Construction Materials Testing and Special Inspections (CMT/SI) are vital to a project’s construction and overall lifetime success. TD2 has an in-house CMT/SI lab which provides quantifiable results on the durability, strength, and characteristics of materials including masonry, soils, cast-in-place concrete, and asphalt so they perform as ...

Working alongside our CMT and Geotechnical staff, CVET’s SI staff offers complete start-to-finish construction process services. Our turnkey approach minimizes communication time, travel time, and overall costs associated with projects.

Construction Materials Testing and Special Inspections (CMT/SI) are the tests, inspections, quality assurance programs, and engineering that ensure the safety and quality of materials used in vertical construction. Every piece of a building is inspected, measured, and tested for its adherence to local, state and national building codes of safety.

Our Construction Materials Testing & Special Inspections (CMT/SI) team ensures project safety through high-quality materials testing.

提单补料（Bill Of Lading Supplement，也叫Shipping Instructions，简称SI），就是货方向船公司提供这批货物的详细资料——也就是提单上要求填写的各项内容。 提供了SI，意味着作为发货方，已经确认了提单信息。 补料是确认提单样本的最后一步。

CMT理论主要基于 微扰理论，其认为器件结构中的介电常数变化为微扰过程，会与无微扰结构中的 简并模 发生耦合，其介电常数可写作: 无微扰情况下的简并模由于其不随传播Z方向变化，可以将 (x,y)的模场分布与沿Z反向的传播常数分离，而在该波导中传播的总的光场分布可以看作是所有简并模的线性叠加: 简正模是正交的，且做归一化处理，可以用如下表示: TE模: TM模 ·: 微扰理论通过" 常数变易法 ”求解，在介电常数微扰的情况，此时的光场分布为: 可见，此时原先的常 …

The CMT / SI Quality Assurance Trainer is responsible for developing NOVA's field employees in the Carolinas region and improving their abilities related to field and laboratory testing procedures (ASTM, ACI, etc.); reading plans, specifications, submittals, correct/accurate/complete/timely reporting of field observations and tests in Metafield ...

The Com-Pressor™ SI Belt is a superior pelvic compression belt that helps promote pelvic and core stability during retraining of impaired lumbo-pelvic core muscles that may develop from pregnancy, surgery, sprains and more.

本研究的创新点在于使用TiC纳米颗粒来改善CMT-WAAM技术在铝硅合金沉积中的微观结构和机械性能。 通过层层堆叠TiC纳米颗粒，可以促进细晶粒的形成，提高试样硬度和抗拉强度，同时显著提高试样的断裂伸长率。

摘要 针对铝合金激光-CMT (cold metal transfer)复合焊焊缝性能不足的难点,采用两种不同Si含量焊丝 (Al-Si5和Al-Si10焊丝)对铝合金进行激光-CMT复合焊,研究焊丝中Si含量对焊接接头焊缝组织、晶粒尺寸及力学性能的影响规律。
