To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.

为了开发新的合成方法，研究了苯并咪唑盐与各种亲核试剂（活泼芳环与杂原子亲核试剂）的反应，发现苯并咪唑盐不与活泼芳环及杂原子亲核试剂发生2位加成反应；在与体积较大的位阻型N亲核试剂邻苯二甲酚亚胺反应时，未得到亲核试剂与极化的C＝N的加成产物，而是得到N烷基化的邻苯二甲酰亚胺，进一步研究表明，苯并咪唑盐将1（3）位N上的烷基转移给了邻苯二甲酰亚胺，并讨论了其反应机理和取代基，溶剂效应。

The results indicate that the pillaring process and crystal growing of anatase can be more easily realized by increasing the acid-base ratio of pillaring agents, raising the pillaring temperature and adding proper quantities of alkali. The calcination of Ti-pillared precursor brings the growth of TiO2 grain, at the same time the layer distance is declined. In order to obtain ideal products, the right pillaring conditions are: the acid-base ratio of pillaring agents of 13, pillaring temperature of 65 ℃ and the volume of alkali (2 mol/L) in pillaring liquid of 6 mL.

结果表明：在一定范围内增大柱撑剂酸碱比、提高柱撑温度以及加入适量碱，有利于插层复合反应的进行和锐钛晶型的生长；柱撑前驱物焙烧后TiO2晶粒长大，同时焙烧引起的脱水导致膨润土层间距的下降；为获得较理想的产物，合适的柱化条件为：柱撑剂酸碱比 n n (HNO3)为13、柱撑温度65 ℃和柱撑液加碱量为(2 mol/L NaOH) 6 mL。

The scheme adopts a multi-agent system and a threshold secret share technology, in which the secret information and the shares are carried by many different agents, adopts D-H key exchange technology to encrypt intermediate result to hide real intention of agent, to protect the privacy of agents and to enhance the reliability and the fault-tolerance capability of the mobile agent system. A mobile agent with limited authorization can sign a message on behalf of a user at far-end without divulging the user s private key. In order to avoid rebuilder attack the time-stampe mechanism is adopted.

运用信息加密和身份认证技术，实现了移动Agent和Agent平台间双向身份认证，有效地防止了恶意Agent对Agent平台的攻击或越权访问以及恶意Agent平台对Agent的攻击；引入远端可信任的代理平台作为数据处理平台，采用多代理系统和门限秘密共享技术，将加密信息和密钥由多

A novel approach that uses distributed active agents to extract the basic reflectional symmetry axes in gray images is presented in this paper. It detects, groups and links the prominent local symmetry axes by simulating the behaviors of the agents such as inhabit, evolve, diffusion and death in local image environme.

提出一种利用分布式主动智能体提取灰度图像中的基本反射对称轴的新方法，它通过对智能体在局部图像环境中定居、发展以及迁徙和死亡等行为的模拟来检测、编组和连接显著的局部对称轴。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。

Change to a shampoo with no conditioning agents (such as protein, silicone, quaternium, or polyquaternium) or thickening agents (such as cetyl alcohol or stearyl alcohol), and use only the smallest amount of conditioner on the ends.

因此绝对没有听说过那个洗发水不好是因为其中十六，十八醇加了过多的缘故。因为就象你不可能在一个稳定的体系中加很多营养成分一样，加到一定的量就起不到好的效果了而且会破坏整个产品的稳定性，不能稳定的保存到保质期限啊。
