If your package has a large size - to - weight ratio , you may need to consider your package s dimensional weight when calculating your shipping rates 如果您的包裹的體積重量比較大,則在計算托運費率時,便應(yīng)考慮包裹的體積重量。
Ergonomic features : reduced torque reaction and vibration , light weight , quieter operation , high power to weight ratio , comfortable trigger and grip 人工控制特點:減少扭矩的反作用力和震動,輕質(zhì),消音操作,高能效比率,扳機抓握舒適。
The results showed that the thrust - weight ratio reached 1 . 04 for the launch weight 5400kg in the condition of specific impulse near 600s 結(jié)果表明:在發(fā)動機工作比沖接近600s的情況下,對于起飛質(zhì)量為5400kg的飛行器而言,推重比為1 . 04左右。
If your package has a large size - to - weight ratio , you may need to consider your package s dimensional weight when calculating your shipping rates 體積重量如果包裹的尺寸與重量的比值很大,您可能需要在計算運輸費率時考慮包裹的體積重量。
For this reason , extreme radiation hardness and high power / weight ratio solar cells , which can work properly in van allen belts , must be developed 因此,為了能使通信衛(wèi)星在vanallen輻射帶正常工作,必須要有一種強抗輻射并且具有較高重量比功率的太陽電池。
It is not only high in the power - weight ratio and large in the load stiffness and applied force but also agile in electric system and high in precision 它既利用了液壓系統(tǒng)功率?重量比高、負載剛度大及作用力大的特點,又充分發(fā)揮電氣系統(tǒng)靈活、精度高的優(yōu)勢。
To optimize specific impulse to 700s or 800s , the thrust - weight ratio could be improved to 1 . 23 or 1 . 41 , it is enough to achieve the launch requirement for this vehicle 進一步將比沖優(yōu)化至700s或800s ,可以將推重比提高至1 . 23或1 . 41 ,這樣就完全能夠保證發(fā)射任務(wù)的完成。
The performance of next generation maneuverable missile was predicted by taking into account its important parameters such as lift to drag ratio , empty weight to total weight ratio and effective load 在考慮導彈空重、有效載荷和氣動特性的情況下,預(yù)測了未來先進飛航導彈的性能。
Pmts have following advantages : very good stiffness weight ratio , large feed speed , high machine precision , simple mechanical structure etc . compared with the traditional machine tools 與傳統(tǒng)的數(shù)控機床相比,并聯(lián)機床具有剛度比重大、響應(yīng)速度快、加工精度高、機械結(jié)構(gòu)簡單等優(yōu)點。
The effects of catalyst , reaction temperature , operation parameters and the weight ratio of acrylic acid to epoxy resin on the properties of ea resin were investigated 摘要以環(huán)氧樹脂和丙烯酸為原料,研究了投料比、反應(yīng)溫度、催化劑、操作方法等因素對合成ea (環(huán)氧丙烯酸)樹脂性能的影響。
