查询词典 effective diameter of thread

A hotwire anemometer was used to measure the jet velocity at the exit of the precessing jet nozzle and the power spectrum density was obtained afterwards in order to analyze the precessing feature of the jet. It is shown that an obvious precession motion is generated in a nozzle even with a large expansion ratio E=10 and a small length-to-diameter ratio LD=2. The precessing frequency is mainly dependent on the nozzle diameter and the intake flow rate, increasing with the enhancement of the flow rate and with the reduction of nozzle diameter.

采用热线风速仪测量旋进喷嘴出口射流的速度，并对该射流进行功率谱分析以研究其旋进特性，结果表明，实验所用的膨胀比E=10、长径比L/D=2的喷嘴同样能产生明显的旋进射流，旋进频率主要取决于喷嘴的尺寸和射流的流速，并随流速的增大和喷嘴直径的减小而增大。

Main factors influencing the joint lockup performance are determined by experiments and analysis, and the basic relationship between the lockup performance of robot joints and the influencing factors, including piston diameter, cavity diameter, material of friction ring, friction ring average diameter and viscosity of hydraulic oil, is obtained.

通过相关的实验研究及分析，确定了影响机器人关节锁紧能力的主要因素，获得了机器人关节锁紧能力与活塞尺寸、内腔尺寸、摩擦环材料和尺寸及液压油粘度等影响因素的基本关系。

Additionally, the growth of the pathogen was obviously affected by cultural media. The morphological characters such as colony color and diameter, and production of fruit body of the fungus growing on PDA, 10% V8, apple leaves dextrose agar and apple leaves extraction dextrose agar media were different. The fungus formed colonies of about 8mm in diameter and did not produce fruit bodies and aerial hyphae in 1 month incubation on PDA. However it formed the similar size colonies as on PDA and produced fruit bodies and aerial hyphae on 10% V8 and LDA media in the same incubation period. Very small colonies (2mm in diameter) and fruit bodies were found on LEDA media in the same incubation condition. These results indicated that successful isolation of M. coronaria from apple leaves depended on suitable isolation method and cultural media as well as fresh samples.

不同培养基上菌落形态、大小和产孢情况差异也很大，培养1个月（25℃）后PDA上菌落黑褐色隆起，表面蚯蚓粪状，无气生菌丝，无子实体和基内菌丝；10% V8培养基上菌落中央隆起，黑褐色，表面生少量气生菌丝，边缘放射状，基内菌丝深褐色，有子实体；苹果叶片葡萄糖琼脂培养基上菌落平坦，黄褐色，表面生茂密的金黄色气生菌丝，基内菌丝深褐色，有子实体；苹果叶片煎汁葡萄糖琼脂培养基上菌落有明显的不规则隆起，黄褐色至黑褐色，表面生少许气生菌丝，菌落生长缓慢，无基内菌丝，分生孢子盘菌落表面生，菌落直径仅2mm左右，而在其他培养基上的菌落直径可达6－8mm，说明培养基质、分离方法均对苹果盘二孢的分离培养和生长发育有明显的影响。

Methods Resting diameter of brachial artery and diameter after hyperaemia,change rate of blood flow and internal diameter were detected by high frequency ultrasound to evaluate vascular endothelial function of healthy people in different races.

利用高频超声检测汉族与维吾尔族健康人肱动脉静息管径、反应性充血后管径、内径变化率及血流量变化率，对两组血管内皮功能进行评价。

In the jig design process, mainly locates by V shape block and the support plate, depends on the straight clamp and the spring clamps, drills turns diameter two to be supposed to use long trades quickly drills the wrap, when drills turns the diameter incline hole uses the plane incline the jig body, when drills turns the diameter incline hole uses is the horizontal-type drilling machine, when face milling 2 V shape blocks and the milling cutter cannot interfere ,therefore V shape block altitude must reduce, the jig design must be convenient, be simple.

在夹具的设计过程中，主要以V形块和支承板来定位，靠直压板和弹簧来夹紧，钻拐径两孔应采用长型快换钻套，在钻拐径倾斜的孔时采用平面倾斜的夹具体，在钻拐径倾斜的孔时使用的是卧式钻床，铣面时2个V形块与铣刀不能干涉，因此V形块高度要降低，夹具设计要方便、简单。

All afferent and efferent vessels were measured and recorded. Results Anterior scrotal artery coming from superficial external pudendal arteries is divided into medial and lateral branches at lateral penile base and spread out on lateral and anterior surface of scrotum. Diameter of internal branches are(0.54±0.34)mm and (0.69±0.09)mm. Lateral scrotal artery(100%present rate, 0.62±0.19mm in diameter)originating from obturator artery distributes to lateral side of scrotum.Posterior scrotal artery is separated into lateral branches and septal scrotal artery at posterior scrotal ploe. The former(0.8±0.1mm in diameter)spreads to lateral and posterior region of scrotum.
