注意，在拖放本地文件时，值不变。

Note that, in the case of dragging and dropping local files, the values are the same.

因而，轮询收集器通常使用粘附跟踪程序类型：apm系统在生成报告时将假定所有轮询事件之间的值不变。

Accordingly, polling collectors typically use sticky tracer types: the APM system reports the value as unchanged in between all polling events. Figure 4 illustrates this pattern.

也可以将其移出循环，因为这个值是不变的。

You should also move it outside of the loop since its value is invariant. So, in the.data section, add.

So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.

如果我们保持ｎ不变，我们看到随着ｌ值的,增大尺寸变小。

And when I do this test, what I want to do, is say I'm going to pick the middle spot, and depending on the test, if I know it's in the upper half, I'm going to set my start at the mid point and the end stays the same, if it's in the front half I'm going to keep the front the same and I'm going to change the endpoint.

如果我知道目标数可能，再比中值点大的区间里，我可能就会把开始点设为中值点,而尾点不变，如果在小的那个区间里,就保持开始点不变而把尾点设为中值点，你们可以看到这儿的代码,就是这么做的,对不对？它是怎么做的？

I'm using the fact that when you take a cosine and change the angle inside the cosine, it doesn't care. whereas, if you go to the sine and change the angle inside the sine, it becomes minus sine.

我用了一个结论,当你使用余弦函数时,改变角度的正负,函数值不变,而对于正弦函数,改变角度的符号,则函数值也会变号
