By using the CFD software FLUENT, the inner-flow field of centrifugal fans with ruled-surface impeller versus with enveloping surface impeller has been simulated. The static pressure distribution, the dynamic pressure distribution, the total pressure distribution, the turbulent intensity and the speed vector of the two kinds of centrifugal fans are then analyzed and compared. From the calculating results, we found that the pressure distribution, the speed vector and other parameters of the two kinds of centrifugal fans are basically same. This implies that the tool-path generating arithmetic for the machining of the impeller can meet the aerodynamic requirements of the centrifugal fan. Furthermore the method can provide proof for designing department to establish sound manufacturing tolerance for impeller.

最后采用CFD软件FLUENT，利用标准k-ε湍流模型，采用分离隐式求解器，分别对直纹面叶轮离心通风机和包络面叶轮离心通风机整体风机内部三维流场和单个通道流场进行了数值模拟计算，在计算结果的后处理中，对相同坐标值处的静压力、动压力、湍流强度和速度矢量等参数进行了分析与比较，结果表明：在相同的计算参数条件下所得到直纹面叶轮离心通风机和包络面叶轮离心通风机内部流场差别不大，从而揭示所采用的叶轮数控加工的刀位规划方法的规划误差对流体机械动力性能的影响不大，这也为设计部门制定合理的叶轮加工公差提供了依据。

In brief, the process involves growing uniform crystals to a certain diameter, thinly slicing the crystal to very precise tolerances, edge rounding the form factors, polishing them into smooth wafers, then carefully packaging the wafers in a class 100/1000 room for shipping to customers. The main advantages of the VGF process include its scalability, low stress, high mechanical strength, and a defect rate that is orders of magnitude lower than conventional compound semiconductor crystal growth processes.

简言之，过程包括成长统一的晶体到某一个直径，薄薄的限制晶体到非常精确的公差，边缘圆整到形态要素，抛光他们成光滑的晶片，然后包装晶体在一个100/1000级别的空间为运输到顾客，VGF过程的主要优点包括，可测量性，低压力，高机械强度和一个比常规化合半导体晶体成长过程数量级低的过失率。

The experimental results show that the mean particle size of griseofulvin precipitated by RESS is smaller than 1, 0μm, narrow distribution and 95％ fine particles is smaller than 1. 0μm. Increase of the pre-expansion pressure, the extraction temperature, the expansion chamber temperature, the spraying distance, the concentration of cosolvent and decrease of the nozzle diameter resulted in decrease of the particle size under the operating condition studied. Enhancement of the pre-expansion temperature resulted in increase of the particles size. The SEM of GF shows that the shape of original is atactic and a wide size distribution, but the microparticles obtained by RESS is reverse. Similar melting points and XRD patterns were observed for the original material and the precipitates obtained by RESS.

实验结果表明，用含夹带剂的RESS法制备的灰黄霉素微粒的平均直径在1μm左右，且分布均匀，95％微粒在1μm以下，仅用CO〓作为超临界流体制备的微粒与上述方法制备的微粒的平均直径和分布相似，只是产量太低，而用机械法制备的微粒平均直径在3μm左右且分布较宽；不同的过程参数对沉析微粒尺寸有不同的影响，预膨胀压力、膨胀室温度、溶解温度以及夹带剂浓度的提高或增大，均可使沉析微粒的直径变小；预膨胀温度提高，所得微粒的直径变大；喷射距离的增加，沉析微粒的直径变小；喷嘴直径越小，由此制得的微粒的直径就越小；根据实验结果还可知道，通过理论计算的马赫盘处微粒的直径可以较好地估计出膨胀室中收集到的微粒的直径。

Be a large-scale, the file time is high, the equipments perfect and super and large business sail mothe r － the Shanghai Caoan machinery mark, be have a foothold in the high point of departure, high personal status on the programming, on the design the principle that persistence" make people the center", press the factory's principle of management fixed position: Break the tradition is subjected to be limited by the shop front, the office building demonstration space small, depend the mode of the manpower sale, provided to gather the demonstration and play to show, trade etc.

Coordinating among these parameters is crucial but the basic element of the evaluation is still the operation weight of compactors, which represents an equivalent pressure of the vibratory drum. For the two kinds of single drum vibratory compactors, fully hydraulic drive and mechanical drive, compacting capability of the former is certainly higher than that of the later.

这些参数的相互协调至关重要，但其评价的最基本要素仍然是压路机的工作重量，并且集中体现在振动轮的&当量压力&，对于两种类型的单轮振动压路机，当然是全液压机型的压实能力远远大于机械传动机型。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
