200c

They can be used at 200C in a long term and are potential heat-resistant plastics .

说明此种模塑料能在200℃以下长期使用，是一种有发展前途的耐热塑料。

The optimum magnetic property can be obtained with heating from 200C to 500C gradually and holding time for 10 min.

在预热温度200℃逐渐加热到500℃并保温10min时，薄膜磁性能最佳。

However , the corrosion rate of carbon steel increases sharply when the temperature is higher than 200C except that of in 55 % LiBr solution .

超过200℃后，除55%LiBr溶液外，碳钢溶解速度都急剧增大。

The H2 sensitivity of these two film samples raised with temperature , and this tendency pricked up when the temperature was over 200C .

这两种薄膜样品对H2的灵敏度随温度上升而增大，这种趋势在200℃以上时进一步加剧。

西芹叶少量，剁碎•将烤箱的热风加热到220C，煤气开到7档200C。

Drain the pineapple and reserve the juice for the later use . Preheat the oven to 200C / 390F .

把罐头菠萝沥干，菠萝汁备用。预热烤箱到200C/390F。

Preheat oven to 200C / 400F . Sift flour then add baking powder , salt , sugar , and coconut and mix through .

烤箱预热到200C/400F。面粉过筛后加入烤粉，食盐，砂糖，和椰丝混合均匀。

In this paper , the polymerization rate and average molecular weight of thermal-initiated polymerization of styrene in the range of 120 ~ 200C were studied . The polymerization rate was found to be proportional to the square of styrene concentration , thus a second-order initiation is inferred .

在120～200℃内，对热引发苯乙烯本体聚合的速率及平均分子量进行了研究，得到聚合速率与单体浓度二次幂有关，据此可以推论引发速率也和单体二次幂有关。
