Design of energy saving rudder geometries in the propeller slipstream .
螺桨迹流中的节能舵形设计。
He did not grant independent existence to the noneuclidean geometries .
他不承认非欧几里得几何的独立存在性。
But none of the mathematicians believed that these basic non-euclidean geometries would be physically significant .
但数学家们无人相信这些基本的非欧几里德几何必然有物理意义。
Or the customer 's latest revisions have bad drawings with open geometries and other inconsistencies , and hence require unplanned hours at the engineer 's desk-hours the customer isn 't paying for .
On the revolution series of machining centers , the mti control does not create the excessive stress sometimes associated with high speed machining , allowing fluid tool motion for complicated part geometries .
Like beetles and butterflies , their color comes not from pigments but from the refractive geometries of their surface coverings , which don 't degrade over time . ( Some beetle colors even shine true after nearly 50 million years . )
Dr lisi had been tinkering with some smaller geometries .
lisi博士之前只是做一些小维几何的改进工作。
Under general relativity any form of energy couples with spacetime to create the geometries that cause gravity .
广义相对论认为任何形式的能量都要与时空相匹配,以此创造出提供重力的空间几何形态。
The residence is regarded as a signature example of shingle-style architecture , a genre known for simple geometries , flat , shingled surfaces and horizontality .
With this approach I then set about wrapping my foot in tracing paper , then binding it up in masking tape and then drawings various geometries onto and over the form of my foot .
