Toffoli gate set is chosen as the basis gate library. Each logic gate in the library is a unitary matrix that can be decomposed into a product of a series of elementary transformation which is referred to as a transformation path.

Toffoli门集被选作基本门库，其中每个逻辑门的矩阵都可以分解为初等变换的乘积。

Furthermore, the gate is directly sitting on the undoped layer, and it shows larger gate turn-on voltage and broad gate swing.

此外，闸极直接镀於未掺杂层，因此有大的闸极导通电压宽广的闸极电压操作范围。

Two numerating methods are used in traditional structural design of gate chamber. First,considering the gate frusta to be fastened on the weir body,it is calculated as plane stress problem independently. Then applying the results on the bottom of gate frusta as concentrating load on the weir body,and the weir body is viewed as a elastic foundation beam or plate and unilateral stress analysis was performed.

传统闸室结构计算有两种计算方法，其一是将闸墩视为固端于堰体上，单独进行闸墩平面受力计算，再将闸墩下部的计算结果作为集中荷载作用于堰体上，堰体作为弹性地基梁或板进行片面应力计算。

For high-speed flow of medium, open the gate in local conditions can cause the vibration Cast Gate, Globe, Check Valves of the gate, but they may damage the vibration damper and the valve seat sealing surface, while the throttling damper will suffer erosion of the medium.

对于高速流动的介质，闸板在局部开启状况下可以引起闸门的振动，而振动又可能损伤闸板和阀座的密封面，而节流会使闸板遭受介质的冲蚀。

The petrochemical industry mainly uses API standard gate valve, globe valve and check valves; electricity sector, mainly in power stations using high-temperature pressure valve, globe valve, check valve and safety valve, and part Reducing Valves of the low-pressure water supply and drainage valve butterfly valve, gate valve; the chemical industry mainly uses stainless steel valve, globe valve, check valve; metallurgical industry mainly uses low-voltage large-diameter butterfly valve, oxygen valve and oxygen valves; urban construction department used mainly low-pressure valve, such as urban water mainly in the large-diameter pipeline valve, the main floor, blending the building used by the center line butterfly valve, urban heating mainly in the metal sealing butterfly valve and so on; oil pipeline used mainly flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve and so on.

石化行业主要采用API标准的闸阀、截止阀和止回阀；电力部门主要采用电站用高温压闸阀、截止阀、止回阀和安全阀及一部分给排水阀的低压蝶阀、闸阀；化工行业主要采用不锈钢闸阀、截止阀、止回阀；冶金行业主要采用低压大口径蝶阀、氧气截止阀和氧气球阀；城市建设部门主要采用低压阀，如城市自来水管道主要采用的大口径闸阀，楼寓建设主要采用的中线蝶阀，城市供热主要采用的金属密封蝶阀等；输油管线主要采用平板闸阀和球阀；制药行业主要采用不锈钢球阀；食品行业主要采用不锈钢球阀等。

The first and second stage of the project starts from the Duck Egg Mountain Ring Isle of Zhoushan Island at National Highway329; passes Lidiao Isle, Fuchi Isle, Cezi Isle, Jintang Isle; strides Cengang waterway, Sounding Reefs Gate waterway, Taoyao Gate waterway, Xihou Gate waterway, Jintang waterway, and then it lands on Zhenhai, Ningbo, joining up with the coastal highways.

舟山群岛的连岛工程作为一个广义的概念，正在不断扩大涵义——连岛工程的第一期和第二期桥梁起于舟山本岛329 国道鸭蛋山环岛，途经里钓岛、富翅岛、册子岛、金塘岛；跨越岑港水道、响礁门水道、桃夭门水道、西堠门水道、金塘水道，最后在宁波镇海登陆，与沿海高速公路相接。

He says: The gate that if say a search,is Internet -- the idea that this also is most person -- should trade so will make Gu Ge possesses this gate and the information that flow through the gate.

他说：假如说搜索是互联网的大门——这也是大多数人的想法——那么该交易将使谷歌拥有这扇大门以及通过大门流动的信息。

With the increase of the flux change velocity of the flow passing the gate, the overflowing phenomenon occurred earlier, and the rise of water level in front of the gate during its closing period was of a linear relationship with the flux change velocity of the flow passing the gate.

闸下出流量的变化速率越快，出现漫溢的时间也越短，闸门关闭期间的闸前水位上涨速度与闸下出流量的变化速率呈线性变化关系。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
