Temperature Ranges

Present fiber optic connections need to align two or more optical fibers to accuracies of microns (multimode fiber) and tenths of a micron (single more fiber). For connections in rugged applications, consisting of wide temperature ranges, substantial vibration, or in the presence of contaminants, the alignment of normal physical contact connections becomes even more difficult. New expanded beam connectors make fiber optic connections more durable, and help stabilize the transmission of high speed optical signals between systems, boxes, boards, and devices in these harsh environments.

Loess Landslides

Over-irrigation can induce serious landslides on the slopes of loess terraces. Typical examples are the series of landslides that happened in the last few decades on the Forth Terraces of the Yellow River at Heifangtai, Yongjing County, Gansu Province. Agricultural irrigations began on the Heifangtai terraces in 1960s. Due to the specific geological and geomorphological conditions of the thick loess terraces, a great amount of irrigation water infiltrated into the loess causing serious landslide problems. The landslides at the Heifangtai can be classified into two different types based on their composition: loess landslides and loess-bedrock landslides, characterized by high-speed, long-distance sliding and low-speed, short-distance sliding respectively. Landslides caused by over-irrigation have a special phenomenon of hysteresis development following long-term of irrigation, occurring in groups and with high frequency. Most of the landslides happen in rainy seasons and freeze-thaw periods.
