The results showed that 7-day-precultured embryogenic calli had the best responses for bombardment among 2-7 day' preculture duration. Enhanced transformation efficiency was found in the explants treated with high osmotic medium 4h prior to till 24 h after bombardment. Particles of gold and tungsten were both found suitable for rice transformation and there was no adverse effect when tungsten particles were reduced to 1/3 standard amount for DNA precipitation on transient GUS gene expression. However, it was found that gold particle had higher GUS expression at 120 h post-bombardment. A preliminary microprojectile transformation system with an average of 15-20 blue spots/explant GUS expression was routinely obtained for 'Tainung 67' by using the particle gun with 1,100 psi rupture disk, 6 or 9 cm microcarrier flight distance and 4 mm of macrocarrier flight distance setting.

初步结果显示，以预培养2~7日之胚性癒合组织逐日测试转殖率，以预培养7日之培植体表现最佳；培植体於转殖前4小时至转殖后24小时以高渗透压培养基处理，有助於转殖效率之提高；比较金、钨粒子对转殖率在转殖后48h並无不同，但转殖后120 h取样，则金粒子组有较高之蓝点数；钨粒子用量可减少至1/3標准用量对转殖率並无影响；利用基因鎗在使用1， 100 psi裂碟片、大载片至挡片之距离为4 mm、微载髁至射击目標之飞行距离6或9 cm之设定，GUS基因表现之平均蓝点数均可达15~20个／培植体。

Due to Jin's use of negative shots, this series of photographs does not correspond to the realist reflectionist theory right from the very beginning. It does not reflect or present any social phenomenon. Instead, it transforms the phenomenon into a problem situation that offers and invites review. In contemporary art, to intervene society by way of negation is strategic, as can be seen in Jin's Great Economic Retreat: the images featuring empty factory buildings reveal more than that. When the enlarged photos are exhibited in a museum gallery, Jin's real question surfaces: is what post-colonial economy brought China a blessing or a curse?

金江波的这组《经济大撤退》图片由于用了否定性的镜头而使得它一开始拍摄的时候就不是现实反映论的，它不是去反映和呈现了社会的什么现象，而是将这种社会现象转换为一种问题情境，提供给人们反思，而在当代艺术中，否定性地介入社会是它的核心，就像金江波的《经济大撤退》，图片虽然呈现了空厂房，但不只是呈现了空厂房，当这些图片通过放大展示在美术馆中，那些后殖民经济对中国来说到底是喜还是忧才是金江波想要问的？
