杜仲胶

It is pointed out that the birth of the high elastic Eu gum, the discovery of the three stages of vulcanizing process and the three kinds of different materials, which correspond to the three stages, the building of the systematic material engineering and the development of the concept on "Unitary Material-Spectrum composed of rubbers and plastics"have brought the study on EU gum into a new stage,and moreover,promoted the development of a series of new functional materials.

指出：高弹性杜仲胶的诞生，杜仲胶硫化过程三阶段及与之对应的三类不同材料的发现，杜仲胶材料工程学的形成及"橡一塑统一材料谱"概念的提出，把杜仲胶的研究及开发带到了一个新阶段，进而推动了系列功能材料的开发。

There is no thorough report so far on gutta-percha in samara, bark and leaf.

杜仲的果皮、树皮、叶片内都含有杜仲胶。

These balls were actually made of the gutta-percha resembling a rubber.

到了十九世纪五十年代末，经过研究和改良，发明了橡胶球，这种球实际是用杜仲胶制作而成的，杜仲胶类似于橡胶。

The performance indexes of gutta-percha sulfide modified asphalt samples with different proportion were detected,the optimum proportion and modified effect were discussed.
