Effectiveness scarce, demand assignability is a value of the four basic elements, demand for real estate and commodities need to have the capacity to pay, we will not, the effectiveness of commercial housing is scarce in nature and that consumers do not have sufficient purchasing power, the market value can not be achieved, the current real estate market demand can be broadly divided, using the minimum requirements, the public demand for improved housing, urbanization process needs field and offshore demand, the demand for investment or speculative demand and the housing problem is livelihood security, the need to increase public finance, but this is the need, not demand.

效用稀缺，需求可转让性，是价值构成的四个基本要素，需求是对房地产商品有需要而且具有支付能力，两者缺一不可，商品房具有效用和稀缺性，消费者没有足够的购买力，市场价值就不能实现，当前房地产市场的需求大致可分为，动拆迁的需求，市民住房改善的需求，城市化过程中的需求，外地和境外的需求，投资需求或者是投机需求，住房保障问题是民生问题，需要公共财政加大力度，但这是需要，不是需求。

General hydrology information collecting way can"t satisfy the requirement of present hydropower already, mostly it represents in inaccuracy and unreal time. It enhances inconvenience about flood analysis and decision-making to fight against flood, makes the results inaccurate and postposition, also, the reservoir"s dynamic capacity cant ignore in period of flood.

常规水利资料搜集方式已经不能满足当代水利水电工作的需要，主要表现在它的不准确性和非实时性上，这就给洪水分析、防洪决策等工作带来了很大程度的不便，使得所得的结果不精确和后置，并且越是洪汛期动库容所占的比例越是不能忽略。

We do not separately skeletonize the renal ein and artery during LPN. We think that indiidual essel skeletonization is unnecessary, and might een be counter-productie for the following reasons:1it is not mandatory for achieing adequate clamping;2 it might result in renal artery asospasm;3 it increases the risks of iatrogenic ascular injury with serious sequelae;4 some hilar fat might cushion the renal essels, minimizing crush injury to the endothelium by the clamp, especially in cases of atherosclerotic renal arteries;5 it requires ≈ 30 min of precious operating time, detracting the surgeon from the primary goal of the procedure.

在LPN过程中不分离肾动静脉轮廓，因其并无必要，如分离可能由于以下原因达不到预期目的：1 不必充分夹紧；2可能导致肾动脉痉挛；3增加医源性血管损伤及其严重后遗症的风险；4肾门脂肪可能对于肾脏血管起到缓冲作用，减少钳夹对于上皮组织的挤压伤，特别是对于动脉粥样硬化的肾脏动脉病例；5 导致达到手术目的的时间中花费大约30分钟宝贵手术时间。

针对集体逃生舱工作状态复杂的特点，考虑了在水下和水上两种情况下的静稳性以及水上情况下的动稳性，同时研究它从水下到水面的运动情况，以证明集体逃生舱不会从水面跳出和发生倾覆。

During the past few years, many studies have demonstrated that arterial pressure variation is neither an indicator of blood volume nor a marker of cardiac preload but a predictor of fluid responsiveness.

美国麻萨诸塞州波士顿哈佛医学院的Michard博士指出，在过去的几年间，许多研究都显示动脉压的变化既不是血容量的指标，也不是心脏前负荷的标志物，而是液体反应性的预测因子。

The study found that by using both the PMT program and the Hybrid Model of Executive Function the ADHD problem behavior of pre-school age children was reduced, attention span was improved and hyperactive and argumentative behavior was reduced. In addition, there were improvements in problems related to ADHD, including care-giver well being. This study showed that the combination of the methods was very effective and situational dependence, but the Hybrid Model of Executive Function should be continually applied to produce the best benefit. The study findings further indicate that although this method is very effective in a family environment when applied constantly, for other situations like in school, the method must be altered to fit those other situations and be performed continually in that environment in order to achieve the same results.

研究发现，在透过父母管教训练方案对执行功能技巧能力进行训练之后，的确可以降低学龄前ADHD儿童的症状行为，改善注意力问题、过动冲动问题，以及对立反抗行为，此外，也能够降低因症状行为所衍生的相关问题，如：照顾者的困扰程度等等；另一方面，本研究同时发现其具有「成效性」及「情境性」，即：技巧能力训练必须不断的进行，才能获得显著的治疗效果；而针对家庭情境进行处理时，治疗效果仅能展现於家庭情境下的不适应行为，若想要向外延伸到学校情境，除了需要针对该情境进行相关能力训练之外，仍然需要家长针对家庭情境所需的能力持续进行训练，才能够将家中的良好行为延伸至学校情境之中。
