Self-destructing chips have promising applications for securing data.This paper proposes a new concept of energetic diodes for the first time,which can be used for self-destructive chips.A simple two-step electrochemical deposition method is used to prepare ZnO/CuO/Al energetic diode,in which N-type ZnO and P-type CuO are constricted to a PN junction.This paper comprehensively discusses the material properties,morphology,semiconductor characteristics,and exploding performances of the energetic diode.Experimental results show that the energetic diode has typical rectification with a turn-on voltage of about 1.78 V and a reverse leakage current of about 3×10^(-4)A.When a constant voltage of 70 V loads to the energetic diode in the forward direction for about 0.14 s or 55 V loads in the reverse direction for about 0.17 s,the loaded power can excite the energetic diode exploding and the current rises to about100 A.Due to the unique performance of the energetic diode,it has a double function of rectification and explosion.The energetic diode can be used as a logic element in the normal chip to complete the regular operation,and it can release energy to destroy the chip accurately. 展开更多

This essay is going to read the different kinds of beings in The Lord of the Rings as different stages of man,and to analyze how they construct or destruct their selves respectively over power.The Lord of the Rings is read as a story about the self-construction and self-destruction of man,who begins to construct the sense of self from a very early stage in life,and becomes who he is in the continuous process of trying to identify himself with the image that keeps changing,of the frequently alternative construction and destruction of his self,and of intersubjectivity,the interrelation with other subjects. 展开更多

In order to decrease the unexploded submunition rate and reduce the harmfulness of u exploded submunition, a mechanical self-destruction and self-neutralization mechanism for submunition fuze is proposed in this paper. The definitions of the self-destruction and self-neutralization for submunition fuze are elaborated, and the action principle of the mechanical self-destruction and selfneutralization mechanism is also analyzed. A dynamic model is established with an analysis on centrifugal plate parts, and the feasibility of mechanism motion is also discussed. A virtual prototype of mechanism is formed, and the motion process simulation of the mechanism is performed through a dynamic analysis software ADAMS. The centrifugal experiment results validate that the mechanical self-destruction and self-neutralization mechanism can act reliably. 展开更多

This paper attempts to survey a minor character--the governess in Rebecca with the psychoanalytical theory, especially emphasizing her abnormal maternity towards Rebecca and trying to dig out its profound causes and its several abnormal characteristics. At last, the following conclusion is drawn: It is just this abnormal maternity that leads to the governess' self-destruction. 展开更多
