使必需

As I rifled through the fridge in search of the requisite condiments, I thought about what makes hard-cooked eggs mixed with mayonnaise devilish.

我一边从冰箱里搜寻一些必需的调味品，一边想哪种可以使煮过的鸡蛋与蛋黄酱完美的融合。

From these core talents, some are optional such as: 2/2 Arctic Reach is for mobility; 3/3 Elemental Precision might not be necessary depending on your gear; 1/1 Ice Barrier is for survival; 1/3 Frostbite makes Blizzard proc Fingers of Frost.

在这些核心天赋里，一些是可选的：2/2奥术精妙3/3元素精准或许因为你的装备而不是必需的。1/1寒冰护体是为了生存。1/3寒冷刺骨使暴风雪触发寒冰指。

Exception: A receptacle or cord connector is not required to be of a grounding type when the circuit supplying the receptacle or cord connector is rated 150 volts DC or less and the product is marked as specified in 56.2 to indicate that the product is intended for use only in motion picture and television studios and similar locations.

舞台灯标准 19.5 所有插座或接线端子必需是接地类型除外：电路额定电压低于或等于150V DC，插座或接线端子不需接地线。产品仅在电影或摄影场等类似场使用时必须加以标识，详见条款56.2规定。

It can convert arginine, a semi-necessary amino acid, into citrulline and ammonia. And the absence of arginine can restrain the growth of cell.

精氨酸脱亚氨基酶可把非必需氨基酸——精氨酸转变为瓜氨酸，而精氨酸的缺失将使细胞生长受到抑制。

Imagine you have to balance yourself on a slope, holding skis and poles, while walking downhills.坐著溜下ㄑ would be more dangerous because it might be faster but the skier may lose control when going downhill. Some slopes are very steep and one slip may cause the skier to glide for a long distance.

想像你在走下坡时，抱著滑雪板和滑雪杆，而必需在滑雪坡上保持平衡，坐著溜下ㄑ会更危险，因为那或许更快，但会使其丧失控制能力，有些滑雪坡很陡，只要一失足，滑雪者就会跌落很长的距离。

Containing,fatty oil and special lubricity fortifiers to impart the quick chip releasing property even under extreme high cutting pressure.

铁金属的轻度切削及非铁金属重负荷切削而配制，含有特殊润滑添加剂，就算在高切削压力下，也能使屑片容易于刀具分离，低粘度确保了足够的冷却及冲屑性能，是高速切削所必需。

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是一款专为非铁金属而配制的切削油，适用於铜金属、铝金属及其合金的重负荷切削，含有氯化物、脂肪及特殊润滑添加剂，增进其极压及润滑性能，就算在高切削压力下，也能使屑片容易与刀具分离，低的黏度确保了足够的冷却及冲屑性能，都是高速切削所必需。

NF 77 is a light duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 77 contains special lubricity fortifiers to impart quick release of chip from tool. The low viscosity ensures the good cooling and flushing properties, which are essential for high speed machining.

NF 77 是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的一般輕度切削，含有特殊潤滑添加劑，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。
