In view of the above factors, to a certain extent, affected the greenhouses of the application and promotion, plus the current bamboo, wood steel prices rising, the vast rural areas in urgent need of a low-cost, corrosion-resistant, resistant to moisture, anti-aging a new framework to shed Instead of the traditional bamboo, wood, steel materials, in the light of this, I units commissioned by the relevant departments, research institutions and the parties concerned under the guidance of experts, completed a "no-pillar greenhouses skeleton of" key project, supported by aircraft I developed a special formula units, the production of greenhouse skeleton without pillars of quality and cheap, quality higher than that of a steel frame, lower than the cost of bamboo, wood, the technical supervision departments test, the main performance indicators are as follows: the simulation of the actual scope: 5.8 - 6.8KN bending strength ≥ 3.3 KN compressive strength ≥ 20 KN water absorption ≤ 13

鉴于上述因素，在一定程度上影响了塑料大棚的应用与推广，又加之目前竹、木钢材价格不断上涨，现广大农村急需一种价格低廉、抗腐蚀、耐潮湿、抗老化的新型大棚骨架来代替传统的竹、木、钢材料，鉴于此，我单位受有关部门委托，在各方科研机构及有关专家的指导下，完成了《无支柱塑料大棚骨架机》的攻关项目，该机配以我单位研制的特殊配方、工艺生产的无支柱大棚骨架质优价廉，质量高于钢架，成本低于竹、木，经技术监督部门测试，主要性能指标如下：模拟实际受力范围：5.8-6.8KN 抗折强度≥3.3KN 抗压强度≥20KN 吸水率≤13

The hygienic and toxinfree Xinli PP-R pipes serial products are green and environmental construction materials, which have been recommended by the four ministries and commissions of the State Department, The products are heatresistant which means that the temperature of the supplied water can reach 95℃ under the specified long-term working hours, They are also corrosion-resistant and antiscale and can prevent any corrosion and rust in pipes, lavers and bathtubs.

&鑫利&PPR给水管系列产品，质量轻，20℃时的密度为0.89—0.91g/cm3，重量仅为钢管的九分之一，紫铜管的十分之一。由于重量轻，可大大减轻工人的施工强度。耐热性能好：瞬间使用水温可达95℃，长期使用时，当工作压力不大于0.6mpa时，水温可达75℃。这可满足一般生活、生产水温的需要，所以建筑给水PPR管一种较理想的热水管材。耐腐蚀性好：对水中的所有离子和建筑物内的化学物质均不起化学作用，不生锈、不会腐蚀。

On the other hand,it is demonstrated that pitting sensitivity of Al-6Mg-Zr-Sc alloy in the SRB solution is decreased and its microbiologically influenced corrosion r.

结果表明，添加Sc元素后，合金的氧化膜更加致密，具有更好的保护作用，使电极开路电位正移100 mV左右，同时Sc元素的加入降低了材料在SRB菌液中的点蚀敏感性，使材料耐微生物腐蚀性能得到提高，但是添加Sc后的合金对SRB更加敏感。

The advantages of Fluorphlogopite Mica are: good penetrativity of light and wave; long time operation at the temperature up to 1100°C; anticorruption of strong acid and alkali and nocuous gases; almost no loss in high frequency medium; 2000-time-smaller vacuum deflation at high temperature than inartificial mica while 1000-time-higher body resistance than inartificial mica.

氟晶云母优于其他云母的关键点在于：优秀的光、波透过率；可长期在高达1100℃的高温环境下工作；抗强酸、强碱及有害气体的腐蚀；在高频介质环境下基本没有损耗；高温真空放气量比天然云母小2000倍，体电阻率比天然云母高1000倍。氟晶云母是替代天然云母、聚四氟乙烯、石英玻璃等低性能材料的新型耐高温、高频、绝缘材料。

In acid and salt solution,TiN shows an excell ent corrosion resistance after 100 h immersing test.TiN coating acted as a physi cal barrier between the stainless steel and corrosion media.The corrosion proces s initiated from the pinhole and the corrosion process under the coating is very similar to the pit corrosion form.

结果表明：TiN涂层可以提高材料在中性和酸性溶液中的耐蚀性能，TiN涂层的保护机制为物理屏障作用；镀层的微观结构缺陷是涂层失效的主要原因，涂层下金属的腐蚀行为与孔蚀类似。

Corrosion of carbon steel and the weathering steel in marine atmosphere during different time was compared,the morphology of rust layer was observed,and the distribution of the alloy elements in the rus t layer was determined.

张全成，吴建生，陈家光摘要：测量了碳钢和耐候钢在上海地区大气中的腐蚀速率，分析测定了锈层的相组成以及合金元素的分布。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
