Pyrolysis characteristics of simulative medical waste, which was composed of polymerized propylene, face paper, gauze, pledget, one-off respirator and medical latex glove proportionally, were studied at the atmosphere of nitrogen on cannular electric furnace.

在管式电阻炉上对由聚丙烯、面巾纸、纱布、医用脱脂棉、一次性口罩、医用乳胶手套等按一定比例组成的模拟医疗废物在氮气气氛进行了热解研究。

In order to study the expression and functional characteristics of dehydrin gene during different growth, and make the polycolonal antibody, using wheat plumelet under the water deficit condition as experiment material, and its total RNA was extracted. The target dehydrin gene through RT-PCR was got, connect to the cloning vector PUCM-T, recombination expression plasmid PET-32a-wzy1-1 was constructed according to recombination of cloned vector PUCM-T-WZY1-1 of wheat dehydrin gene in this experiment.

为研究小麦在不同时期脱水素基因的表达情况和生物学功能及抗体制备，以小麦幼芽为材料，经干旱胁迫处理后，提取总RNA，通过RT-PCR得到小麦类脱水素基因片段(WZY1-1)，再连接至克隆载体PUCM-T，并成功构建重组表达质粒PET-32a-wzy1-1，将阳性重组质粒转化于受体菌BL21(DE3)感受态细胞中，经IPTG诱导表达，进行表达产物的聚丙烯酰胺凝胶电泳检测。

In the case of polyolefins, such as polypropylene, the problem is particularly severe since this polymer has a surface void of polar groups.

如在聚烯烃中，如聚丙烯，的问题，尤其是严重的，因为这种聚合物表面无效极性基团。

Polypropylene its superior performance has been widely applied, but their smaller polar surface, resulting in surface water and surface bonding of poor has greatly limited the scope of its application development.

聚丙烯以其优越的性能已经得到了广泛应用，但是其表面极性较小，导致表面亲水性和表面粘结性较差，极大地限制了其应用范围的拓展。

Polypropylene is used for standard clamps and Polyamide or Aluminum for special applications.

聚丙烯是标准夹具和聚酰胺或特殊应用铝的使用。

Objective:To search the best method for how to use the Polyamide hydro gel in face-plasty.

目的：探讨应用医用聚丙烯酰胺水凝胶进行面部整形的最佳方法。

With the development of technology and natural resources decreasing, more and more general plastics, such as polyethylene and polypropylene has been used.

随着科技的发展和自然资源的减少，通用塑料聚乙烯和聚丙烯被越来越多地应用于生产和生活当中。

Polyethylene and polypropylene film adhesive has been used extensively in this area.

聚乙烯和聚丙烯薄膜不干胶在此领域被广泛使用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
