150HP-300HP screw air compressor rotor is the German GHH-RAND joint shaft type unit,adopts the third generation asymmetrical dentate 5:6 rotors,The major axis is more reasonable than the choice, the tangent speed of rotors is only 30-36m/s, is far lower than that———60m/s of common air compressors, it keeps 0.003INCH between rotors that will not abrase forever, the space between teeth dropping variance is small, so the backflow loses is slight, Enhances10-12% kf the efficiency compared to the 4:6 dentate, save power 20%, adopts the Swden SKF bearing.

150HP-300HP）螺杆机转子为德国GHH-RAND联轴式机组，采用第三代非对称齿型为5：6的转子，长径比选择合理，其转子的切线速度仅为30'36m/s，远低于一般空压机60m/s 的切线速度，转子之间保持0.003INCH间隙永不磨损，齿间落差小，故回流损失小，比4：6齿型提高效率10-12%，省电20%，采用瑞典SKF轴承，极大延长了主机的寿命。

The Buried Ceramic Far-infrared Element is the selfresearched and technology achievement based on international advanced technlolgy,which has the features of hitech,good compactness clean and hygiene,easy fixing,antiacid,anticorrosion,safe operation,and long lifetime etc,It can be applied for vacuum casting,food-baking,medical purpose and curing methods.

埋入式陶瓷远红处辐身元件，是根据国际先进技术的指引，加上多年的研究，获得的成果。具有科技含量高、整体性能好、清洁卫生、组装方便、耐酸、耐腐蚀，使用安全、寿命长的特点。

The body weights of SSB fed on control rice after feeding on KMD1 for 36h were very significantly lower on day 0 and day 3, and significantly lower on day 9, compared with those of the control. Parasitism rates of host larvae fed on KMD1 by Apanteles chilonis were significantly (3th instar) or very significantly (4th and 5th instar) lower than those of the control host.

二化螟绒茧蜂寄生取食过KMD1的二化螟后，三个龄期幼虫的寄生率都显著下降，其中4龄和5龄达极显著水平；3龄和4龄上的结茧率显著低于对照；蜂蛹历期均短于对照，但仅3龄差异显著；从5龄幼虫所羽化的雄蜂寿命显著短于对照；蜂茧长显著短于对照；而对卵+幼虫期、茧块大小、蜂羽化率及性比均无显著影响。

For this reason and because of the short arcing times, the arc energy developed in the bread is very small.

在分断时，产生的电弧能量是非常小的。这使得真空断路器的使用寿命很长。

The production process in mineral processing has played a good role, improve the beneficiation efficiency, by customers, the rapid development of science and technology in today's electronic devices with constant innovation, production capacity has been continuously strengthened, making the use of efficient equipment, long life, stable performance.

在选矿生产过程中起到了很好的作用，提高了选矿效率，受到了客户的好评，在科学技术发展日新月异的今天，随着电子器件不断的推陈出新，生产能力不断加强，使得设备使用效率高，寿命长，性能稳定。

The electrons on a surface state induced by two-photon absorption (2PA) can be trapped by pyridine or 2, 2'-bipyridine, and have more long lifetime, which is helpful for increasing the third-order nonlinearities.

双光子吸收诱导产生的表面受陷电子能被Py或2，2'-bPy捕获，并且具有较长的寿命，这有利于对激子吸收的漂白，从而提高了三阶非线性。

Cells have not blocked the evolution of extremely long life spans, like that of the bristlecone pine, which lives 5,000 years, or certain deep sea corals, whose age has been found to exceed 4,000 years.

细胞没有阻挡寿命极长的演变一样，美国西南部的松树有5000年的生命，或某些深海珊瑚，其年龄已发现超过4000年。

The optical design of reflectors of microwave sulfur lamp has attracted attention in the lighting field along with the development of MSL.According to the characteristics of MSL system,we program a software for the centrosymmetric reflectors and design a reflector of MSL for the light tube.

前言微波硫灯是近年来国际上崛起的一种新型发光机理的节能光源，因其有高光效、节能、光色好、寿命长、易于维护、低紫外和低红外辐射的综合优点，在国内外&绿色照明&工程实施中倍受瞩目。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
