The rules of the cold-test characteristics changing with helix pitch are also studied and it turns out that, with increasing helix pitch, the phase velocity increases linearly, the interaction impedance changes nonlinearly and the attenuation constant decreases nonlinearly. At the same time, with the limitation of the synchronism between the electron beam and the electromagnetic wave, the change of pitch is small and therefore an approximate linear relation can be introduced.

研究表明：相速几乎随螺距增大而线性变大，互作用阻抗与螺距是非线性的关系，衰减常数随螺距增大而非线性地减小；由于在维持电子注与电磁波速度同步的限制下，螺距变化的幅度不可能很大，因此可近似按线性关系来处理互作用阻抗及衰减常数与螺距之间的关系。

In the light of cost index and pollution degree, the characteristics of kinds of pulp are analyzed in detail, and the GP pulp which is low cost, high-yield, no-pollution is chosen as the material of tableware. Based on material element analyzed, shaping technology is designed, the to and for single plane shaping equipment which is high shaping quality, high production efficiency and is easy to automatize is chosen. All kinds of measure are taken to solve the problems which are inequality in the shaping process of GP pulp, and dosage which matches with GP pulp is chosen. Some ways of fixing shape and heat up are analyzed, the technology of saving energy of heat pressing to fix shape being composed of oil heat and only one fixed shape in the mold is applied, with which it is high production efficiency, low cost to fix shape effectively, which saves energy 30 percent. In order to make the production line meet with material of GP pulp, measure are taken to solve the problem of pulp adhered to netlike molding which can lead to carry material difficult, the structure of fully automatic equipment is renovated, the loaded beam is optimizationally designed to make equipment structure compactand improve location precision and products quality. According to technologic flow and actual characteristic, Omron PLC is chosen as the core of the control system, proximity switch as detect unit take the place of touch switch, software is designed reasonably according to time order figure, hardware is simplified, the reliability of system is advanced, the stability of system is assured to make production order. Intelligence neuron PID system is studied theoretically which is made up of both neuron with self-organizing and self-learning function and ordinary PID with the characteristic of the simple structure and high stability, which can automatically tune the parameter with the change of system parameter, remain perfect performance.

Literature Research The etiological factors of POF are not still clear. The changes of sites and numbers in X chromatosome, X; autosome translocations, a forkhead transcription factor gene (FOXL2) mutations, FRAXA premutations and inhibits gene mutations are found in POF patients, so genetic disorders have been thought to be involved. Irradiation, chemotherapy or pelvic operations can damage ovaries and cause ovarian atrophy and failure, so it is thought one factor of POF.

一、文献研究 POF的确切病因目前尚不清楚，从POF患者体内检测到X染色体上位点和数目的变化，X染色体与常染色体间的平衡易位，脆性X基因前突变，FOXL2基因突变，抑制素基因突变等，故认为POF发生与遗传因素有关；由于放射、化疗或盆腔手术等可损伤卵巢，导致卵巢萎缩，出现卵巢衰竭，故也是导致POF的因素之一。

Electrical stimulation of NA had no effects on gastric volumes, titratable acidity, acid concentration, but elicited a badly pronounced increase in the total bicarbonate, as well as restraining of respiration and inducing sinus bradycardia. But electrical stimulation of DMV produced a badly significant increase in titratable acidity, and pronounced an evident increases in gastric volumes and acid concentration, as well as restraining respiration and inducing sinus bradycardia.

But the simple fact of the matter is that the political conversation, which shifts from time to time, has shifted anew, and for the foreseeable future Americans will be more engaged with questions about how to manage a mixed economy than about whether we should have one.

但是，这个简单的事实却是说明了一直在变化的政治对话，现在已经开启了新的方向，在可预见的将来，美国的任务将处理怎样掌控好一个混合经济，而不是要不要采用这种混合经济模式。
