结果表明，与常规高温匀染剂相比，高温匀染剂JL能使初始上染速率较高的染料上染速率降低，使初始上染速率较低的染料上染速率提高，改善了染料的配伍性，提高了染料的移染性和高温分散性，且对染品的染色牢度影响不大。

Network economy could reduce costs of exchange and achieve economies of scope and economies of integration. The advancements of network economy urge it to be the mainstream over obstacles. It shifts situations between supplier and demander, changes the characters of demanding and factors of purchasing. Those engender new type of demand. Estate agencies, which integrate on-line and off-line services, will achieve dominancy in the market. In general, estate agencies have to shift from the necessary intermedia to assistant roles. Network economy supplies a gap of information deficiency in estate market and levels down the amplitude of estate economy cycle. Informatization of industry management enhances market efficiency, at the same time decreases systemic risks.

Diopside crystals in fluosilicate glass-ceramics tend to lower thermal expansion coefficient, while richterite crystals in fluosilicate glass-ceramics tend to increase thermal expansion coefficient.The lowest thermal edpansion coefficient of K2O-MgO-SiO2-CaF2 fluosilicate glass-ceramics is 78.4×10-7(20-300℃), while the highest thermal expansion coefficient of this glass-ceramics is 85.6×

透辉石结晶相的含量增加使微晶玻璃的热膨胀系数降低，与此相反碱镁闪石结晶相的含量增加却使微晶玻璃的膨胀系数增加。K2O－MgO－SiO2－CaF2系统氟硅酸盐微晶玻璃的最小热膨胀系数为：78.4×10－7（20～300℃）；最大热膨胀系数为：85.6×10-7（20～300℃）。

The assembly method of the invention has the main principles that a semiconductor laser, an optical coupled apparatus and a fiber head are orderly arranged, and the optical axes of the semiconductor laser, the optical coupled apparatus and the fiber head are arranged in a same straight line; the focal plane of an output beam which is focused on the fiber head is changed through utilizing and adjusting an adjusting device which can cause a beam to deviate; the sensitivity of the assembly adjustment of the adjusting device in the course of fixing is reduced.

本发明的方法的主要原理是将半导体激光器、光学耦合器件、光纤头依次排列，并使它们光轴在同一直线上，然后通过利用一使光束发生偏移的调节器件，通过调节该调节改变聚焦于光纤头的输出光束的焦平面，降低调节器件装配调节的固定时的敏感性。

Normal working hours, B2-B1 between the need to add a positive voltage, E-B1 between the PN junction forward biased if the Canadian single-junction transistors that turn, after turn-on, E-B1 between the resistance will soon be reduced, to B2-B1 between the current rapid increase in current increase, so that the resistance between the E-B1 further reduced, so the formation of a strong positive feedback.

正常工作时，B2—B1间需加正电压，E—B1间的 PN结若加正向偏置，单结晶体管即导通，导通后，E—B1间的电阻会很快降低，使B2—B1间的电流迅速增加，电流的增加，又使E—B1间的电阻更进一步的减小，如此形成了强烈的正反馈。

Based on the first law of thermodynamics and the law of hydrokinetics, the mathematic model of the pressure characteristic was established for the 252 kV self-extinguishing SF6 circuit breaker, and the pressure characteristic curve of the arc-extinguishing chamber can be obtained through computation.
