Results showed that hypochromism and red, shifted KAE absorption spectra were observed in the presence of DNA, and that synchronous、 fluorescence of DNA-NR was quenched with addition of KAE, indicating that a strong competition for DNA binding between KAE and NR existed, in addition, the relative viscosity and the value of melting temperature of DNA increased in the presence of KAE.

结果表明：加入DNA后，山柰酚的吸收光谱呈现减色和红移现象；山柰酚的加入使得DNA-NR同步荧光强度猝灭，表明山票酚对NR与DNA的结合为竞争性抑制；山柰酚的加入使得DNA的粘度增大，热变性温度升高。

The cyclization of carbodiimides 2 and 6 with phenol or alcohol was studied and the results showed that the cyclization of carbodiimides 2 and 6 with phenol in the presence of solid potassium at room temperature to 40℃, the cyclization of carbodiimides 2 and 6 with alcohol should in the presence of RONa.

进一步研究了碳二亚胺2和6与酚和醇的成环反应，结果表明该碳二亚胺与酚反应在碱(固体K_2CO_3)催化条件下，室温或加热到40℃便可顺利关环，与醇反应需要用到更强的碱醇钠催化才可以顺利关环。

Methods: 458 postmenopausal endometrial polyps were all treated by transcervical recection of polyp,and diagnosed by pathology.The presence of ER,PR, Bcl-2 and Ki-67 were detected by immunohistochemical staining.Following up these cases, 160 cases recured in three months to three years after treatment.These recurrence were treated by large dose mifepristone.After three months, 55 cases remainder EP were detected by hysteroscopy and treated by TCRP,then detected the presence of above receptors in the same way.

绝经后子宫内膜息肉患者458例，均接受宫腔镜下子宫内膜息肉切除术，术后病理诊断均为子宫内膜息肉，并采用免疫组化法检测子宫内膜息肉中雌、孕激素受体及Ki-67、Bcl-2的表达；随访以上患者，术后3个月～3年复发160例，均予大剂量米非司酮口服治疗，3个月后行宫腔镜检查，有残余息肉者55例，再行TCRP，并采用免疫组化法检测子宫内膜息肉中雌、孕激素受体及Ki-67、Bcl-2的表达。

The experimental results show that in the presence of acetic anhydride, the L-tyrosine can be completely racemized and converted into DL-tyrosine both in NaOH aqueous solution and in acetic acid solvent, and moreover, in the presence of acetic anhydride

今讨论了在碱性水溶液中，L-酪氨酸、乙酸酐和NaOH三者摩尔比例对消旋过程的影响和在纯乙酸溶剂中，乙酸用量和L-酪氨酸与乙酸酐的摩尔比例与消旋温度对消旋过程的影响。结果表明在乙酸酐的作用下，L-酪氨酸在纯乙酸溶剂中的消旋具有消旋速度快，DL-酪氨酸收率高的优点。

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用，喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上，阻碍了反应物分子的吸附，从而对喹啉的HDN反应有强烈的抑制作用。

One of the best ways of noting the presence of head lice in your child is checking for the presence of nits.

的最佳途径之一的注意到在场的头虱在您的孩子是检查存在尼特。

From the physics point of view is the singing tone related to a long sustain, the presence of a strong fundamental, rapidly decaying overtones, presence of complex harmonics...?

从物理学的角度来看是音色与长期维持，存在一个强大的根本，迅速腐烂的色彩，存在复杂的谐波。。。

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。
