太阳光

They can be used to provide up to several megawatts of electric power.

总之，把赐予地球的无限能源-太阳光直接变为电能，是人类的一个美好理想。

The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight. The degradation rates of the above three dyes by ZnM2O4(M=Cr, Mn, Fe) are over 80％, 57％ and 39％, respectively within 2 h. It is found that ZnM2O4 (M=Cr, Mn, Fe)has a novel photocatalytic behavior for dyes under visible light irradiation.

在高压汞灯(λ＞400 nm)和太阳光照射下，纳米ZnM2O4粉体对甲基橙、酸性红B、活性艳红K-2G等有机模拟降解液的2h脱色降解率分别达到80﹪，57﹪和39﹪以上，表明锌尖晶石ZnM2O4光催化剂具有良好的可见光催化活性，并随禁带宽度Eg的减小，催化活性增加。

C. Full sunlight on a cloudless day during midsummer supplies an illuminance of between 12,000 ft. c. and 15,000 ft.

烛光(在仲夏无云的白天，最充分的太阳光提供在12000和15000ft.c之间的照明度)。

Perovskite oxides (ABO3) has stable structure and high photocatalytic activity ,further morea catalyst which has more narrow band gap can be synthesized and can absorb more solar energy by altering the type of A and B.

钙钛矿型氧化物(ABO_3)不但具有结构稳定，催化活性高等特点，而且可以通过改变A、B原子的类型制备出禁带宽度较窄，能大量吸收太阳光的催化剂。

Nacreous clouds form when the fading light at sunset passes through tiny ice crystals blown along by a strong jet of stratospheric air.

珍珠云是由于日出时的太阳光穿过被一股强气流吹起的冰晶体时形成的。

The sun's rays, shining through the oculus on the south wall, moved farther down the line every day, indicating the passage of time, from solstice to solstice.

每天，太阳光通过南墙上的洞眼照射进来，光束会顺铜线上的刻度一点一点地移动，这样就可以计量时间了。

For an active corona, a system consisting of the electromagnetic field and particles, the only open surface is the solar photosphere.

活动日冕，作为由电磁场和粒子组成的系统，其唯一的开场表面是太阳光球。

Snowblind also known as ophthalmia sunlight.

雪盲亦称太阳光眼炎。

The natural satellite of Earth, visible by reflection of sunlight and having a slightly elliptical orbit, approximately 356,000 kilometers (221,600 miles) distant at perigee and 406,997 kilometers (252,950 miles) at apogee.

月亮，月球：地球的天然卫星，通过反射太阳光而发光，并有一个略呈椭圆形的轨道，在近地点时，距离约有356，000公里221，600英里），在远地点距离约有406，997公里(252，950英里）。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
