Commonly used as stem materials in pressure-rated valves, silicon bronze has greater resistance to stress corrosion cracking than common brass es.

通常在压力等级阀门中作为阀杆材料使用。在防止金属超压力引起的腐蚀造成的断裂方面，硅青铜比常见的黄铜具有更好的性能。

After the treatment, seed vigor is similar to control or even higher than control, without any harmful symptom.

适度超干后种子活力与对照相似甚至比对照高，未出现受伤害的症状。

The method solves the problems better through adopting the following technical proposal that: the method takes the solid super acid consisting of the VIB group elements or the VIB group elements and the IVB group elements in the periodic table of elements and loaded on a symbiosis molecular sieve as catalyst, and naphtha with the component being C4-C10 as a raw material so as to carry out catalytic cracking reaction at a temperature of between 550 and 700 DEG C, under a pressure of between 0.01 and 0.5 MPa, at a reaction weight space velocity of between 0.1 and 4 hours and with the weight ratio between water and naphtha of between 0.5:1 and 4:1, thereby generating ethylene and propylene.

本发明涉及一种催化裂解制乙烯丙烯的方法，主要解决现有催化裂解制乙烯丙烯催化剂的使用温度高，活性低，乙烯丙烯选择性差的问题，本发明通过使用在共生分子筛上负载由元素周期表VIB族元素或VIB族元素和IVB族元素组成的固体超强酸作为催化剂，以组份为C 4 ～C 10 的石脑油为原料，在反应温度为550～700℃，反应压力为0.01～0.5MPa，反应重量空速为0.1～4小时-1 ，水/石脑油重量比为0.5～4∶1的条件下，进行催化裂解反应生成乙烯丙烯的技术方案，较好地解决了该问题，可用于催化裂解制乙烯丙烯的工业生产中。

They have only scored in three of the last nine games and have netted only nine goals in front of their home fans - the joint lowest total in the Premiership along with Birmingham.

The pop-idol field - like every field that can lead to super-fame - is more crowded than it has ever been, and the variety of routes to stardom keep growing. When the Beatles were on "The Ed Sullivan Show" in 1964, more than 70 million people watched, that is, more than one-third of the entire population of the United States.

流行偶像领域（像所有领域一样可以聚集超旺人气）比以往更加拥挤，成为大明星的途径也开始花样翻新。1964年甲壳虫乐队首次在艾德苏利文剧场开演唱会时，超过7千万的歌迷前来观看，这相当于美国总人口的三分之一还有多。

对于中等光滑度的纸张来说，电子油墨比平版制卡和会员卡制作墨更有优越性，但是平版制卡和会员卡制作墨在超平滑纸张领域更具有优越性。

Among New York's fashionable and ultra-exclusive clubs, the St. James stood an acknowledged leader--more men, perhaps, cast an envious eye at its portals, of modest and unassuming taste, as they passed by on Fifth Avenue, than they did at any other club upon the long list that the city boasts.

电子书简介：在纽约的时尚和超专属俱乐部，圣詹姆斯站在一个公认的领导者-更多的人，也许，在其门户网站的一投羡慕眼睛温和，谦逊的味道，因为它们通过在第五大道的，比他们在任何一长串后，我们的城市拥有许多其它俱乐部。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
