压力不足

Since there still exist many handicaps that affect the reform during the practice, for example, lack of inspiration, pressures from the economic environment, and the restrictions of the social development competence, great importance should be attached to the major questions, that is, how to clarify the relationships, how to supply supporting systems and how to catch the main points, and so on.

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.

在低压低渗透气藏的压裂改造过程中，常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题，一是压裂液滤液对低压低渗透气层造成的水锁损害；二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的，对碱敏性储层造成碱敏损害，降低储层渗流能力；三是地层压力低，压裂液返排能量不足，当前各油田采取的措施主要是&液氮伴注&技术，但是&液氮伴注&技术增加了压裂的费用，而且液氮存放也存在较大问题。

In order to deeply reveal the smoothing mechanism of roller burnishing and to overcome the difficulty in the selection of the burnishing cross feed dependent mainly upon experiences and hand feel, the roller burnishing process is taken as an issue of plane-strain mechanics and the micro-plastic deformation area is determined on the basis of the Von-Mises yield criterion and by using the Boussinesq-Flamant solution. Then, the contact pressure distribution is obtained based on the Hertz contact theory, and the stress distributions in the burnishing tool and the workpiece are respectively revealed.

为深入了解滚柱滚压表面光整机理，解决目前滚压量选择完全凭经验和手感的不足，将滚柱滚压加工过程视为平面应变力学情形，利用Boussinesq-Flamant问题的求解并根据Von-Mises屈服准则得出了滚压局部发生微塑性变形的区域，根据Hertz接触理论得出了滚压接触压力分布及滚压过程中工件和工具的应力分布。

It shows in three aspects:(1) The imbalance of supply and demand of human resources allocation in West China put enormous pressure on the enhancements of natural resources, environment protection and the human resources;(2) The situation of the human resources in West China hiders the local economic from increasing and changing.

西部地区人力资源配置失衡是众多&合力&作用的结果，既有历史的积累，现实的制约；又有自然的压力，体制的束缚等多方面原因。归纳起来，主要有四个方面的原因：主观认识的偏差。主要表现为忽视资源配置的重要作用和对人力资源亥质特征认识的不到位。（2）经济水平的制约。（3）教育投入的不足。（4）配置方式困局限。

VSA helps sense oversteer and understeer, and can adjust brake pressure at each wheel and/or reduce engine power to help restore the driver's intended course.

VSA的帮助感觉过度和转向不足，并可以调整每个车轮制动压力和/或降低发动机的动力，以帮助恢复驱动程序的打算课程。

When high-strength sheet metal straightening,it will have a Turtle phenomenon,its process control model is obviously inadequate hydraulic pressing,the Shaft of straightening machine Often broken and the work of roller bearings damage Frequently.so it is necessary for the fuel tank pressure,displacement and the roll rotation of the motor current,torque drive signal for analysis.

当矫直高强度薄板时，会产生龟背现象，其工艺控制模型中液压压下明显不足和矫直机传动轴经常断，工作辊轴承经常损坏问题，于是很必要对液压缸压力，位移和各辊的电动机转数，电流，传动扭矩信号进行分析。

The improved slide plate used for speed-up turnout can on one hand provide endure, reliable and constant tightening of inside of stock rail and, on the other hand, can flexibly match the gauge adjusting of stock rail. Besides, roller plate can reduce the switching resistance and the deficient displacement of tongue rail so as to realize the reliable switching.

改进型滑床板一方面能持久、可靠的扣压基本轨内侧，保持扣压力的恒定，另一方面能够方便、灵活的配合基本轨的轨距调整，此外滚轮滑床板减小了道岔转换阻力，降低了尖轨的不足位移，确保道岔转换可靠。

Advanced optimum control scheme was presented after the analysis of shortage in traditional three wash control scheme of boiler water level.

分析了传统三冲量锅筒水位控制方案的不足，引入压力参数作为补充控制量，提出了改进的优化控制方案。

Advanced optimum control scheme was presented after the analysis of shortage in traditional three wash control scheme of boiler water level. In the new control scheme, the pressure of steam was used to be a complement control parameter.

分析了传统三冲量锅筒水位控制方案的不足，引入压力参数作为补充控制量，提出了改进的优化控制方案。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
