In those well-formed geometric structures, not only does the scripture express its mystery and the beauty of cutting, but it stands for the symbol of Buddhism. There are numerous works demonstrate this statement, such as "Ark of Dream,""Scriptures,""Pilgrimage of Buddhist Scriptures,""Spiral Scriptures,""Floating,""Pipal,""Big Spiral Scriptures,""Golden Mandala." Besides from placing scripture and leather into fine spatial arrangement, Huang Gang fills the golden background with dark brown dripping technique or paints a large red star. The red star series, which is combined and abstracted from China's interpretation for red, has a particular meaning.

在有规律的几何形式构成画面之中,除了倾心展现经版的刀笔之美、经文的神秘意味,经版始终是菩提灵性的表征符号,而不仅仅是一种简洁的对象,例如《梦之舟》、《佛经》、《朝经之路》、《转经》、《行云流水》、《菩提树》、《大转经》、《金色的曼陀罗》等,进一步地,在空间表现上,在经版或皮革构成的实体空间之外,其非实体空间恰当地运用了书写性和涂绘性的表现主义语言风格,在经版的金黄色域背景上涂绘、滴沥黑褐色,有的则间以大漆涂刷那些红星。

The induction motor stator-flux-oriented vector control scheme not only reduces the big dependence of its performances on the rotor parameters, such as in the rotor-flux-oriented vector control, but also eliminates the torque ripple produced by Bang-Bang control in Direct Torque Control. So the SFO vector control is a high-performance and robust induction motor control scheme.
