Based on application of 3D body-fitted numerical grid with a curvilinear coordinates system and the theories about turbulent flow and the laminar flow, the new techniques that the independent variables were expressed by co-variable velocities were applied to solve the problems about flow around a high-speed car body for the first time.

The evolution of the hydrodynamic field was cyclic and each cycle may be divided into centrifugal flow stages when the basin subsides and receives deposits, and centripetal flow stage when the basin uplifts and is eroded.

地下水动力场演化具有旋回性，每个旋回可以分为两个阶段：①盆地沉降接受沉积时期的泥岩压榨水离心流阶段；②盆地抬升剥蚀阶段的大气水下渗向心流阶段。

Methods Clinical data of 51 patients with PRF were retrospectively analyzed. Among the 51 cases, 12 were treated with the ureteroscopic holmium: YAG laser lithotripsy and stenting after it, 29 with retrograde intubation under cystoscope, 10 with retrograde intubation under cystoscope and percutaneous nephrostomy.

Based on plentiful isotopic dating data and geological studies, the authors, in this paper, discuss the geological meanings of the two isotopic ages given by Lapierre et al., and conclude:① Mesozoic volcanic activities in Zhejiang are most frequent in 130～83 Ma, that is, from the early to late Cretaceous but not the late Jurassic;② The Jiande and Moshishan groups are nearly in the same period and not in an upper—lower stratigraphic relationship with each other;③ The period of 110～100 Ma is a transitional stage from the early high-K calc-alkaline dacite—rhyolite associated with diorite—granodiorite） to the late basalt—rhyolite（associated with K-feldspar granite—alkali granite）.

本文就Lapierre等文中124 Ma和97 Ma两个年龄的地质意义、幕次划分以及浙西与浙东火山岩时代对比作出评论，并厘定浙江中生代火山岩时代归属，提出：①浙江中生代火山活动时代为132～83 Ma；②浙西建德群与浙东磨石山群火山岩并不存在上下关系，地质接触关系、古生物组合和大量同位素定年数据都不支持Lapierre等的浙西与浙东火山活动幕次的对比方案；③ 110～100 Ma为早期高钾钙碱性英安岩—流纹岩（伴生闪长岩—花岗闪长岩）向晚期玄武岩—流纹岩（伴生钾长花岗岩—碱性花岗岩）过渡的转折期。

Early Cretaceous granitic volcanic-intrusive complex in Xiushanlinchang of northeastern Da Hinggan Mt. consists mainly of rhyolite, rhyolite ignimbrite-trachytic dacite, trachyandesite formed in eruptive cycle stage and adamellite porphyry-geode syenogranite-graphic alkali feldspar syenogranite formed in hypabyssal invasion stage.

大兴安岭东北部秀山林场一带的早白垩世花岗质火山－侵入杂岩体由喷发旋回期的流纹岩、流纹质熔结凝灰岩－粗面英安岩、粗安岩和浅成侵入期的二长花岗斑岩－晶洞正长花岗岩－文象碱长正长花岗岩构成。

So it is very important to research in seepage calculation and monitoring of earth dam.

因此，对土石坝的渗流计算和渗流监测问题进行研究具有十分重要的意义。

The test results validated that the design principle of MR damper, the deduced rheological equation and the calculating equation of damping force are correct.

测试结果证实了本文所提出的磁流变阻尼器的设计原理、推导的流变学方程和阻尼力计算公式的正确性。

The air conditioner forced draft fan ventilates the way to have longitudinal and the crosswise two kinds generally, the lateral ventilation the air current overflow sectional area is big, the wind speed is small, easy to create the big area the dead angle, but longitudinal ventilates the air current the overflow sectional area to be small, the wind speed is big, the dead angle area is very small.

冷风机通风方式一般有纵向和横向二种，横向通风的气流过流断面积大、风速小，容易造成较大面积的死角，而纵向通风气流的过流断面积小，风速大，死角面积很小。在使用条件许可的情况下，应该尽可能采用先进的纵向通风方式。

It connects different factories or enterprises by the way of transmitting material flow or energy flow, to form industrial symbiosis networks by sharing the resource and mutual exchange by-products. Under this pattern,"by-product" of one producing process may be the raw material of another process. In order to explore material closed circular, energy conservation system and minimum discharge of the waste, it set up the circular pathway by imitating the natural circular system as"producer—consumer-- decomposer"in the industrial system.

它通过物质流或能量流传递等方式把不同工厂或企业连接起来，形成共享资源和互换副产品的产业共生组合，使一家工厂的废弃物或副产品成为另一家工厂的原料或能源，模拟自然循环系统，在产业系统中建立"生产者—消费者—分解者"的循环途径，寻求物质闭路循环、能量多级利用和废物产生最小化。
