In this bath, maleic acid was an inhibitor, when its concentration was kept at 20 mg/L, the deposition rate could reduce to 6.17μm/h, the content of nickel decreased to 1.74% and the resistivity was 7.51μΩ·cm; Potassium ferrocyanide inhibited deposition of copper, when its content was 0.5 ppm, the deposition rate decrease to 3.38μm/h, the content of nickel was 2.03%, the resistivity can reduced to 5.41μΩ·cm, the copper deposits also had higher (111) plane orientation. Thiourea was also an inhibitor in this system, when its concentration was kept at 0.8 ppm, the deposition rate was 4.72μm/h, the content of nickel in the film was 1.20%, the resistivity can reduced to 5.46μΩ·cm, at the same time, the deposition at (111) plane orientation become more favorable.

结果表明，马来酸在该体系中是抑制剂，当其浓度为20 mg/L时，镀速降为6.17μm/h，镀层镍含量降为1.74%，表面电阻率降为7.51μΩ·cm，铜层颗粒细小均匀，更有利于在(111)面上的结晶；亚铁氰化钾的加进可以明显降低镀，当其浓度为0.5 ppm时，镀速为3.38μm/h，镀层镍含量降为2.03%，表面电阻率降为5.41μΩ·cm，铜层颗粒细小均匀，(111)晶面衍射峰增强；硫脲在体系中也显示为抑制剂，当其浓度为0.8 ppm时，镀速降到4.72μm/h，镀层镍含量为1.20%，表面电阻率降为5.46μΩ·cm，形成的铜颗粒很小，同时(111)晶面衍射峰增强，有利于铜在(111)面上结晶。

When the TN:TP ratio was 25:1,V.spiralis had the best growth, with a biomass increment being 54% and 31% higher than that when the TN: TP ratio was 12.5:1 and 50:1, respectively, while the growth of periphyton, especially of epiphytic algae, was the worst, giving the least adverse effects on V. spiralis, indicating that a 25:1 of TN:TP ratio in eutrophic water was optimal for the growth of V. spiralis. However, such an optimal TN: TP ratio only worked when the nutrients concentration in eutrophic water was below the limited level, otherwise, it could be failed to be applicable.

结果表明：当TN/TP为25：1时，苦草的生长状态最好，苦草生物量的增长率最大，分别高于TN/TP为12.5：1和50：1时的54%和31%；当TN/TP为25：1时，附着生物尤其是附着藻类的生长状态最差，对苦草生长的不利影响最小；可见，富营养水体中适宜于苦草生长的TN/TP为25：1；TN/TP为25：1这一比例的应用具有相对性，当水体营养浓度低于限制水平时，该比例适用，如果水体中营养盐浓度超过限制水平时，该比例则不适用。

Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragm the effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric air compressors idling.

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的用途力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压用途下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。

The error of a surface on the electrical potential distribution can be neglected when the order of the distance which from center to the surface we assume the potential decay to zero about 102 of its radius. This effect also can be neglected when the potential is high, but it can be taken into account by multiplying a correction function to the potential of surface when the surface potential is low.

并且当表面电位较高的时候，近似解析解对於空间电位的分布会有较好的描述，即和数值解的结果会有较少的误差；而在表面电位较低的情况下，圆柱座标以及球座标的近似解可以乘上一个校正函数来修正，则可以有效的大幅降低误差，更可以正确的描述胶体粒子内部的空间电位分布。

The result showed that LPS inhibited the proliferation of pulp cells when its concentration was 100μg /ml; it could induce the apotosis of the cell when in 250μg /ml and it could lead the pulp cell to die when in 450 μg/ml.

g／ml浓度的LPS可抑制细胞生长，使细胞体积缩小；200μg／ml浓度的LPS可使个别细胞收缩变圆，发生类似凋亡样改变；而400μg／ml浓度的LPS可使细胞肿大、破碎发生坏死样改变。

He does not weep. He waits longingly for a particular day he remembers in the future when he and his friend will have sandwiches on a low flat table, when he will describe his fear of growing old and unloved and his friend will nod gently, when the rain will slide down the glass of the window.

他不悲伤。他盼着将来有那么一天，他将回忆起和朋友在小矮桌上吃三明治，诉说对老来无人爱的恐惧，朋友轻轻颔首，雨水流满窗。

V2. When the swallows have gone, there is still time to return; when the poplar and willow trees have become withered, there is still time to see green; when the peach flowers have already faded, there is still time to blossom.

一般现在时表示恒常的事实(时间的匆匆流逝是不以人的意志为转移的，是浑然一体的，并暗示了读者要珍惜宝贵的时间)三个独立的句子结构上不够紧凑，层次感不强
