The early instability theory still has some loose ends, however.How can cells with shifty chromosomes outcompete their stable counterparts? 不過(guò)，早期不穩定理論仍然還有一些未解決的問(wèn)題，譬如具有善變染色體的細胞如何勝過(guò)其具有穩定染色體的對手？
The stiffness analysis was investigated with the geometric relations of deployment and stowage.And the local and whole stability analyses were also studied with stability theory. 根據展開(kāi)和收攏幾何特性關(guān)系，對其剛度特性進(jìn)行了分析，并依據彈性穩定理論，對該展開(kāi)機構進(jìn)行了局部和整體穩定性分析。
