The conformation of disulfide bonds, secondary structures, crystallinity and α-crystallinity of the cashmere fiber are changed after the cashmere yarn is steamed above 120℃ in relaxed and stretched state or crabbed at 98 ℃, 130℃ for different time, which is firstly found out. These structure changes of the treated cashmere fiber are related to temperature, time, and moisture content and tensile during heat treatment.

However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.

但极低的锰含量、相对较高的锶含量和包裹体均一化温度等资料均不支持有94%的大气淡水参与了结晶白云岩的白云石化作用，其白云石化流体应是埋藏成岩过程中囚禁的近同期、但是非同期的海源流体，其来源可能与埋藏成岩过程中该时间段蒸发盐的溶解有关。

In general, the traditional characteristics of Chinese films are as follows: the formula for artistic creation is dominated by realism; the ideographic method is inclined to conveyimplications; the narrative technique is characteristically an integrated story; the portrayal of the charaters' fate is based on dramaticism;the golden mean promotes moderate and implicit emotional exp ression; the ideology holds philosophical and instructional significance.

中国电影是我们这块土地黄皮肤子民的文化结晶，它的血液中流淌着民族挥之不去的深刻印记，搜捡中国电影艺术表现上的隐显标记，有助于现代电影的健康发展。就总体而言，中国电影传统特征包括以下几个方面：以现实主义为主导的艺术创作方法；言外之意的表意方式；追求故事完整统一的叙事性特点，以戏剧性为基础的人物命运塑造；中庸为度、节制含蓄的惰感抒情特征；充满哲理教化目的的思想倾向。

On the other hand, with low process temperature and high Ar flow, the structure is amorphous due to significant energetic particle impingement and less diffusion energy by substrate heating. Phase transformation through process heating and post heat treatment were also discussed.

特别的是，利用高温镀膜制程(550~600aC)及低Ar气体流率(10~15 s.c.c.m)之制程控制，可使结构形成结晶状态，相反地，若使用低温镀膜制程(500~550aC)及高Ar气体流率(15~20 s.c.c.m)之参数控制，则使结构偏向非晶质化。
