In this context, we propose a time deployment based, pairwise keymanagement scheme called TDBK. In TDBK, the network lifetime is divided intoseveral consecutive network deployment statuses which are separated by nodedeployment events. Each node to be deployed is assigned its key informationthrough a special two-tier key predistribution mechanism, and timely deletes theuseless part of the key information through the key elimination mechanism eachtime the pairwise key establishment is finished in terms of a new nodedeployment event.

在此背景下，我们提出了一种基于时间部署的对****管理方案(Time Deployment Based Keying，TDBK)，该方案将网络的生命周期分为多个连续的网络部署状态，相邻的部署状态之间通过节点部署事件分隔，每个节点通过特殊的两级****预分配机制来获得用于建立对****的****信息，随后通过****清除机制在每次节点部署事件发生时进行的对****建立过程完成后及时地删除其中无用的****信息。

Make signal be called binary system numeral to make for the make of binary system signal, the binary system make and is divided into a binary system to move key to control(2 ASK), the binary system Pin move key to control(2 FSK), the binary system mutually move key to control(2 PSK) with bad cent the binary system mutually move key to control(2 DPSK) etc. variety basic type, this topic main is numeral the frequency make and call Pin to move key to control.

调制信号为二进制信号的调制称为二进制数字调制，二进制调制又分为二进制幅移键控（2ASK）、二进制频移键控（2FSK）、二进制相移键控（2PSK）和差分二进制相移键控（2DPSK）等多种基本的类型，本课题主要是数字频率调制又称频移键控。

According to password which establishes, uses two pressed keys realizations password the input function, after the password input is correct, locks opens, if inputs three passwords are not correct, locking presses a key 3 seconds, simultaneously discovered reports to the police the sound, after has not pressed a key presses down 3 kinds, only then opens the pressed key locking function; Otherwise still had the pressed key in 3 seconds to press down, relocked presses a key 3 seconds time and reports to the police

根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警

In the part of empirical analysis of Chinese IPO first-day return, the difference between existing study and this study is that we use principal components analysis to extract from five factors to construct investors'sentiment index, add it to controled varibles, on which we examine the influence of offering mechanism on IPO first-day return. Moreover, we gather statistics and compare the IPO holding return for lockup period between fixed-price-class offering method and bookbuilding-class offering method, as well as price range between Chinese A-share market and Hongkong stock market, which prvide comprehensive evidence to appraise Chinese IPO bookbuilding mechanism. 2. Compare to the existing literatures which consider discount or allocation, incentive allocation and discount are considered at the same time in optimal mechanism design in this dissertation, and the offering bottom price is introduced to the price range. We investigate the relationship between price range and allocation quantity, and obtain the optimal price range and allocation strategy so that the advantages of independent allocation are reflected. On the other hand, the disadvantages of independent allocation are reflected in the manipulation in case of no restriction on IPO allocation. To distinguish from the existing literatures, bookbuilding mechanism is introduced to the model. We study the allocation strategy adopted by the underwriter in the pooling equilibrium of manipulation. In addition, we analyze the incentive compatibility conditions to which the existence of pooling equilibrium should satisfy and examine some factors'impact on the existence of manipulation.3. In bookbuilding without independent IPO allocation, Chinese realistic IPO background is considered and the condition of bookbuilding and fixed-price hybrid offering is added. Divide bookbuilding and fixed-price hybrid offering into sequential hybrid and simultaneous hybrid, and point out that the key points of subscription strategy in the two kinds of hybrid are different. Through modeling and simulation we obtain the impact of institutional investors'subscription strategy on bookbuilding without independent IPO allocation, which fill the gap in related research. Moreover, in the part of IPO bookbuilding with over-allotment option, the pricing strategy is divided into hot-IPO strategy and weak-IPO strategy. Take into account the procedure of Chinese IPO with over-allotment option, it presents how the underwriter determines the pricing strategy and what effect it brings to offering price and issue size through modeling and simulation. Therefore, it is instructive as a complement to existing literatures.
