proper star 中文意思是什麼
proper star
解釋
選定的星-
Proper motion of a star
恆星運動方向與視線之間的夾角。 -
Therefore, a fast moving but far away star could have the same proper motion as a slow moving but nearby star
所以，一顆遙遠而移動速度高的恆星的自行，可能會和一顆近而移動得慢的恆星差不多。 -
Usually, proper motion of a star is very small and can only be detected if we observe the star for decades. there is one important exception however
，但恆星的移動非常非常緩慢，非要經過數十年的時間，再加上精確的量度，才能夠偵測出來。 -
You should follow the installation instructions for the luminaires, such as installing away from combustible surface ( wall paper, wooden false ceiling ), allowing sufficient room for heat dissipation ( particularly luminaires fitted with tungsten halogen lamps ), ensuring effective earthing connection ( such as adding star and spring washers at the earth terminal ), and adopting proper anchorage to support its weight
燈飾應按照指示安裝，注意要遠離容易燃燒的表面（例如墻紙、木製假天花） ，預留足夠的散熱空間（尤其是裝有鎢絲鹵燈的燈飾） ，確保有效接地（例如在接地終端加上菊花介指和彈弓介指） ，並因應燈飾的重量，選用適當的安裝方法（例如大型的吊燈，須選用拉爆螺絲等） 。 -
Then the pro ? models have been input into pro ? m, an automatic mesh generating software, to create the mesh system for numerical simulation. after defining some proper boundary condition, the flow analysis have been performed through the use of star ? d, a powerful cfd software. with some careful analysis of the simulation results and comparison of the two models, some guiding principles for the design optimization of the compressor inlet turning tubes have been concluded
論文主要工作包括：通過對壓氣機進氣彎管幾何形狀的深入分析，利用三維建模軟體pro / e生成其三維幾何模型；利用網格自動生成工具pro - am ，根據pro / e生成的三維幾何模型生成了數值模擬所用的計算網格；對壓氣機進氣彎管內部流動進行了詳細的氣動計算，對原進氣彎管與新型進氣彎管的計算結果做了對比分析，對其結構的優化設計提出了指導原則。
