帮忙翻译一下吧。谢谢啦！！！

3.Fluxing – There are many kinds of flux. They vary in the way they “wet” the solder when it flows and in their protective qualities for keeping firescale off the metal. For silver soldering, white paste flux is a good choice. It holds up well and will allow the solder to flow easily. White Paste Flux is a mixture of mostly borax and water. It protects the surface of the metal from oxidation during the heating process. Flux must be used wherever solder is to flow.Flux is also an indicator of temperature. The flux becomes glassy at approximately 1200o F. Flux should be "pasty" in consistency. If needed, add distilled or purified drinking water - but do not use tap water - the mineral content is too high and the flux will not keep the metal clean. Overheating or prolonged heating will make the flux breakdown. Flux can also serve as an “insulating” material – that needs to be taken into account when considering
how the metal is heated.
4.Heating the Metal - The pieces of metal being joined should reach the flow point of the solder at the same time. Begin by using the "brushy" part of the flame to heat the areas adjacent to the joint. Once the flux becomes "glassy”, center-in on the solder joint by moving the flame closer (approximately 1" from the light blue cone) andheating directly on the joint in addition to continuing to heat the surrounding metal. Be sure to take size, heat sinks, and metal alloy into consideration when deciding where to heat. Solder will flow toward heat. On long solder joints, the solder can be drawn down a joint by heating the joint in front of it. When soldering an enclosed hollow area, provide an escape for steam and gasses. These expand rapidly during the heating process, and if not vented, can cause the piece to "explode".

3。稀释许多种类的通量。他们有他们的方式“湿”的焊料流动时，在保护他们的素质让红斑从金属。银钎焊熔剂，白是一个不错的选择。它拥有和将允许焊料容易流动。白浆流量是主要的硼砂和水的混合物。它保护金属表面氧化过程中的加热过程。必须使用流量在焊料是流量。流量也温度指示器。通量约1200oF.通量变玻应该是“馅饼”的一致性。如果需要的话，加入蒸馏水或纯净水，不要用自来水-矿物含量太高，流量不会保持金属的清洁。过热或长时间加热会使流量故障。通量也可以作为一个“绝缘”的材料–需要综合考虑多金属加热.4.加热金属-金属片的连接应同时达到焊料的流动点。开始使用火焰的“毛茸茸”部分加热的邻近地区的联合。一旦通量变“玻璃”，中心在焊料通过移动火焰接近关节（约1“从浅蓝色锥）含量直接在除了继续加热周围的金属接头。一定要大，散热片，和金属合金考虑决定在哪里热。焊料将流向热。在漫长的焊点，焊料可以被一个共同的在它前面的接头加热。当焊接封闭的中空区域，提供蒸汽和气体逃逸。这些迅速扩大在加热过程中，如果不通风，使片”探索 望采纳

稀释——有许多种类的通量。他们也有他们的方式“湿”当它流的焊料,在保护性的品质firescale保持了金属。银钎焊,白色膏通量是一个不错的选择。它能支撑好,将允许焊料流动很容易。白色膏通量是一个混合的大多是硼砂和水。它能保护金属的表面氧化在加热过程。通量必须使用无论焊料是流。通量也是一个指示器的温度。

加热金属-金属结构件的加入应该到达流点的焊接在同一时间。首先使用“毛茸茸的“部分的火焰加热的区域毗邻接头。一旦通量变得“玻璃”,中心在焊点上通过移动火焰接近(大约1英寸淡蓝色锥)andheating直接在联合除继续加热周围的金属。一定要大小、散热器、金属合金考虑当决定在哪儿
