In order to understand insertion/delation polymorphism of the angiotensin-converting enzyme gene in pilots,and to explore the relationship between ACE gene I/D polymorphism and the perfomance of the pilots,the polymerase chain reaction was used to determine the genotypes for an I/D polymorphism in intron 16 of the ACE gene in 118 pilots and 96 healthy subjects as controls.

为了解飞行员血管紧张素转换酶基因插入或缺失多态性情况，探讨ACE基因多态性与飞行员耐力可能的关系，用聚合酶链反应扩增技术检测118例飞行员和96例健康对照者的ACE基因I/D多态性。

At the same time,studying the depolarization reaction of D.desulf.has both anode and cathode depolarization reaction.

A general form of D-FOG has been proposed in order to lower the bias drift and several forms of that have been studied:(1) The Blake type in which a depolarizer is inserted between the polarizer and coil-coupler of D-FOG can suppress the intensity error but not change the magnitude order of the amplitude error.(2) The type with two Lyot depolarizers added in the ends of sensing coil can suppress efficiently the both errors.

为了减小D-FOG漂移，作者提出去偏陀螺的一般形式，并分析其中几种重要形式：（1）在偏振器与环分束器之间插入Lyot去偏器的Blake形式，可以有效地降低强度误差但不改变振幅误差的量级；（2）在传感环两端各插入一个去偏器可以有效地抑制这两种误差。

For the former, the binding energy is small and the size is large, with the typical example being the deuteron. For the later, the binding energy is large. d〓 is a typical example, whose binding energy is hundreds of MeV, Even taking into account the theoretical errors, it is still a stable dibaryon candidate.

前者的束缚能较小，半经相对较大，典型代表是氟核d；后者有较深的束缚势阱，最典型的例子是d*，它的束缚能达到数百MeV，即使考虑到理论模型的误差，它仍然可能是紧束缚的双重子态。
