Agricultural Sciences in China 2005年第5期4卷 348-354页

Two wheat cultivars, GC8901 (hard winter wheat) and SN1391 (soft winter wheat), were used for investigating the changes of enzyme activities for sucrose metabolism and starch biosynthesis and the accumulation character of starch composition. The result showed that activities of sucrose (SS), sucrose-phosphate synthase (SPS), adenosine diphosphorate glucose pyrophrylase (AGPase) and soluble starch syntheses (SSS) of 1391, which have more starch, were significant higher than those of 8901, that with low starch content. But the changing of granule-bound starch synthase (GBSS) activity was consistent with the amylose content, which indicated that amylose contents in grain were determined by GBSS activity, especially the activity at later grain filling stages. Simulating with Richards equation showed that it was initiating time and accumulation rate, but not accumulation duration that determined the content of starch composition. Furthermore, changing of sucrose transport capacity was consistent with SSS and GBSS activities, starch accumulation rate was accordant to AGPase and SS/SPS ration, not SS, SPS, SSS or GBSS activities. The results suggested that there was no inevitable relation of starch accumulating rate and starch composition contents with the activity of single enzyme such as SS, SPS, SSS or GBSS, but closely related to AGPase activity and SS/SPS ratio, and it was SPS and AGPase that play a vital role in the biosynthetic pathway. Later polymerization reactions catalyzed by SSS and GBSS don’t seem to control the rate of starch accumulation, but do affect starch structure.

一般认为声音与意义之间的关系是任意的,是一种约定俗成的关系。在对民国时期新生单音节词的字素义的分析中,发现字素义与词义之间有着密切的关系。运用字素分析法,对单音节词构成部件的意义进行分解,可以挖掘新造字、新生词意义的产生机制和规律;由此现象入手,进而扩展到形声兼会意字中音义关系的系统性和能产性,从而提出音义关系的系统性,不仅是词汇系统性的表现,也是生成新词的基本依据。根据音义关系的系统性原则,可以对当代汉语中新生词的字形和意义进行规范化整理;也有利于生成新的规范汉字、新的规范词。此外,字素分析法的运用也为分析单音节词的内部结构、发现词义生成的规律拓展了思路。

研究合成单宁在锦纶和蚕丝织物上的吸附性能及其差别。结果表明:合成单宁按Langmuir-Nernst二元吸附机制在锦纶和蚕丝织物上发生吸附,且表现出吸热效应;由于蚕丝氨基含量高,锦纶中存在大量的亚甲基,Langmuir吸附在蚕丝总吸附中的贡献大于在锦纶总吸附中的贡献,在蚕丝织物上的吸附对pH值更为敏感;锦纶膨润性较蚕丝差,空隙尺寸较蚕丝小,使得合成单宁在锦纶织物上的吸附对温度更为敏感。

少井区烃源岩难以通过井震标定提取准确子波、构建精细低频模型。为此,提出根据盲信号理论的少井区烃源岩叠前地震反演预测方法。首先,根据盲信号理论,利用地震数据高阶统计量提取地震盲子波,再根据贝叶斯理论在复频域内估计模型参数的低频分量;然后,利用得到的地震盲子波及复频域低频模型在复频域内进行弹性阻抗反演;最后,利用烃源岩地震岩石物理模型构建弹性阻抗与烃源岩物性参数之间的关系,并通过弹性阻抗反演得到烃源岩的泥质含量、烃源岩指示因子等物性参数,从而预测少井区烃源岩的空间分布特征,定量评价烃源岩。该方法中,地震子波盲提取是一种统计性子波提取方法,不需要井数据参与,可为少井区烃源岩的叠前地震反演提供先验约束,解决了无井或少井区无法进行确定性子波提取的问题。模型试算和实际资料应用结果均表明该方法可靠、准确。

为研究并有效控制活性染料在冷轧堆染色中的水解,应用高效液相色谱（HPLC）对双乙烯砜型活性染料C.I.活性黑5在低温下的水解性能进行定性及定量分析。结果表明：在碱性缓冲液中,C.I.活性黑5的消除反应及水解反应为假一级反应,其消除反应速率及水解反应速率均随着缓冲液pH值的增加而显著提高;在30℃、pH值为9时,C.I.活性黑5的水解反应速率常数为3.5×10^-5min^-1;相同温度下,在pH值为10、11、12时该染料的水解反应速率常数分别是pH值为9时的3、27、233倍,因此,C.I.活性黑5在冷轧堆染色时,在pH值为9－10的缓冲液中水解稳定性较好。
