查询词典 at a cost

The uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.

The latest chemical product prices fell, demand has not really visible downstream, the short-term rise in oil prices in the channel, in which phase fluctuations, we continue to be optimistic about with anti-cyclical businesses and new materials, anti-cyclical embodies New Chemical Materials decrease in prices of raw materials is less than the decrease in prices of raw materials at the same time, the cost shift ability, to maintain price stability; civil explosive materials companies fell as a result, prices, countries can enjoy the benefits of; domestic urea production capacity excess of export disruption, high product costs, industry consolidation is inevitable, so concerned about the urea industry with technical advantages and cost advantages of urea enterprises: China Shandong Hengsheng; Although the overall situation of excess nitrogen, but because of the regional characteristics of the domestic fertilizer domestic part of the region will be in a high urea prices, the relevant listed companies will benefit from, such as the Liao Tung Chemical; compound assets as light industry, with the weak cyclical characteristics, the stability of industry profitability, industry leaders concerned about the compound: para Tian shares ; potash by the international market, short-term decline of domestic potash fertilizer prices would have difficulty, Salt Lake Potash in 2009 will be guaranteed a profit, Salt Lake Potash concern.

最新化工产品价格出现下跌，可见下游需求并未真正起来，短期石油价格处在上升通道，在这种上下波动阶段，我们继续看好具有抗周期性的新材料企业，抗周期性体现了化工新材料的产品价格下降幅度小于原料的下降幅度，在原料价格上涨同时，成本转嫁能力较强，价格维持稳定；民爆企业由于原料下跌，价格上涨，可以享受国家指导价的益处；由于国内尿素产能过剩，出口受阻，产品成本居高不下，行业整合在所难免，因而关注尿素行业内具有技术优势和成本优势的尿素企业：华鲁恒升；虽然氮肥全局过剩，但由于国内化肥的区域性特征，国内部分区域尿素价格将处于高位，相关上市公司将因此受益，如辽通化工；复混肥作为轻资产行业，具有弱周期性特点，行业盈利稳定，关注复混肥行业龙头：芭田股份；钾肥受制于国际市场，短期内国内钾肥价格恐难下跌，09年盐湖钾肥盈利将会有保证，关注盐湖钾肥。

No doubt many tramps would drink if they got the chance, but in the nature of things they cannot get the chance. At this moment a pale watery stuff called beer is sevenpence a pint in England. To be drunk on it would cost at least half a crown, and a man who can command half a crown at all often is not a tramp.

无疑有许多流浪汉有机会就要喝酒，然而现在，那种叫做啤酒的颜色苍白、味道像水的玩意儿在英国卖六便士一品脱，要想喝醉，至少得花半克朗，但是真的有那么半克朗可以支配的人常常不是流浪汉。

Terms such as rational maximizer, marginal cost, and demand curve fall neatly into place within the real-life example of padding over to one's thermostat on a cold winter's morning to decide where to set it, gauging where the cost benefit tradeoffs might be-a process very similar to the one being performed at the other end of this transaction, by the marketplace players that provide our heating fuel.

诸如理性maximizer ，边际成本，需求曲线过于片面发生了现实生活中的例子，填充到一个人的调温器对寒冷的冬天的早晨，以决定在何处设置，以评估那里的成本效益权衡可能-一个过程非常相似，一个正在演出的另一端，这宗交易中，市场参与者提供取暖用燃料。

Xu Anbin: The conference with the more immediate impact of economic crisis is our IDC operation business, when individual stationmaster goes looking for IDC operation business to buy a server, when been compare a little according to the economy previously, a server gives IDC operation business head of a station, buy a server, oneself throw a server, hire our stationmaster by the month, our stationmaster presses this moment it is good that the month pays fee, nodical cash pledge, but economic crisis came, everybody does not have money, when this time head of a station looks for them to hire a server again, pay them by the month already not quite actual, the hire that we discover a server now is according to the quarter, year hiring, not according to will pay by the month, the cost of this moment operation can rise, the income of individual stationmaster actually not tall also, I am in 98 years when myself does individual website, we are the free spaces that put a tradition at that time, to 2000 when I just have a server, the doorsill that I see operation cost now can be higher threshold to them.

