That it was affirmed that the great Hendrick Hudson, the first discoverer of the river and country, kept a kind of vigil there every twenty years, with his crew of the Half-moon; being permitted in this way to revisit the scenes of his enterprise, and keep a guardian eye upon the river, and the great city called by his name.

这是肯定，伟大的亨德里克赫德森河的第一个发现者和国家，保持了一种存在的守夜每20年来，他对船员半文，被人以这种方式来重温他的企业允许的场景，并保持河流经监护人的眼睛，和伟大的城市以他的名字叫。

2Graduate School of Chinese Academy of Sciences, Beijing 100049, ChinaAbstract: Two sets of dehydrationmelting with a natural solid amphibolite(56vol.% hornblende, 43vol.% plagioclase), collected from the DabainengLeyu profile in the southern Ailaoshan orogenic belt, Honghe County, Yunnan Province, have been carried out in multianvil apparatus(YJ3000t and JL3600t) at 1035 GPa and 950 ℃ for 20300 h. One is keeping the temperature at 950 ℃ and the annealing time of 100 h, varying the pressure (1035 GPa). The other is keeping the pressure at 30 GPa and temperature at 950 ℃, varying the annealing time (20300 h). The products are inspected with microscope and electron probe.

利用YJ3000t和JL3600t多顶砧压力机，以哀牢山造山带南部红河县大白能-乐育剖面上的天然块状斜长角闪岩为初始样品，在950 ℃、10~35 GPa、恒温20~300 h条件下进行了两个系列的斜长角闪岩块状样品脱水部分熔融实验：(1)保持温度T=950 ℃，加热时间t=100 h不变，改变压力(10~35 GPa)的实验；(2)保持温度T=950 ℃，压力p=30 GPa不变，改变加热时间(20~300 h)的实验。

They will keep the hosting of the database, and we want to keep it in our control.

他们将保持数据库的存取，我们要保持我们的控制。

Mathematic proof of the hypertonicity for this model is given using two different cases. Furthermore, the Riemann invariants for the multi-class traffic flow LWR model are studied by using characteristic line method, and the physical interpret of the Riemann invariants are also pointed out. The information in transfer is obtained, that is, the total density and the relative density hold the same.

用两种方法给出了该模型在不同情形下双曲性的数学证明，运用特征线方法研究并计算了任意等级MCLWR交通流模型的Riemann不变量，得到了其传递的交通信息，给出了Riemann不变量物理意义的解释，即总密度保持不变和相对密度保持不变，最后又从形式上指出了在多等级车流并行时，MCLWR与LWR两种交通流模型实际上是等价的。

At valve repair, import relief valve repair complex; import relief valve, control valves are used the body parts of the opening gate to regulate the flow of medium, medium pressure to lower pressure after the valve simultaneously with the role of regulation headstock of the opening piece, so that after the pressure valve to maintain at a certain range, the inlet pressure at the ever-changing circumstances, to maintain outlet pressure at setting the framework of the back to protect its pipelines, equipment, pressure, temperature stability ..................

在阀门维修中进口减压阀维修比较复杂；进口减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后面管道、设备的压力、温度的稳定
