安全性

They allow that the backend server could delegate the reader to identify the tag information. But the Fouladgar and Afifi's SiDES protocol will suffer from the replay attack, forgery attack, Denial-of-Service attack and fail to achieve the forward security. Although Lin's protocol uses timestamp to control the delegation, it does not keep forward security property under the same time frame.

在2007年，Fouladgar和Afifi首先提出了离线式SiDES协定，接著Lin也提出了TCD-RP协定，可让后端伺服器可以授权读取器辨识标签的资讯，但Fouladgar和Afifi的SiDES定理，会遭受重送攻击、伪造攻击、阻断服务攻击以及不具有向前安全性的特性；而Lin的协定虽然使用时戳来做授权的控制，但在相同的时间区段下运作，并不具有向前安全性的特性。

The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

为了明确杀蚜药剂对麦蚜的防治效果、适宜的防治时期、对生态环境安全性和粮食作物食品安全性的影响，对4.5%氯氰菊酯、40%氧化乐果、40%毒死蜱、3%啶虫脒、10%吡虫啉等9种防治麦蚜的药剂进行了筛选，发现各药剂对麦蚜的防效较好，喷药后7d防效均在90%以上。9种农药在喷施后的3d内，对麦蚜的主要天敌蚜茧蜂和瓢虫影响较大，两种天敌数量锐减，但到7d时各处理蚜茧蜂数量均有回升，其中不同剂型的吡虫啉、啶虫脒和鲁植顺克处理的蚜茧蜂数量同对照相差不大。

To address this problem, a new method of security analysis of QKD protocols is introduced. Based on the equivalence attack model of QKD protocols which is refered to Biham's proving, the protocol is divided into two parts: the body and the attack, then a Petri-net model of BB84 is obtained, and a security analysis is followed.

为了简化量子密码协议的安全性证明以及建立一种通用的证明方法，基于Petri 网提出一种量子密钥分配协议的形式化分析方法，根据Biham 的等效对称化攻击模型，将协议分为主体模型和攻击模型两部分，建立了BB84 协议的Petri 网模型，然后对模型进行安全性分析，分析结果表明， BB84协议是无条件安全的。

The anti-ischemia effect in myocardium of corydalis rhizoma is related to the direct protective effects on cardiomyocytes of its components, tetrahydropalmatine, dehydrocorydaline, berberine and palmatine, amomg which tetrahydropalmatine and dehydrocorydaline are the most important, the former with high safety and low efficacy, while the latter with low safety and high efficacy. And the direct protective effects on cardiomyocytes of these four components, may be attained through mechanisms other than anti-peroxidation.

延胡索抗心肌缺血损伤的作用与其成分延胡索乙素、脱氢紫堇碱、黄连素和巴马汀对心肌细胞的直接保护能力有关；其中，延胡索乙素和脱氢紫堇碱的作用最为重要，前者安全性高，但效能较低，后者安全性低，而效能较高；而这4个单体的保护作用可能是通过抗氧化损伤之外的机制达到的。
