The accurate control of the work pieces temperature in vacuum annealing furnace is a typical nonlinear large time delay and crosscoupling complicated problem.
而在真空退火的生产过程中，退火工件温度的精确控制是一个典型的非线性、大时滞、强耦合的复杂控制问题。

The trio developed a process known as palladium-catalysed crosscoupling, a means of knitting carbon atoms together so that they form a stable "skeleton" for organic molecules.
As this kind of microstrip hairpin filter does not require crosscoupling between the non-adjacent resonators of the filter to obtain transmission zero, the design procedure of the filter is simple.
