NF 99 is a heavy duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 99 contains chlorinated additives, fatty oil and special lubricity fortifiers to impart quick release of chip from tool even under extreme high cutting pressure. The low viscosity ensures good cooling and flushing properties, which are essential for high speed machining.

NF 99是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的重負荷切削，含有氯化物、脂肪及特殊潤滑添加劑，增進其極壓及潤滑性能，就算在高切削壓力下，也能使屑片容易與刀具分離，低的黏度確保了足夠的冷卻及沖屑性能，都是高速切削所必需。

The occurrence of this disease with age, body type, environmental factors, the human body skin regulate body temperature and the role of secretion and excretion and in the case of cold, skin vasoconstriction, caused by sweat and sebaceous gland function is low, to prevent the divergence and to reduce skin heat lubrication, while the formation of dry skin, cuticle cracking, scaling, skin inflammation ‥‥ and so on, often associated with soap, disinfectant contact would eliminate the skin of lipids, an increase of the loss of moisture, in addition, can change the skin more dry and older because of the lack of sebum, to reduce sebum secretion, skin showing dry, rough, with a fault in bran-like crumbs off the winter came, the weather is cold, plus hot water bath or multi-use soap, will lead to skin Worse still, dry, itching is also more severe.

本病与年龄，体质，环境因素的发生，人体皮肤调节体温的分泌和排泄和冷，皮肤血管收缩的汗水和皮脂腺功能造成的，作用是低的情况，以防止分歧并减少热量润滑皮肤，而皮肤干燥，角质形成开裂，脱屑，皮肤发炎‥‥等，经常用肥皂联系，消毒剂接触，消除脂质皮肤，一个是水分流失增加，此外，可以改变皮肤更干燥，由于老年人缺乏皮脂，皮脂分泌减少，皮肤干燥显示，在粗糙的麸皮故障，像过冬天屑来了，天气寒冷，加上热热水澡或多用肥皂，会导致皮肤更糟糕的是，干燥，发痒也比较严重。

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.
