Because the content of amylose is the most important index among these factors and anti-Waxy gene is the primariest gene controlling the content of amylose, we systemically expatiated the Wx location and its equipotent genes.

在影响稻米食味品质的诸多因素中，稻米直链淀粉含量是一项最重要的指标。

Ethanolamine derivatives were aliphatic compounds, so the yields of cantharidinimide derivatives were only influenced by steric hindrance effect.

在与ethanolamine的衍生物反应时，因为ethanolamine是一个直链的化合物，所以产率只受到立体障碍的影响，当立体障碍越大时，产率也就越低。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

Due to its linear chain structure, polyacrylamide, combined with DDA, tends to form the high molecular collector with more surface activities. In addition, with the high molecular weight, polyacrylamides (with the exception of hydroxamic acid polyacrylamide) can strongly flocculate kaolinite, which can increase the adsorptive density of collector and activate the kaolinite flotation.

由于分子的直链结构，聚丙烯酰胺药剂易与捕收剂十二胺形成表面活性更高的高分子捕收剂，同时由于聚丙烯酰胺具有较高的分子量，对高岭石显示很好的絮凝作用，增加了捕收剂的吸附密度，活化了高岭石的浮选。

The quantitative relation model was established between the fundamental or sum frequency and properties of straight-chain alkanes.

在此基础上建立了直链烷烃的物化性能与基频和总频之间的定量相关模型。

The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P（210cm）is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.

研究表明：（1）随深度的增高及植物残体中木本残体的增多，总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高，而易水解物含量减少；（2）GC- MS分析显示，正构烷烃，直链烷基2-酮和正烷醇均以长链组分为主，揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主；甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据；（3）通过有机分子标志物与孢粉、植物残体等指标的对比研究表明：脂类化合物对气候变化的反映要比植物种灵敏得多，不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一；（4）泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响，短时间尺度，泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响；长时间尺度，泥炭地有机碳的转化，受气候条件控制；（5）总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律，分析结果显示该泥炭地层形成过程中，1500a B.P（210cm）可作为划分前后晚全新世的界线，前期的基调是气候偏暖，但又有几次偏干冷气候的反复，后期气候以干冷为主，其间虽有几次上升波动，但整体趋势不变。

本文报道了对云南省100个水稻样品，其中包括81个地方种、10个改良种和9个低直链淀粉含量突变体进行十二烷硫酸钠聚丙烯酰胺凝胶电泳分析的结果。

Results showed that the hardness,adhesiveness and gumminess measured with texture analysis instrument by TPA method are significantly correlated to those of sensory evaluation,so the texture analysis can be adopted to evaluate the sensory quality.

结果表明，采用TPA模式通过质构分析仪测定的硬度、黏着性和胶粘性与感官指标有显著相关性，可以用质构仪测定的质构指标来表示感官评分相关指标；理化特性中直链淀粉含量和胶稠度与感官评分呈极显著负相关，碱消度与感官评分呈极显著正相关。

In the research,four indexes are developed to describepost-dryingpaddy quality.1Outer appearance index:stress crack percentage.2Physical-chemical index:protein,amylose,fat content.3Husk rice index:head rice yield.4taste index:cook character,taste score.

本文提出了确定水稻干燥后品质的四类指标：1外观品质：爆腰率；2理化指标：蛋白质、直链淀粉和脂肪的含量；3碾米品质：整米率；4食味指标：稻米的炊饭特性、糊化特性及食味值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
