The progresive regressing and regressing were made on the fruit production to the parameter of tree framework of gold delicion / M9 / Shandingzi in 6 years old based on the date of yeild investigations and measurment. By the marginal analysis and fuzzy clasification.These parameter were defined that trunk circumafename= 24.93cm, highth of tree=2.5m,average width ot tree=2.5m,size of tree=5.05～5.6m~3, number of length branch / per tree = 101-161.number of middle branch / pe...

本文以金冠/M9/山定子6年生树体为试材，对树体结构参数进行田间测定，用多元回归、逐步回归的方法分析出十种树体结构指标对产量的效益，用边际分析的方法和聚类的方法研究出金冠/M9/山定子产量最高时树体结构参数为：干周=24.93cm，树高=2.5cm，平均冠径=3.01m，冠高=2.5m，树冠体积=5.0～5.6m~3，单株长枝数=101～161个，单株中枝数=122—142个，单株短枝数=601～616个，单株枝量=847～903个，单株叶面积=13.5m~2。

Polyethylene gas pipeline had many outstanding features, which successfully solved the two major traditional pipeline corrosion and joint leakage problems. But the lower mechanical strength was the main drawback, and minimum required strength was one of the key index to measure pipe performance of long-term use.

聚乙烯燃气管道具有的许多卓越特性，圆满地解决了传统管道的腐蚀和接头泄漏两大难题，但机械强度较低是其主要缺点，长期静液压强度是衡量PE管材长期使用性能的主要指标。

And everyone else--the klutzes, the shy, the gymimpaired--people who saw in PE a particular brand of frustration and bondage never again to be repeated in life

而另外的那些人----是些笨手笨脚的、文静害羞的、不擅体育的人----他们把体育看成一生中永远不会再重视的一种特殊类型的挫折和束缚。

This beautiful Bayonet Knife was designed for use on the renowned PE-57 (the Rolls Royce military rifles), made by the firm Schweizerische Industrie-Gesellschaft.

这个美丽的刺刀刀是专为著名的体育用途- 57军用步枪，由公司瑞士工业弗劳恩霍夫协会的进展。

The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.

本文分析认为，水树枝中的离子型空间电荷在几种电压共同作用下会发生周期性振动，这种振动会促使水树枝中的导电离子在较低的叠加电压激励下进入连接水树枝微孔的微裂纹，微裂纹导通不仅导致水树枝的电导发生变化，而且在检测回路中会有水树枝老化超低频特征信号电流产生。
