The relations of inducing skin current of shielding layer, core voltage and core current with the environment field were obtained. The change of shield layer current wave with grounding state of external shield and core voltage with loading resistance was analyzed. According to the dependence of shield layer current oscillating frequency on electromagnetic wave propagation velocity, conception of transporting line of shield layer-ground with equivalent relative dielectric constant was presented. fited equation of equivalent relative dielectric constant with change of cable height was given.

试验得到九芯电缆屏蔽层感应电流、芯线感应电压、芯线感应电流以及环境场之间的关系；分析了皮电流波形随外皮接地状态的变化，芯电压随负载电阻的变化；基于皮电流振荡频率与电磁波传播速度的关系，提出了屏蔽层-大地"传输线"等效相对介电常数概念，给出了等效相对介电常数随电缆高度变化的拟合式；皮电流计算与测量结果在波形、振荡周期、衰减规律等方面有较好的一致性。

I can still remember The "Triple Stars Fish Balls" in the center Market of my city,the outside skin of which mixture fish meat and pachyrhizus powders and shark meat is comminuted inside.When keeping them in boiled meat soup for minutes,the fish balls begin to expand and appear like big snow balls and have elasticity.

我还记得我们中心商场里的的那家&三星鱼丸&，丸子的外皮是用鱼肉泥加地瓜粉混合做成的，里头就是由用鲨鱼肉绞烂的馅填充，放进沸腾的的肉汤里过几分钟后，鱼丸就开始变大了，白白胖胖的像雪球一样，又特别有弹性。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
