2.座位可调控，座椅的前后可调，适应不同的人群舒适使用
3.能存储电能，在健身运动的同时，将电能存储在电池中，电池输出的电压为直流15V

摘 要
中国健身器材行业的发展始于20世纪80年代末，随着中国加入WTO和北京申奥的成功，为健身器材行业的发展提供了有利条件和发展机遇，健身队伍的不断扩大为健身器材生产商带来浓厚商机。
中国健身器材行业在迅速发展的同时，一些问题也日益显露出来。特别是在国际市场缺乏知名品牌，产品附加值较低，同时，与国际先进水平相比，中国不少生产企业还处在仿制生产阶段，产品研发和技术创新能力不足。在消费领域，与欧美等发达国家相比，健身器材产品在家庭的普及率及用于健身运动的人均消费还很低。
因此，中国健身器材工业企业必须抓住新的发展形势，加大科技创新，努力提高产品质量，加强自主研发能力，有关部门应尽快制订出健身器材统一的技术安全标准，加强售后服务。只有这样才能在新形势下立于不败之地。它们的主要功能是：增加臂力：哑铃?握力器 多功能仰卧起坐板
划船器：主要用来增强手臂力量、背阔肌和动作协调能力。
AMT体适能运动机：与其他的健身方式不同，用户可以在不同的运动模式和完全零冲击体验下，类似于登楼梯、步行、慢跑和长跑间自由转换。您可以通过这种即时转换模式功能，调整您的训练模式来达到针对特定肌肉群训练的目标。
椭圆运转机：平滑流畅的运动轨迹和交叉坡度专利技术让使用者以符合生物力学的姿势锻炼肌肉组，增加了锻炼的多样性和有效性。零阻力的锻炼减少肌肉劳损的发生。
健美车：锻炼时，象骑自行车一样，主要用来增强腿部力量，增强心血管功能。
健步车：主要用以锻炼腿、腰、腹部肌肉及心肺功能。
跑步机：主要用以锻炼腿、臀、腰、腹部肌肉及心肺功能。
美腰机：可对腰部、背部作放松按摩。
综合型多功能器：一般都包括扩胸器、引体向上、仰卧推举、仰卧起坐等器械的功能。扩胸器、引体向上、仰卧推举，主要是用来锻炼上肢力量及胸大肌力量；仰卧起坐，主要用来锻炼腰肌群，减少腰腹部多余脂肪。

Abstract
The development direction of harvester will be to high-tech direction, making out the applicability of harvester is the development of the market, is very promising for different regions developed different harvester. Thus, the corresponding manufacturing combine high performance is the development of foreign harvester. The rice combine harvester can complete harvesting, threshing, separation and bagging operations at one time. The machine has the advantages of small volume, light weight, flexible operation, through and good adaptability, can better solve the problem of big, medium-sized harvester to harvest in the hilly, mountainous and paddy field. Thus, the corresponding manufacturing combine high performance is the development of foreign harvester. The rice combine harvester can complete harvesting, threshing, separation and bagging operations at one time. The machine has the advantages of small volume, light weight, flexible operation, through and good adaptability, can better solve the problem of big, medium-sized harvester to harvest in the hilly, mountainous and paddy field.Thus, the corresponding manufacturing combine high performance is the development of foreign harvester.
