The  force of gravity perpendicular equals mass times gravitational field strength times the cosine of  the incline angle.

垂直重力等于质量乘以重力场强度乘以倾斜角的余弦。

The force of gravity parallel equals mass times gravitational field strength  times the sine of the incline angle.

平行重力等于质量乘以重力场强度乘以倾斜角的正弦值。

Its magnitude equals the mass  of the fluid displaced by the object times the gravitational field strength hold up, mass times  acceleration due to gravity?

它的大小等于物体排出的流体质量乘以引力场强度，质量乘以重力加速度？

I will add that the composition of the object  which is submerged in the fluid does not affect the buoyant force, only mass of the fluid  displaced by the object and the gravitational field strength determine the buoyant force.

我要补充一点， 浸没在流体中的物体的成分不会影响浮力，只有物体位移的流体质量和重力场强度决定了浮力。
