Throttle valve the Faxin for needle-shaped cone or belt gaps Cone, the thread for Fagan small teeth, when round-hand, the distance is Faxin mobile, liquid through the area is small, this can cause considerable local resistance, high pressureliquid through the puncture wounds on the consumption of energy and relief.

节流阀的阀芯为针形锥体或带缺口的锥体，阀杆的螺纹为细牙，当旋转手轮时，阀芯移动的距离不大，液体通过的面积也就很小，此时可以造成很大的局部阻力，高压液体通过小孔时消耗能量而降压。

Steve Roush, Chief of Sport Performance with the U.S. Olympic Committee. My experience has been that in the dialogue I've had with other national Olympic Committee staff members is that there is far less pressure when it comes to who's getting the tickets, who's getting the accreditations at the Olympics. Many times, decisions they have to make are political decisions on taking care of all the ministers who have decided they want to come to the Olympics.

Steve Roush，美国奥委会Sport Performance 的负责人说到我曾经和很多别的国家的奥委会成员做过类似的交流，对他们来说，选派谁参加奥运会，如何分配入场券并不会面临很大的争议和压力，很多时候他们做决定的时候必须很谨慎的照顾到所有相关政治人物的态度，这些人的态度对参加奥运至关重要。

It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

Principle of self-aligning uniformly distributed load for work roll bearing in operating side is presented for the first time.

为达到轴承延寿的目的，已在接触力学、润滑与磨损、加工制造、材料冶金等方面开展了一系列的理论与实验研究，轴承自身的质量有了很大的提高，但轧辊轴承的寿命和工作可靠性仍未能得到大的改善和提高。

Through electron micrograph, sepiolite is found to have net fiber structure shaped by straw bundle.

海泡石一超细水泥的实验看出，超细水泥具有粒径小、比表面积大、水化速度快的特点，在加入海泡石后，海泡石并没有对超细水泥的水化速度产生很大的影响，能够使超细水泥的一些施工性能得到更好的改善，同样对超细水泥的胶结强度、抗折强度、抗冲击韧性起到提升的作用。

Chinese women's volleyball team this year in China and Switzerland Classic Classic in the first two games have made the eight-game winning streak of success, the most satisfactory aspect of the block is the team, especially the two main font hand Mr Shipman and Ma Yun-Wen to the other side of the block a lot of pressure, a new bright spot in the largest women's volleyball.

今年以来中国女排在中国精英赛和瑞士精英赛的前两场比赛中取得了八连胜的佳绩，最令人满意的环节莫过于全队的拦网，尤其是两名主力副攻手薛明和马蕴雯的拦网给了对方很大的压力，成为新女排最大的亮点。

It has been found that there are some texture flaws such as large grain、badly distorted twin and streaky structure. But recrystallization grains ofaround 19μm in diameter on average are obtainable through heat treatment at300℃for 30min by air-cooling, meanwhile the twin and streaky structurethat would weaken the plasticity of alloy are eliminated; significant elementsare holding temperature、holding time、cool-down methods. Mechanicalproperties of tube are obtained, simple tension elongation ratio of arc testsample increases from 10.8% to 20.1%, elongation ratio with elastic internaldie of tube increases from 8.0% to 14.9%.

研究结果表明：挤压成型的AZ31镁合金管材组织中存在变形程度很大的孪晶、大尺寸晶粒、丧失了进一步变形能力的条带状组织等易导致后续塑性加工时变形不均，引起断裂的组织缺陷；采用最佳等温热处理工艺以20℃／min加热至300℃保温30min后空冷处理可以使试样平均晶粒直径从挤压态的50μm细化为19μm，同时基本消除上述组织缺陷；明显影响热处理效果的因素为保温温度、保温时间、冷却方式；室温下，采用最佳工艺热处理前后管材弧形试样的单向拉伸伸长率由10.8％提高至20.1％，管件的自由胀形极限伸长率由8.0％提高至14.9％。

During the meeting on Sunday, the government's representatives, Zhu Weiqun and Sitar, the lead negotiators in previous discussions, pointed out that the riots had created new obstacles for resuming contact."However," they added,"the central government still arranged this meeting with great patience and sincerity."

在周日的会谈中，中国政府的代表，也是以前数次谈判的代表，朱维群和斯塔，指出：之前发生的骚乱为双方重新接触制造了很大的障碍，"尽管如此"，他们补充道："中央政府仍然以最大的耐心和诚意来进行此次会谈。"
