B Dip a clean nichrome wire/platinum wire to concentrated hydrochloric acid.

把清洁的镍铬线/铂丝轻轻浸於浓氢氯酸中。

The open wire heating elements are usually made of nichrome wire.

裸线式电热元件通常用镍铬合金丝制成。

The open ribbon elements are also made of nichrome wire and are insulated in the same manner as the open wire elements.

裸带式元件也和裸线式元件一样以镍铬合金丝制成并以同样方式绝缘。

Procedure: Use concentrated hydrochloric acid to clean a platinum / nichrome wire.Then put the wire to dip some solid sample.

步骤： 用浓氢氯酸去清洗一铂线/镍铬线，再用铂条去沾起一些固体样本。

Mercury was released from the gold trap by heating the glass tube to 550 OC for 20 s with a 22 gauge nichrome wire coil (4 cm L, 38 turns) with a variable voltage controller set at 25 V.

将可变电压22号镍铬电热丝调整至25伏，加热黄金装置到550度并维持20秒使汞释放出来。

Quartz tube was placed between the GC column outlet and the detector and heated to 700℃ with a 22 gauge nichrome wire coil (8 cm L, 50 turns)(Variable Voltage Controller set at 50 V) to decompose the organic mercury species to HgO.

加热镍铬电热丝至350度9秒钟，使不同的有机汞从Carbotraps中释放出来。气相色谱分析，95℃下用充满60/80网孔15% OV-3红色硅藻土色谱载体WAW-DMCS约束于修改的GC炉。

Also can be used in aluminum, magnesium, steel, nickel, copper bare surface , Also can be used in chromic acid silver, nickel and other substances for spraying materials On the processing pieces.

也可以用在铝，镁，钢，镍，铜的裸表面上，也可以用在铬酸银，镍和别的物质作喷涂材料的加工件上。

It is shown that the stainless steel without Nickel or Chromium has good mechanical properties and good resistance to corrosion and oxidation, and properties equivalent to 304 and 305 stainless steels.

结果表明：本文所设计的无镍铬不锈钢具有优异的力学性能，良好的高温抗氧化性和耐海水腐蚀性，且达到ZG304、ZG304不锈钢的性能指标。
