Rational new method for checking ring gauge is put forward in this paper. For pitch less than 0.5 mm check plug is used to inspect size on virtual effective diameter and simple effective diameter, but for pitch over 0.5 mm, check plug is only used to inspect size on virtual effective diameter, simple effective diameter is measured by double ball.

提出了对于螺距不大于0.5 mm的螺纹环规，采用校对规检验作用中径及单一中径；而对于螺距大于0.5 mm的螺纹环规，则采用校对规检验作用中径，双球法测量单一中径。

The Jet Balloons will be used for the first time in Holland. They are special balloons, equipped with a valve. They should be inflated five minutes before the players enter the pitch, so that the entire stadium will be an ocean of red-white colours. The moment the referee leads players unto the pitch, the balloons should be released. They go straight up due to the valve and produce a great sound. If over 30, 000 spectators do so at the same time, the effect could be very special indeed!

这些气球的使用，在荷兰应该是第一次，它们都是一些特殊的气球，它们将在球员们进场前在体育场上空飘荡大约5分钟，所以，体育场在这段时间将会是一个红、白色的海洋，而等到这些球员都进场后，这些气球就会被释放，同一时间，它们将伴随着巨大的响声向上飘起，它们的数目可能超过3万多个，到时候景象会是非常壮观的！

When the pitcher throws to the batter, it is a strike if he swings and misses, if he hits the pitch into foul territory, or if he does not swing at a pitch in the strike zone.

当投手把球投向击球员后，如果击球员挥捧而未击中，把球打入界外地区或球在好球区之内而来挥棒击球，都算是一击。

Tall oil was used as a model compound of the pitch in the pulp suspension to study the effects of calcium soaps on the pitch deposition with and without fibers.

利用塔罗油作为新闻纸厂浆水体系中树脂的模型物，分别在有纤维和无纤维存在下研究了钙皂对树脂沉积的影响。

D. When the ratio of louver pitch to fin pitch is LP/FP=1.25, the integral performance of the louvered fin radiator is favourable.

分析百叶窗间距和翅片间距的比值对气侧传热和流动性能的影响，当百叶窗角度为27°，LP/FP=1.25 时，具有较好的综合性能； e。

A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.

基于船舶操纵性分离建模理论，采用荷兰船模试验水池B系列螺旋桨的敞水试验结果，利用Akima插值获得了不同类型的调距桨在不同螺距比下的四象限推力系数和扭矩系数，求得调距桨的推力和扭矩，建立了调距桨船舶的平面运动数学模型。

During a low speed, the pitch angle is a constant, wind turbines keep on the optimum speed ratio between the pitch and wind so as to absorb the maximum energy.

该风力机在低风速时桨距角不变，保持最佳叶尖速比以获得最大风能；在高风速时储存或释放部分能量，桨距角仅完成限制最大输出功率，减少机械应力，风能储存在风力机机械惯性中，减少力矩冲击。

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.

为了能够在较小的计算区域内不改变叶型而真实地反映出任意栅距比时的内部非定常流场，并避免近似仍采用相位后滞周期性条件，结合本文发展的网格技术，给出了一种新的实施方法，首次将动、静叶片数不等的离心式/轴流式叶轮机械转子、静子计算区域组合在一套结构化计算网格中，动/静叶排间的滑移界面完全按内场处理，避免了每一时层内，滑移界面处边界条件的迭代计算；并保证了每一时层，滑移界面处流动参数的守恒特性。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
