楼上的大虾们实在是强啊!小女子在此作揖,多谢了,最后一句还请大家伙帮忙啊!

The improved method is time-saving, easier in operation, more scientificaly supported and is suitable for batch analysis (Test).
这里的科学规范，不好翻译，中国话，太笼统，什么是科学，什么是规范？？？

科学规范 code or norms of science：
科学 science 科学的scientific
规范：code or norms 规范的 normative

创建科学规范的系级教学管理体系To establish a scientific and normative system of teaching administer of departement

太感谢了!受益非浅!

The improved method is time-saving, easy to operate, and more normative, thus suitable for batch sample test.
批量样品用batch sample就可以了。
“科学规范”按我的理解就是“标准化”，所以翻译成normative。

也多谢17楼楼主指点哦!

Suggested translation:

This improved method is (A) and (B). It is *** and (C) for batch examination.

(A) timesaving, economical with time...
(B) user-friendly, easy to operate...
(C) suitable, highly recommended...

*** I have no idea what is 科学规范

=================================================

I drafted the above before reading the translations at 13 to 17/F. After reconsideration, the translations at 13 to 17/F are better in wording and sentence structure.
