厚壁圆筒机械自紧技术是一项有实用价值的工艺技术，它可提高厚壁圆筒的弹性强度和疲劳寿命。

The mechanical autofrettage of thick-walled cylinders is a sort of practical and valuable technique used to enhance its elastic strength of thick-walled tube and increase its fatigue life.

厚壁圆筒机械自紧技术是一项有实用价值的工艺技术，它可提高厚壁圆筒的弹性强度和疲劳寿命。

This paper makes the optimum autofrettage analysis of thick-walled cylinder of the material with different yield strength in tension and compression base on the Mohr's yield criterion.

本文运用莫尔屈服准则对承受内压的拉压屈服强度不同材料的厚壁圆筒进行了自增强分析，得到了依赖于材料拉压比的厚壁圆筒的最佳弹塑性界面半径、最佳自增强内压。

RESULTS: Slitlamp microscopy examination: After bothsided LASIK, the cornea central region was transparency and had no haze. At early stage, epithelium thickened at the edge of the flaps and corneal stroma was slightly irregular, which tended to normal with the time.

结果：BSL术后角膜中央区透明，没有雾状浑浊，早期角膜瓣边缘上皮增厚，变厚的上皮下角膜基质轻度不规则，随时间逐渐趋于正常。

This project studies, use PH indicator (bromic phenol orchid with bromic cresol green), to different object face (be like plastic board, ceramic tile of Brown paper, thick hard paper, thick chipboard, china, bathroom and cotton cloth) planar dirt shoe imprints had a test, made with reagent of salt of sulfur cyanic acid quite, discover PH indicator is more effective.

本项目研究，使用PH指示剂，对不同的客体表面（如塑料板、褐色纸张、厚硬纸张、厚硬纸板、瓷器、浴室瓷砖和棉布等）的平面灰尘鞋印进行了试验，并与硫氰酸盐试剂作了比较，发现PH指示剂更为有效。

The genus Calophyllum of the Guttiferae family is a kind of everygreen plant, mostgrowing in the damp tropic jungle.

红厚壳属植物为藤黄科，藤黄科植物有40余属，1000余种，其中红厚壳属植物约有200余种，主要生长在潮湿的热带丛林中，是一种常青木。

The results were as follows: under 1.5% and 2.5% concentration NaCl stress, Calophyllum inophyllum L. seedings grew more quickly, chlorophyll content, CAT and SOD activity were all increaseing; then along with the content increasing, Calophyllum inophyllum L grew more slowly, chlorophyll content decreased, proline and MDA content increased, CAT, SOD activity increased distinctly, POD activity changed non constat. Calophyllum inophyllum L.

结果表明：1.5%和2.5%浓度的NaCl胁迫时，红厚壳幼苗生长更快，叶绿素含量、CAT和SOD活性均增加；之后随着浓度的升高，红厚壳生长减缓，叶绿素含量减少，脯氨酸和丙二醛含量显著增加，CAT、SOD活性显著下降，POD活性变化不明显。

For carrying out a small physical volume and high reliability of the motor driving and control,by using HIP4081 chip and ALN hybrid integrated technology,a hybrid integrated technology H bridge circuit based on HIP4081 is designed to control bidirectional circumrotation and speed regulation of the motor.

摘 要：为了实现小体积、高可靠的电机驱动与控制，利用HIP4081专用芯片和ALN厚膜混合集成技术，设计一种基于HIP4081的厚膜H桥电机驱动电路，完成了H桥式驱动电路对电机双向转动和调速的控制。

for carrying out a small physical volume and high reliability of the motor driving and control,by using hip4081 chip and aln hybrid integrated technology,a hybrid integrated technology h bridge circuit based on hip4081 is designed to control bidirectional circumrotation and speed regulation of the motor.by practical application,the bidirectional circumrotation/speed adjustment of motor are realized safely and reliably.the products has a small physical volume,fast heat transmission,high efficiency and can operate properly in severe environment.it can enhance the reliability of the drive circuit and the system,and adapt to both military and commercial usage.

摘 要：为了实现小体积、高可靠的电机驱动与控制，利用hip4081专用芯片和aln厚膜混合集成技术，设计一种基于hip4081的厚膜h桥电机驱动电路，完成了h桥式驱动电路对电机双向转动和调速的控制。经实际应用，该电路不仅安全可靠地实现了电机的双向转动和调速功能，且产品体积小，导热性能好，效率高；还能在恶劣的使用环境下安全工作，提高了驱动电路和系统的可靠性，适合军、民两用。

Fruit a usually solitary follicle, sessile or stipitate, dehiscing usually along adaxial suture, sometimes along abaxial one, very rarely circumscissile at base, sometimes indehiscent.

果通常为单生的蓇葖果种子1(或者2)，直立，通常具假种皮，很少无假种皮；种皮厚假种皮有色，肉质；胚乳宿存或无；胚直立；在无胚乳的种子里子叶厚并且肉质，在有胚乳的种子里子叶薄。

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。
