  1. Increasing ultrasound intensity in the range of cavitation threshold and cavitation peak value, decreasing monomer concentration and increasing the temperature make the induction period shorter. under optimized reaction conditions, the conversion of ba can reach 90 % in 11 min at high n2 flow rate the viscosity average molecular weight of the obtained pba reaches 5. 24 106. the molecular weight of pba varies with ultrasonic irradiation time, indicating that the ultrasonic induced emulsion polymerization is dynamic and quite complicated, polymerization of monomer as well as degradation of polymer occurs concomitantly

    一、實現了無常規化學引發劑存在下的超聲輻照引發丙烯酸正丁酯（ ba ）間歇乳液聚合，制備了pba納米粒子，在11min內轉化率達到90 ，分子量達5 . 24 10 ~ 6 ，隨反應時間的延長而降低，表明超聲輻照引發乳液聚合是一個動態的復雜過程，單體的聚合和聚合物的降解同時發生。
  2. The review summarizes the development of ultrasound contrast agent for targeted drug and gene delivery to tumors. from these study we can draw a conclusion that ultrasound - targeted microbubble therapy will become a new method in treatment of tumor

    隨著各種兼具診斷治療雙重作用的超聲探頭和靶向微泡造影劑包括納米級微泡造影劑的研製，以及對超聲生物學效應的深入研究，超聲微泡介導腫瘤靶向治療將為臨床腫瘤的治療帶來新的希望。

    陣列處理的高分辨技術一直是國內外十分關注的研究熱點，其中高分辨多目標定向技術是國內外集中力量研究的重點，該項技術的突破對聲納、雷達、地質勘探、生物醫學工程及水中兵器均有重要意義。
  4. So, he pushed open the door with the weak rattle in its throat, stumbled down the two steps, got past the two ancient cashiers, and shouldered himself into the musty back closet where mr. lorry sat at great books ruled for figures, with perpendicular iron bars to his window as if that were ruled for figures too, and everything under the clouds were a sum

    於是，他推開了門那門喉嚨里輕微地咕嚕了一聲，一個趔趄落下兩步階梯，走過了兩位老出納員，橫沖直撞地擠進了羅瑞先生那長了霉的后間密室。羅瑞先生坐在龐大的帳本面前，帳本的格子里寫滿了數字。他窗戶上垂直的鋼條似乎也是用來寫數字的格子，而在雲天之下的每一件事物則是填在格子里的數字。
  5. It has been found that certain bats emit squeaks and by receiving the echoes, they can locate and steer clear of obstacles ? ? or locate flying insects on which they feed

    人們已經發覺，某些蝙蝠發出尖叫聲並靠接納回響來鎖定和避免阻擋物? ?或者找到它們賴以為生的昆蟲。
  6. However, wigner - ville distribution is n ' t enough effective applied to multicomponent signals processing for existing crossed items, sometimes signal items completely ca n ' t be distinguished from distribution for serious disturbance of crossed items. in addition, we can utilize the wigner - ville distribution to reduce the random noise of signals in that wigner - ville distribution is n ' t enough sensitive to noise. in theory, radon - wigner transform of lfm signals produces a distinct maxima ( peak ) in the radon - wigner plane, so it describe effectively the feature of the lfm signals and suppress effectively the crossed items along with wigner - ville distribution. we can utilize the radon - wigner transform to reduce the random noise of lfm signals in that the noise distrbute as dot at random in the radon - wigner plane

    另外，維格納-威利分佈是完全有噪的，但它對噪聲是不敏感的，因此可以利用維格納-威利分佈實現對含噪信號的去噪處理。理論上線性調頻信號的radon - wigner變換在radon - wigner平面上以尖峰形式表現，因此radon - wigner變換能夠有效描述線性調頻信號的物理特徵，抑制在維格納-威利分佈中產生的交叉項。在radon - wigner平面中隨機噪聲是呈點狀隨機散布開的，因此利用radon - wigner變換還能對含噪線性調頻信號進行去噪處理。
  7. Additionally, up to 25 percent more carbon dioxide is released to the atmosphere each year, above that from deforestation, from the decomposition of what the loggers leave behind, " asner said in a statement

    艾斯納在一份聲明中說，選擇性伐木對很多植物和動物的影響都是消極的，而且還增加了腐蝕和火災的發生。另外，這樣還會使該地區每年向大氣中釋放的二氧化碳量增加25 。
  8. Time - frequency analysis and parameter estimation of noisy polynomial phase signal ( pps ) are the general problems in such fields as radar, sonar, communication, biomedical application, seismic signal analysis and so on

    噪聲背景中多項式相位信號的時頻分析和參數估計是雷達、聲納、通信、生物醫學、地震信號分析等領域需要解決的共性問題。
