趋势减少型为我国山地森林群落植物物种多样性变化的主要形式，其中再区分为大兴安岭北部山地、小兴安岭、长白山、马衔山、西天目山、幕埠山、洞宫山、百祖山、南鹫峰山、九龙山、凤阳山、万洋山、八大公山、鹤峰山、七星山、梵净山、雷公山、昆明西山、金佛山、哈巴雪山、镇康大雪山等平稳减少型；黄山、化龙山、神农架、都庞岭、九连山和武夷山地、点苍山、西双版纳低山地等波动减少型，这些山地存在轻度的"中等高度的膨胀"现象，但东北地区的山地、浙闽粤低山丘陵区的大部分山地、湘西、鄂西和川黔交界区山地的"中等高度的膨胀"现象不甚明显

By the use of Circling cluster and Envlopment theory and flat surface sit-mark transformation theory, the chain wheel tooth equation of roller chain at high speed to match conjugage engagement is deduced.Establishing chain speed equation of roller chain at high speed,based on the analysis of the speed curves between roller chain at high speed and common roller chain,good drive of roller chain at high speed is verificated theoretically.By a example that move distance from transverse vibration between roller chain at high speed and common roller chain is contrasted,the accuracy of those theories that the paper brings up and higher functions of roller chain at high speed is proved.Finally, Establishing conjugage engagement line equation of roller chain at high speed and analyzing the complete engagement zone, the chain wheel tooth curve equation is studied at a higher degree. At the same time,the lack's place of the research result is pointed out.

依据高速滚子链设计要求与H_y-V_0齿形链的研究，阐述了滚子链传动实现准共轭啮合理论可能性；利用圆族包络法结合平面坐标变换理论推导出了满足共轭啮合的高速滚子链的链轮齿廓曲线；建立起高速滚子链链速方程，通过对高速滚子链与普通滚子链链速曲线的对比分析，从理论上验证了高速滚子链具有良好的传动性能；最后，建立起高速滚子链共轭啮合线方程，对其整个啮合区间进行了分析，进一步研究了链轮齿廓曲线方程，确定了主要参数的设计方法的问题，并同时指出了不足之处。

Zhejiang permanent Machinery Group of China is the sole approved by the State Economic and Trade Commission of the Chinese chain export base, the company under the seven plants, Seiko produced "CHJC","permanent" licensing standards and chain of more than 10,000 kinds of non-standard specifications (specifications Precision sleeve roller chain, the chain plate, flat-top chain, silent chain, Shu Songlian, the Agricultural Machinery chain, chain oil, metallurgical use chain, motorcycle chain, speed chain, sprocket, coupling ......).

浙江恒久机械集团是中国唯一经国家经贸委批准的中国链条出口基地，集团公司下属七个分厂，精工制作"CHJC"、"恒久"牌标准和非标准链条10000多种规格（各种规格的精密套筒滚子链、板式链、平顶链、齿形链、输送链、农机链、石油链、冶金用链、摩托车链、倍速链、链轮、联轴器。。。。。。）。
