High strength: Aluminum-magnesium-silicon alloy wire possesses high strength, its min value of tensile strength is 170% of the value of general hard and round aluminum wire(H8), is a fine armored material;②Low loss:as a non-magnetism material, no eddy current loss will happened on aluminum-magnesium-silicon alloy wire; when under 20℃, itsunit resistance corresponding to 52.3~53.0%IACS (international annealed copper wire standard), so that, the heat loss caused by induced current is very low;③Light weight: the density of aluminum-magnesium-silicon is only 2.7g/cm3 it largely reduced the total weight of armored cable.

該電纜突出的優(yōu)點(diǎn)是：①高強(qiáng)度：鋁-鎂-硅合金絲具有較高的強(qiáng)度，其抗拉強(qiáng)度的最小值都是普通硬圓鋁線（H8）抗拉強(qiáng)度的170%黃色A片三級三級三級在线，是一種較好的鎧裝材料女人高潮A级毛片；②損耗小：鋁-鎂-硅合金絲為非磁性材料日韩插插碰碰，不存在渦流損耗六区七区黄片；其在20℃時(shí)的電阻率相52.5~53.0%IACS，因此由感應(yīng)電流產(chǎn)生的熱損耗很性谙吖劭疵夥训某赡晖尽久久久久久无码精品；③重量輕：鋁-鎂-硅合金絲的密度僅為2.7g/cm3，明顯降低了鎧裝電纜的整體重量很黄很色视频。

Dropping time of ammonia solution and dispersing time of TMAOH were found to have influence on magnetism and dispersion of Fe3O4 nanoparticles.

研究了氨水的滴定時(shí)間和氫氧化四甲基銨分散時(shí)間對(duì)Fe3O4微粒磁性和分散性的影響久操中文字幕视频在线观看，并據(jù)此選擇了最優(yōu)化條件獲得了分散性和磁性相對(duì)較好的Fe3O4磁流體。

Curie point: The temperature at which a material loses its ability to retain magnetism, that is, changes from ferromagnetic to paramagnetic behavior.

居里點(diǎn)：使物質(zhì)失去維持磁性能力時(shí)的溫度91jiuse在线观看，也就是26uuu在线，達(dá)到該溫度時(shí)物質(zhì)從鐵磁性狀態(tài)變成順磁性狀態(tài)。

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates and are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion.

在此文內(nèi)222aaa男人的天堂免费网址，作者利用復(fù)變來曼幾何以宇宙間兩點(diǎn)之距離為一實(shí)數(shù)及一虛數(shù)部分相構(gòu)而成v在线观看欧美精品，於此并用假說：一可稱為吸力及電磁定律，一為物體行動(dòng)定律特级无码毛免费视频，解釋吸力及電磁力之各種現(xiàn)象日韩无码导航视频。
