重復設備-
This process is repeated annually so that the number of light or dark ring indicate the age of that part of the plant
這樣的過程每年都重復，因此可以從深淺環形成的數目來推測樹木的年齡。 -
E. due to favorable condition of soil moisture, weak activity of wind and sand, and low inter - specific competition intensity resulting from repeated alternation between sand dunes and inter - dunes, the plant species richness and the plant species evenness are quite high in inter - dunes. f
由於丘間地水分條件較好，受風沙活動的影響較小，同時由於流動沙丘和丘間地的不斷更替降低了物種之間的競爭強度，就使丘間地具有較高的物種豐富度和物種均勻度。 -
The innovative ideas in this paper are that robust h control theory based on conventional ip controller is applied to the high - precision feed of a single axis, and the controlled plant is composed of ip velocity loop and two - order model of linear motor. a constraint condition on y in the problem of h2 / h is deduced from the frequency criterion of riccati equation, which makes the repeated computation on r simple. considering the two - loops control problem, the h state feedback controller based on ip controller as the inner controller is applied to satisfy the velocity performance of the system, and a pi controller, the external controller, is used to satisfy the position performance
本文的創新之處在於將傳統的ip速度控制器和直線電動機的二階模型作為一個廣義的被控對象，利用魯棒h _控制理論設計了一個h _狀態反饋控制器，以此解決高精度進給的控制問題，並在此基礎上研究了h _ 2 h _混合控制問題，結合h _代數riccati方程正定鎮定解存在的頻率判據，推出了一個控制器存在的約束條件，使以往須反復試探的，有了更進一步的約束范圍，簡化了計算。 -
A plant variety shall be deemed to be stable, where its significant characteristics remain unchanged after repeated propagation or, where the plant variety has a particular cycle of propagation, at the end of each such a cycle
一種植物品種將被視為穩定的如果它的重要特徵並未因重復的繁殖而改變者，或有繁殖周期的品種 -
