有害地

But, under really adverse conditions, human intervention is ineffective, and the control system must be self-correcting and self-optimizing-which means that the system must adapt heuristically to reduce, not increase, the need for operators.

但是，在真正的有害状态条件下，人为的干涉并不起作用，那么控制系统必须自动修正和自动达到最优化。也就是说，系统必须能够启发式地适应减少，而不是增加对操作员的需求。

Be in from the ground in the atmosphere advection layer of 50 kilometers of 15 ～, centered the ozone gas of on the earth 90%, although its chroma never exceeds 1/100000, all concentration rises to also have a even thinner than sole only, but it assimilated opposite substance effectively harmful, wavelengh is less than the UV-C of sun ultraviolet ray of 295nm, and opposite content hurtless, wavelengh is more than the UV-A of sun ultraviolet ray of 320nm to make them all pass however, opposite content has certain harm, wavelengh is in the UV-B of sun ultraviolet ray of 295 ～ 320nm also is absorbed for the most part.

在离地面15～50公里的大气平流层中，集中了地球上90%的臭氧气体，虽然其浓度从未超过十万分之一，全部集中起来也只有比鞋底还要薄的一层，但它却有效地吸收了对生物有害的，波长小于295nm 的太阳紫外线 UV-C，而对生物无害的，波长大于320nm 的太阳紫外线 UV-A 却让它们全部通过，对生物有一定危害，波长在295～320nm 的太阳紫外线 UV-B 大部分也被吸收。

The YAHOOS were the most filthy, noisome, and deformed animals which nature ever produced, so they were the most restive and indocible, mischievous and malicious; they would privately suck the teats of the HOUYHNHNMS' cows, kill and devour their cats, trample down their oats and grass, if they were not continually watched, and commit a thousand other extravagancies.

&雅虎&是大自然所生的一种最肮脏、最有害、最丑恶的动物，因此它们最为倔强而又不可驯服，恶毒而又惹事生非；要不是经常看管着它们，它们就偷偷地去吮食&慧马&养的母牛的奶，杀死并吃掉它们的猫，践踏坏它们种的燕麦和青草；还有许多别的无礼行径。

No significant correlation between the whole numbers of MES and brain malacia was found. Conclusion TCD monitoring of MES during ECMO was successful, and may help to improve the quality of the ECMO operations and to decrease the potentially harmful embolization during ECMO.

TCD可成功地检测到羊ECMO期间的栓子信号，TCD栓子监测对提高体外循环操作和管理水平，减少潜在有害的脑栓塞有指导意义。

Directing at the data distortion caused by the fault of sensors, and considering the factors influencing the measurement of certain exhaust gas in an animal barn such as temporal, spatial and environmental parameters, neural network is introduced to data fusion so as to figure out the missed data due to the faults of this sensor measuring the value of this exhaust gas. By this method, total emission of nocuous gases from the barn is measured accurately, and the emission of exhaust gases beyond normal standard was controlled.

针对因传感器故障而失真的数据，综合考虑对畜禽场排放的某一废气测量值的时间、空间和环境等多种影响因素，使用基于神经网络的数据融合方法来估算该废气的浓度，实现失真数据的恢复，从而精确地测量出养殖场连续排放的有害气体的总量，对超标排放进行监控。

The high-speed X-Ray tester ED-11 is institute of X-Ray Technologies Co., LTD aimed at RoHS restriction to excogitate that one high quality tester, and it is for China Electronic C of C request that according Chinese user can easy and fast to test. Our company is selling agent of ED-11 in China market.ED-11 is adopt X-Ray of W pole and Supper SDD technology that can test nocuous elements of (Cd/Pb/Cr/Br/Hg) within 100 second with highly sensitive speed.

我司代理销售的高速荧光X线测试仪ED-11是应中国电子商会的要求，以中国国内用户可以简单，迅速地进行RoHS检查为目的的装置，也是日本株式会社X线技术研究所针对ROHS指令所研发的一款高尖端测试仪，ED-11通过采用W电极的X射线管与Super SDD技术，能够以高灵敏度在100秒同时检测ROHS规定的有害元素(Cd/Pb/Cr/Br/Hg)的精确含量。

It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

In Park-street Church, on the Fourth of July, 1829, in an address on slavery, I unreflectingly assented to the popular but pernicious doctrine of gradual abolition.

当时我欠考虑地说我同意那种流行的但又是有害的关於逐渐废除奴隶制的观点。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
