The authors, by means of safety testing and measuring as well as checking calculation for the bottom gate, discovered safety hidden trouble in gate system, and put forward the suggestion of treatment.

通過對底孔閘門的安全檢測及復核計算，發現了閘門系統存在的安全隱患，并提出了處理建議。

Adopting advancing mining which is non-advance bottom gate and raserve gate along the gob.

這是單一突出煤層開采的新途徑新工藝.

We also find that SiN_x, used as the gate-insulator-layer of the bottom gate TFT, can increase ( by about 20%) the crystalline volume factor ( Xc) of μ c-Si thin film deposited thereon.

同時又發現，以sin x為柵絕緣層的底柵TFT，對隨后生長的硅基薄膜有促進晶化的作用（約20%）。

The flat bottom gate provides full perimeter seating against the seat, eliminating pocket in the bottom of the seat that can trap process media and prevent the valve from fully closing.

平坦的閘板底部與閥座之間能夠實現全周長閥座密封，避免閥座出現可能淤積流體介質、妨礙閥門完全關閉的底部洞隙。

Three plane gates, including the middle, low and bottom gate, are provided in the conveyance shaft, and connected by telescope joint-type hoist rods which are capable of being lengthened and shortened.

在輸水豎井中設有中、低、底3扇平板擋水閘門，由可伸縮的套接式拉桿連接；

Therefore, while depositing μ c-Si on SiN_x to fabricate the bottom gate TFT, this effect must be taken into account.

沉積底柵TFT的微晶硅有源層時，必須計入該影響。

The modified technology improved the temperature field and fluid field of liquid steel in arc furnace, decreased the etch of bottom and gate of furnace and intensified the whirl of surface of liquid steel.

該項改進的技術改善了電弧爐內鋼液溫度場和流場，減少爐底和爐門局部侵蝕，加強鋼水液面的旋轉。
