遗传影响

In this paper, the effects of filter paper on the shoot induction and genetic transformation of Artemisia annua were studied.

本文首先研究了滤纸对青蒿丛生芽诱导的影响和在遗传转化中的应用，进而研究了反义鲨烯合酶基因表达对青蒿素生物合成的影响。

This study was aimed to find single nucleotide polymorphism in the promotor region of asparagine synthetase gene and to determine if these SNPs have influence on the transcriptional activity of AS promotor.

本研究旨在通过筛查发现AS启动子区的单核苷酸多态性位点，研究它们对AS基因表达量的影响及寻找对Lasp治疗反应具有影响的个体遗传因素。

The factors affecting postfrac productivity are discussed in the paper. The grey associability ordering indicated that the postfrac productivity was lowly correlated with the permeability interpreted by the original log data and mainly influenced by porosity, then effective thickness, and then shale content and formation pressure. In light of the genetic neural network method, the productivity of gas well was predicted by use of the log data through programing and model training. The error detecting result proved that the model was reliable and a good application effectiveness was obtained.

文章对压后影响产能的因素进行了讨论，灰关联度排序表明，压后产能与原始测井解释的渗透率关联性小，而主要影响因素依次是孔隙度、有效厚度、泥质含量和地层压力；引用遗传神经网络法，编制预测程序，利用测井资料通过模型训练，对气井的产能进行预测，误差检验验证了模型的可靠性，取得了良好的应用效果。

To RPC, the fluidity was usually a key index, because it directly reflected the work-ability. The effect factors were complex, however, the quantity relation between the RPC fluidity and its effect factors could not be expressed with a uniform numeric formula. There was no effective method for this problem at present. In accordance, a numeric method which used for controlling the RPC fluidity was advanced. The neural network model based on genetic algorithm was introduced for a aptitude method consequently.

流动度是RPC配制的一个关键指标，它直接反映了其工作性的优劣，但其影响因素复杂，难以用统一的数值关系直接描述RPC流动度与其影响因素的量化关系，目前还没有合适的计算方法，为此，提出控制RPC流动度的数值方法，即引入遗传神经网络对RPC的流动度进行预测控制。

This amount of genetic manipulation has a profound effect on the biology of xenotransplantation, but a negligible effect on the pig.

遗传改变的量对异种器官移植的生物学有著深刻的影响，但是对猪的影响却可忽略不计。

Human behavior has been seen as the results of interactions between heredity and the environment factors.

人类行为既受到遗传因素的影响，同时也受到环境因素的影响。

Certainly some important traits are partly inherited, such as physical size and particular measures of intelligence, but those influence what a person doesn't do more than what he does; a five-footer will never be an NFL lineman, and a seven-footer will never be an Olympic gymnast.

当然，一些重要的特征还是部分来自于遗传的，例如身体形态和一些特异的能力，但是这些影响没有比他们自己对自己的影响大；一个五英尺高的人绝对不会成为国家足球队的前锋的，一个七英尺高的人绝对不会成为奥运体操冠军的。

There are many factors that will affect genetic diversity of pines,in which mating system and environment are two main factors.

影响遗传多样性的因素很多，其中自身的交配系统和外部的生长环境是影响它的两个主要因素。

Analyzing the relations among betulin content and growth status, geographical location and climatic factors, it was found that the effect of growth status on betulin content was not significant, and betulin content was not only affected by self-provenance and heredity background but also by geographical location and climatic factor.

进一步分析可得，同龄树种的生长状况对白桦酯醇的含量影响不显著；而白桦酯醇的含量不仅受自身种源及遗传背景的影响，同时也受到其所处地理位置和气候因素的影响，即属于基因与环境互作的表现性状。

The effects of age on any individual are determined by a number of factors including environmental impacts, diet, activity levels, weight control and especially genetic predispositions.

的影响，年龄对任何个人是取决于多项因素影响，包括对环境的影响，饮食，活动水平，控制体重，特别是遗传倾向。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
