Anterior clinoid process and the upper margin of the optic canal were ground by using a high-speed drill according to the location of the tumor.

取下骨瓣，磨除蝶骨嵴，剪开硬膜，分开外侧裂。依据肿瘤的位置用微钻磨除前床突和视神经管上壁。

By improvement of coiling device hydraulic systems and equipment spares structure, production efficiency of slitters is raised.

通过对卷取装置液压系统和设备部件结构的改进，成功提高了纵剪机组的生产效能。

It studied many factors such as blank holder pressure, anti-pressure, clearance between punch and bottom die, and parameters of dentiform on blank holder, analyzed the influence of these factors' change to stress and strain field in distortion area and the appearance of shear crack, summarized the appropriate ratio of blank holder pressure and anti-pressure, and the best range of other factors.

从压边力、反压力、相对冲裁间隙、压边圈齿形参数等各种因素出发，分析了这些因素的变化对于变形区应力应变场与剪切面裂纹产生的关系，并得出了压边力与反压力的合适配合比例，以及其他参数的正确取值范围。

In order to verify the model mentioed above, the mathematical simulation of geotemperature field has been carried out. The thrust nappe sheat zones are handled with two ways: 1 they are treated as constant heat sources in terms of q=τμ, that is, the quantity of frictionally generated heat is constant; 2 as heat conduit with high thermal conductivities and with fluid flow in fault zones.

为了进一步检验上述逆冲推覆复合叠加构造模型的可信程度，开展了地温场数值模拟工作，按复合叠加型岩石圈热结构给定各种热物性参数，逆冲推覆剪切带以两种方式处理，一是把它作为定热源按q＝τU，即按摩擦生热量级大小取值；第2种是把它作为热通道处理。

METHODS: Rat cerebral cortex was obtained sterilely, made into monoplast suspension by the mechanical separation, and then incubated in the serum-free MEM/F12 medium, supplemented with B27 neurotrophic additive for 1 week. Subsequently, cells were passaged.

无菌条件下取胎鼠大脑皮质，剪碎后机械分离法制作单细胞悬液，加入含B27神经营养添加剂的无血清MEM/F12培养基进行培养，1周后传代。

All patients were performed open decompression operation on the legs with microincision.At the same time,the patients were given dehydration,diuresis drugs.The wounds were deferred the suturation time. Results:Among the 37 patients,33 patients were fully recovered.

均采用小切口减张术（即在小腿内、外侧各取纵行切口，长2~3cm，游离皮下组织直至深筋膜，打开深筋膜，将剪刀伸进切口内，分别向近、远端潜行剪开深筋膜，上至膝关节下，下至内踝）治疗。

Results The succeed rate of ESWL by one time was 85%, 12 cases were treated by second time with ESWL ,16 cases were treated by cutting open ureteral orifice with cystoscopy, 3 cases were treated by ureterolithotomy.

结果 一次性碎石成功率为85%（187/220），12例行二次碎石，16例行输尿管口扩张剪开术，3例行输尿管切开取石术。

The range of The weighted coefficient b can be abtained and Mises yielding criterion can be linearly replaced by it.

建立了加权三剪应力屈服准则，导出了根据σs/τs 的比值选择权系数b的关系式，以及能够线性代替Mises屈服准则的加权系数的取值范围。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
