A practical approach for open - closed armature position of the press ' s high spot closed - armature mechanism was introduced 摘要介绍了一种实用的印刷机高点闭牙机构开闭牙位置的确定方法。
Due to the special control structure of nine - point controller , the adjustment of control method is easier than customary control system 九点控制器特殊的开闭环结构使其在控制非线性系统的时候具有结构上的优越性。
The major activity node is focused around the marine basin ( with an openable causeway ) for temporary exhibition of ships and small tourists crafts 主要的活动枢纽会集中在海港内湾(设有活动开闭的堤道) ，可用作暂时停泊展览船及小型观光船。
By using the matlab software to simulate , we can get the optimal control strategy . in addition , we design a dual - stabilizing controller of a time - delay system with uncertainty 另外还给出了一种使时滞不确定系统开闭环双稳定的鲁棒控制器的设计方法。
While transportation by river was flourishing , the bridge used to be raised and lowered every time ships came and went . but it completed its role as a drawbridge in 1970 水运一度繁荣时，胜哄桥曾被频繁开闭于船只往来之际，直到昭和45年( 1970 )才完成了其最终使命。
In this paper , the new approach , the parametric adaptive open - plus - closed - loop control , is proposed to deal with this kind of problem and the robustness is proved 为了解决这个问题，本文提出了一种新的控制方法? ?参数自适应开闭环控制，并证明了这种方法具有鲁棒性。
In the first fire - engines , a boy was constantly employed to open and shut alternately the communication between the boiler and the cylinder , according as the piston either ascended or descended 最初的蒸汽机，原需雇用一个儿童，按活塞的升降，不断开闭汽锅与汽筒间的通路。
Subsidiary cell ( accessory cell ) one of a number of specialized epidermal cells of a plant that are found adjacent to the guard cells , and may help in opening and closing the stomata 副卫细胞：是特化了的植物表皮细胞的一种，紧邻保卫细胞，在植物气孔的开闭过程中起一定作用。
It was proved that the method was simple and accurate , and resolved the difficult problem in calculating open - closed armature position for the press ' s high spot closed - odontoprisis mechanism 实例的应用结果表明：该方法计算简单、准确，有效解决了印刷机高点闭牙机构开闭牙位置计算难的问题。
The plantlets grew much better in terms of root development ; the root activities , photosynthesis , regulating stoma and transpiration of them were significantly enhanced 主要表现在：植株健壮且根系发达，有大量的侧根形成；植株的根系活力、光合作用、调节气孔开闭和控制蒸腾速率等方面显著提高。
