D limonene was distributed among the culture flasks (200 mg/L). The flasks were incubated at 28oC on a rotary shaker (r/min=120) for 5 days. On completion, the culture broth were successively extracted with EtOAc. The extract was quantitatively measured by gas chromatography mass spectrometry analysis, The results showed that biocatalytic reactions were comprised of oxidation, including hydroxylation and ketonization which occurred at different positions of the D limonene, as well as hydrogenation, hydrolyzation, esterification and cyclic cleavage. These bacteria strains possess the distinctive biocatalytic capacities towards the D limonene. A series of terpenoids, including sesqui , di and tri terpernoids were also observed,which was accounted for D limonene had influence on the metabolites of marine bacteria.

以2216E为培养基，添加200mg/L的柠檬烯，在28℃，以120 r/min摇瓶培养5 d，用乙酸乙酯提取培养液，经GC MS分析其转化产物，结果显示，这些细菌能在柠檬烯的不同位置进行羟基化、羰基化等，并伴随有还原、水解、酯化、开环等反应，但转化能力和转化程度不同；在产物中，还检测到系列结构不同的其它萜类：包括倍半萜、二萜以及三萜等，这些萜类化合物的产生跟柠檬烯的加入有关，说明柠檬烯能影响细菌代谢产物的产生。

A novel kind of oligomer PPV derivative containing oxadiazole in the main chain was synthesized according Heck reaction, efficiency of single layer OPPV device was about five time higher comparing with single layer PPV device, which was attributed to the improved, balance of carrier injection and transportation.

三、利用Heck反应合成了PPV主链上含有恶二唑基团的可溶性低聚物OPPV，OPPV的单层器件的效率较单层PPV器件的效率提高5-10倍，证明了单层器件亮度和效率的提高是载流子平衡注入和传输的结果。

82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.

轴向进料蒸发室进口管侧上方有强烈的循环流存在，循环流流量为进口流量的1.48～1.82倍；循环流下部流速分布较均匀，出口区流速在低Re时为抛物线分布，高Re时接近活塞流；强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发，而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发，对蒸发操作十分有利；蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。

Results:The cell aggregations had differences in shape as well as size, flavone content, enzyme activities, growth speed and so forth. The flavone content of the smallest cell aggregation was approximately twice compared to the larger ones, and its malonaldehyde content, the phenylalanine ammonialyase and peroxide enzyme activities and recultivate curve presented the same change tendency.

结果：不同的细胞聚集体在形态大小、黄酮含量、酶的活性、生长速度等方面均存在着差异，其中颗粒最小的细胞聚集体黄酮含量约为颗粒较大的细胞聚集体的2倍，并且其丙二醛含量、苯丙氨酸解氨酶及过氧化物酶的活性及再培养曲线均具有相同的变化趋势。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

Because of the high magnification camera, we have to extract the laser streak from the obtained images fist, then we can get the line position of laser streak by using Otsu's method , morphology, skeletonization and Hough transform from the images of inspecting object. The system shows a good performance of getting only 5% error to the reconstructed surface of the standard board.

本系统采用放大倍率较大的镜头，因此在取像之后，必须先做雷射条纹形状的萃取，再运用Otsu演算法做二值化运算，搭配型态学影像处理，骨架化与Hough转换，计算雷射线的相隔距离，再透过前述的公式转换待测物体的厚度值。

The results showed that both sporophores and stromata of Cordyceps militaris had high content of polysaccharide. And polysaccharide content in stromata was 2-4 times higher than that in sporophores. CMPS could decrease the AST, ALT and MDA levels, and restore GSH-Px content and cell viability remarkably in supernatant of cultured hepatocytes injured by CCl4 induction.

结果表明：蛹虫草的子实体和基质都含有丰富的多糖，其中基质中的多糖含量最高，约为子实体的2~4倍；CMPS可明显降低由CCl4诱导的损伤肝细胞培养上清液中谷草转氨酶、谷丙转氨酶的活性水平和丙二醛的含量水平，显著提高由CCl4诱导的损伤肝细胞培养上清液中谷胱甘肽过氧化物酶活性和诱导损伤肝细胞的存活率。

This separates the magnetosphere's two main compartments: the crown, a round projection that stretches sunwards by about five times the diameter of the Earth, and the tail, which is shaped as its name suggests and runs far into space on the Earth's night time side.

这样也就把磁气圈两个主要部分就被分离开来：一为首部－圆形的凸出部分朝着太阳伸出5倍地球直径的距离；二是尾部－它的形状就像一条尾巴并在地球夜晚时的那一面伸向宇宙空间。

Methods:106 patients were randomly into two group treated with laser,66 patients were treated with Ultrapuilse 5000c CO 2 laser and 40 patients treated with potasium titanyl phosphatelaser,and the clinical effect were evaluated.
