查询词典 pitch-black

Tantalum-containing pitch as a carbon precursor was synthesized by an in situ liquid phase reaction between coal tar pitch and tantalum pentachloride.

以煤沥青为原料，氯化钽为钽源，通过化学反应制备了含钽沥青前驱体。

Also, the effects of the amount of tantalum pentachloride and reaction time on the softening point of the pitch were investigated. Results showed that the tantalum particles were dispersed homogeneously in the pitch precursor with sizes in the range of 20-50nm. The tantalum particles mainly existed in the form of δ-Ta2O5 when the reaction temperature was 420℃. By further heat treatment,δ-Ta2O5 was transformed into β-Ta2O5 at 900℃.Β-Ta2O5 and TaC co-existed at 1200℃. At 2800℃, all the tantalum was transformed into TaC.

结果表明：沥青中钽化合物的粒度为20nm～50nm，主要以五氧化二钽的形式均匀分散于沥青中；惰性气氛下，较低温度(420℃)热处理时，钽化合物以δ-Ta2O5的形式存在，温度升高到900℃时，δ-Ta2O5转化为β-Ta2O5，在温度达到1200℃时，β-Ta2O5和碳化钽共同存在于炭基体中，在2800℃温度下，钽完全转化为碳化钽。

Jorge Posada hit a leadoff single, reaching third when centerfielder Torii Hunter let it get past him, and scored on Silva's wild pitch. Matsui doubled and scored on a single by Abreu, who was safe when shortstop Jason Bartlett failed to hold the throw on an attempted steal. One out later, Cano was hit by a pitch by Juan Rincon. After the runners moved up on Damon's comebacker, Cabrera singled to drive in both. He took second on the throw to the plate and scored the fifth run of the inning on the second of Jeter's three hits.

Jorge Posada率先击出安打，并且因为中外野手Torii Hunter 让球滚到身后而登上三垒，再趁Silva的暴投得分，松井击出二垒安打后靠著Abreu的一垒安打得分，Abreu则因游击手Jason Bartlett无法接住传来的球而盗上二垒，在一人出局之后，Cano被Juan Rincon的触身球打上一垒，两位跑者靠著Damon打回给投手的滚地球推进之后，Cabrera击出一垒安打把他们都送了回来，并趁球传回本垒时上到二垒，最后靠Jeter三支安打中的第二支得到该局的第五分。

We did pitches 8 and 9 slightly different from the guide book. Wes climbed through the Dolt Hole and belayed at the top of the bolt ladder. I lowered off, pendulumed into the stove leg cracks and climbed through the 8th pitch belay and finally belayed at the finish of the 9th pitch. It was a full 165', but it made it much better for the haul bag (it didn't have to pendulum so far) and we didn't have to belay on the cramped 8th stance (although the 9th belay was barely a stance as well).

我们在第八九绳距跟guidebook有些不同，Wes爬过Dolt Hole然后在bolt梯的顶部确保，我降下去，摆荡到Stove Ledge裂隙，爬上第八绳距确保处到第九绳距的确保处，全部一百六十五英呎，但如此对於拖拉包比较简单，且我们不用在狭窄的第八绳距站著确保（虽然第九绳距确保处也不大）。

As the season trudges along, every fifth day we forget all about Hughes' and Kennedy's troubles and watch a potential milestone season unravel for Wang. We hold our breath with every pitch thrown hoping that the problematic fingernail does not flare up and impede on his march to October. Last night you could hear the gasps from the raucous crowd when in the fifth inning, Wang summoned Jose Molina to the mound after a pitch and was seen flicking his right thumb. Manager Joe Girardi and Head Trainer Gene Monahan immediately jogged to the mound, hoping their worst fears were not realized. At that point you could immediately feel the sense of urgency in the organization. This was their gem, their only bridge between now and championship number 27. 9 M# u7 Y s# W O
