The organic saponifier often is composed of alkaline amines. Some common limitations are the potential attack of the solder joint, chemical oxidation that reduces bath life, limited effectiveness on some of the new flux compositions, and a contributor to the VOC content.

有机皂化剂一般由碱性胺组成，其主要的局限性在于可能对焊点造成腐蚀，并发生氧化反应降低焊剂清洗寿命，另外，它对某些新型焊剂清洗效果欠佳，VOC排放量较高。

This paper compares the agglomerated flux with fused flux ,and introduces the usage and production technology process of agglomerated flux.

对比了烧结焊剂与熔炼焊剂的区别，从中介绍了烧结焊剂的使用特点和生产工艺流程

A new type of agglomerative flux for high speed submerged arc welding is developed,its welding speed can reach 80 m/h or even higher.

研制了一种新型的焊速可大于80m/h的高速埋弧焊烧结焊剂，并介绍了这种焊剂的性能。

They cannot detect a nonwetted joint if the correct volume of solder does exist in the path of the beam, even if there is a gap between the solder on the lead and the solder on the land.

他们不可能查出一个不潮湿的联接，如果焊剂的正确容量存在于射线的道路，即使有焊剂在主角和焊剂之间的一个空白在土地。

If fluxed parts are allowed to stand, the water in the flux will evaporate, and dried flux is liable to flake off, exposing metal surfaces to oxidation.

假如答应涂上焊剂的部件处于竖立状态，那么焊剂中的水分会蒸发掉，而干燥的焊剂很轻易脱落，致使暴露的金属表面轻易被氧化。

If fluxed parts are allowed tostand, the water in the flux will evaporate; and dried flux isliable to flake off, exposing metal surfaces to oxidation.

如果允许涂上焊剂的部件处于直立状态，那么焊剂中的水分会蒸发掉，而干燥的焊剂很容易脱落，致使暴露的金属表面容易被氧化。

If fluxed parts are allowed tostand, the water in the flux will evaporate, and dried fluxis liable to flake off, exposing metal surfaces to oxidation.

如果允许涂上焊剂的部件处于直立状态，那么焊剂中的水分会蒸发掉，而干燥的焊剂很容易脱落，致使暴露的金属表面容易被生日配对缘分测试氧化。

If fluxed parts are allowed to stand, the water in the flux will 耐腐蚀液下泵, and dried flux is 不锈钢软管型号 to flake off, exposing metal surfaces to oxidation.

如果允许涂上焊剂的部件处于直立状态，那么焊剂中的苏泊尔电磁炉会蒸发掉，而干燥的焊剂很容易脱落，致使暴露的金属表面容易被氧化。

If allowed to painted components in the vertical flux of the state, then the flux of water vaporizes out, and dry Flux easily fallen off, causing the exposed metal surface vulnerable to oxidation.

如果允许涂上焊剂的部件处于直立状态，那么焊剂中的水分会蒸发掉，而干燥的焊剂很容易脱落，致使暴露的金属表面容易被氧化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
