When the density step wedge has been properly exposed, the film is then processed.

He also discovered how to take pictures using a short exposure.

他又发现了短暂曝光照相法.

An exposure of one-hundredth of a second will be enough.

曝光百分之一秒就够了.

It is of significance to prepare TiAl-based alloys by cold crucible electromagnetic confinement and directional solidification technique because of its unique features without contamination and continuity during process.

冷坩埚电磁约束成形与定向凝固技术对于探索高质量钛铝基合金的制备成形具有重要意义。

However, local buckling is more likely to occur for thin-walled tubes, and thus decreases the lateral confinement on the concrete core.

但薄壁钢管在荷载较大时易发生局部屈曲，且降低对混凝土的约束。

For the same lateral confinement, high strength concrete columns develop lower strength enhancement than normal strength concrete columns.

在相同的侧向约束下，高强混凝土柱的核心强度提高幅度低于普通混凝土柱。

The expansive agent can enhance the impermeability and the cracking-resistance of concrete through the working of the compensation shrinkage of concrete produced by confined expansion when it is added to concrete.

膨胀剂掺入到混凝土中，通过产生一定的限制膨胀，补偿混凝土的收缩，有利于提高混凝土的抗渗防裂。

It has been proved by the investigation that the filling effect of the confined expansion makes the reduction of holes in concrete as well as the increase of strength and elastic modulus of concrete.

实验证明：由于约束膨胀的填充作用，大幅度降低空隙率及孔径，定将有效地提高混凝土的弹性模量及强度。

The reinforcement ratio of a construction must be designed to create adequate confined expansion in the shrinkage_compensation concrete.
