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。

Thirdly, the precipitation phenomena and pH-curves of the compressed COi-ethanol-water system with BSA or lysozyme were studied, and it was found that: BSA would precipitate when pH of solution decreased close to isoelectric point, and the precipitate would redissolve when pH decreased further.

蛋白质分子结构数据表明，乙醇还在一定程度上改变了蛋白质分子的表面结构，这影响到了蛋白质的缓冲能力等特性，从而乙醇对加压CO_2-乙醇-水-蛋白质多元体系的pH变化有降低的作用，这使体系可处理的蛋白质浓度较加压CO_2-水-蛋白质体系大幅度提高。

Compared to the sample without ultrasonic treatment, it was found that, for AZ31 magnesium melt alloy treated by ultrasonic, the refined grain size and the inproved distribution of grain with its shape of oval-shaped or spherical can be obtained, and the precipitation inside Al matrix was inhibited The Mg17 Al12 precipitates distributed mainly along the grain boundary and hardness was improved remarkedly.

通过对铁合金AZ31进行熔体超声处理发现，处理后试样的晶粒较未进行超声处理的试样有明显细化，分布均匀程度提高，形状呈椭圆状或球状，合金元素Al在晶粒内的析出被抑制，Mg17Al12第二相的析出主要集中于晶界，硬度有明显提高，并且通过试验确定出了最佳处理功率和时间，为超声波在铸造生产中的应用提供了依据。
