However, the thermal stability of metallic coordination polymer hardly enhanced in comparison with the polymer never coordinated transitional metallic ions. The reason might be that the energy of coordinate bond formed between metallic ion and polymer was trival in comparison with that of covalent bond in polymer. It started with coordinate bond when the coordinate polymer decomposed under high temperature, so it engendered little for the thermal stability at high temperature.

An experiment is conducted to understand the effect of high molecular polymer fluid on the flow measurement using rotameter. In the experiment, the rotameters, which are composed of different floating elements with different shapes and materials in measuring tubes, are employed to measure the high molecular polymer fluid with viscosity from 1 MPa·s to 2 692 MPa·s. Through analyzing the impact of high molecular polymer fluid on the different rotameters, a general rule is obtained for measuring high polymer fluid using rotameter.

The produced water which was made by crude oil dehydration containing polymer, alkaline and surfactant, brought many technique problems in the water treatment process system, this made the polymer flooding and water flooding water treatment technologies difficult to suit to the disposal requirement of the special water. The developed experiment research indicated that: because of the surfactant, the semidiameter of the oil droplets in the ASP flooding is much smaller than that in polymer flooding, and the stability of the oil droplets is higher than that in polymer flooding, The viscosity and combine difficulty of the oil droplets increased, and all the changes of speciality resulted in the increased difficulty in the ASP flooding produced water disposal.

The growth inhibiting rate of T24 cell lines were detected by MTT methods, apoptosis of cells were detected by flow cytometry, the mechanism of apoptosis was analyzed by detecting the protein expression of Bcl-2, Bax, Caspase-9, Caspase-3 and cytoplastic protein Cytochrome C. 4 We injected live T24 cells into the subcutaneous space of nude mice and successfully built up the animal model of bladder carcinoma. The effect of CS-PAA-EPI polymer magnetic microspheres targeting chemotherapy was investigated by HE staining, TUNEL ,tumor weight and volume inhibition rate. Results: 1 TEM revealed that the CS-PAA polymer magnetic microspheres were regular spherical shape,the average diameter was 80nm in dry condition. By controlling the pH value of the medium,polymers had positive or negative zeta potential. VSM showed the CS-PAA polymer magnetic microspheres had superparamagnetic. The diameter of CS-PAA-EPI polymer magnetic microspheres were 200nm in solution by DLS examining,the embedding ratio was 20%,the EPI loading rate was 15%, which was higer than reported in other articles. 2 Raw eye observation found that the rat"s bladder of treatment group was brown color,which meaned the aggregation of iron particles, compared with the control group, iron stain found iron particles were assembled in rat"s bladder of the treatment group, the amount of iron particles in liver and spleen were less obviously.
