查询词典 exhalation

Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.

环境氡主要来自岩石、土壤，而目前环境氡研究中与地质环境结合很少，为此作者以物理场为基础，运用气体运移的费克扩散定律和达西定律，建立起壤中氡浓度分布与大地—大气间氡交换理论模型，首次在理论上将环境氡与地质环境结合起来；论文中从理论上讨论了模型中各参数对空气中氡浓度的影响，发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异；通过面状氡源条件下的氡运移模型实验，研究了介质中氡的运移与分布，实验数据表明氡浓度随深度的变化规律可用指数函数描述，在放射性元素分布均匀的条件下，介质中不同深度和同一深度不同点的氡浓度随时间而变，但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的；同时研究了不同介质间氡的交换，并验证了所建立的理论模型；运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布，取得了较好的效果。

在CL图像的基础上，我们用拉曼扫描的方法分析了这3类不同结构的锆石。1008和356cm-1峰显示了相同或相似的图像特征，而它们的半高宽图像有相同或相似的图像特征。

This paper reports the results of highly precise zircon SHRIMP U-Pb dating of quartz albitite in the volcanic-sedimentary series of the Tuolugou cobalt deposit, Golmud, Qinghai. Analyses of eight spots presented 206Pb/238U ages of 455 to 483Ma with a weighted mean age of 468±9Ma, which represents the timing of submarine volcanic exhalation in this area. Therefore, the age of the host rocks of the Tuolugou ore district is redefined as Ordovician, which implies that regionally the main part of the Naij Tal Group should be Early Paleozoic in age.

青海格尔木驼路沟矿区赋矿火山－沉积岩系中的石英钠长石岩样品锆石SHRIMP U-Pb精细测年结果表明，该岩石具有一组8个测点构成的455~483Ma的206Pb/238U年龄数据，加权平均年龄为468Ma±9Ma，应代表本区海底火山喷流作用的时间，因此重新厘定了矿区内含矿岩系的时代为奥陶纪，同时，这一年龄指示区域上纳赤台群主体的时代应为早古生代。

Expiratory time is measured from the beginning of exhalation to the beginning of the next inspiration .

呼气时间测定是呼气开始到下一次呼气开始。这里的&呼气&应该是&吸气&吧？麻醉学相关临床指南汇总！

Some filtering facepiece respirators have an exhalation valve which can reduce breathing resistance, reduce moisture buildup inside the respirator and increase work tolerance and comfort for respirator users.

有些随弃式呼吸防护口罩还带有呼气阀，呼气时可以降低阻力，减少面罩内湿热空气的积聚，提高工作中呼吸器使用人员的耐受性和舒适性。

In their Respiratory Protection standard, 29 CFR 1910.134, OSHA does require that respirators be stored to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture, and damaging chemicals, and that they be stored to prevent deformation of the facepiece and exhalation valve.

在OSHA 的呼吸保护标准29CFR1910.134中，规定呼吸器应储存在安全、无污染、无尘、无日光照射、无极端温度、无高湿、无有害化学物的环境中，储存中应防止呼吸器面罩和呼气阀的变形。

a mandatory testing device to prevent drunk driving is proposed.it can mandatorily test whether and how much a driver or a sailor on watch drunk.only when the alcoholicity of the exhalation breathed out by the people tested is normal,small type or automobiles can startup,the person on watch of a large ship can register as working.otherwise,if the alcoholicity is overproof,small type ships or automobiles can't startup,and neither does the device allow the person on watch register as working and it can inform the captain via alarm.in this way,drunk driving problem can be solved effectively only by setting a simple device.

该装置具有强制检测机动车驾驶员和船舶值班人员饮酒状态的功能，当被测人员呼出的气体酒精含量正常时，机动车或者小型船舶可以启动，大型船舶的值班人员可以记录为值班；当被测人员呼出的气体酒精含量超标时，机动车或者小型船舶无法启动，大型船舶的值班人员则不能记录为值班，同时可以通过报警器通知船长。这样，仅通过安装使用这样一个简单的装置，就有效地解决了酒后驾驶机动车和船员酒后值班的问题。

Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.

在硅质岩方面：冈底斯构造带侏罗系硅质岩主要属泥质硅质岩，在各个碰撞结合带和弧后盆地中均有产出，主要的产出状态有：①在碰撞结合带中呈岩块产出，构成蛇绿混杂岩的重要组成部分，属蛇绿混杂岩型硅质岩；②在弧后或弧间盆地中呈厚度不等的泥质硅质岩夹层产出，常具&硅灰泥&特征，属弧后深水盆地型硅质岩；③呈夹层状产于弧火山岩系中，属火山热液或火山喷气型硅质岩。

The chemical composition of pyrite, galena and sphalerite clearly shows that there are dual features of synsedimentary deposits and subma rine exhalation-sedimentary deposits in the ore formation in this area.