许广彬：经济危机的影响更直接的会是我们的IDC运营商，个人站长去找IDC运营商购买服务器的时候，按照以前的经济稍微比较好的时候，IDC运营商一台服务器给站长，买一台服务器，自己投入服务器，按月租给我们的站长，这个时候我们的站长按月付费就好了，交点押金，但是经济危机来了，大家都没有钱，这个时候站长再找他们租服务器的时候，按月付给他们已经不太现实了，现在我们发现服务器的租用都是按照季度，年在租，没有按照按月来付，这个时候运营的成本就会提高，个人站长的收入其实也不高，我在98年的时候我自己做个人网站，那个时候我们都是放传统的免费空间，到2000年的时候我才拥有一台服务器，现在我看运营成本的门槛对他们会是比较高的门槛。

Xia Zujun is stared at then went up traditional supermarket, what this he faces is complex supermarket regulation, should pay cost entering the arena, bar code fee, on ark is expended (the place with good make choice of), inn celebrates all sorts of charge such as cost, xia Zujun is handed in do not have afore-mentioned cost, cannot get used to a supermarket live regular.

夏祖军接着盯上了传统超市，这次他面对的是复杂的超市规则，要交进场费、条码费、上柜费、店庆费等各种费用，夏祖军交不起上述费用，不能适应超市的生存规则。

I have been in all my Circumstances a Memento to those who are touch'd with the general Plague of Mankind, whence, for ought I know, one half of their Miseries flow; I mean, that of not being satisfy'd with the Station wherein God and Nature has plac'd them; for not to look back upon my primitive Condition, and the excellent Advice of my Father, the Opposition to which, was, as I may call it, my ORIGINAL SIN; my subsequent Mistakes of the same kind had been the Means of my coming into this miserable Condition; for had that Providence, which so happily had seated me at the Brasils, as a Planter, bless'd me with confin'd Desires, and I could have been contented to have gone on gradually, I might have been by this Time; I mean, in the Time of my being in this Island, one of the most considerable Planters in the Brasils, nay, I am perswaded, that by the Improvements I had made, in that little Time I liv'd there, and the Encrease I should probably have made, if I had stay'd, I might have been worth an hundred thousand Moydors; and what Business had I to leave a settled Fortune, a well stock'd Plantation, improving and encreasing, to turn Supra-Cargo to Guinea, to fetch Negroes; when Patience and Time would have so encreas'd our Stock at Home, that we could have bought them at our own Door, from those whose Business it was to fetch them; and though it had cost us something more, yet the Difference of that Price was by no Means worth saving, at so great a Hazard.

一般人往往有一种通病，那就是不知足，老是不满于上帝和大自然对他们的安排。现在我认识到，他们的种种苦难，至少有一半是由于不知足这种毛病造成的。患有这种病的人大可以从我的一生经历中得到教训。就拿我自己来说吧，正是由于我不满自己原来的境况，又不听父亲的忠告--我认为，我有悖教训，实为我的&原罪&，再加上我后来又犯了同样的错误，才使自己落到今天这样悲惨的地步。当时，造物主已安排我在巴西做了种植园主。如果我自己不痴心妄想发财，而是满足于逐渐致富，这时候我也许已成了巴西数一数二的种植园主了，而现在我却白白地在这荒岛上流落了这么多年，过着悲惨孤寂的生活。而且，我在巴西经营时间不长；就是在这段短短的时间里，我也获利不少。因此我确信，要是我继续经营下去的话，到现在一定拥有十几万葡萄牙金币的家财了。当时，我的种植园已走上了轨道，并且日益兴旺。可是，我偏偏把这一切丢弃，甘愿去当一名船上的管货员，只是为了到几内亚去贩卖黑奴。现在想来，我为什么要这样做呢？要是我守住家业，只要有耐心，经过一段时间之后，同样可以积聚大笔财富，我不是也可以在自己的家门口，从那些黑奴贩子手里买到黑奴吗？虽说价钱贵一点，但这点差价绝不值得自己去冒这样大的风险！

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
