LTV的音标

the flame retarding silicone elastomers which meet the requirements of ul-94 and emit no fumes or toxic vapors when burning can be made from the modified rtv, ltv, or htv silicone rubbers by adding some flame retarding agents and other chemical additives.

以改性的RTV、LTV、HTV硅橡胶为基础胶，加入适量的阻燃剂和其他助剂，制备成符合UL94标准和燃烧时不产生浓烟及有毒气体的阻燃型硅橡胶。

new silicone flame retardant potting compound was prepared by blending of ltv silicone rubber as base gum with diluent, crystalline quartz filler, chain extension agent, crosslinking agent, inhibitor, carbon black and platinum catalyst.

以中温硫化硅橡胶（以下简称LTV硅橡胶）为基胶，混入稀释剂、石英粉、链增长剂、交联剂、阻聚剂、炭黑及铂催化剂等组分，制得新型有机硅阻燃灌封料。

In detail, the chained system is divided into a scalar subsystem and a ( n-1)-dimensional LTV subsystem, then the controllability of the LTV subsystem which has a time-varying function system matrix is proved.

首先将n维链式系统分解成一个标量子系统和一个n？1维线性时变子系统，证明了一定条件下该时变子系统的能控性。
