The synthetic technologies of three hindered amine light stabilizers were established, the reason for the insoluble side products formed in the production of polymerized hindered amine light stabilizers were studied, and a series of novel hindered amine light stabilizers with antibacterial properties were designed and synthesized in this present paper.1. Based on the investigation of the transesterification between dimethyl sebacate and 1,2,2,6,6-pentamethyl-4-piperinol, the synthetic technologies of Tinuvin292 and Tinuvin 765 were established. The two kinds of hindered amine light stabilizers were obtained in the yield of 93.3% and 92.4% respectively and qualified as the advanced level of the kindred overseas products.2. The synthetic technology of Tinuvin123 was studied and established.

The next year I did better still, for I spaded up all the land which I required, about a third of an acre, and I learned from the experience of both years, not being in the least awed by many celebrated works on husbandry, Arthur Young among the rest, that if one would live simply and eat only the crop which he raised, and raise no more than he ate, and not exchange it for an insufficient quantity of more luxurious and expensive things, he would need to cultivate only a few rods of ground, and that it would be cheaper to spade up that than to use oxen to plow it, and to select a fresh spot from time to time than to manure the old, and he could do all his necessary farm work as it were with his left hand at odd hours in the summer; and thus he would not be tied to an ox, or horse, or cow, or pig, as at present.

扬的著作在内。我发现一个人如果要简单地生活，只吃他自己收获的粮食，而且并不耕种得超过他的需要，也不无餍足地交换更奢侈、更昂贵的物品，那末他只要耕几平方杆的地就够了：用铲子比用牛耕又便宜得多；每次可更换一块新地，以免给旧地不断地施肥，而一切农场上的必要劳动，只要他夏天有空闲的时候略略做一做就够了；这样他就不会像日前的人们那样去和一头牛，或马，或母牛，或猪猡，捆绑在一起。

The person that has had SEO to operate experience is opposite certainly the friendship link of the website feels familiar, without giving thought to the website of the individual of big small business, in friendship the link exchanges a standard to go up, have the cognizance of a PageRank almost.

The nature of coupling between combustion and fracture are twofold in the convecting combustion process of crack cavity. On the macroscopic scale; the coupling appears as the energy and mass transforming between the solid phase of the cracked body the gas phase of the flow field. On the microscopic scale, the coupling induces the evolution of the microstructures, which leads to degradation of mechanical properties of solid materials.

从燃烧断裂耦合的内在形式来看，包括两大方面的内容：在宏观表象上，表现为在含能材料裂纹的对流燃烧过程中，固相裂纹体和对流燃烧流场之间的质能交换形式的热力耦合；在微细观运动方面，热和力的作用诱发固体材料微细观运动和组分、结构的变化，最终改变固体材料的宏观力学性能，表现为固体材料的热力损伤过程。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作，是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等)，但是不管是采用何种交叉操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的，采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

Centralized the iformation flow in detecting should satisfy afore-mentioned requirements, the haemal information network that builds a stability besides the requirement is exchanged with satisfying the real time of data outside, still should use the haemal information that accords with uniform standard to run software in order to assure centralized detect the unity of flow and can accuse, in addition, still should build regional integrated database on this foundation in order to assure the normative sex of data and consistency.

集中化检测中的信息流要满足上述要求，除了要求建立一个稳定的血液信息网络以满足数据的实时交换外，还应使用符合统一标准的血液信息管理软件以保证集中化检测流程的统一和可控，此外，在此基础上还应建立起区域性的综合数据库以保证数据的规范性和一致性。1.2国外信息保障方面的经验欧盟、美国、日本等发达国家都对信息技术给予了充分重视和大量投入，如美国采供血机构中的红十字会系统为实现全美地区的集中化检测，于1991—19。。。

Be in these places to add online station advertisement is special effectual, such, no matter you are hair theme post, still be the card of reply others, your autograph advertisement can follow your card and come out, going up somehow say, this is a kind of low cost, the promotion means of high income, the stationmaster that is equal with PR exchanges word of one later development to link, can take two visits amount through join already, in the meantime, also benefit is optimized at what the search ranks.

在这些地方加上网站广告是非常有效果的，这样，无论你是发主题帖，还是回复别人的帖子，你的签名广告都会随你的帖子而出来，在某种程度上说，这是一种低成本，高收益的推广方式，和PR等同的站长交换一下文字链接，既可以通过连接带两个访问量，同时，也利于搜索排名的优化。

The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...
