![]() | U238_fission_Chain Reaction(核分裂) 核分裂連鎖反応の概念図。1. あるウラン235原子核が1個の中性子を吸収し、2個の新たな原子核(核分裂片)に分裂する。同時に3個の新たな中性子といくらかの結合エネルギーを放出する。2. 放出された中性子のうちの1個がウラン238原子核に吸収される。この場合は反応は続かない。別の1個の中性子は他の原子核と衝突せずに失われる。この場合も反応は続かない。しかし残りの1個の中性子は別のウラン235原子核に衝突する。この原子核は核分裂を起こして2個の中性子と結合エネルギーを放出する。3. ここで放出された中性子は2個とも別のウラン235原子核に衝突し、それぞれ核分裂を起こして1~3個の中性子を放出する。こうして反応が持続する。 連鎖反応(れんさはんのう、nuclear chain reaction)とは、平均して1回以上の核分裂反応が別の核分裂反応を引き起こし、単位時間当たりの反応回数が一定もしくは指数関数的に増加する状態である。 十分に多量(臨界量以上)の核分裂性物質の中で、制御されない状態の下で連鎖反応が起きると、エネルギーが爆発的に放出される。これが核兵器の動作原理になっている。連鎖反応は十分に制御された状態でエネルギー源としても用いられる(原子炉など)。 2010年09月04日再生回数 7258 |

![]() | Anne Baxter, Steve Cochran, Lyle Bettger and George Nader in Carnival Story (1954 Movie) DVD: www.amazon.com thefilmarchive.org Carnival Story is a 1954 film directed by Kurt Neumann, starring Anne Baxter and Steve Cochran. The film was shot in 3-D, but was only released to theaters in 2D ("flat"). Neumann simultaneously directed a German language version Rummelplatz der Liebe (1954) with Bernhard Wicki, Eva Bartok, and Curd Jürgens. Cast * Anne Baxter as Willie * Steve Cochran as Joe Hammond * Lyle Bettger as Frank Colloni * George Nader as Bill Brines * Jay C.

Steve Cochran (May 25, 1917 - June 15, 1965) was an American film, television, and stage actor, the son of a California lumberman. He graduated from the University of Wyoming in 1939. After a stint working as a cowpuncher, Cochran developed his acting skills in local theatre and gradually progressed onto Broadway, film, and television. Lyle S. Bettger (February 13, 1915 -- September 24, 2003) was a character actor known most for his Hollywood roles from the 1950s, typically portraying villains. He is perhaps most recognisable as the wrathfully jealous elephant handler Klaus from the Oscar winning film The Greatest Show on Earth (1952). George Nader (October 19, 1921 -- February 4, 2002) was an American film and television actor of Lebanese descent. He ... 2011年05月15日再生回数 422692 |
![]() | Raquel Welch, Barbara McNair, Miss World and Phil Crosby in the Bob Hope Christmas Special (1967) DVD: www.amazon.com thefilmarchive.org Raquel Welch (born September 5, 1940) is an American actress, author and sex symbol. In 1959, Welch played the title role in The Ramona Pageant, a yearly outdoor play at Hemet, California, which is based on the novel Ramona by Helen Hunt Jackson and Bob Biloe. She became a weather forecaster at KFMB, a local San Diego television station. Because of her heavy schedule, she decided to leave her studies at San Diego State University (then known as San Diego State College). Her first marriage broke up and she moved with her two children, Damon and Latanne, to Dallas, Texas, where she modeled for Neiman Marcus and worked as a cocktail hostess, intending to move on to New York City from there. Instead, Welch moved back to California, found a place in Los Angeles and started making the rounds of the movie studios. She was cast in bit parts in two films and in the television shows Bewitched, McHale's Navy, and The Virginian, as well as on the weekly variety series The Hollywood Palace as a billboard girl and presenter of acts. Welch's first featured role came in the beach film A Swingin' Summer, which led to a contract with 20th Century Fox. She was subsequently cast in a leading role in the sci-fi hit Fantastic Voyage (1966), which made her a star. She was the last star created under the studio system. On loan out to Hammer Studios in Britain, Welch starred in the remake of One Million Years BC striking an iconic pose in a prehistoric ... 2011年05月14日再生回数 173806 |
