 If PV orientation is not perceived as a design restriction, architects will be much more open to their use.
 Using oligo (dT)12～18as primer and mRNA from porcine pituitary gland as template, the first strand of cDNA was synthesized by AMV reverse transcriptase; and then the second strand of cDNA was replicated by E. colt DNA polymerase I after cutting mRNA into oligonucleotides with RNaseH. The full-length of double strand cDNA was thus obtained with further treatment by E. colt DNA ligase and T. DNA polymerase. On the basis of the known DNA sequence for porcine growth hormone, a pair of specific primers were designed... Using oligo (dT)12～18as primer and mRNA from porcine pituitary gland as template, the first strand of cDNA was synthesized by AMV reverse transcriptase; and then the second strand of cDNA was replicated by E. colt DNA polymerase I after cutting mRNA into oligonucleotides with RNaseH. The full-length of double strand cDNA was thus obtained with further treatment by E. colt DNA ligase and T. DNA polymerase. On the basis of the known DNA sequence for porcine growth hormone, a pair of specific primers were designed and synthesized. Subsequently, polymerase chain reaction for amplifying the sequence encoding mature porcine growth hormone was conducted using these primers and synthesized template. Electrophoresis and southern blotting showed that the amplified fragment by PCR was the unique DNA sequence of mature porcine growth hormone,flanked by designed restriction site and codon sequences. 以猪垂体ｍＲＮＡ为模板，Ｏｌｉｇｏ（ｄＴ）（１２～１８）为反转录引物，在ＡＭＶ－ＲＴ的催化下，先合成ｃＤＮＡ第一链，再以ＲＮａｓｅＨ降解的ｍＲＮＡ小分子为引物、ｓｓ－ｃＤＮＡ为模板，在Ｅ．ｃｏｌｔＤＮＡＰｏｌ．Ｉ的催化下合成ｃＤＮＡ第二链，并用Ｅ．ｃｏｌｉＤＮＡｌｉｇａｓｅ连接缺口和Ｔ４ＤＮＡＰｏｌ补齐末端，以获得长度完整的ｄｓ－ＣＤＮＡ分子。根据已知的ｐＧＨ基因序列，设计并合成了一对特异引物分子，以总ｃＤＮＡ为模板，进行ＰＣＲ扩增，分子杂交证明，获得的扩增片段即为侧翼带有重组位点和附加密码的编码ｐＧＨ成熟肽的ＤＮＡ序列。 From the summary of the advantages and disadvantages of some curved route design thoughts and methods based on splines,this paper presents the design method based on cubic geometrical splines for "transition-circle-transition"combination form usually used in horizontal alignment design of interchange ramps,which gives full play to characteristics of cubic geometrical splines' smooth and continuity,simple calculation and correspondence with horizontal alignment,establishes relations between... From the summary of the advantages and disadvantages of some curved route design thoughts and methods based on splines,this paper presents the design method based on cubic geometrical splines for "transition-circle-transition"combination form usually used in horizontal alignment design of interchange ramps,which gives full play to characteristics of cubic geometrical splines' smooth and continuity,simple calculation and correspondence with horizontal alignment,establishes relations between initial spline curves (indicating design restrictions and ideas for alignment location) and alignment's combination forms and parameters,converts automatically splines into horizontal alignments. 本文在总结目前一些基于样条的曲线形设计思想和方法优缺点的基础上，针对立交匝道平面线形设计中经常遇到的“缓──圆──缓”组合形式，提出了基于三次几何样条曲线的线形设计计算方法，充分发挥样条曲线光滑连续、计算简便、与平面线形相一致的特点，建立了初步样条曲线（反映线位约束条件和布线设想）与线形组合形式及参数之间的依存关系，实现了样条曲线向平面线形的自动转化。该方法对开发高效的正交ＣＡＤ系统具有重要意义。 ln terms of the method of multiple scales in nonlinear oscillations, superharmonic and subharmonic resonance' s of hydrogenerator rotors caused by unbalanced magnetic pull are discussed when both mass and assembling eccentric of the rotors are taken into account.

Considering nonlinear properties of the unbalanced magnetic pull, such phenomena are discovered that if the critical speed of rotors is close to 2 or 3 times as much as the rotary speed, the superharmonic resonance occurs, and as the same way if the critical speed is close to 1/ 2 or 1/3 times as much as the rotary speed, the subharmonic resonance occurs, too. Correctness of conclusions from the theoretical analysis is verified by model experiment results and new design restrictions for the hydrogenerator rotors are suggested simultaneously. 本文利用线性振动理论的多尺度方法，分析了水轮发电机转了同时存在安装偏心和质量偏心时，不平衡磁拉力引起的超／次谐波共振现象，考虑到不平衡磁拉力的北线性后，发现当临界转速接近于２倍或３倍工作转速时，会出现超谐波共振：同样，若临界转速接近于１／２倍工作转速或１／３倍工作转速时，会出现次谐波共振。通过模型试验，验证了理论分析的正确性，同时提出了水轮发电机转子设计的新准则。 << 更多相关文摘
