An account of the all-artificial spore-collecting cultivation of Tiaoban-zicai (Porphyra yezoensis Ueda) in North China, carried out mainly after the Great Proletarian Cultural Revolution, is presented here. Scientific and technical workers integrating themselves with porphyra-cultivating peasants and learning the experiences of the masses, have eonducted investigations and thereby improved the cultivation techniques principally along three directions: (1) By employing comprehensive techniques in the culture of the conchocelis stage of tile porphyra, we have made at appropriate time the conchocelis discharge large numbers of conchospores, each shell (30—40 cm~2 in area) from 5 millions or more spores to as many as 80 millions in best cases. (2) Taking the discharge of large numbers of conchospores as the basis, and sufficient light intensity and vigorous agitation of the cultures as the conditions for materializing all-artifical spore-collectlng, we have developed a simple but efficient technique by em

An antiplane crack problem concerning a pair of coplanar cracks in a finite transversely isotropic elastic slab is considered. Using Fourier integral transform together with singular integral equation which can be solvel numerically by suing a collocation technique. Once the integral equation is solved, the relevant crack energy and stress intensity factors of the problem are given. The analysis present can be easily extended to include cases where there are two or more pairs of coplanar cracks in the slab.

The earthworm Metaphire posthuma were used as a model to assess the toxic potential of cadmium incorporated into the soil by environmental or human activities. The retention period of neutral red in the lysosomes of the coelomocytes was used as a biomarker. The viability of harvested coelomocytes by a non_invasive extrusion protocol was 93% with no alteration by the dye during experimentation. The control cells retained dye for 119 and 121 min in normal soil and KCl, respectively, whereas a linear decline in the retention time in the treated earthworm coelomocytes was observed. This illustrated that the presence of cadmium caused damage to the lysosomes of the coelomocytes.

鸡扒子滑坡位于四川省云阳县城东一公里处的长江北岸,它是老滑坡的部分复活。滑坡体积达15,000多万立方米,其中230万立方米已脱离滑坡进入长江洪水位以下,给航运带来了严重危害,造成了巨大的经济损失。本文根据详细的地表地质调查和钻孔资料,论述了老滑坡部分复活的地形地质背景,老滑坡的变形破坏过程及运动特征。结合1982年7月的暴雨特征,分析计算了孔隙水压力在滑坡复活中的作用。

The trajectories of the particles of the cross-equatorial air current moving in the Julymean 700 mb topographic field of the northern hemisphere are calculated, The correspond-ing annulus experiments are made for comparison wtth the calculation. The calculation and the experiment show that the trajectories of the southern currentparticles entering the low northern atmosphere and moving inertially in the barotropic atmos-phere deflect eastward and then turn back to the equator. The southwest current of themonsoon forms only when the air particles are affected by the Coriolis force and the forceof thermodynamic field of the atmosphere. In the formation of the southwest air currentof the monsoon the β-effect plays a certain role, but it is not a decisive factor. The results of the calculation and the experiment are compared with the real trajecto-ries of the drifted superpressure balloons observed by the satellite.

Increased sediment loads and sedimentation rates in rivers and streams have produced major disturbances to the society. However, while discussing f sediment transport and sediment induced problems focuses have often been given to those related to coarse sediments; tine sediment induces problems have been primarily investigated in bays and estuaries. In the case of Upper Mississippi River System (UMRS), increased turbidity and suspended sediment solids in the water column; heavy sediment deposition in channel boarders, backwater lakes, and side channels have shown to be problematic. Besides their impacts on human activities, fine sediments have also adversely affected water quality and flora and fauna of the river System. The total areas that affected, their accessibility, the amount, not to mention the contaminants involved, are complex challenges to the e1Yorts to restore the rivers’ functions. Many resource managers consider heavy sediment deposition in backwaters and side channels to be one of the most severe environmental problems on the UMRS. Large rivers are priceless resources and sedimentation plays a vital role in their sustainability. The example and experience learned from the UMRS can provide valuable information for management practices of other river basins.
