  1. At linear stage, the theoretical growth rate for the rt instability in cylindrical and spherical geometries was enhanced ( or reduced ) due to the decrease ( or increase ) in the perturbation wavelength during an implosion ( or explosion ). even in the absence of an acceleration the perturbation could grow in the convergent geometries. the amplitude growth rate was proportional to the cube of the convergent ratio in spherical geometry and to the square of the convergent ratio in cylindrical geometry

    在線性階段，已有的研究表明：一方面，在內爆（或外爆）過程中擾動波長變短（或變長） ，使得不穩定性的增長率變大（或變小） ；另一方面，即使不存在界面加速度，界面運動仍然可能導致擾動幅度的增加，柱幾何中擾動幅度的變化速率正比于界面收縮比的平方，球幾何中擾動幅度的變化速率正比于界面收縮比的三次方，並且擾動幅度的變化方式（增加或減少）只與初始時刻擾動幅度的增長速率（正或負）有關，而與界面的運動方向（向內或向外）無關。
  2. This paper uses an optically modulated scatterer system to measure microwave field with minimal disturbance. this method is especially adapt to measure magnitude and phase of microwave field close to conductor and microwave field with complex path between source and field. so it can be used to measure radiation antenna ’ s near - field and microwave into slots

    光調制散射器的測量方法最大限度地減少了測量裝置對被測場的擾動，特別適合於測量導體附近和具有復雜路徑場的幅值和相位分佈，可以用於對輻射天線近場的測試以及孔縫耦合中場的測量，可為天線的設計，微波孔縫耦合效應的研究提供較精確的實驗數據。
  3. It is found from the experiment that under the conditions of peak magnetic field of 0. 57t, beam pulse fwhm ( full width of half maximum ) of 44ns, a microwave radiation pulse with fwhm 25ns and whole width of 35ns is produced, when the intensity of the guiding magnetic field rises, the peak microwave power changes little but the width of the pulse reduces. the a - k gap also has obvious influence on the microwave radiation, the stable and higher microwave output is obtained under suitable gap

    實驗中還發現，在峰值磁場0 . 57t和束流半高寬44ns情況下，得到了25ns半高寬和35ns底寬的微波脈沖信號，隨著導引磁場增加，微波信號幅值基本不變，但國防科學技術大學研究生院學位論文是微波脈沖寬度會逐步減少;實驗中還發現磁場線圈位置有一定的軸向調節范圍，說明在磁場軸向分佈的一定變化范圍內，器件都可以正常工作，這對以後的永磁場系統導引的微波實驗有利。
  4. Esserman said most cities have fewer police officers now than in 2001, with big reductions in new york, boston, massachusetts, and detroit, michigan, “ because of the loss of federal money

    埃瑟曼說，大部分城市現在的警員都比2001年時少，紐約、波士頓、馬薩諸塞、底特律河密切根更是大幅度減員， 「因為缺乏聯邦資金。 」
  5. These stocks will be used to reduce or eliminate the wide fluctuations in commodity prices.

    這些儲存將用來減少或消除商品價格的大幅度波動。
  6. The impacts of soil and water conservation on river flows have been analyzes by comparison of the runoff amount of prophase and anaphase period. the results indicated that the precipitation producing waters and annuals fluctuate of runoff amount in each catchment have been decreased mainly by soil and water conservation

    根據臨界年份把河川徑流量分為前期和後期兩個時期，比較分析了水土保持對河川徑流量年際變化的影響，指出：水土流失綜合治理使流域降雨產流量減少，徑流量年際波動幅度降低。
