We study the minimizers of the Ginzburg-Landau model for variable thickness, superconducting, thin films with high k, placed in an applied magnetic field hex, when hex is of the order of the ＂first critical field＂, i.e. of the order of ｜lnε｜. We obtain the asymptotic estimates of minimal energy and describe the possible locations of the vortices.

For the strongly coupled system of M ≥ 3 competing species：-△[（di＋∑j=1^Mβijuj）ui]=（ai-bi）ui-kui∑j≠iui,i=1,…,M,we prove the uniqueness of the limiting configuration as k →∞ under suitable conditions. Moreover, we prove that the limiting configuration minimizes a variational problem associated to the strongly coupled system among the segregated states with the same boundary conditions.

(R)-1,3-butanediol is an important pharmaceutical intermediate, and the synthesis of(R)-1,3-butanediol using green biological methods has recently been of interest for industrial application. Here, a novel strain QC-1 that efficiently transforms 4-hydroxy-2-butanone to(R)-1,3-butanediol was isolated from soil samples. Based on morphological, physiological, and biochemical tests and 5.8 S-internal transcribed spacer sequencing, the strain was identified as Pichia kudriavzevii QC-1. The reaction conditions were optimized to 35 ℃, pH 8.0, rotation speed 200 rpm, and 6:5 mass ratio of glucose to 4-hydroxy-2-butanone. Evaluation of the effects of 4-hydroxy-2-butanone concentrations on yield and cell survival rate showed that 85.60 g·L^-1 product accumulated, with an enantiomeric excess of more than 99%, when 30 g·L^-14-hydroxy-2-butanone was added at 0, 10, and 30 h in a 3-L bioreactor. Thus, strain QC-1 showed excellent catalytic activity and stereoselectivity for the synthesis of(R)-1,3-butanediol from 4-hydroxy-2-butanone.

Based on the hydrological data in the headwater region of the Kaidu River during 1972-2011, the multifractal process of runoff fluctuation was analyzed. Results indicated that, in the past 40 years, the overall runoff of the Kaidu River in Xinjiang has shown significant multifractal behavior. Its singular curve 1nχq（ε）-1n（ε） verified a favorable scale invariance over the entire time scale, r（q）-q proved that evolution of the runoff time series presented multifractal characteristics. Moreover, the multifractal spectrumf（α）-α curve was hooklike leftward which indicated that, compared to relatively large runoff events. And △f〈0 indicated that these relatively small events took the leading role; B〈0 explained the Kaidu River＇s daily-runoff ascending tendency presented during 1972-2011. Besides that, the multifractal behavior of the Kaidu River＇s runoff variability over four decades was also analyzed. Generally speaking, by decades, their four corresponding spectrum variations were not noticeable. These △α values showed larger runoff events occupied the leading position with some local values falling. During the 1970s to the 1990s, △f〈0 illustrated the probability of the daily runoff at the lowest point is always larger than that of the highest during three continuous decades. At the beginning of the 21 st century, for △f〉0 the trend presented was contrary from the 1970s to the 1990s. B values suggested an overall trend of increases during 1972-2011. Until the 21 st century, the runoff with a slightly descending tendency on the whole explained these relatively large runoff events taking the leading role for the Kaidu River; but sometimes, some small events also played the dominant role.

Six paddy soils of Shanghai, China, were studied after 120 days of anaerobicincubation at 25 deg C and 35 deg C. Four models, the effective accumulated temperature model, theone-component first-order exponential model (the one-pool model), the two-component first-orderexponential model (the two-pool model), and the two-component first-order plus zero-orderexponential model including a constant term (the special model), were fitted to the data of observedmineral-N during incubation using non-linear regression procedures. The two-pool model and thespecial model gave the best fits amongst the four models, and parameters in the special model weremore reasonable than those in the other three. Results showed that the special model gave a betterprediction of nitrogen mineralization under flooded conditions than the other three models.

比较康德的德福一致论与孔子的天命观

对于孔子所说的"五十而知天命"的诠释,两千年来没有确解。朱子对孔子"四十"与"五十"生命境界的所以不同的批注,说明了朱子之说是要从道德的当然之理进至所以当然的存有论之理。此即要从道德实践所理解的道德原则来说明存在界,这便关涉到个人的道德实践是否得到合理的回应之问题。借着康德所说的"德福一致"是实践理性的必然对象或目的,而此虽然也可以作为行动的意志的根据,但与道德法则作为实践行动的意志的决定根据,意义有所不同之论,可以比较出孔子与康德对于行义是否必然有合理的结果,此一问题上见解的同异。从孔子的自信"天生德于予"之说,可证践德者会有自己的实践行动必能带出合理的结果的肯定,但此一必然的肯定是属于宗教性的信仰上的必然,不同于以道德法则决定意志之为必然。这两个层次的必然性,是可以区分的,从孔子对于道之将行将废都视之为命,而在明知道不能行,仍要以出仕为义,而不可违反,可说明此意。
