Firstly, this paper researched the mechanism of tubing string vibration when natural gas flows in horizontal well tubing string. Secondly, established whole tubing string undamped and damped vibration system model according as reasonable assumption data of one horizontal well. Apply finite element analysis software to calculate tubing string natural characters, simple harmonic dynamic behavior of stable gas production and nonlinear dynamic behavior. Finally, this paper carried out the safety varied frequency of gas well and the method of vibration reduction.

That every originary presentive intuition is a legitimizing source of cognition, that everything originarily (so to speak in its "personal" actuality) offered to us in "intuition" is to be accepted simply as what it is presented as being, but also only within the limits In which it is presented there.

每一种原始直觉产生于合理的认知。一切原始对象（可以说在其&个人&的现状）提供的&直觉&，我们要接受它是作为简单地存在，但也只能在在其限制范围内接受。。

With the parameters varies within the range of our study, the simulation results compared with their corresponding monochromatic output show that: the wavelength accumulation effect upon the output is small; therefore, it is reasonable and feasible to employing the monochromatic model to deal with the BGOCS systems with broad-band source; the difference between the accumulation output and the monochromatic output decreases with the increase of the current to be measured in the total wavelength accumulation effect; the effect of the Verdet constant is the greatest, that of the Reflection-Induced-Retardance is intermediate, that of the linear birefringence is the smallest.

仿真结果表明，通过和其相应的单色光模型输出的对比，在研究对象相应参数的具体范围内：波长积累效应对系统输出的影响相对于单色模型输出来说很小，小于10~(-4)，因此在实际研究中采用单色模型是合理的和可行的；在总的波长积累效应中，宽带系统输出与单色模型输出的差距随着待测电流的增大而减小，而且影响最大到最小的因子依次是Verdet常量、反射相移和线性双折射。

In order to make the current grade-determination method of the cultivated land more rational, the paper has analyzed the natural and social economic factor of cultivated land quality deeply. Many ideas, including the theoretical foundation on grade-determination, the authenticity of the basic materials, the division of the index district, the determination of the appointed crops and their parameters , the largest theory output of the crop and the definition of the suitable range about index district, the control of the equivalence district in the county , the revision of the multiple crop index and the application of GIS ,etc. have been deeply discussed, and the current grading model of the cultivated land has been revised.

为使现行耕地分等方法更趋合理，本文以耕地质量评价的相关理论为基础，强调了基础资料对等别划分的重要性，明确了获取方法，并对指标区的划分、指定作物及其参数的确定，作物理论最大产量及其适用范围的界定，县域范围内等值区的控制，土地利用系数的修正、复种指数的修正和GIS在耕地分等中的应用等方法进行了深入探讨，修正了现行耕地分等模型。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
