Gold Scorpionates Capture Ethylene ― Transition metal-ethylene complexes, known for nearly 200 years, were first made famous by Zeise's salt, K[PtCl3(C2H4)] H2O, a once-mysterious complex in which an ethylene molecule binds side-on to the platinum atom.

金蝎合物俘获乙烯――人们早在1827就制备了过渡金属烯烃复合物，最近因蔡斯盐，K[PtCl3(C2H4)] H2O，一种烯烃分子缠绕铂原子曾经很神奇的复合物，而首次名满天下。

It appearsthat condensed-phase 〓 would be a high energy fuel with high calorific value andan ideal high energy density material. It has the advantages as follows:(1)releasesenergy through self-dissociation mode;(2)does not need carrying another substancesupplying oxygen;(3)produces the final product 〓 molecule, which has very highstability and no environmental pollution.

通过对〓的密度、爆速、爆压和比冲的理论计算，可以得出〓是一种具有很高热值的高能燃料，是一种理想的高能量密度材料，它通过自身的分解释放能量，不需要另外携带供氧物质，并产生具有高稳定性的、对环境无污染的〓分子作功。

The concrete steps are: the lactic acid and small-molecule dicarboxylic acid react under the condition with the presence of the catalyst to directly polymerize the carboxyl-terminated lactic acid prepolymer; then the aliphatic polycarbonate diol and the catalyst are added; with the presence of the N2, the reaction is kept for 1 to 10 hours at the temperature of 150 to 200 Celsius system to get the poly lactic acid and polycarbonate copolymer of the low molecular weight; then the reaction is done in the twin-screw extruder at the temperature of 150 to 190 Celsius system to screw out the extension chain; finally the polylactic copolymer of the high molecular weight, toughness and heat resistance is made.

具体步骤是：乳酸和小分子二元酸在催化剂条件下反应直接缩聚合成羧基封端的乳酸预聚物，然后加入脂肪族的聚碳酸酯二元醇和催化剂，在N 2 气氛下，抽真空，在150～200℃温度下，反应1～10小时，得到低分子量聚乳酸/聚碳酸酯共聚物，然后在双螺杆挤出机中在140～190℃下，进行反应挤出扩链，最终得到高分子量的、韧性与耐热性较好的聚乳酸共聚物。

In fact only by considering benzene to be a resonance hybrid comprising at least a pair of cyclohexatriene resonance structures can we come at all close to an accurate picture of the real molecule.

事实上，只有把苯看作是至少由一对环己三烯共振结构（叫做 Kekule 结构）组成的共振杂化体，我们才能全面接近真实分子的精确图像。

METHODS Dinitrofluorobenzene was used to induce the contact dermatitis in mouse ear, rhIL-11 0.375-1.5 mgkg^(-1)d^(-1) sc for 10 d, the degree of skin inflammatory reaction was observed. At the same time, the serum level of tumor necrosis factor-α and interleukin-6(IL-6) was measured by radioimmunoassay; the serum level of nitrogen monoxidum was detected by biochemical method and the expression of intercellular adhesion molecule-1(ICAM-1) was detected by immunohistochemical method.

采用2，4-二硝基氟苯致小鼠耳部皮肤接触性皮炎试验模型，观察sc rhIL-11 0.375~1.5mgkg^(-1)d^(-1)，连续10d后皮肤炎症反应程度，同时采用放射免疫分析法测定血清中肿瘤坏死因子-α和白细胞介素-6(IL-6)的水平，采用生物化学检测法测定血清一氧化氮的水平，采用免疫组化法测定皮肤中细胞间粘附分子(ICAM-1)的表达。

He also suggested that the antioxidant activity of carotenoids might very likely be attributed to the oxygen levels around the molecule.

同时，他指出类胡萝卜素的抗氧化功能，很可能是取决於其分子周围的带氧水平。
