The author first reported the social phenomenon and synchronizing development incryptosporidia,the dynamic process of the sporozoites or merozoites aparted from theirparent substances and developed into trophozoites,the culture of C.baileyi in chickenembryo,and the excysting process without both the trypsin and the sodium taurocholatein 37℃ water.The high levels of excystation(60%)oceured at 37℃ water showedthat temprature was very important in cryptosporidia excysting process.

在国内首次观察和描述了薄壁型隐孢子虫卵囊；首次报道隐孢子虫具有群体寄生现象和同步发育特征；首次描述了隐孢子虫的裂殖子或子孢子离开母体和发育为滋养体的动态变化过程；首次应用粪便中纯化的C.baileyi卵囊感染鸡胚成功，并用37℃水脱囊，其脱囊率高达60％，表明温度对隐孢子虫的脱囊具有重要作用，无需胰酶和牛胆酸钠的参与。

Then, the experiment that edelfosine inhibited the phosphatization of Spm1 was carried out in order to elucidate whether edelfosine affect on the phosphatization of Spm1 induced via Mid2 and inhibited via Pmp1.(1)、On the inhibition experiment of parallel growth of S. pombe wild-type cells, spm1 mutants, pmp1 mutants, mid2 mutants and relevant retransform strains, the spm1 mutants grew well treated with 5.0μM and 10.0μM edelfosine for 24 h; the growth ratio of spm1 mutants had a statistic significance in between the cells previously mentioned and the S.

(1)、通过野生型粟酒裂殖酵母和胞质分裂突变体spm1Δ、pmp1Δ、mid2Δ及其再转化株对依地福新的平行生长抵抗试验，进一步确定依地福新对spm1、pmp1、mid2基因的影响；(2)、应用依地福新对Spm1磷酸化的影响试验，阐明依地福新是否通过影响Mid2蛋白和Pmp1蛋白的表达而影响Spm1蛋白的磷酸化。

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。

Saccharomycetales An order of the Ascomycota, containing the yeasts, in which the mycelium is poorly developed or absent, and the vegetative stage comprises mainly single cells that reproduce asexually by duding or fission.

酵母菌：隶属子囊菌纲，包括酵母。其特点为菌丝体发育不良或完全缺失，营养体主要是进行出芽生殖或裂殖的单细胞。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
