There is no fixed recipe in approaching metering in all kinds of situations. It's a mix-n-match of different techniques - all used to make sure I get optimum exposure for my images.
当然因为情况多种多样，不可能有一种固定方法能适用于所有的情况。一般需要多种技术进行组合以取得最好的曝光。
The number of GM decreased as the slope exposure turned from N to S, as slope increased, and as slope shape turned from convex to concave.
GM平均胸径还与坡位正相关； GM数量沿N→S的坡向梯度减少，而随坡度增大及坡形由凹转凸而增加；
It is postulated that N nitrosamides, such as NMU could be formed endogenously in the stomachs of local residents who consume fish sauce often and have a higher exposure to nitrite in their stomachs.
因此推测胃内亚硝酸盐水平较高且经常食用鱼露者，胃内极可能有NMU 等亚硝酰胺的内源性合成。
