$_SERVER['QUERY_STRING'] 这个应该是一个定义的服务器变量
src="modules.php{echo:'.$_SERVER['QUERY_STRING'];/}" 大致意思就是读取变量,输出成 modules.php?param=12123

(1)p1是定滑轮,一根绳上的各质点速度大小相同,p2是动滑轮,故有v2:v1=1:2恒成立.又初速度为零,故a1:a2=2:1
(2)(3)对m2受力分析有:t1=2t2=2m2a2
对m1受力分析有:m1g-t1=m1a1
故t1=(m1*m2*g)/(m1+m2)
t2=(m1*m2*g)/2(m1+m2)
a1==(m1*g)/(m1+m2)
a2==(m1*g)/2(m1+m2)
so easy

第一个int类型的group ID参数,代表的是组概念,你可以将几个菜单项归为一组,以便更好的以组的方式管理你的菜单按钮.
第二个int类型的item ID参数,代表的是项目编号.这个参数非常重要,一个item ID对应一个menu中的选项.在后面使用菜单的时候,就靠这个item ID来判断你使用的是哪个选项.
第三个int类型的order ID参数,代表的是菜单项的显示顺序.默认是0,表示菜单的显示顺序就是按照add的显示顺序来显示.
第四个String类型的title参数,表示选项中显示的文字.

一道英文物理题哦A ball of mass m is attached to a string of length L
一道英文物理题哦
A ball of mass m is attached to a string of length L .
It is swung in a vertical circle with enough speed to keep the
string taut throughout the motion. Assume the ball travels
freely in the circle with negligible loss of mechanical energy.
Determine if the following six statements are true or false;
e.g., enter 输入TTFFFF.
i) mvt
2 /L = Tt−mg , where vt and Tt are the speed of the
ball and the tension of the string at the top of the circle.
ii) The speed of the ball at the bottom of the circle is greater
than the speed at the top of the circle.
iii) The tension in the string is less at the top of the circle than
at the bottom of the circle.
iv) The difference between the tensions at the top and at the
bottom of the circle depends on the average speed of the
ball.
v) The acceleration of the ball at the top of the circle is di-
rected ‘down’.
vi) The tension in the string at the top of the circle is always
greater than the weight of the ball.
Assume that m = 0.40 kg and L = 1.65m. What
is the difference in tension, Tb−Tt , between when the ball is
at the bottom and when it is at the top?

选 B。 list可以存放任意类型,但不是有序的,否则也不会有sort方法了。len实际上通过__len__来实现的,对string 和list都支持。string、list都可变,python不可变的是tuple

astrigent的意思是收缩毛孔的
这里作名词,意思是那些用来收缩毛孔的东西,护肤品里来说,一般是指收敛化妆水,那种化妆水一般含有酒精或是金缕梅提取物用来帮助收缩毛孔,所以会伴随着产生干燥皮肤的现象,也就是drying,使干燥
这句话的意思是,你这个产品是一个可以用来代替那些使皮肤干燥的收敛物的产品
简单来说,就是这个产品可以收敛毛孔但是不会干燥皮肤
