It was shown that the absorbing rate of hybrid rice and it restorer for store material and for photo - material was 50 % and 80 % respectively , and the absorbing rate of hybrid rice was a litter higher than that of its restorer 结果表明，杂交组合及其相应恢复系的籽粒对标记储藏物质及标记光合物质的吸收分别达到50 %和80 % ，杂交组合籽粒的吸收量高于相应的恢复系，但差异不大，说明在储藏物质与光合产物的运输方面，杂交组合比相应的恢复系之间无明显差别。
While the fruits ripening process was delayed in leetrl antisense fruits . epinastic of leaves in leetrl antisense plants was only occasionally observed , which was not observed in leetr2 antisense plants ; ( 5 ) when treated by exogenous ethylene ( 25ul / l ) , the abscission of antisense leetr2 petiole explants was delayed . moreover , leaf epinasty failed to be induced by ethylene treatment c , which suggested that these tissues were insensitive to ethylene ( 5 )植株衰老和叶片脱落延迟，花瓣脱落也明显的延迟，在转反义leetr1基因番茄的果实成熟特性被明显改变，表现在乙烯释放高峰延迟，果实颜色出现变异，以及和成熟相关的酶活性的改变，然而，转反义leetr2基因的果实的成熟特性与对照相比无明显差别。
Abstract : methanesulfonic acid method was used to prepare five acylated chitins . except heptanoyl chitin , four of them , i . e . acetyl chitin , propionyl chitin , butyryl chitin and hexanoyl chitin , had high degree of substitution ( from 1 . 5 to 2 . 0 ) and exhibited lyotropic liquid crystalline behavior and cholesteric phase . as the length of the side chain increased the critical concentration ( w / w ) somewhat increased from 0 . 21 to 0 . 26 because the chain rigidity dropped . the critical concentration values of all the four derivatives were much higher than that of chitin ( 0 . 12 ) due to the decrease of intramolecular hydrogen bonds . the four acylated chitin can form typical banded texture after being sheared . there minimum concentrations to form banded texture of them were evidently different , varied from 0 . 25 ( for acetyl chitin ) to 0 . 37 ( for hexanoyl chitin ) . these results further indicated that liquid crystallinity decreased while the length of flexible side substituents increased 文摘:四种羧酰化甲壳素即乙酰化、丙酰化、丁酰化和己酰化甲壳素在二氯乙酸溶液中均呈现胆甾型溶致液晶相.临界浓度随侧基长度增加而略有增加，衍生物的临界浓度明显都比原甲壳素高许多，这些规律都可以用链刚性的变化来解释.四种羧酰化甲壳素在剪切时均能形成条带织构，而且能形成条带织构的最低浓度有明显差别，随侧基长度增加而提高，进一步表明侧基较长，液晶性减少
The results show that uf is efficient for the removal of bacteria and turbidity with the 99 % removal of bacteria achieved and residual turbidity within 0 . 02 ntu in the treated water ; the uf resulting toc and uv _ ( 254 ) removals of ha are 30 % and 40 % ; there is no obvious difference of ha removals between the uf membrane with a mwco of 10 kdaltons and the other one with a mwco of 1 kdaltons 实验结果表明，超滤具有良好的灭菌和除浊功能，细菌去除率达99以上，过滤出水的浊度能控制在0 . 02ntu以内，直接超滤对腐植酸toc去除率为30左右， uv254的去除率达40 ，截留分子量为10万道尔顿和1万道尔顿的两种超滤膜对腐植酸的去除效果无明显差别。
At first , construct ten sets of surrogate data for each emg data , then calculate the correlation dimension ( dcorr ) , correlation time , maximum lyapunov exponent ( a , ) , l - z complexity and approximate entropy ( apen ) of both the original emg data and surrogate data , and then compare them 构造这四例肌电信号的代替数据(各十组) ，分别计算原数据及其代替数据的关联维、关联时间、最大李雅普诺夫指数、 l - z复杂度和近似熵，我们发现，四例原数据的以上所有特征量都与各自所对应的十组代替数据存在明显差别。
A kind of special encasing material is developed and used to reinforce the part in the project , which can compound different color according to different requirement . it provides obvious gray scale contrast between the image of part and encasing material and it can obtain the accurate contour of a part ' s cross section . this kind of material has good machinability , additives and proper toughness . the whole encasing process is simple and rapid 本项目开发研制了一种专用封装材料来封装被测零件，封装材料根据不同的需要，可以配置出不同的颜色，使得与被测零件的图象颜色具有较明显差别，能够提取出精确的零件截面的边界轮廓，并且具有良好的粘合性能、机械性能和适当的韧性，操作也比较简单。
Analysis for the product hydration process of natural maintenance show tailings and quartz sand surface is advantage for the major influence of hydration outcome in jing pei generate " base role " , do not participate in chemical reaction basically , while steam temperature and pressure for hydration structure and form of low silicon - tailings aerocrete have obvious influence , it is why the compressive strength of two products have obvious difference 对自然养护的制品水化过程分析的研究表明，尾矿和石英砂表面对于水化产物的主要影响是利于晶胚生成的“基底作用” ，基本不参与化学反应，而蒸压温度和压力对低硅尾矿加气混凝土水化产物的结构、形态有着明显的影响，导致两种制品的抗压强度有明显差别。
Sds - page results showed that there was a clear target protein band in mut + recombinant supernatant after 48 hours of culturing , while a faint band only in muts recombinant after 72 hours . western - blotting result showed that there was no remarkable difference of yield between mut + and muts recombinants after 6 days induced . anti - virus activity tests revealed that culture supernatants of mut + and muts recombinants could inhibit tmv infection with high efficiency in the same concentration and there was no significant difference between them 结果表明，诱导培养48小时后， mut ~ +重组菌株表达产物在sds - page胶上显现出清晰的目的蛋白带，而mut ~ s重组菌株培养72小时才能显示微弱的目的带； western - blotting杂交信号强度表明，同样培养6天的mut ~ +和mut ~ s重组菌株表达产物在表达量上没有明显差别。
The research on the condition of kid ' s suckling indicates that the highest milk - dotting activity ( 26108su / g ) was obtained for the whole suckling section , whereas proteolytic activity were no significant different between the whole suckling and random section ( p > 0 . 05 ) , but proteolytic activity ( 1925u / g ) was highest for the complete grass - feeding , which demonstrated suckling could stimulate the continuous secretion of chymosin in the abomasum 羔羊哺乳状况研究表明，全哺乳组凝乳活性最高( 26108su g ) ，蛋白水解活性与随机哺乳组无明显差别( p 0 . 05 ) ，而全喂草料组蛋白水解活性最高( 1925u g ) ，这表明哺乳能够刺激皱胃中凝乳酶的持续分泌。
