The energy absorbed by the chlorophyll molecules of the unstable autumn leaf is not immediately channelled into useful products and processes, as it would be in an intact summer leaf.
不稳定的秋叶叶绿素分子吸收的能量，不会像在完好的夏叶中吸收的能量那样立即传输到有用的产品和工艺流程中去。
Free radicals produced by many biochemical processes or toxic substances, such as chemicals, pesticides, heavy metals etc, are unstable molecules that have an electron missing.
阿自由基产生的许多生化过程或有毒物质，如化学品，农药，重金属等，都是不稳定的分子，有一个电子失踪。
Processes are found to be unstable or non-capable?
过程不稳定或过程能力不足；
For bulk materials, if historical data shows that similar processes are chronically unstable, and previous actions have been unable to achieve stability, corrective action plans may not be warranted.
对于散装材料，如果过去的数据表明类似的过程长期不稳定，且以前实施的措施不能使其达到稳定，则可以不必保证纠正措施计划。
A kind of predictive PID PPID controller for several types of unstable plus time delay processes is proposed.
针对几种不稳定滞后过程，给出一种预测PID控制器的结构形式。
Also, it is well known that it is difficult to get good closed-loop step responses for processes with resonances, integrators and unstable plant transfer functions.
众所周知，当一个过程具有共振态、积分电路及不稳定设备传递函数的特点时，同样很难得到较好的闭环步进回应。
It can be applied not only to plants with unknown or show time-varying parameters and delays, but also to unstable inverse processes.
它即可用于参数和时滞未知的或慢时变的受控对象，又可用于逆不稳定过程，并能消除控制器的振铃现象，应用范围大为拓广。
