    摘要： The invention relates to a polymeric end-capping reagent for carbon dioxide-epoxide copolymers and a method for producing the same. The polymeric end-capping reagents provided by the invention are maleic anhydride copolymers and maleic anhydride terpolymers. The polymeric end-capping reagent for carbon dioxide-propylene oxide copolymers of the invention is produced by a radical solution copolymerization method, and has a number average molecular weight of Mn=4-6×104, a distribution index of 1.5-3.0. By using the polymeric end-capping reagent provided by the invention, the disadvantages of the small molecular end-capping reagent like volatilization during melting and precipitation on the melt surface during cooling, can be effectively overcome, moreover, the initial thermal decomposition temperatures of the carbon dioxide-propylene oxide copolymers end-capped with the polymeric end-capping reagents increase by about 30° C., as compared with that of the carbon dioxide-propylene oxide copolymer end-capped with “small molecular” maleic anhydride.

    摘要： The present invention relates to a process for preparing rare earth trichromatic phosphor, comprising the following steps: (1) providing precursors for at least one composition formula selected from the group consisting of CaBPO5:xEu:yTb, CaAlrB1-rPO5:xEu:yTb and Ca2B5O9Cl:xEu:yTb, wherein x=0.02–0.05 (mole ratio), y=0.001–0.01 (mole ratio) and r=0.5–0.8; (2) grinding and mixing the precursors; and (3) calcining the product obtained in step (2) at 800–1000° C. for 3–5 hours. According to the present process, only one matrix material and two rare earth reactive ions (Eu3+ and Tb3+) are required to synthesize rare earth trichromatic phosphor. That is to say, no reducing reagent is needed; and absence of reducing agent(s) reduces environmental pollution.

    摘要： A CDDP complex is formed by complexation of CDDP and a polymer having a structure of Formula (I). The CDDP complex has good biocompatibility and is degradable. A side chain of the polymer is grafted with polyethylene glycol, which gives the CDDP complex good dissolvability. When dissolved in an aqueous medium, the CDDP is protected by a hydrophilic polyethylene glycol chain segment and a hydrophobic amino acid chain segment, which can effectively avoid a sudden release of the CDDP due to the influence of the blood circulation system after intravenous injection, thus improving the stability of the CDDP complex. A carboxyl group contained in the CDDP complex has pH value sensitivity and tends to be deprotonated in a low pH environment, which is advantageous for promoting the release of a drug, and improving the efficiency of the drug.

    摘要翻译： 通过CDDP与具有式（I）结构的聚合物的络合形成CDDP复合物。 CDDP复合物具有良好的生物相容性，是可降解的。 聚合物的侧链用聚乙二醇接枝，这使得CDDP复合物具有良好的溶解性。 当溶解在水性介质中时，CDDP被亲水性聚乙二醇链段和疏水性氨基酸链段保护，这可以有效地避免由于静脉注射后血液循环系统的影响，CDDP突然释放，因此 提高CDDP复合物的稳定性。 CDDP复合物中所含的羧基具有pH值敏感性，并且在低pH环境中倾向于去质子化，这有利于促进药物的释放并提高药物的效率。
