英文
minimum detectability-
Based on the curve, the adulterated peanut oil can be detected fast, the error amount of which is at least 5 %
發現油中脂肪酸組成及其特徵組分的變化成線性規律，由此做出工作曲線，可快速定性、定量摻偽油，且摻偽量的最低檢出限可達到5 % 。Noninstrumental method : the lod is generally determined by the analysis of samples with known concentrations of analyte and by establishing the minimum level at which the analyte can be reliably detected
非儀器分析目視法：通過用已知濃度的樣品分析來確定可檢出的最低水平作為檢測限。Through the theory of light radiation and intensity, we can use the fewest leds to satisfy the luminous intensity demand. through image segmentation theory, we can accurately pick module up from the test stripe when it is put in wrong directions. through image processing theory, we can acquire correct information and avoid the bad effects from the asymmetric chemistry reaction and instability of the devices
用光的輻射和強度理論，我們計算出了獲得足夠圖像強度所需的最少光源;用圖像分割理論，我們在試紙條傾斜放置或有垂直方向上的偏移時，準確地提取出了各模塊的數據;用平滑濾波和均值濾波理論，我們濾除了由於反應不均勻及硬體設備不穩定帶來的噪聲;用交遇區設計線性分類器的方法，我們降低了有限樣本設計線性分類器帶來的誤差，提高了檢驗準確度。The within - run coefficient variations were all less than 10 %
採用相同的抗原和抗體， elisa的最低檢出限為0The optode shows a satisfactory linear response for the dissolved oxygen in water ( r = 0. 9992, n = 6 ) the relative standard deviations were 1. 7 % 5. 0 %, the detection limit was 0. 03 11 g / ml ( sfn = 3 ). the exposure time and recovery time of the optode membrane are 30s and 90s respectively. the reversibility of the fluorescence signal was evaluated by alternate measurements in oxygen saturated water and nitrogen - purged water
7 5刀之間，最低檢出限為0刀3pg il ；考察了標準海水中主要離子濃度放大1倍后的樣品溶液、鹽度在0 49范圍內的人工海水，以及ph在l 13范圍內的緩沖溶液等干擾因素的對膜響應的影響，結果無顯著性干擾；將本法與國標法相比較，驗證了方法的可用性，最終用於在線監測海水中的溶解氧。In chapter one, we propose a new mixed method called characteristics mixed finite element method for a convection - dominated diffusion problems with small parameter e : we handle the convection part whth backward difference scheme along the characteristics, obtain much smaller time - trunction errors and avoid numerical dispersion on the front of the peak curve of the flow : we use a lowest order mixed finite element method to deal with the diffusion part, so this scheme can approximate the unknow function and its following vector with high accuracy at the same time
第一章中我們對小參數對流占優擴散問題提出了新的數值方法? ?特徵混合有限元方法，即對方程的對流部分採用沿特徵線的後退差分格式求解，以保證較小的截斷誤差限並避免了在流動的鋒線前沿數值彌散現象的出現；對流動的擴散部分採用最低次混合元方法求解，以保證格式對未知函數及伴隨向量的同時高精度逼近。由於該方法中檢驗函數可取分片常數，此格式在某種意義上具有局部守恆性質。The results of case a and case b were about the same, thus it was displayed that modifying structure did not cause the bursting under low pressure but the damages of the structure. second, an analytical model was developed to assess the critical buckling problem of near surface interlaminar rectangular defects in the cylindrical part of srmcs under axis and interior pressure loads. the relationships between critical strain value and the parameters of geometry and radius of cylindrical were discussed
在最大壓力為水檢壓力的作用下，應用有限元計算出殼體的整體變形以及不同部位的各種應力（不同應力分量）和位移分量，與試驗結果均比較吻合，證明採用大變形方法分析殼體宏觀應力和變形是合理的， a殼體與b殼體的應力、變形情況基本相同， b殼體發生低壓爆破不是由於結構參數的調整造成，而是由於各種試驗導致的累積損傷造成的。As for raising teachers " ability to improve individual student ' s study, i suggest ; to apply individual guidance according to different students ; to guide students to consciously study teaching materials ; to establish the minimum of teaching purposes ; teachers supervise and inspect students according to the stage of study ; to fully develop creativity and learning initiative of students
對提高教師個別化教學能力提出下列建議：針對學生個別差異進行個別指導；引導學生自覺鉆研教材；規定教學目標的最低達成限度；教師按學習階段進行監督、檢查和落實；充分發揮學生學習的主動性和創造性。分享友人
