解釋
壓力衰減-
Standard test methods for pressure decay leak test for nonporous flexible packages with and without restraining plates
有或無約束板的無孔撓性包裝件壓力下降泄漏試驗的標準試驗方法 -
Symptoms of calcium deficiency include muscle cramps, tremors, or spasms, insomnia, nervousness, joint pain, osteoarthritis, tooth decay and high blood pressure. severe deficiency results in osteoporosis or porous bones
人體從35歲左右開始，每天就會丟失30 - 50毫克的鈣質，到了50歲，骨頭的總重量減輕至0 . 7公斤左右。 -
So does the finding that an area of missing scalp was caused by pressure, not by a blow or decay
在這方面，還有其他證據，例如奧茲的頭皮有一部份不見了，專家發現是壓力造成的，而不是打擊或腐爛的結果。 -
The sense of this work is to gain a further understanding of helium in the two metals. on the diffusion of helium - 3 in two spherical shell samples made of 21 - 6 - 9 type of stainless steel, during the storage of tritium at the pressure of 6. 13mpa for about 4 and 6 years at room temperature and later exposed to air for another 3 and 1 year. first, a calculation based on the analytical and numerical method to the diffusion and decay theories was developed to evaluate the concentration distribution of helium - 3 by tritium diffusion and decay in the samples
在不銹鋼氚衰變~ 3he的擴散行為研究中，建立了氚和~ 3he濃度分佈的解析解和數值計算方法，以評估充氚不銹鋼球形容器壁中氚衰變~ 3he的宏觀濃度分佈，同時還用數值計算方法以求解氚和~ 3he的多步擴散行為；對樣品表面逐層蝕刻、同時收集釋放的~ 3he進行分析，分別實測了經室溫條件下在6 . 13mpa高壓氚中貯存4年和6年、空氣中存放3年和1年的兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he濃度分佈；結果表明：由於he在金屬中的不可容性， he原子偏聚于不銹鋼表面以及內部的局部區域，在整體趨勢上， ~ 3he分佈與計算結果相一致，根據理論計算，兩種21 - 6 - 9不銹鋼球殼樣品內壁中~ 3he到達的深度分別為350 m及500 m 。 -
The evolution of shock wave can separate into three stages as ( 1 ) the forming stage “ pressure increases ”, ( 2 ) the stage of “ maximum pressure ”, ( 3 ) the decay stage “ pressure decreases ”
當激光強度保持恆定時，施於靶面的燒蝕壓力亦保持不變，因而此時靶內的激波陣面壓力會維持一個平穩階段。
