I continued this unequal contest for an exhausting half hour, before realizing that I could not win my way to the bright area ahead of me.
半小时后,精疲力尽的我停止了这场不公平的抗争,意识到自己根本无法到达那片晴朗的天地。
The bright area of reflex is enclosed by the reflection points of two ends of linear lamp-house at the edge of orifice of lamp and points of intersection with testing screen.
反射光的亮区是由线光源两端点在灯口边缘上的点反射且与测试屏交点所围成的。
Therefore, along with the increasing of the filament length, the corresponding bight zone becomes larger and larger, and a continuously peach-form bright area can be formed on the test screen.
利用此结论,可以知道,随着灯丝的变长,亮带不断外推,从而在测试屏幕上形成连续的亮区,这比较清楚地解释了测试屏幕上桃形亮区的形成机理。
