Some resin material may decomposes so it setscrew speed in mid-speed such as 45-75%, In plastic step setting screwback pressure is very important, Higher screw back pressure ,higherquality of product screw back pressure make resin structure order, Moldingproduct is beautiful and volume stable. But ,it maybe flow if screw

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

One such spot where our soldiers fought back, and repelled, the Chinese incursions was at Razang La near Chushul, in the Himalayan heights. On November 18, 1962, 114 soldiers of the 13th Kumaon fought till the last man, and last bullet, in sub-zero temperatures, to beat back the huge Chinese army.

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

根据Ar-Ar热年代学研究，精确测定了早二叠世伸展变形和晚二叠世挤压变形的峰期时代分别为290Ma和259Ma.2、提出了关于哈尔里克山南麓小铺一带变质带和变质作用的新认识根据显微观察资料和特征变质矿物的出现，把小铺一带的变质岩由SW向NE方向依次划分为黑云母带、石榴石带、十字石带、红柱石带和矽线石带等变质带；初步确定该区的变质作用属于中温-低压型，变质作用发生的时代为290Ma左右，是该区早二叠世地壳伸展的产物。3、首次提出哈尔里克山南麓在石炭纪可能发育弧后盆地的新观点根据哈尔里克山南麓原"居里得能组"岩屑砂岩的碎屑锆石SHRIMP U-Pb定年，确认这套地层的沉积不早于晚泥盆世，很可能是石炭纪，而不是前人所说的前寒武纪；结合对其区域地质背景、源区位置和沉积环境分析，推测该区石炭纪可能为滞后弧后盆地和弧后隆起区构造背景。4、进一步证明哈尔里克山不发育与岛弧演化相关的泥盆纪岩浆活动根据对代表性闪长岩和花岗岩的锆石SHRIMP年代学研究获得的新资料，结合该区已有相关资料的综合研究，确定哈尔里克山岩浆岩分别形成于奥陶纪-志留纪和石炭纪晚期-二叠纪，不存在泥盆纪的岩浆岩，进而认为该区泥盆纪不属于岛弧环境。5、重建了哈尔里克山古生代以来的地质演化过程根据区域资料以及本次研究所获得的资料，把哈尔里克山古生代以来的构造演化划分中奥陶世-早志留世为岛弧、中志留世-晚泥盆世为弧后区、石炭纪弧后伸展、二叠纪为后碰撞伸展与挤压、中生代差异隆升和晚新生代陆内再造山过程等构造阶段。6、初步估算了哈尔里克山地壳缩短率和缩短量根据前中生代地层褶皱估算的哈尔里克山南山口-口门子、石城子-白石头和沁城-小铺三条剖面的地壳缩短率分别为16.2%、19.8%和20.1%，相应的地壳缩短量分别为4.3km、9km和11.3km。

Brad Paisley -- Letter To Me 写给自己的信 If I could write a letter to me And send it back in time to myself at 17 First I'd prove it's me by saying look under your bed There's a Skoal can and a Playboy no one else would know you hid And then I'd say I know it's tough When you break up after seven months And yeah I know you really liked her and it just don't seem fair All I can say is pain like that is fast and it's rare And oh you got so much going for you going right But I know at 17 it's hard to see past Friday night She wasn't right for you And still you feel like there's a knife sticking out of your back And you're wondering if you'll survive You'll make it through this and you'll see You're still around to write this letter to me At the stop sign at Tomlinson and Eighth Always stop completely don't just tap your breaks And when you get a date with Bridgett make sure the tank is full On second thought forget it that one turns out kinda cool Each and every time you have a fight Just assume you're wrong and dad is right And you really should thank Mrs.

如果我能写封信，寄回给十七岁时的自己。那里有一个啤酒罐和一本"花花公子"，没人知道你把它们藏在那儿。然后我要说那很令你难受，当你交往了七个月的女孩儿与你分手，是啊我知道你好喜欢她，那似乎不很公平，但我只能说那是短暂的痛苦而且也极少发生。哦，你有着美好的未来，但我知道十七岁时很少有谁人去想周五晚上以后的事儿。她不适合你，你却依然心如刀绞，不知能否活下去。但最终你能熬过这一切而且你会看到你仍然好好的并写这封信给我。在Tomlinson与第八街的交口处，停车信号时一定要将车停住而不仅仅是点一脚刹车。当你和Bridgett约会要确信油箱是加满的，再仔细想想，别太在意了，那个女孩儿并不很酷。每一次的争执，就只当你是错了而爸爸是对的。而且你真要好好感谢Brinkman老师，她为你花费了那么多额外的时间，好像她看到了地下的钻石，她不停地打磨直到你闪闪发光。
