Second class "Activity 0 courses generally use non-directive Teaching mode, the teacher's task is not to teach students knowledge, nor is teaching students how to learn, but to provide students with a means of learning by the students themselves to decide how to learn, which makes teachers in the teaching practice and the development of teaching materials there is considerable difficulty, non-directive Teaching mode is designed to guide students to master learning orientation and learning methods, but because teaching in the various uncertainties, it will backfire the second class of the "class" courses commonly used mode of delivery, strong teacher-led, less interaction with students in training and development of students' personality deficiencies are obvious.

The design and construction of Zhang River in Dangyangsection riverbank protection is proposed follow the following principles: to meet embankment stability requirements, and reduce the project cost; minimize the rigid structure, enhance the the revetment visual “soft effect”;select plants and the range of their cultivationaccording to tax range; porous structure should be set for the biological habitat; maximize the use of natural materials to avoid secondary environmental pollution.

It enables to identify the influence of a fixture’s geometrical characteristic, material, colour, transparency and roughness, as well as of the alignment of the part coordinate system (PCS) mathematically relating to the machine coordinate system (MCS).
Material and Methods The Coord3-MC16 CMM used during the entire experiment provides a performance specification of 5+5.L/1000 µm (with L in mm), according to ISO 10360-2 [8].

Thirdly, the researches taken by science organizations on the supervision are not deep enough.
Base on the data from The Net of Chinese Journal, only 109 articles mark “Waste Oil” as key words.
The cost on raw material transportation would sharply decrease with steady supplement of the raw materials when local government shoulders the responsibility to collect the oil.
The main sale channels of biodiesel summed up from telephone interviews with some biodiesel producers are as follows: 43% of the biodiesel are sold to countryside, 29% as boiler fuel of factories, 14% as raw materials for chemical industry, and 14% to foreign countries.
Used as raw materials of biodiesel by the producers in China, the waste oil would no longer challenge the food security, and to a certain extent support the energy security at the same time.
