The results show that the method of drying at initial temperature of 35℃, and increasing temperature at a rate of 5℃/h to 60℃, keeping the temperature at 60℃ for one hour, then decreasing the temperature to 50℃, is favorable for the dehydration and color protection of Pleurotus eryngiu.

研究结果显示，采用始温35℃，以5℃/h的速度升温，至60℃条件下保持1 h，再逐渐降温至50℃的干制方法有利于杏鲍菇的脱水以及色泽的保持。

Polymorpha cells in low level and produced a 1. 5kb transcript. Transcription of the gene was slightly repressed by exogenous △9 UFA. The FAR element in S. cerevisiae OLE1 promoter described by Choi et al. might not be crucial for positive transcriptional regulation of H-OLE1 gene.

Northern杂交发现，H-OLE1基因在细胞中以较低水平表达，产生1.5kb的转录子；基因表达略受不饱和脂肪酸的抑制；在多形汉逊氏酵母H-OLE1基因的转录调节中，Choi等在酿酒酵母OLE1基因中发现的脂肪酸调节元件FAR可能不是关键的。

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。

RESULTS: After 24 hours of preinduction, cells changed from spindle to polygonal or irregular, with many short rod-shape processes and 2-3 nucleoli. Whirlpool shape growth disappeared, and was disordered. After 1-3 hours of induction, cells gradually became round, with significant cell contraction, strong refraction, bipolar or pluripolar processes connected each other into a net. After 5 hours of induction, grades one and two branches were detected.

结果：预诱导24 h，胞体由原来的长梭形变成多角形或不规则形，伸出多个短棒状突起，可见2~3个核仁，细胞间漩涡状生长趋势消失，排列无规律；诱导1~3 h，细胞逐渐变圆，胞质收缩明显，折光性增强，双级或多极的突起互相连接呈网状；诱导5 h，突起出现一、二级分支。

A design method is derived for decentralized observer-based controller, which makes the closed-loop system quadratically stable with an H〓-norm bound for any admissible uncertainties.

在此基础上，研究并提出了当控制器在规定范围内的一部分失效时的分散H〓可靠控制问题，提出了能保证闭环系统可靠稳定和具有一定H〓性能的分散可靠控制器的设计方法。

The Rhodococcus sp.H-412 screened by ourselves in the lab, which possessed the 4S desulfurization metabolic route, was chosen as the target. Conditions of its immobilization and application were main analyzed by using DBT as a model compound.

本文以实验室筛选的、符合4S脱硫代谢途径的Rhodococcus sp.H-412为研究对象，二苯并噻吩为生物催化脱硫模拟化合物，考察了脱硫菌Rhodococcus sp.H-412的固定化操作条件和使用条件。

We concluded that DGR was probably an independent etiological factor and might play a synergistical role in the pathogenesis of gastric mucosal lesions along with gastric acid and H.

DGR与H。 pylori感染和胃内酸度均无关，DGR可能是一个独立的致病因素，与H。

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。
