Wagner Fineness

แปลว่า(Concrete Engineering) The fineness of materials such as portland cement expressed as total surface area in centimeters per gram as determined by the Wagner turbidimeter apparatus and procedure.

Moment of inertia (I):

แปลว่า(english) Moment of inertia has two distinct but related meanings: 1) it is a property of a an object relating to the magnitude of the moment required to rotate the object and overcome its inertia. 2) A property of a two dimensional cross section shape with respect to an axis, usually an axis through the centroid of the shape.

Centroid:

แปลว่า(english) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.

Degree of Freedom:

แปลว่า(english) A displacement quantity which defines the shape and location of an object. In the two dimensional plane, a rigid object has three degrees of freedom: two translations and one rotation. In three dimensional space, a rigid object has six degrees of freedom (three translations and three rotations).

Pin support:

แปลว่า(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

AB Srews

แปลว่า(english) Sheet metal screws with pointed ends similar to type-A screws and thread dimensions similar to type-B. Type AB screws are seldom used in stainless.

Primary treatment

แปลว่า(Environmental Engineering) Treatment which includes all operation prior to and including primary treatment, e.g., bar screening, grit removal, comminution, and primary sedimentation.

dim

แปลว่าหรี่ (ไฟ), พร่า, มัว

sediment control

แปลว่าการควบคุมตะกอน : การลดปริมาณตะกอนในลำน้ำเพื่อป้องกันหรือลดอัตราการตกตะกอนในระบบส่งน้ำ แหล่งเก็บกักน้ำ และแหล่งน้ำอื่น ๆ

three-dimensions

แปลว่า3 มิติ มีทั้ง กว้าง ยาว หน้า

Secondary treatment

แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

pediment

แปลว่าส่วนยอดหลังตู้หรือยอดจั่วหลังคาที่ทำเป็นรูปสามเหลี่ยม หรือเป็นรูปสามเหลี่ยมที่ยอดไม่บรรจบกัน ส่วนนี้เราเรียกว่ากระจัง
