PE-RT is referred to as the Polyethylene Raised Temperature, it is by the ethylene monomer and 1 - octene copolymer from monomers is specifically designed for the heating system of medium-density ethylene - octene copolymer, which has a narrow molecular weight distribution , octene uniformly distributed in the polymer main chain on the special molecular structure, it retained the original PE performance and processing properties of the health advantages, but also strengthen the durability of a new type of high-temperature resin pipe.

PE-RT是Polyethylene Raised Temperature的简称，它是由乙烯单体和1-辛烯单体共聚而成的，是专门为采暖系统而设计的中密度乙烯－辛烯共聚物，其具有分子量分布狭窄，辛烯均匀分布在聚合物主链上的特殊分子结构，它既保留PE原有的卫生性能及加工性能等优点，又强化了高温耐久性的一种新型管材专用料。

After comparing the examination result with the common biological indicators, we notice that the organic substances in the samples collected from the mud volcanoes mainly come from land higher plants and the result of the redeposit after washing out the upstream's deposit, this conforms the geographic location in the mountains and the luxuriant plants in the region, hoping this research result can provide reference values for the future land developers, in order to take advantage of the land as much as possible, aw well as a perfect planning and conservation of the mud volcano.

将检测结果与常见的生物指标比对后，发现所取泥火山样品中所含的有机物质主要来自於陆生高等植物及上游沉积物经冲刷后再沉积的结果，这和泥火山的地理位置位於山区且附近植被茂盛是相符合，希望这样的研究结果可提供将来土地开发者参考，对这块土地做最好的利用，并对泥火山做完善的规划与保留。

The rich active ingredients retained work to regulate skin's functions, replenish with required trace elements and nutrients, and improves metabolism and nutrient replaceability.
