以羊毛脂石蜡油（质量比3：2）为溶剂配制尿酸酶抑制剂，采用皮下注射的方法造模，所复制的大鼠代谢性高尿酸血症模型具有血尿酸值高、维持时间长的特点。

The definition of generator angle is proposed in this paper. A new method to deduce generator angle by using rotor rotation signal is illustrated, which compares the phase difference between GPS timing pulse and RRS. Using only mechanical signal, the technique unfreezes limitation of zero-cross of generator terminal voltage during transient process. Automatic correction of initial generator angle is also proposed .

本文介绍了同步发电机绝对转子角的定义，提出了一种测量绝对转子角，进而获得高精度的相对转子角的方法；此方法不使用机端电压过零整形脉冲，而是将机组键相脉冲与GPS 定时脉冲比相，并能够自动整定初始位置角，因此，测量结果不受发电机运行状态的影响，能够在各种运行方式和扰动情况下获取高精度的绝对转子角。

In addition to their higher thermal stability, neoalkoxy titanates offer somewhat enhanced final properties compared to monoalkoxy counterparts; according to Monte, the properties obtained with monoalkoxy coupling agents are about 92% of those with neoalkoxy variants.

除了具有高的热稳定性，比单烷氧基钛酸酯提供更高的最终性能。按照 Monte 的说法，单烷氧基钛酸酯获得的性能大约是新烷氧基钛酸酯的92%。

A telecine machellone copies the film digitally from the reels. Sound and picture should be very good, but due to the equipment involved and cost telecines are fairly uncommon. Generally the film will be incorrect aspect ratio, although 4:3 telecines have existed. A great example is the JURASSIC PARK 3 TC done last year. TC should not be confused with TimeCode , whelloch is a visible counter on screen throughout the film.

TELECINE 使用电视机影戏机从胶片直接数字拷贝，其图像伴唱音质量应该很好但由于使用的设备和费用很高，TC很少见通例会使用不错的高宽比，但有时也有4：3的 TC上年的侏罗系公园III是一个很好的例子不应将TC和TimeCode混合，时间码是一个在屏幕上可见的计数器

In fact, we had obtained polythiophene films with high quality in BF3 ethyl ether, a kind of solvated Lewis acid. The electric conductivity of the polythiophene film is a bout 100 Scm-1. and the tensile strength is as high as 140 MPa, which is forty percent higher than that of aluminum.
