查询词典 lead-in

The polyvinyl chloride static and dynamic experiments of the heat stability by three novel low-lead, non-lead and low-tin, and non-lead and non-tin thermal stabilizers remixed respectively with phosphite ester, epoxidized soybean oil,β-diketone, pentaerythritol and houghite were reviewed.

通过新型低铅、无铅低锡和无铅无锡热稳定剂分别与亚磷酸酯、环氧大豆油、β-二酮、季戊四醇和水滑石进行复配，进行了聚氯乙烯的静态和动态热稳定性实验。

However, as well known, during traditional fire metallurgy of lead and production of lead/acid battery, there are emissions of lead vapor, sulfur dioxide and leady dust, which is harmful to the health of operators and brings about atmosphere pollution.

因此，应该研究和实现铅酸蓄电池的清洁生产。

VRLA battery uses lead calcium alloy for grid and lead tin alloy for strap, the COS process more likes soldering, COS of lead-tin strap is difficult and needs flux and tinning.

VRLA电池使用铅钙合金板栅和铅锡合金汇流排，其制造过程更像是钎焊。铅锡合金汇流排铸焊过程须使用助焊剂和搪锡。

Lead 1、soft blue-gray mineral; lead sulfide; a major source of lead

一种软质的兰灰色矿物；硫化铅，铅的主要来源

Chinese E moves net and PHPwind strong strong combination, roll out lead plane of PHPwind super forum, MYSQL column is found after the user of use PHPwind lead plane should enter fictitious lead plane to manage only, add a Mysql database that belongs to oneself, use directly already analytic good domain name visit, can receive the installation page of PHPwind.

中国E动网和PHPwind强强联合，推出PHPwind超级论坛主机，使用PHPwind主机的用户只要进入虚拟主机管理后找到MYSQL栏目，添加一个属于自己的mysql数据库，直接用已经解析好了的域名访问，即可得到PHPwind的安装页面。

Using this method, alignment between headstock and tailstock centers is not able to be adjusted, and is far from what would be considered "close tolerances." All leadscrews have 1/4-20 threads, with the cross slide and main lead screws being the appropriate left-hand lead, while the tailstock is a right-hand lead, so turning the handwheel always advances the slide away from the user.

使用这种方法，路线之间的 headstock和尾架中心，是无法加以调整，是远远没有到会被认为是&密切公差&的所有leadscrews有1/4-20线程，与两岸幻灯片和主要领导螺丝被适当的左莅带头作用，而尾架是一个右手边的铅，因此，把手始终进展幻灯片远离用户。

The; of down-lead of 200 A binary electric current that the design made intensity of central field magnetic induction be 3 T is opposite through the experiment of the thermal resistance of interior of the leakage heat of voltaic down-lead, heat exchanger and line of high temperature superconduction and cupreous matrix solder resistor undertook metrical, studied refrigeration engine trouble or the transient state temperature of down-lead of the electric current below power cut condition changes.

设计制作了中心场磁感应强度为3 T的200 A二元电流引线；通过实验对电流引线的漏热、换热器内部的热阻以及高温超导线和铜基体的焊接电阻进行了测量，并探究了制冷机故障或者停电状态下电流引线的瞬态温度变化。

When the concentration of lead was very high, the most of lead linked weekly with the cell wall of root and was easy to dissolve into acidic solution. But about 50μg Pb/g cell wall was very hardly desorbed, it might be entered into the cell wall. This phenomena showed that the complete desorption of lead will be very difficult.

铅浓度高的细胞壁，其相当大部分的铅与细胞壁的结合力并不大，因此在用强酸处理时，就比较容易地溶解下来，但是大概有50微克／克细胞壁的铅，它们的结合牢度大，或者深入到了细胞壁的组织中，因此很难解吸下来，这将会对铅的彻底去除带来困难。

The main technological innovation is as follows: Adopting collector Bp was of high-effect to float copper; using no-toxic and combinatorial depressants to depress lead, the experiment was carried out effectively for separation of copper-lead; Adopting processing of copper middle to concentrate a cyclone classificating and a mill regrinding, it solved the vicious cycle of the lead and was of low dissociation.

其主要技术创新点有：采用高效捕收剂BP实现铜铅优先浮选；采用高效无毒组合抑制剂实现铜铅的有效分离；采用铜中矿集中旋流器分级再磨处理解决了铅的恶性循环和单体解离度低，有效地解决了铜铅分离的技术难题。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
