Fourthly, according with the analyzing of flow measurement, we research the main problems needed to be solve in the process of measurement, such as analysis and measurement of the internal resistance, selection of excitation frequency, stable signal datum mark and restraining common mode interference, restraining for serial mode interference and working frequency interference ; transporting and shielding the flow signal, constant current excitation and magnetic field equalizing, flow measuring
第四，根據對流量測量問題分析的，深入研究了設計過程中需要解決的主要問題。如內阻分析與測量;勵磁頻率的選擇;穩定信號基準點與抑制共模干擾;串模干擾與工頻干擾抑制;流量信號傳輸與屏蔽;恆流勵磁與磁場補償;流量測量點的選擇等。 -
Luminaires that conform to the safety standard should bear proper markings of rated voltage, rated frequency, rated power, number and type of lamp bulbs, model number, mark of origin ( manufacturer nametrade mark ) and symbol for suitability or non - suitability for direct mounting on combustible surfaces where applicable
符合安全標準的燈飾須有適當的標記，包括額定電壓、額定頻率、額定功率、燈泡的數目和類別、型號、原產地標志（製造商名稱或商標） 、是否適宜於直接安裝在可燃物質表面的標志等資料。 -
The type, direction and frequency degree of land use change not only reflect the process of the space - time dynamic change of the earth ' s surface landscape and become the most salient landscape mark of the earth surface system, but also become the base of rebuilding the equilibration of land use - ecosystem - productivity
土地利用變化類型、變化方向和速率以及變化的頻繁程度不僅反映了地球表面景觀的時空動態變化過程，成為地球表層系統最突出的景觀標志，而且還成為了重新建立土地利用? ?生態? ?生產均衡的基礎。 -
A method of pitch mark determination for a speech, includes : acquiring a fundamental frequency point and fundamental frequency passband signals by using an adaptable filter ; detecting a number of passing zero positions of the fundamental frequency passband signals ; and generating at least a set of pitch marks from a number of passing zero positions
一種決定語音音高標記的方法，系藉以找出一語音之一組音高標記，此決定語音音高標記的方法系利用一可適性濾波器取得一基頻點與一基頻帶通訊號；求取基頻帶通訊號之復數個過零點位置；然後經由復數個過零點位置產生至少一組音高標記。 -
The magician changes a bill that works well mark to in a twinkling a seal completely of counteract the lock lock to live of the video frequency in the copper tube play to show
魔術師將繩子繞在手掌中，打開后三條繩子竟然變成了一條三色長繩，接頭神奇的消失了。視頻演示： -
Using the feature : there exists distinct edge contour between the characters and the background in color image, we give a color image text extraction algorithm - tea ( text extraction algorithm ), which makes the use of cedo to process edge detection of color image, then, adopts morphologic dilation technology to form region image, and combines the area - growth algorithm to mark the candidate text blocks, finally, determinates the correct text block by analyzing the density of text block and the space frequency feature
利用彩色圖像文本區域與背景之間存在明顯邊緣輪廓的特點，本文給出了彩色圖像文本提取演算法? tea （ textextractionalgorithm ） 。該演算法首先利用cedo進行彩色圖像邊緣檢測，然後採用形態學膨脹技術生成區域圖像，並結合區域生長演算法標記候選文本塊，最後通過分析文本塊密度和空間頻率特性來判定真正的文本塊，從而較好地完成了彩色圖像的文本提取。
