  1. This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time

    該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。
  2. Spindle flowmeter, a new type of differential pressure flowmeter, is used as the sensor of flow measurement. and aiming for a small and intelligent design, we use the mcu named sst89e564rd as the main controller, the leds and the keyboard as the user interface

    本著小型化、智能化的原則，該積算儀採用sst公司的微控制器sst89e564rd作為控制核心，並設計了由數碼管和矩陣式鍵盤組成的人機對話介面。
  3. The design of intelligent differential pressure measurer of steam drum water level

    智能差壓式汽包水位測量儀的設計
  4. Thus, the inner parts are found which are the main factors of the total accuracy loss. this result can offer the basis to improve the design of dynamic measurement system and to increase its measuring accuracy. in order to prove the theory of the error tracing and accuracy - loss diagnosis of the dynamic measurement, two simple measuring system are selected, that is, pressure transducer system and the dynamic measuring system based on differential mutual inductive displacement transducer

    根據建立的動態系統誤差模型，以誤差溯源結果為依據，用bp神經網路分析方法，求得系統各組成單元的精度損失規律，建立其精度損失時變模型，從而找出對測量系統的總精度損失影響較大的內部組成單元，為改進動態測量系統的設計、提高其測量精度提供依據。
  5. The most common method of determining maximum differential pressure across the valve seats is to assign the maximum design or operating pressure the upstream value p1 and assume a downstream pressure p2 of 0 psig

    測定閥門閥座的最大壓差的最常用方法是將最大設計或工作壓力作為上游的壓力值p1 ，然後假定下游壓力值p2為0psig
