查询词典 cone

Cone and seed development was observed from 1993 to 1998 in wind-pollinated Keteleeria davidlana Beissner var. formosana Hayata trees grown at Taipei Botanical Garden.

The new bit ′ s cone and bearing are much larger than those of the three cone bit with the same size,therefore the new bit can bear a greater WOB,thus,the life of the bearing and cone can be prolonged and then the penetration rate can be raised and the length of bit run prolonged.

与相同钻头尺寸的三牙轮钻头相比，该新型钻头的牙轮尺寸和轴承尺寸要大得多，因此，它可以承受较大的钻压，从而可以提高轴承和牙轮的使用寿命，进而提高机械钻速和钻头的使用寿命。

Models have been developed for predicting sound seeds and total seeds per cone by means of the cone cuttingfor Chinese fir. Number and quality of seeds per cone have been analysed and estimated.

本文利用球果切开法建立了预测杉木全果饱满种子数和种子总数的预测模型，同时对杉木球果中种子的产量和质量作了估测和分析。

The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

结果表明，在循环水流量为65 立方公尺/h，水温24.5℃，氧气流量为0， 1， 2，……，10 L/min的条件下，溶氧与氧气流量回归方程为y=0.1009χ^2+0.059 4χ+5.958 8(r=0.9927)；根据物料平衡原理，推算出氧气锥的最大氧气利用率为84.56%；在最大氧气利用率的条件下，依照尼罗罗非鱼的耗氧率计算模式，推算出工厂化养鱼系统需配置氧气锥的台数。

Cone vacuun mixing drier increases vacuun drying/ heating/ cooling. etc functions on the basis of cone helix mixer.Because it uses widy.during the period of manufacture much attention has been paid to rationality and convenient.Special design at shaft seal/screw support and thickness of cone plate is increased.

圆锥型真空混合干燥机，是在圆锥型螺旋混合机上，增加了真空干燥/冷却等功能，由于用途广泛，因此特别重视制造过程中的合理性及便利性，该设备在轴封/螺旋支撑部及锥体板厚等方面增加特别的设计，基本结构与圆锥型螺混合机相同。

The Cone Shell method is often used in cases where homogenisation is not necessary. The pile is formed by depositing material in a single cone from a fixed position. When this conical pile is full, the depositing of material moves to a new position and a new cone is formed against the shell of the first one.

锥壳法通常用在均匀化要求不大的场合，料堆可以在一个固定的位置单独堆成一个锥状，这个锥形料堆堆满了，堆料工作转移到另一个新的位置进行堆料，新的料堆紧靠第一个料堆的外壳形成。

In Gravitarmata margarotana oviposition selection period, the total contents of volatiles in healthy needle branches were higher than healthy cone branches, and the total contents of volatiles in red cone tree were lower than green cone tree.

在油松球果小卷蛾危害期，虫害果枝中挥发物的含量均高于健康果枝，油松健康果枝挥发物的含量在化学诱导后明显增加，化学诱导与植食性昆虫取食对油松产生了相似的诱导反应。

The transducer assembly (102) includes an inner driver cone (114), an outer driver cone (112) and a dust cap (116) constructed such that the direct path length from the voice coil (110) to the outer driver cone periphery is substantially equal to the distance from the voice coil to the dust cap peak.

换能器组件(102)包括一个内部激励器锥(114)、一个外部激励器锥(112)和一个防尘帽(116)，于是从音圈(110)到外部激励器锥周边的引导路径距离基本等于从音圈(110)到防尘帽顶部的距离。

In fishing,the sliding cone blocks enter the fish cavity easily acted by a guide shoe and a guide cone,slide downward by its own weight,produce relative displacement to the guide rail slope,and the radial distance between its tooth face and the spear rod increases until it touches the inner wall of the fish cavity; while lifting the drilling string,the guide rail slope on the spear rod forces the sliding cone blocks to bite the inner wall of the tubing fished.

打捞时在引鞋和导锥的作用下滑牙块能够顺利进入鱼腔并依靠自重下滑，沿导轨外伸直至其齿面与鱼腔内壁接触；随后上提钻柱，矛杆上的导轨斜面迫使滑牙块咬紧被打捞油管内壁，当油管严重偏磨使一对滑牙块卡在磨穿位置时，另一对能有效卡在未磨损部位，同时外筒限制了油管外胀变形。
