ( ruscus aculeatus )
例如被子植物的莖是垂直的，伸長的，但一些仙人掌具有膨大的能夠儲水的莖，另一些旱生植物在進化的過程中失去了葉子，但又發展為利用扁平葉狀的莖來進行光合作用（假葉樹） 。 -
The slurry is pumped under pressure into a vessel that is fitted with a stack of vertical leaves that serve as filter elements
過濾機葉片外表層用特殊結構的細濾網精製而成，中間夾有支撐網，過濾精度高 -
Then, taking into account the effect of the compression of the approach roadway and the differential slope of the bridge slab, the author analyzes the dynamic response of man - vehicle - road system when the vehicle approaches and leaves the bridge by means of laplace transform, the curve of man ' s acceleration versus time, the vertical force between the vehicle and road versus time, the man ' s maximum transient vibration value and the maximum force between the vehicle and road are got, and the program about the calculating progress above are edited. based on the analysis above, the influence on the maximum transient vibration value of some parameters about the vehicle and road such as the movement direction and speed and weight of the vehicle, the differential slope of the bridge slab and the length of the approach slab, are studied, and some conclusion are given
分上橋和下橋兩種情況，考慮車路耦合和橋面沉降坡差的影響，對車輛通過設和不設搭板的路橋過渡段時「人?車?路」系統的相互作用用拉普拉斯變換法進行了動力響應分析，得到了人的加速度及路面對車的垂直作用力隨時間的變化曲線、人的加速度最大瞬態振動值和路面對車的最大作用力，分析了車輛的行進方向、速度和載重，橋面沉降坡差和搭板長度等車和路各參數對計算結果的影響，並編制了相應的計算程序。 -
In vertical leaves, such as those of grasses, they may be equally distributed on both surfaces
