All cups have a lid which only opens when the cup reaches the measuring position , preventing loss of sample through evaporation 所有的杯子都帶有蓋子,并且蓋子只能在杯子放置到測量位置時才能打開,防止樣品蒸發。
Results of the measurement taken in august and september 2002 indicated that air quality within the measured locations complied with the directive values adopted by the environmental protection department 2002年8月及9月的測量結果顯示,受測量位置的空氣質素全都符合環保署的指引標準。
In this paper , it is introduced to the influence of cavitation factor , measurement taps , sampling frequency and sampling time on the test result in pressure fluctuation test of the water turbine 摘要介紹了水輪機壓力脈動試驗時空化系數、測量位置及測點、信號采樣頻率及采樣時間等因素對試驗結果的影響。
The law how the controlling parameters , such as the pressure before injecting , total pressure of the gas , the survey distance to exit , affect the discharge coefficient and the mean diameter of the spray is analyzed 通過冷態試驗,分析了液體噴注壓降、氣體總壓等控制參數及測量位置對噴嘴流量系數、霧化平均直徑的影響。
Patricio ahumade junior , the mayor of brownsville , texas , just across the rio grande river from matamoros , mexico , says he will deny federal surveyors access to city land to plot locations for the fence 德克薩斯州布朗斯維爾的市長,剛剛從墨西哥的馬塔莫羅斯穿越格蘭德河,他說他將拒絕聯邦測量員到該城市的土地上為圍欄建筑測量位置。
( 2 ) the measurement error using the 0 . 618 method to measure grounding resistance with short electrode wire is discussed . the analysis results show that the measurement results must be modified , or change the placement of voltage - electrode 通過對模型的計算和討論,發現在短距測量時,傳統的0 . 618法將導致較大的測量誤差,必須對測量結果進行修正,或者對測量位置進行調整。

The improvement on the process of automatically measuring city buildings is one of the most important problems in the current aerial photographic measurement . an approach to measuring a city building based on its structure information is presented . a city building ' s ideal model is first represented by some independent parameters according to its structure information and some image variants which can induce model parameters are defined , and then the initial value of image variants are acquired by combining all kinds of information in the left and right images . finally the optimal location of the building is found for some certain criteria . an implementation of this method is illustrated on flat - roof and rectangular buildings in detail . the experimental results show that not only the method is more automatic than existing methods but also the precision of measurement can satisfy the acquirement of the current aerial photographic measurement , and confirm the method has a good developmental and applied potential 提高城市建筑物測量過程的自動化程度是目前航空攝影測量研究的主要問題之一.文中提出了一種基于結構信息的城市建筑物測量方法.首先根據城市建筑物的結構信息,用幾個相互獨立的參數來描述建筑物的理想模型,并定義能推導出模型參數的圖像變量,然后組合利用左右圖像中各種信息獲得圖像變量的初始值,最后在一定準則下尋求城市建筑物的最佳測量位置.該文以平頂矩形建筑物為例詳細討論了它的一種實現算法.實驗結果表明,這種方法與傳統方法相比較,有較高的自動化程度,且測量精度能滿足現有航空攝影測量的要求,有較大的發展和應用潛力
