通过对辉绿岩的高温高压交代实验及理论计算,研究了洋中脊的热液交代过程。这一交代过程的存在可以从洋中脊的热液化学组成、挖掘到的变质玄武岩样品的化学、矿物学以及陆地上的蛇绿岩露头得到证实。所获结果表明,Mg、Ca、Na的固定反应分别发生在不同的交代条件下。Mg的固定反应发生在海底热液对流圈的下降翼,Ca、Na的固定主要和上升翼有关,其中Ca反应发生于深部,Na反应则位于上升翼近于海底的部位。热液中Ca的迁出,伴随着h^+的产生。减压过程大大地增进了这一反应。和其他含钙交代相相比,绿帘石的稳定性也因此而提高。在热液体系中,绿帘石和斜长石这两个固溶体制约着热液的化学成分和ph值。东太平洋隆起21°N黑烟囱中喷出的热液来自于385—400℃、300—400bar的反应带。只要弄清了盐度的影响、由传导冷却而造成的退变质过程以及混合过程,就可确定所有热液的反应带的温压条件。

AIM: To evaluate the light adjustable lens(LAL) vs a standard monofocal lens in achieving target astigmatic refraction and improving postoperative uncorrected distance visual acuity(UDVA). METhODS: This randomized controlled clinical trial included 40 patients with pre-existing astigmatism and visually significant cataract. Twenty-eight patients received the LAL and 12 control patients received a monofocal intraocular lens(IOL) after cataract extraction at a single institution. The patients with the LAL underwent adjustment by ultraviolet(UV) light postoperatively plus subsequent lock-in procedures and all patients returned to clinic for follow up of study parameters at 6, 9, and 12 mo. Manifest refraction, distance visual acuity, and adverse events were recorded at each ***: The mean cylinder before adjustment in eyes with the LAL was-0.89±0.58 D(-2.00 to 0.00 D) and-0.34±0.34 D(-1.25 to 0.00 D) after lock-in(P=1.68 x10-8). The mean cylinder in patients with the monofocal lens was-1.00±0.32 D(-1.50 to-0.50 D) at 17-21 d postoperatively, which was statistically different from the LAL cylinder postlock-in(P=1.43 x10-6). UDVA in the LAL group was 20/20 or better in 79% of patients post lock-in with good stability over 12 mo compared with 33% of the control patients with UDVA of 20/20 or better. CONCLUSION: These results demonstrate that the LAL is more effective in achieving target refractions and improving postoperative UDVA in patients with pre-existing corneal astigmatism than a standard monofocal lens.

新植火炬松对于种植时施用氮肥通常没有反应,部分原因是施肥处理往往增加了杂草与林木的竞争。不过,通过施肥有使松树加速占领林地,减少阔叶树的竞争,以及缩短轮伐期等的可能性,所以此种处理仍能引起很大兴趣。通过施用氮肥促进新植火炬松生长的关键是抑制杂草。植物之间的竞争引起新植松树水分紧张。因此,有必要进行在种植时使用除草剂与氮肥相结合的试验。

Corn (maize, Zea mays L.) hybrids expressing the flexibility trait in ear size (number of kernels per ear) are marketed for ability to give higher yields under adverse conditions. Altered kernel number is associated with altered number of silk, a major route for infection of kernels by aflatoxin-producing fungi such as Aspergillus flavus. The effect of plant density and irrigation level on yield and accumulation of aflatoxins and fumonisins in harvested grain was compared in a fixed-ear hybrid (Pioneer 33K81), a semi-flexible ear hybrid (Pioneer 3223) and a flexible ear hybrid (Golden Acres 8460) over a range of seeding densities (49,400, 61,750, 74,700, 86,450, and 98,800 seeds·ha–1) in non-irrigated, moderately-irrigated (6.4 cm soil water deficit) and well-irrigated plots (3.8 cm soil water deficit), during three years with variable rainfall. Irrigation increased yields in all hybrids, but in the absence of irrigation, yields were highest with the semi-flexible ear trait hybrid. In general, the hybrid with the flexible ear trait had lower optimal seeding densities than the other hybrids for each soil water regime. In general, kernel number was least affected by seeding density in the hybrid with fixed-ear trait compared to the semi- and flexible ear hybrids. The lowest levels of aflatoxin and of fumonisin contamination in harvested grain were associated with the flexible ear trait at all rainfall and irrigation levels, but there was no evidence that reducing stress by lowering seeding density reduced mycotoxin contamination. Inoculation with A. flavus resulted in much higher levels of aflatoxin and significantly higher levels of fumonisin contamination in grain of all hybrids under most conditions of rainfall and irrigation, suggesting that factors that promote A. flavus infection can affect production of both mycotoxins.
