The popular latex band and tube , for example , are strong pulling force , its expansion rate up to eight times or more , it is hard to broken , the bright colour never fades with non - toxic to human health . our products have been meeted the en - 71 , sgs and strength character test etc . we exported to the global market for more than 10 years with the turnovers about usd 2 , 000 , 000 each year 主要产品系列有运动面具宠物玩具等其它各种相关乳胶制品系列。本厂的乳胶制品不易老化耐用色泽鲜艳不易褪色不易裂有着极优的伸展力和恢复力所有的产品都经en - 71和拉力测试环保检验合格。
The article structure the landslide prevention and cure , the structure of prestress anchors and its application in detail . basing on the geology condition of fabricating yard , we calculate the solid power and the length of anchor rope . we have worked out the experiment research scheme , and has carried on the earlier stage experiment , field demarcation experiment and has opened pulling the experiment on the spot . ten teams of steel rope to two teams of structure types twist the experimental data that thread internal stress and the total pulling force has been in progress research , and has put forward raising the measure of solid capability of prestress anchor and administering possessing 本文以川藏公路滑坡路段为研究对象，对滑坡的治理、预应力锚索的结构、作用及其在滑坡防治中的应用进行了详细的分析；基于施工现场的地质条件，对锚索锚固力及锚索最佳锚固段长度进行了理论计算；制定了实验研究方案，进行了前期实验、现场标定实验、实地张拉实验；对两组结构型式的十组钢绞线内应力及总张拉力的实验数据进行了研究，提出了提高预应力锚索锚固性能的措施，以及具体的施工方案和施工工艺。
The anchorage in rock and soil is a technology which strengthen structure , rock and soil . anchor bar strengthen rock or soil tightly by pull force which is provide by the shear strength between anchor bars and rock or soil . anchor technology has more obvious advantage than traditional method which strengthen rock and soil by the strength and gravity of rock or soil ownself 岩土锚固技术是通过埋设在岩土体中的锚杆，将结构物与岩土体紧紧地联锁在一起，依赖锚杆与岩土体的抗剪强度传递结构物的拉力或使岩土体自身得到加固，以保持结构物和岩土体的稳定。
Small and medium enterprises should perfect their technical innovation mechanism from the five aspects of market pushing and pulling forces , technical pulling force , entrepreneurs , the guiding policies of the government and the corporate motivation policy , choose their technical innovation strategy from the two dimensions of the market and technology , and select their path of technical innovation from the two dimensions of market growth capacity and technological growth capacity in light of their own characteristics 中小企业应该从市场推力与拉力、技术拉力、企业家以及政府的指导政策与激励政策等五个方面完善技术创新机制，从市场与技术两个维度选择技术创新战略，依据自身特点从市场增长能力与技术增长能力两个维度进行技术创新的路径选择。
The diabetes coronary heart disease high reason of incidence of a disease is many - sided , yet chiefly is the fat supersession chaos , and creates glycerine three grease and the cholesterol to get higher , that sweet and protein are metabolized oddly be able to create myocardium capillary pathological changes and the myocardium supersession chaos , but the flora nervous system chaos easily arouses that blood vessel pulling force adds and injures the artery breastwork 糖尿病冠心病发病率高的原因是多方面的，但主要是脂肪代谢紊乱，造成甘油三脂和胆固醇增高，糖和蛋白质代谢的失常会造成心肌的微血管病变和心肌代谢紊乱,而植物神经系统紊乱易引起血管张力增加而损伤动脉壁。
