It can make carburized layer on titanium alloys by electrospark deposition, and the carburized depth is about 40～50 μm.

用电火花渗碳技术可在钛合金表面形成一层40～50μm厚的渗碳层，分析显示渗碳层中主要是由石墨电极与基体反应生成的TiC相组成。

Science and Technology, Nanjing 210094, JiangsuAbstract : The carbon gradient of carburized case of parts can be predicted by using the finite difference method.

摘 要：零件渗碳后渗层的碳浓度分布可以用有限差分法预测，而碳浓度的高低决定了工件淬火后的硬度。

The case depth is the most important quality index of carburized materials, and it is usually checked by selective examination. This traditional method is inefficient and low reliability.

渗碳层深度是衡量渗碳质量的主要技术指标之一，传统的渗碳层深度检测方法是对大批产品采取抽样检查，不仅检测效率低，可靠性差，而且检测时需破坏样品。

Choose sensible carbohydrate-rich foods. Carbs don't have to be gooey and chocolatey every time, Wurtman says. She suggests low-fat crackers, for instance, or pretzels. It keeps the fat low but gives you the carbs you want.

对富含碳水化合物的食品要有所选择，碳水化合物并不总是意味着蜜糖和巧克力食品，Wurtman说，她建议选择低脂饼干如椒盐饼干，它含较低的脂肪并且能够满足你对碳水化合物的需求。

The kiln body is divided into two sections of electrical furnace body and dynamic rotation with the kiln body constructed of clayed circular hearth uniformly inserted with 9 silicon carbon rods along the circular axis( one group made up of 3 rods and Y connection for every 3 groups).

窑体部分又分为电炉炉体和动力转动两部分，炉体部分采用粘土质圆形炉膛，沿圆轴向均匀插9根硅碳棒（每三根串联成一组，三组按& Y &接线）高铝质的陶瓷炉管又置于硅碳棒内周，通电后硅碳棒产生高温，加热炉管。

Eating carbohydrates seems to help carb cravers feel better in about 20 minutes, according to Wurtman's research. When you eat carbs, your body makes more serotonin, the feel-good hormone that is boosted when you are on an antidepressant.

根据Wurtman的研究，碳水化合物看起来好像能够帮助碳水化合物渴望这在20分钟内感觉情绪好转，当你吃碳水化合物食品时，你的身体会产生更多的复合胺，当你服用抗抑郁药物时同样身体产生更多的这种愉悦感的激素。

As yet there is lack of information on the effects of elevated CO_2concentration on carbohydrate contents in stem, branch and root of plant, and oncarbohydrate allocation in organs of plant although there have been many reports onthe responses of carbohydrate contents to elevated CO_2 concentration in plant foliages.

迄今为止，有关CO_2浓度升高对植物叶片中的碳水化合物含量的研究较多，而对其它器官中碳水化合物含量以及碳水化合物在植物体内的分配响应研究较少。

Three theories dominate:(1) it is being dissolved in the ocean, and then it precipitates to the sea bottom as carbon rain; or (2) it is being deposited in soils by microbes; or (3), most controversial, the lost carbon is fueling growth of the world's savanna grass, or being turned into tree wood, on an imperceptible but massive scale that we haven't yet been able to measure.

关于失踪的碳的理论有很多，占主导地位的有三个：(1)溶入了海洋，最终作为碳雨沉到洋底；(2)被微生物储存到泥土中；(3)最具争议：失踪的碳悄悄地但规模巨大地促进了世界大草原草的生长，或者变身为树木，而我们还未能对其进行测量。
