We also show that not all WSC designs can form annular jets, only annularly initiated WSC, which also fulfils the "Internal-External Liners Equal-Impulse" criterion, has the capability to form annular jet.

本文也表明并不是所有的W型聚能装药都能够形成环形射流，只有在环形起爆方式下，根据内外罩等冲量方案设计的W型聚能装药才能形成环形射流。

In th is paper, w e p ropo se a cert ificateless ring signature scheme, based on the bilinear pairings, w h ich p rovides uncondit ional anonym ity, and p rove th is scheme is existent ially un fo rgeable under adap t ive cho se2message at tack s, in the random o raclemodel, assum ing that the computat ionalD iffie2Hellman p roblem is hard to so lve.

摘 要 在这篇文章里，我们用双线性对构造了一种无证书的环签名方案，并证明它是无条件匿名的，且在随机预言模型中，计算性D iffie2Hellman 问题是难解的，我们方案在适应性选择消息攻击下是存在性不可伪造的，它的安全性比在基于身份的公钥密码体制下高。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
