Adopting the three heading construction method to simulate twelve kinds of construction projects, confirm reasonable construction orders and left and right tunnel face interval, systematically analyze and research the changing law of the tunnel deformation and surrounding rock stress in soft and cracked condition of surrounding rock,bring forward pertinent advices against construction disease; Build the deep buried tunnel model in middle section of tunnel , separately adopt the central heading bench cut benching method and the central heading full cross method to simulate ten kinds of construction projects, establish the reasonable construction orders, sidestep length and tunnel face interval, which are due to the deep buried tunnel, systematically analyze and research the change law of the tunnel deformation and surrounding rock stress in the section with good surrounding rock condition, bring forward the reasonable construction projects which can make sure of construction safety and save construction time; Because the central wall is disturbed many times during constructing process, its displacement and stress distribution is very complex.

富溪隧道进口段依照实际的浅埋偏压状况建立模型，采用三导洞法开挖模拟了12种方案，确定了合理的施工顺序和左右主洞掌子面错距，系统地分析研究了软弱破碎围岩浅埋偏压段施工的隧道变形和围岩应力变化规律，提出了防止施工病害的针对性建议；洞身段按深埋隧道建立模型，分别采用中导洞台阶法和中导洞全断面法模拟了10种方案，确立了适合深埋隧道的合理施工顺序、台阶长度和掌子面错距，系统分析研究了围岩较好深埋段施工的隧道变形和围岩应力变化规律，提出了兼顾施工安全和节省工期的合理施工方案；由于受到多次扰动，中隔墙的位移和应力变化规律较为复杂，通过对各种方案的对比分析，得出了中隔墙在施工不同阶段的位移变化规律、应力变化规律和应力分布规律，尤其对于浅埋偏压段隧道施工时中隔墙位移和应力变化规律做了深入研究，提出了合理的施工建议。

The leaf area index, photosynthetic potential and dry matter accumulation were lower for the SHY rice than those for the CK at the early growth stage, and their differences were not significant between the two rice types at heading, and were greater for the former than the later after heading. The root-shoot ratio at each growth stage, root bleedings from heading to maturity, grain-leaf ratio, translocation percentage of the matter from stems and sheaths and harvest index of SHY rice were greater than those of CK.

超高产水稻各生育时期的根冠比、抽穗至成熟的根系伤流量以及粒叶比、茎鞘物质运转率和收获指数均显著高于CK；超高产水稻花后叶面积指数、剑叶叶绿素含量、光合速率、PSⅡ最大光化学效率均显著高于对照，非光化学猝灭系数显著低于对照。

The heading determination model based on two total positioning systemis used to calibrate the ship alongshore heading together with the GPS attitude determination equipment, time synchronization system via receiving GPS second pulse to synchronize the two kinds of data is also designed.

结合GPS姿态测量设备，通过采用数据插值融合技术，进行舰船组合航向测量。为了提高组合航向测量的精度，设计了通过接收GPS秒脉冲对两种航向测量数据进行时间同步的系统。

To create a heading row in an existing table that does not have one, you need to apply an AutoFormat that does have a heading defined.

若要在没有标题行的现有表格中添加标题行，你需要应用一个定义了标题的自动格式套用。

Namely the heading, the inside address, salutation, the subject heading, the body of the letter, the complimentary close, the senders signature and identification, the designation, etc.

即：信头，信内地址，称呼，事由主题，正文，结尾套语，发信者的签字和身份，头衔等。

These results are in agreement with previous results for heading date in rice,and the results provide further information.which indicate that both epistasis and QE interaction are important genetic basis for determining heading date in rice.

对水稻抽穗期QTL的定位结果与前人研究基本一致，并进一步证实了上位性和QE互作效应是水稻抽穗期的重要遗传基础。

Hexagonal bolts are usually formed with cold heading. The process is classified as open-die forging and therefore its die design is less complicated. The mushroom-like head has to be sheared into hexagonal shape and the amount of the scrap is somehow significant especially for heading with short bolts or high alloy material. There is an increasing demand in increasing the gross profit by increasing the yield of workpiece material.

六角螺栓头端通常以冷间顶铁成形製程来製造，由於冷间顶铁属於开模锻造，模具设计较容易，但需以剪缘模再对蕈状头端冲剪成为六角头，此剪缘后的废料量不容忽视，尤其对於长度较小的螺栓，或其它应用於紧扣件的高级合金而言，藉由减少废料以提高產品毛利的需求日益迫切。
