“Zaofeng” (the clone of sport deviation of Huaji)“Huafeng” and“Qianfeng” (the new lines of nucellar embryo Navel Oranges) and“Zaosha pomel”(the excellent line selected from seedlings of secondary generation of shatianyou) are described in this paper.

The leather treated with RF-1 has excellent properties such as better fullness,elasticity,softness and waterproof.

The rela tionship between compression coefficient(Kc) and fullness of leather, which was evaluated by hand, has been discussed The results have indicated that: (1 )Kc related to fUllness of leather.

Middle-shear and high - shear viscosity, rheological property, storage stability, fullness of film and scrubbing resistance of emulsion paint are improved effectively by use of Clariant T-180 powder modifier with the specific anchor group, hydrophilic and hydrophobic features.

The weight, as well as the fullness(K) for males are less than that for females of corresponding length.

With the hydroxyl acrylic resin for car topcoat as example, this paper discusses the difference of domestic car topcoat resin with overseas products of the same type in the aspects of gloss, fullness, PGD and anticorrosion performances; and puts forward the measures for improvement.

After applying this profile in design of valve-train cam of motorcycle engine,it is proved that this cam profile have same and better characteristics than cam profile of Honda motorcycle CG engine,which can not only maintain a high ample factor and increase output power,but also reduce impact,vibration and noise of engine which is working.

According to the calculated results, with higher ample factor, FB-Ⅱ cam is an ideal selection for engine with a s.
