查询词典 dissipative measurable transformation

The catalytic transformation pathway can change to decrease the yield of hydrogen and yield methyl-contained sulfides such as methyl mercaptan, dimethyl sulfide and dimethyl disulfide, but overlarge concentration of methanol would holdback the transformation of isobutyl mercaptan. The transformation of isobutyl mercaptan was favorable if the volume ratio of methanol and benzene was 0.2.The addition of methanol assume certain effect on the catalytic cracking of di-n-butyl sulfide in solvent benzene but without changing the cracking reaction mechanism of di-n-butyl sulfide.

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。

The protein had the same antigenicity as IgG, and the change of the protein had the same tendency as SHP-2, which was higher in canceration groups than in uncanceration groups and control groups in thymus cells, but there weren't significant change in bone marrow cells;⑧ The change law of the expression of SHP-1 and SHP-2 during γ-ray induced malignant transformation in BEAS-2B cell is that the expression of SHP-1 was increased synchronistically with malignant transformation of cell, and the expression of SHP-2 didn't have significant correlation with malignant transformation of cell.

癌变组胸腺细胞中SHP-2 mRNA编码PTPase催化区的700～1096bp间可能出现甲基化；⑦癌变组的胸腺细胞中存在一相对分子质量约为55×10〓的蛋白质，它与IgG具有相同的抗原性，其表达量的变化趋势与SHP-2的蛋白表达变化趋势基本一致，即在胸腺细胞中明显高于对照组及未癌变组，但在骨髓细胞中对照组高于癌变组；⑧SHP-1、SHP-2在γ射线诱发的BEAS-2B细胞恶性转化过程的变化规律：SHP-1蛋白表达量的升高与细胞的恶性转化在时间上基本一致，而SHP-2蛋白表达量与恶性转化无明显关系。

Firstly, affine covariant neighborhoods of visual words are used to verify the spatial consistency. Secondly, a set of affine transformation matrices between the corresponding covariant regions is calculated, and the matrix with the most inliers is chosen as the best matching affine transformation matrix. In this step, only a single pair of corresponding affine covariant regions is used to calculate the 6 degree of freedom affine transformation for acceleration. In the last step, the spatial consistency is verified by the BMATM.
