Because of the flexibility of enveloping method than dentiform normal method, three new screws are designed by enveloping method with flow field analysis .

由于包络法比齿型法线法应用简便，因此我们采用包络法设计了三种新型螺杆元件，并对其分别进行了流场分析。

The traditional way to manufacture the gashes of gear hob cutter is to mill it one by one, but the efficiency is quite low. With the proposed manufacturing process, the gashes could be generated by another specially designed hob cutter so that the manufacturing efficiency could be improved 2~3 times.

滚齿刀容屑槽之传统加工方式，系利用成型铣刀逐槽加工而成，除加工时程冗长外，铣制ZK 型蜗杆之缺点亦无法避免，本文再次利用滚制方式形成容屑槽，并解决传统制程上述之缺失。

With the increasing of water lever, Myriophyllum spicatum increased the plant height, allocated more biomass to their leaves and decreased the allocation to roots and stems. However, Potamogeton maackianus allocated most biomass to their stems and decreased the allocation to leaves and roots.

实验发现：随着水位上升，狐尾藻株高也增加，并且将更多的生物量分配到叶片部分，减少对根和茎的资源投入；而微齿眼子菜则将生物量大部分投入到茎杆，减少对叶片和根的资源分配。

While the species percent of Cyanobacteria and Chlorophyta decreased to 61.5%, as compared with 76.8% in control. Several diatom species, such as Synedra ulna, Nitzschia denticula, Nitzschia acicularis, Gomphonema constrictum var.
