查询词典 km

Great differences between them are found in amplitude, and attributed to the strong background wind in troposphere and steady weak wind in lower stratosphere. Steady diurnal variation of temperature appears above 23 km, and the same variation in pressure is found starting from lower altitude, which together suggest a weak diurnal variation in atmosphere density above 23 km, that approximates a constant at each height.

发现风场振幅的变化与统计平均的结果存在较大差异，这归结于当地冬季对流层内强烈变化而低平流层内相对稳定的风场；温度在23 km以上存在稳定的周日变化，气压在更大的范围内存在与温度类似的周日变化，这使得在23 km以上大气密度的周日变化十分微弱，在各个高度上近似为一个常数。

The atmospheric transmittance database for l064nm laser is created basing on the FASCODE. The model atmosphere is midlatitude summer. The slant path length covers (0~10) km with the alternation of 0.1km. The elevation covers 0°~91° with the alternation of 5° The surface range covers (5~20) km with the alternation of 1km.

In 2002, I went to the north rim of the Grand Canyon and drove on a dirt road for 180+KM. Yes, 180+KM in a Mitsubishi Montero 4WD.

在2002年，我到大峡谷北部边缘地方，开车在泥土路上超过180公里，没错， 180公里开的车就是Mitsubishi Montero 4WD。

There are two entrances to the park; the more-developed south rim entrance is located 15 miles (24 km) east of Montrose , while the north rim entrance is located 11 miles (18 km) south of Crawford and is closed in the winter.

黑峡谷名称的由来是由于峡谷的窄与深使得一天里绝大多数时间太阳只能照到峡谷很小的一部分，所以岩石看上去总是黑黑的。

Km from Guangzhou, Foshan, 26 kilometers, 127 kilometers (69 nautical miles), Macao 80 km.

距广州32公里、佛山26公里、香港127公里(69海里)、澳门80公里。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。

A carrier gas such as nitrogen is directed through line 20 and valve 22 to connect with line 26 and mix with the gas sample.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。
