In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

Applying the software ADAMS for dynamic simulation and Pro/E for three-dimensional design creates the mechanical system of virtual prototyping model of the 200t crawler crane. The models of the drag bar, the spring backstop, the luffer rope and the crawler in the system are established well by ADAMS/View module. The dynamic simulation of the complete mechanical system is researched at series of work condition, which occurs possibly the crawler crane boom backward tipping as the crawler crane unloads suddenly.

本文应用虚拟样机技术动力学仿真软件ADAMS，结合三维实体设计软件Pro/E构建了200t履带起重机的虚拟样机机械系统模型，并利用ADAMS/View模块完善了系统中拉板、弹簧式防后倾装置、变幅钢丝绳和履带模型：研究了履带起重机突然卸载时可能发生臂架后倾的一系列工况下，整机机械系统模型的动力学仿真。

Four 4-month-old wethers fitted with heal cannulas were fed a constant concentrate and a hay in baled, long chopped (4~6 cm, LCH), short chopped (1~3 cm, SCH) and fine ground (0.5 cm, FGH) form in a 4×4 Latin square design to evaluate the effects of forage particle size on nutrient digestion in the hindgut and total tract of sheep.

为探讨粗饲料颗粒度对反刍动物饲粮养分在后肠道及全消化道消化的影响，本试验将饲粮中的粗料青干草进行整草、长铡草（4~6cm，长草）、短铡草（1~3cm，短草）和粉碎（0.5cm，粉草）4种颗粒度的机械加工后进行定量饲喂（4×4拉丁方试验）。

The dyeing performance and color fastnesses of the pigments extracted from dry mulberry fruits in silk fabric dyeing were analyzed and compared.

对从桑椹中提取的色素在蚕丝织物上的染色性能和染色牢度进行了分析、对比，确定了先媒后染和先染后媒的染色工艺条件。

The principle of low temperature Tar-removing device is the use the characteristics of tar from gas phase to liquid phase at low temperature.

低温除焦油装置的原理是利用气相焦油在低温时形成液相的特性，冷水机组将常温水制冷后，通过喷淋低温水使燃气降温，气体中的焦油充分液化后与水一起排出进入筛检程式过滤。

This paper analyses the changes of narrative point of view and focalization,and reveals the theme of the story——through the text,Hamingway objectively presents a certain impasses in the male-female relationship and shows women's strong inner feelings and desires in such condition.

草稿题名跟完成稿略有不同，为&Cats in the Rain&，即&雨中的猫&的&猫&为复数形式。作品最后连同其它七个短篇完稿于1924年1月之前[。1](P29)《雨中猫》语言简洁，情节也很简单：一对美国夫妇来到意大利一家旅馆中，年轻的妻子看到雨中的一只猫后心生同情，决定去把猫捡回来，但到了雨中猫却已经不见了。

Inspired by the face painting of the operatic character of Hou Yi, Montblanc's latest masterpiece in 18K white gold features the heroic archer's masks in flawless red and black lacquer on its cap and an exquisite engraving version on its rhodium-plated 18K gold nib.

该杰作灵感来自京剧中的英雄人物后羿，由18K 白金打造，笔帽上的后羿脸谱以黑漆镶嵌工艺华贵呈现，而18K 金笔嘴上的脸谱雕刻亦巧夺天工。

From the results we found (1) the α power in the control group decreased dramatically but not in the experimental group,(2) after meditation,α power in the frontal area of meditators increased more than that of the control subjects (after resting-EEG recording).

在α波空间分布的特性及差异性方面，初步发现(1)实验组在禅坐中的α波减少程度不如控制组般显著；(2)实验组禅坐后前脑的α波会比控制组休息后多。

By using electroporation transfects,the TGF〓expression vector were introduced into HL-60 cells.Thecells were allowed to grow for 1 day before beingsubjected to selection for the ability to grow in mediumcontaining 600ug/ml geneticin.Stable cell clones resistantto G418 sulfate were obtained after 2-3 WK growth withdrug-containing medium.Southern blot hybridization wascarried out.RNA slot have higher expression of TGF〓mRNA in HL-60 transfected.All results followed suggestedthat TGF〓 have suppressed the maliganant phenotype of HL-60 cells.
