The 72h · EC50 of Chaetoceros muelleri and Phaeodactylum tricornutum Bo blin were 346mg/L and 445mg L-1, respectively.

其中只有角毛藻和三角褐指藻在实验范围内(0~5 00mg/L)测到了72h的半抑制浓度，EC50分别为346mg/L和445mg/L。

The approach to calculating the gliding angle and flight time of each segment was given.The procedure for approaching the whole glide trajectory was described.Two examples show that the differences in the gliding range and flight time between the approximate solution and the...

文中算例结果表明，该近似求解方法计算得到的滑翔航程和滑翔时间与实际值相差很小，航程误差率约为0.7%，时间误差率约为0.6%，因此该方法在近似小初始滑翔角的长航时远程纵向滑翔飞行时是有效的、可行的，尤其针对航程在地球半圈以上的滑翔飞行轨迹。

The conclusion is drawn from the simulations that the secondary electrons will go out from the sample surface more easily with the decrease of the half cone angle of tip and the increase of secondary electron energy, tip-sample separation and the distance of the emission site away from the point directly under the tip.

模拟的结果发现针尖半锥角越小、次级电子能量越高、针尖样品间距越大、次级电子出射位置离针尖正下方越远则越有利于次级电子的逸出，此外通过栅网与一个平行于样品表面的地电极的共同作用，会对次级电子产生聚焦作用。

The effects of structural parameters of liner and initiation methods on projectile formation and performance parameters were shown by simulation, the interrelations of structural parameters of liner were preliminarily fixed on, the inner radius of liner R1=(0.55-0.6)D, outer radius R2=(0.58-0.62)D, height H=(0.3-0.35)D, half cone angle α=82°-86°, where D is diameter of liner.

通过模拟计算得到了药型罩结构参数和起爆方式对弹丸成型的影响规律，并初步确定药型罩结构参数间的相互关系：药型罩直径D，内径R1=(0.55~0.6)D，外径R2=(0.58~0.62)D，药型罩高度为H=(0.3~0.35)D，半锥角α=82°~86°。

The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.

天然富勒烯研究是富勒烯科学和地质科学相交叉的一个新兴研究领域，迄今为止已在桑加岩、闪电熔岩、陨石撞击坑中的含碳质角砾岩、古近系/白垩系地层界线的含碳粘土岩、三叠系/二叠系界线岩石、恐龙蛋壳、煤、重质油、固体沥青以及半天然的烟灰、木炭、书墨等物质中检测到富勒烯的存在，但含量很低。
