Miles,
   Thank for you advice, as your advice, I have been installed the
debug tools, try to find out which process cause the generate time is
so slow,
but I just cannot identify which module cause this problem ,   since
from the timer session time used in render the element is so little,
can you give me an suggestion which part of the report I need to focus
on ?
   really thanks for your advice.

                              化學是一門研究物質的性質、組成、結構、變化,以及物質間相互作用關係的科學。「化學」
一詞,若單從字面解釋就是「變化的科學」之意。化學如同物理皆為自然科學之基礎科學。很多人稱化學為「中心科學」(Central science),
因為化學為部分科學學門的核心,例如材料科學、奈米科技、生物化學。

                              化學研究的對象涉及物質之間的相互關係,或物質和能量之間的關聯。傳統的化學常常都是關
於兩種物質接觸、變化,即「化學反應」,又或者是一種物質變成另一種物質的過程。這些變化有時會需要使用電磁波,當中電磁波負責激發化學作用。不過有時
化學都不一定要關於物質之間的反應。光譜學研究物質與光之間的關係,而這些關係並不涉及化學反應。
