运用网格生成的微方法以及分块技术，构造了螺旋进气道—进气门—气缸在笛卡尔直角坐标系下的三维伪极坐标网格系统和三维直角坐标网格系统。

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.

松山机场在朔望月里，每逢阴历朔日或望日，受太阳与月球之引潮力(Tide-producing force)方向一致，太阳潮和太阴潮重叠影响，其全日和逐时平均海平面气压比年平均为低；而每逢上弦和下弦时，日地与月地的相对位置成直角，太阴潮和太阳潮相干扰，其全日和逐时平均海平面气压则比全年平均为高。

High-Speed Damping --damping to control fast vertical movements of suspension components caused by road characteristics such as square-edged bumps.

高速阻尼--控制悬挂部件的快速垂直移动的，由路上类似直角边缘的障碍物引起。

The resulting ride is firmer with less dive under braking while simultaneously lessening the amount of force square-edged bumps transfer to the chassis.

结果是较少的刹车前探，和减轻直角障碍物传递给车底盘的力量。

Adjustment of the countertop with the seams of the wall: when the benchmark side of the countertop joints with the jointing side, in case the clearance between splash back of the countertop and the wall is larger than 5MM, use the following method to adjust.

台面与墙面缝隙的调整：接驳台面基准边与对接边合拢后，对于非直角墙体，如台面挡水与墙体面缝隙超过5MM，我们可以通过下面的方法调整，将两块台面紧靠墙，将两块台面的后挡水边靠拢在一起，这时两块台面的前端有间隙，就用卷尺测量前端间隙的尺寸，在后挡水处按间隙尺寸做标记，连接前端点和后面的标记划线。
