1. While this showed astronomers that Venus was surrounded by a thick layer of gases refracting sunlight around it, both effects made it impossible to obtain accurate timings. 尽管这向天文学家证明了金星被一层厚厚的气体所包围，这层气体使太阳光在金星周围发生折射，但这两种效应都使精确的时间控制成为不可能。
2. Now some details of the costs and timings. 接下来是关于成本和时机的一些细节。
3. When Venus begins to cross the Sun's disc, it looks smeared not circular—which makes it difficult to establish timings. 当金星开始穿过太阳的圆盘时，它看起来有斑点，不是圆形的——这使得确定时间变得困难。
4. Throughput timings of connections. 连接的吞吐量时间开销。
5. Modifications to detect release timings only. 仅检测键释放计时的修改。
